>> In 2026, AI is no longer something
people are just testing for fun. It has
become a part of our daily work,
learning, research, content creation,
and even decision-making. Microsoft
reported that in January 2026, the
global generative AI adoption reached
16.3% of the world's population, which
means roughly one in six people is
already using AI tools to learn, work,
or solve problems. And Stanford's 2025
AI Index reported that 78% of
organizations said that they were using
AI in 2024, showing how fast the shift
is happening. And now the real confusion
starts because today it's not just about
using AI, it's about choosing the right
AI tool. Some tools are better for
writing, some tools are better for
research, and some tools are better for
live information, file reading,
long-form explanations, and
productivity. And with names like
ChatGPT, Deep Seek, Gemini, Grok,
Claude, and Perplexity everywhere, a lot
of people are asking the same question,
"Which one should I actually use?" So
this is exactly what this topic is
about. In this session, we are going to
understand these six popular AI tools in
a simple and practical way. We will not
look at them only as trending names, we
will look at them based on the real use
cases. Which tool helps you write
better, which one is better for
research, and which one feels stronger
for technical tasks. We will also know
which one works well with files,
documents, and long content. And most
importantly, which one makes the most
sense for the kind of work that you
actually do. Here is what we will cover
in today's course. First, we will
understand why ChatGPT is often seen as
a strong all-rounder AI tool. Then we
will look at Deep Seek and where it
stands out for structured thinking and
technical support. After that, we will
explore Gemini and see how it fits into
the productivity and Google ecosystem.
Then we will talk about Grok and why
people discuss it so much for trending
and real-time style use. Next, we will
look at Claude and understand why it's
often preferred for long content and
polished responses. Then we will cover
Perplexity and why it's useful for
research and source-based answers. And
finally, we will compare them all
together and understand which tool is
best for each type of user. Before we
move on, here is something really
exciting. If you're someone who wants to
build real job-relevant skills in
generative AI, machine learning, and
intelligent automation, this program can
be genuinely helpful. It is designed to
take you from the fundamentals to
practical applications, so you just
don't learn the concepts, you also work
on hands-on projects, guided exercises,
and industry tools that help you build
confidence. You will also get to learn
from industry and gain exposure to
advanced topics like GenAI, agentic AI,
deep learning, NLP, MLOps, and
intelligent systems. What makes it even
more valuable is that it focuses on
helping you apply AI in real businesses,
workplace scenarios, and not just
theory. So whether you want to grow in
your current role or move into an
AI-driven work or build a strong
future-ready profile, this program gives
you the skills, practice, and
professional credibility to move in that
direction. So before we start off,
here's a quick quiz question. Which AI
tool is usually the better choice when
you want fast research answers with
sources? Is it A, Claude, B, Perplexity,
C, Grok, or is it D, Deep Seek? Let us
know your answers in the comments below.
Hello everyone and welcome back. Right
now, one of the biggest questions people
have is very simple. There are so many
AI tools everywhere, but which one
actually helps the most in real life?
Well, every few weeks a new name starts
trending. One tool is called the best
for writing, another is called the best
for research, another is said to be
fast, and another is said to be smart.
And because of that, a lot of people
feel confused. They don't know which
tool is actually useful for their work,
their studies, or their daily tasks.
This is exactly why comparison matters
most right now. This is not just about
famous names, it's about practical
value. Which one helps you write better,
search faster, solve problems clearly,
and understand files properly, save your
time in running daily routines. So that
is what makes this topic so relevant.
Whether you're a student, a creator, a
working professional, a business owner,
or someone who simply wants a better
assistant for everyday use, this
comparison can help you understand what
each tool really brings to the table. So
instead of getting lost in hype, we are
going to keep this simple, practical,
and easy to understand. We will look at
what each tool does, where each one
feels limited, and where each one makes
more sense depending on what kind of
work you do. So let's now get familiar
with the six tools in a simple and easy
way. First, we have ChatGPT. So this is
the tool that many people already know
and use it for writing, brainstorming,
learning, planning, and general
day-to-day help. Next, we have Gemini.
Gemini is closely connected to Google's
world, so it becomes especially useful
for people who work a lot with Docs,
Gmail, Drive, Sheets, and other Google
products. Then we have Claude. Claude is
often known for giving calm,
well-structured, and detailed responses,
especially when the task involves long
reading or careful writing. After that
comes Perplexity. Perplexity is commonly
used more in smart research helper
because it helps focus strongly on
finding answers with sources and current
information. Deep Seek has become
popular because many people see it as
strong for structured problem-solving
and technical tasks. It's also being
talked about for a lot of value and
performance. And finally, we have Grok.
Grok often comes into the conversation
when people want faster access to
trending topics, real-time updates, and
a more live internet feel. So even at a
quick glance, these tools are not all
trying to win in the same way. Some are
stronger for writing, some feel better
for research, and some work better for
long documents. Some also feel useful
for technical tasks. So that is why
comparing them properly matters. So now
that we know who the six players are,
let us move on and understand how this
comparison will be done fairly. So
before comparing anything, there has to
be a fair method, otherwise the whole
comparison becomes opinion instead of
something useful. So this comparison
will be based on the things people
actually care about in real life. First
is writing and everyday work. Can the
tool really help with emails, captions,
scripts, notes, summaries, and daily
tasks in a way that feels natural and
usable? Second, we have research and
current information. Can this help find
updated answers, compare things clearly,
and make research easier? Third is
reasoning and problem-solving. Can it
handle tasks that need step-by-step
thinking instead of just giving a quick
reply? Fourth is coding and technical
help. Even for beginners, can it help
explain things clearly, fix errors, or
make technical tasks feel less
confusing? Fifth, we have understanding
documents, images, and longer content.
Can it handle PDFs, screenshots,
reports, charts, and long inputs
properly? And then finally, we have
speed, usability, and practical fit.
Because even if a tool is powerful, it
also need to feel easy and useful in the
real world. So this method matters
because the best writing tool may not be
the best research tool. The best tool
for long documents may not be the best
one for quick answers. And the best tool
for daily use may not be the strongest
one for technical work. So instead of
forcing one answer into another, it
makes more sense to look at each
category one by one. So now that this
method is clear, let's move on to the
first category that most people care
about, and which is writing and everyday
work. So this is where most people
begin. They open one of the tools and
ask it to write something. It could be
an email or social media caption or a
blog outline. It could also be a
LinkedIn post, a script, meeting notes,
resume point, or even a simple
explanation. So the first thing that
really matters is this, how natural and
useful does the response feel? A good
tool in this category should not give a
long answer, it should give a clear
answer. It should understand tone, keep
the responses organized, and make the
output feel ready to use. In this area,
ChatGPT feels like a strong all-round
option because it's flexible across
different styles and tasks. Claude often
stands out when writing needs to feel
polished, calm, thoughtful, and a little
more refined. Gemini can feel especially
useful when the work connects with daily
office tasks and Google ecosystem.
Perplexity is less about stylish writing
and more about helping gather
information quickly, which can still be
useful while building written content.
Grok may feel fast and current,
especially for prompts related to trends
and ongoing conversations. Deep Seek can
do well with the writing. Deep Seek can
do well when the writing is more
structured and logic-focused. So the key
difference here is not who writes the
longest answer. The real question is
which tool gives the most usable answer
for the kind of work that people
actually do everyday. So now that the
writing and everyday use is clear, let's
move on to a category that matters even
more when the people want facts,
updates, and quick learning, research,
and current information. So this is
where the comparison becomes even more
interesting because today people are not
only using the tools to write, they are
using them to search, compare, learn,
understand trends, and check facts to
get quick summaries. And this is done
without opening too many tabs. And this
is where the tools start feeling very
different from one another. Perplexity
is often the first name people mention
in research conversations because it's
focused on giving answers with sources
and making information gathering very
fast and direct. Grok also becomes
relevant here because it's often linked
with trending topics, ongoing
discussions, and faster access to what
is actually happening right now. Then we
have Gemini. Gemini feels useful for
people who are already working with
Google tools and want research help in
the same environment. ChatGPT has also
become a part of this conversation
because many people now use it not only
for writing, but also for exploring
topics, understanding concepts, and
organizing information clearly. Claude
can be helpful when it comes to research
and it needs to be turned into a more
thoughtful and deeper explanation.
Deep Seek also enters the picture when
users want structured responses and
cleaner breakdowns. So in this section,
the difference becomes very clear. Some
tools feel more like answer generators
and some feel more like research
assistants. And some feel stronger at
gathering, while others feel stronger at
explaining. So that is why this category
matters so much in daily life. So now
that the research and the current
information are clear, let's move on to
the next category, which is on reasoning
and problem-solving, where the real
depth of a tool starts to show. So this
is the point where the comparison starts
to get really serious because a tool can
sound impressive in the first few
seconds and still not be really helpful.
So reasoning is not about giving the
fastest reply, it's about understanding
the situation properly, breaking it down
step by step, and then giving an answer
which actually makes sense. So whether
it's solving a tricky question,
comparing options, planning something
clearly, or handling a prompt with
multiple layers, this is where the real
quality of a tool starts to show. A
strong tool in this area doesn't rush.
It stays organized, keeps the response
clear, and helps move from confusion to
clarity. So, instead of throwing out
some random points, it builds the answer
in a way that feels dependable. So, that
matters because in real life, people are
not only using these tools for fun
questions, they are using them to make
decisions, understand concepts, solve
work problems, and save time on tasks
that really matter. So, the real
difference here is simple. One tool may
give a fast answer, but another gives an
answer which feels more reliable, more
structured, and easier to trust. And
when the task becomes more complex, that
difference becomes much more important.
So, this is exactly why reasoning and
problem-solving is one of the most
strongest ways to judge which tool is
genuinely useful and which one just
sounds good at the first glance. So, now
that this part is clear, let's move on
to another important category that a lot
of viewers are curious about today,
coding and technical task support. So,
even people who are not fully full-time
developers are now using these tools for
technical help. So, they are using them
to understand code, fix errors, write
formulas, help explain commands, build
small projects, and simplify tasks that
could otherwise feel really difficult.
So, this part is not only for coders,
it's also for learners, beginners,
students, and working professionals who
want support with technical work. So,
the most important tool here is not just
the one that writes code quickly. The
better tool is the one that explains
clearly, reduces confusion, and makes
the task easier to understand. ChatGPT
is widely used in this area because many
people find it flexible for explaining,
generating, correcting, and breaking
technical things into simpler steps.
Claude also enters this conversation
because it often handles longer context
well and can stay clear while explaining
bigger tasks. Deep Seek gets a lot of
attention because many users talk about
it for structured technical work and
value-focused use. Gemini can be useful
when the task connects with wider
Google-based work. Perplexity can still
help when the goal is to search for
technical information and compare
reliable answers. Grok can feel useful
when the task connects to current
discussions or quicker online
exploration. So, the key point here is
simple. A strong technical assistant
should not make things more complicated.
It should make them clearer. It should
help people feel less stuck and more
confident. So, now that coding and
technical help are clear, let's move on
to a category that has become very
important in modern use, understanding
documents, images, and long content. So,
this category matters because people no
longer use these tools only for short
questions. Today, people are uploading
files screenshots reports resumes
charts, slides, and PDFs, and expecting
the tool to understand them properly.
That changes everything. A tool that can
handle uploaded content well becomes
much more useful in everyday work, and
it's no longer just a chatting tool. It
starts becoming a work assistant. In
this area, Gemini becomes especially
relevant for people who are already
working with files inside Google tools.
Claude is often talked about for how
well it handles long reading and
detailed content. ChatGPT is commonly
used for document-based talks, file
summaries, and learning support. Grok
enters the discussion when people want a
more current and connected experience
across different kinds of inputs. Deep
Seek can also be useful when the task
depends on structured handling and
careful breakdowns. Perplexity can be
helpful when the uploaded content needs
to be connected back to source research
or broader information. So, the real
question in this category is not just
whether the tool can read the file. The
real question is whether it can
understand the context, return something
organized, and save real time. So, that
is why this category matters so much in
office work, study routines, content
creation, or day-to-day productivity.
So, now that the documents, images, and
the long content is covered, let's move
on to the final section where everything
comes together, practical fit, ease of
use, and final verdict. So, after
looking at all these categories, the
biggest takeaway becomes very clear.
There is no single perfect tool for
every person, and that is actually the
smartest conclusion because a better
question is not which tool is best
overall. The better question is which
tool is best for all kinds of work that
someone actually does. If someone wants
a strong all-round tool for daily
writing, planning, learning, and general
tasks, one option may feel like the
right fit. So, if someone wants a
stronger research and faster
source-based answer, another may stand
out more clearly. And if someone wants a
strong long-form reading and detailed
understanding, another may feel more
dependable. So, if someone lives inside
the Google ecosystem, one tool may
naturally feel useful. And if someone
wants a quick trend-based exploration,
another may seem very appealing.
And if someone is looking for strong
structure with the help of better value,
so the smartest way to end this
comparison is not by forcing one winner
for everyone. The smartest ending is to
match the tool to the use case. And that
feels more honest, useful, and more
practical. So, the final message is
simple. Do not choose based on the hype,
trends, or the loudest option online.
Choose based on what is actually helping
you save time, improve work, and make
daily tasks easier. So, now that the
overall picture is fully clear, the live
demo section will make it even more
sense because the real outputs can now
be judged against the strengths and the
use cases we have just understood. So,
let's move on to that.
Hello, everyone, and welcome back. I
have all the six tools open here, which
is ChatGPT, Grok, Perplexity, Deep Seek,
Claude, and Gemini. And instead of
talking about all of them in a general
way, I'm going to open them all one by
one and use them in a way that most
people actually do. I want to see how it
feels when the page opens, how quickly
they get to the point, and how clearly
they answer, along with which which one
feels most useful for the kind of work
that people are actually doing on an
everyday basis. So, I'm starting with
ChatGPT here first because it works well
with the baseline for this whole
comparison. And then I will move on to
the tools that feel stronger with the
current information, structured
thinking, file work, and polished
output. So, as you can see, I've opened
ChatGPT here first because it's one of
the most easiest place to start when the
goal is everyday writing, planning, and
general productivity. And OpenAI's
current ChatGPT help pages show that the
uploaded files can be reused later
through the library on web. So, the
first thing I'm typing here is this,
write a
short for
a beginner who just completed completed
a
course. So, now while this loads, what
I'm looking for here is balance. A
strong ChatGPT answer will usually feel
polished, clear, and ready to use
without sounding too stiff. So, I want
it to stay inside the word limit,
keeping the tone warm, and avoid
sounding like a template. And if the
answer feels like something that a real
person could post one after a small
edit, that is a very good start. So, now
that the writing side is clear, I'm
staying inside the same chat and pushing
it one step further with a very natural
follow-up. Make it sound slightly
more more personal.
So, the second line matters because it
shows whether the tool can actually
listen to the style correction instead
of starting from scratch. So, if the
next version becomes more natural
without losing the original meaning,
that tells us that the flow is smooth
and usable. So, now that the basic flow
is clear, I'm going to come back to the
ChatGPT a little later for file work
because that is also one of the most
stronger areas. But before that, I want
to move to a tool that is much more
associated with what is happening right
now. So, as you can see, I've opened
Grok over here. So, I'm opening Grok
next because xAI's current product
materials lean heavily into real-time
research, voice, and vision. So, it
makes sense to test it on something
that's fresh and fast-moving rather than
on a quiet writing task alone. So, here
is a prompt that I'm typing into Grok.
Why are the AI agents trending? So, now
while this loads, what I'm expecting
from Grok is freshness. I want the
answer to feel current, faster, and
connected to live conversations. So, if
it brings in recent developments keenly
and makes the explanation feels more
simple instead of heavy, that is where
Grok starts to feel looking useful. So,
if the tone feels a little more direct
and internet-aware, that also fits for
this kind of position. So, here's what
Grok is aiming for. Now, I'll be adding
an extra line to the same chat. Now,
give me a more beginner-friendly.
So, this follow-up matters because a lot
of tools can answer quickly, but not all
of them can soften the tone properly for
a beginner. So, if Grok keeps the answer
current while making it easier to
understand, that is a good sign. So, now
that we've checked the real-time angle,
I'm moving from the tool that people
often open when they want sources and a
research-style answer right away. So, as
you can see here, I've opened Perplexity
next because its help center explicitly
supports file attachment and follow-up
context inside the same thread, and the
product is widely centered around
search-style answer. So, I'm typing this
into Perplexity. Why are the agents
trending in 2026? So, now as this opens
up, what I'm expecting here is not just
a neat answer. I'm expecting a more
research-like result. I want to see
whether the answer feels grounded,
whether it points to sources naturally,
or whether it sounds like something I
could use to understand a topic quickly
without hunting down it. I want to see
whether the answers feel grounded,
whether it points to sources naturally,
and whether it feels like something I
could use to understand a topic quickly
without hunting around on. So, as you
can see, this is the result we have
obtained, and it's more research-like.
So, now I'm following that with this,
compare ChatGPT, Grok, and Perplexity
for someone who mainly wants fast
research and trustworthy references. So,
keep it a short table. This is a very
good second step because it shows
whether the tool can stay organized
after the first answer and turn that
information into something more
unstable. So, if the table is clean,
practical, and easy to scan, Perplexity
immediately starts with feeling valuable
for research-heavy work. So, now that
the search and sources side is clear,
I'm moving to the tool I want to use for
structured thinking and technical
clarity. So, as you can see here, I've
used Deep Seek for the same. I've opened
Deep Seek here because its current chat
page describes it as an assistant for
coding, content creation, file reading,
and long context work. And Deep Seek's
own docs also note web search on
chat.deepseek.com.
So, the first thing I'm typing here is
this. I have 2 hours every weekday. So,
now what I'm looking for here in Deep
Seek is structure. I want the answer to
feel well organized, sensible, and
step-by-step. A strong result should not
just throw subjects into a calendar. It
should divide time properly, keep the
schedule realistic, and explain the
logic in a way that feels useful. So,
now that the planning side is visible,
I'm staying in Deep Seek and asking
something very small but practical.
Explain this Python code for for
beginners. So, now I'll go and add the
code. So, now this is where clarity
matters. More than flashy language, the
best answer here is the one that calmly
explains that numbers is a list and max
numbers finds the biggest number and
that the output is nine because nine is
the largest value in the list. So, if
Deep Seek handles that in a very clean
and non-confusing way, it starts looking
very strong for learners and technical
explanation. So, now that the reasoning
and coding side is clear, I'm moving
into the part that feels much more
closer to real office work, which is
uploading a file and seeing what the
tool actually does with it. I'm opening
Claude for the file-heavy part because
Claude support pages show artifacts for
substantial stand-alone content and
documents that Claude can create and
edit files directly. That makes it a
very natural place to test long content
understanding and turning that content
into something very usable. So, I'm
uploading the same file here that I will
also use in the next few tools once it's
attached. So, I'm typing the following.
Read this file and do three things. So,
when I've uploaded the file, I'm
expecting that Claude is calm, polished,
and understanding. I want a one-line
summary to be accurate and the three key
points to feel more important and the
week section to be specific, along with
which the simpler rewrite to still
preserve the meaning. And if Claude
handles the file carefully and the
response feels thoughtful rather than
rushed, that is exactly where it starts
standing out. So, now I'm taking this
file one step further. Turn this file
into a five-slide presentation.
So, this is a strong check because
Claude's artifact-style workflow is
supposed to be good at producing larger
reusable outputs. So, if the outline
feels clean, presentation ready, and
easy to speak from, that tells me that
the file has not just been read, it has
been transformed properly. So, now that
the polished long content side is clear,
I'm moving on to the tool that should
feel especially comfortable when the
work starts looking like documents,
study material, and workspace-style
productive. For the same reason we have
Gemini. So, I've opened Gemini here
because Google's help pages show that
Gemini app support file uploads that can
handle up to 10 files in one prompt and
can create things like charts and
uploaded data. So, the Gemini Help
Center also currently points people to
features like Canvas and Deep Research,
which makes Gemini a good fit for
structured productivity-style tasks. So,
I am uploading the same file here and
typing, read this file and give me a
simple explanation.
So, now what I'm expecting from Gemini
is a clean, study-friendly response. I
want it to feel organized, clear, and
practical. So, if the explanation is
simple, the bullet points are neat, and
the revision questions are actually
helping someone remember the content,
Gemini starts looking very useful for
learning and everyday office use. So,
now I'm adding one more follow-up here.
So, like I said, here are the bullet
points which were needed. So, coming
back to the prompt, now turn the same
content into So, the second pass here
matters because it checks whether the
tool can shift the format without losing
the original meaning. So, if it moves
from study mode to an email mobile mode
smoothly, that tells me that it's
flexible in every practical way. So,
[snorts] now that Gemini's handled the
learning and productivity angle, I'm
moving back to the file workflow in a
more research-focused environment, which
is Perplexity. So, I have returned here
to Perplexity and attaching the same
file here because Perplexity explicitly
supports file uploads from the attach
button and keeps the context for
follow-up questions in the same thread.
So, I'll go ahead and type, read the
following file. So, what I'm expecting
here is a sharper research-style read on
the file. So, I want to see whether
Perplexity treats the file a little more
like evidence, notices that there's
something feeling unsupported, and gives
a more verification-focused answer
instead of just rewriting the text
nicely. Then I will be adding the
following. Give me three follow-up
questions.
So, as you can see, I have not really
attached a file yet. So, this is where
Perplexity can feel especially useful
because a strong answer here should not
just summarize. It would help push
thinking forward. So, now I'm going back
to ChatGPT for the same uploaded file.
Yeah.
So, for your information, ChatGPT's
current web experience includes file
reuse through the library, which makes
it more useful for the same material and
it needs to be worked on again and
again. So, I'll be typing the following.
Read the
following file and turn it into So, what
I'm looking for here is flow. I want the
script to sound usable out loud, not
like a report pasted into a chat. So, if
ChatGPT keeps the meaning but makes the
language smoother and easier to present,
that becomes very helpful for content
creation and presentation work. So, now
I will be following it up with this.
Make the same script shorter and more
energetic.
So, this is an important final check
because it shows whether ChatGPT can
reshape the same content for a different
speaking style without losing its core
message. So, now let's move on to the
website feel while everything is open.
So, at this point the differences start
becoming very visible even without
saying much. ChatGPT feels like a
flexible all-rounder for writing and
reusable content. Grok feels more useful
when the topic is fresh and moving fast.
Perplexity feels the strongest when the
sources are research-style and clarity
matters. Deep Seek feels very solid when
the structure thinking and technical
explanations are needed. Claude feels
strong when the content is long and
needs to be turned into something
polished. And Gemini feels comfortable
when the work starts looking more like
learning material, office material, or
structured productivity.
All of that lines up with what the
companies are currently surfacing in
their product materials and their help
pages. So, after opening each one
properly, typing real prompts, pushing
them through writing, current
information, structure planning, and
small code explanation, file
understanding, as well as follow-up
work, the answer becomes very clear. The
better choice is not always the most
talked upon one. The better choice is
the one that feels most useful for the
kind of work that someone actually does.
So, that is the foundation of this
comparison. So, by the end of this
session, you may have had a clearer idea
of what AI tool actually fits your work,
your learning, and your daily needs.
