## Summary

This video demonstrates how to use Botpress to create an AI chatbot that can be trained on custom data, such as a website or documents. The tutorial covers creating a basic bot, adding a knowledge base, and configuring it to fall back to ChatGPT for unanswered questions. The platform allows for easy integration of additional features like audio and video.

### Key Points

- **Adding Knowledge to Bot** [4:49] — The tutorial shows how to add knowledge to the bot's default knowledge base by creating a new knowledge base and adding documents or text.
- **Enabling Knowledge Answering** [6:05] — To make the bot answer questions based on its knowledge base, you need to enable the 'knowledge answering' feature in the raw input card.
- **Adding Various Data Types** [6:38] — The knowledge base can include web pages, text documents, and other file types like PDF, HTML, or TXT.
- **Testing the Knowledge Base** [7:18] — The bot is tested with a simple question from the custom knowledge base, and it correctly answers that Harry's best friend is Rohan.
- **Handling Unanswered Questions** [8:26] — The video shows how to configure the bot to use ChatGPT when it cannot find an answer in the knowledge base, by setting up a fallback mechanism.
- **Fallback to ChatGPT** [10:45] — The bot is configured to fall back to ChatGPT for questions it cannot answer from its knowledge base, using a variable to store the user's input and output.
- **Adding AI Generated Text** [11:03] — The tutorial demonstrates adding an 'AI generated text' node that uses the user's input to generate a response from ChatGPT.
- **Adding Audio to Bot** [13:40] — The bot can be enhanced with audio files that can be played in response to user queries, as shown with an 'Let's ask AI' audio file.
- **Advanced Bot Configuration** [15:03] — The video shows how to configure the bot to only use ChatGPT when the knowledge base fails to provide an answer, using an expression to check if the knowledge agent responded.
- **Publishing and Sharing the Bot** [19:00] — The bot can be published and shared via a link, allowing users to interact with it on any website.
- **Embedding on Websites** [20:34] — The bot can be embedded on any website to chat with users, providing a custom AI assistant.

## Transcript

We have all used chat gpt but if I tell you to make a bot which works on your given knowledge base
That means you have some data and you are trained on it, then how will you make it?
Well, in today's video we are going to see about a platform like this which will help you to make chatbots very easily
Then you can also put those chatbots on your website
The best thing I found about this platform was that it is very easy to make a bot
you can do something like
you have given a website
you can tell this bot that if there is any information in this website
then I want the answer to my question
and it will pull the answer to your question
according to that knowledge base
then we can also configure that
if your bot does not get the answer
then it will ask from chat gpt
and finally you will get what you want.
We can add a lot of additional elements to it.
We can add audio, we can add video.
If you want to play an audio in English,
then you can add this answer.
Let's move to chat GPT.
You will get to see such things there.
We explore this chat bot.
I will show you how to sign up.
How to make a basic bot
and then if you want to make an advanced bot on your knowledge base
how will you make it
let's go to the computer screen
let's get started
so guys as you can see I have come to my computer screen
and I have given a link in the description
by clicking on it you will reach here
and botpress.com will open
you can make a chatbot by using this let's say you have your own data,
you have a knowledge base, you have a lot of data, you have proprietary data, you can't always give that data to chatgpt and ask the question answer,
I'll tell you why, let's talk about a website, ndtv.com, I will tell you about ndtv.com, if you have heard about NDTV, then you must know, if I have written here
site NDTV.com, you are seeing how many results have come here, you will never want to give
the data of so many web pages after storing it, you will not want to give it to chargeGPT,
why you will not want to give, because if you give data like this, then it will take a lot of time,
plus there are limits of chargeGPT, there are limits of your tokens, it will never take your data completely.
So what you have to do is that you can train a bot on botpress, you can say that put NDTV.com in my knowledge base.
And NDTV.com will be put in your knowledge base, then you can ask questions, if the answer to your question is not given, then you can configure your bot like this.
If the answer to the question is not there, ask chargegbd, chatgbd will tell you.
So let's continue with Google, let's sign up.
And the signup process is very straightforward, let's continue with Google.
If you want, you can continue with GitHub, I will continue with GitHub too, okay.
Just so that it becomes easy, and here I will authorize Botpress,
you will be redirected to app.botpress.cloud, and these are all your bots which you can make by clicking, all the bots you will make
will be shown here, but I will click on plus here and make a new bot
and after clicking on plus, I will start editing my bot
I will make the first bot and I will recommend you to make this bot
Learn Botpress, with this you will get to learn botpress
if you click on use template, then WordPress will teach you how to use WordPress.
So I have clicked on use template and finally I have come here, I also don't want to play with this bot, I will close it and if I want I can rename my bot, I will make a new bot.
Now I can make a bot by using any template, so here I will on edit And after this, my other two templates will also be unlocked
The first board you have to make
You have to make this one, the one with the pod press
You both will not be able to make this
Because the pod press wants you to learn first and then make the board
So I can start from scratch now
By the way, they have a lot of templates available
Like you want to make a messenger board
I click on use template
Like you want to make a messenger board
Or let's say you want to make a bot related to Instagram, you can do all those things, but in this video I will tell you the basics and I will make a very useful bot for you, listen to the use case, what is the use case, the use case is that I have a website ndtv.com from which I read the news, you may read from someone else, there are many, there is Times of India, there is Republic Republic, and many more news channels.
If you want to see the basic news, you can go to a website.
And once you go to that website, you have one option that you read all the news.
Definitely, I am not telling you any replacement for that.
Let's say I want to know how much money did the movie earn?
I can't tell you the chat. Let us say I want to know that how much money has the movie earned.
I can't tell you the chat gpt because it is news. So I have to ask NDTV in a way.
I have to train on NDTV and I don't want to take so much hassle. Who will take so much time to train on NDTV chatbot by writing code.
So now come to the botpress. What you do here is start and see here i am zooming you can scroll and zoom and pan like this
now see here it is written this bot is empty please add
knowledge in the default knowledge base
and cards in the node, so what i will do is delete this node
and click on delete and confirm
now there is a start point and an end point
listen carefully, now right click on standard node
add a new card
after adding the card, I will choose
raw input, so you guys write raw here
and select raw input
and you can see here that I have selected raw input
so as soon as I have selected raw input
I will say start
then after that raw input
will give the user, that means user will give any answer
I will ask the user, what do you want
what do you want to
ask and after that
i will give the output here
so here i will
start this bot
here you can click on new conversation
and i will ask
hey how are you
i have asked a basic question
it will not be able to answer
what do you want to ask, I have
Maybe here in the question, what do you want, I have done a little spacing wrong, let's fix it, now ask me what do you want to ask, I will say how are you, okay, and it will end after this, nothing happened, okay, in total, the thing is that the time is over, your bot has not done anything, so if you want your bot to do something then click on raw input and you can see this
click on card and check enable knowledge answering
this will enable you to add a knowledge base
so i will add a knowledge base here
for this i will click on default knowledge base
and if you want you can add a new knowledge base
so i will click on knowledge base
and if you want you can add things in this default knowledge base
or you can make a new knowledge base by clicking on this book
so you can create and delete knowledge base as much as you want
I will use this default knowledge base only
I will do one thing, I will make a new knowledge base
I will keep it's name as Harry, ok this is the data given by Harry
what all you can add in knowledge base
you can add web pages, web search, you can add text documents
so I can do one thing here, I go to documents,
I will add a document, here I can drag any kind of PDF, HTML, TXT.
I have a file called Jod.txt, I will show you what this file is,
I will open it and show you, I will select it,
in Jod.txt I have written,
Jawans music was given by Harry's father who is a very nice person.
His favorite fruit is watermelon.
I have written a very random thing, okay.
And I will close it and I will confirm it.
This document, jod.txt will be uploaded.
Remember, Harry's father's favorite fruit is watermelon, okay.
So I have written here.
Then I will click on knowledge base.
I can add text documents, documents, many things here, okay. So I can click on add base, I can add text document, documents I can add many things, so I will click on add document
I can add anything here, or I can do one more thing
I can delete this knowledge source
I can disable it and delete it, disable means
Temporarily if I want to disable it
I will click on plus knowledge base and click on text document
I can type here, Harry's best
Friend is Rohan
ok, let's say I wrote this
after writing this
what I will do is
this data is my knowledge base
now I will show you one thing
I will go to bot again
I will start a new conversation and ask
who is Harry's best friend?
A very simple question from my knowledge base
Let's see if he can answer it or not
And here he told me that Harry's best friend is Rohan
He also told me where he came from
See 1 is written
He said that in the rich text you gave me
It is written that Harry's best friend is Rohan
Okay, so we have done all these things
Now what I am going to do is a very amazing thing.
I will show you one thing, just
to make you check that he is not able to tell this thing.
If you write here
How much did
Jawan earn?
I asked a very
basic question that how much money did Jawan earn?
Now, he will not be able to tell.
He will say that no valid answer found.
The knowledge base you have given, related to this, so now what will he do, he will end it, but now I will show you that if I come to my knowledge base, which is hairy, add from url and here i will write https://www.ndtv.com
and i have confirmed it and you can see here
that it has been indexed, now see i have
copied this news article and put it here, ok
and it has been indexed, i will close it here
and now you can see i will ask here that
i will come to main and see here which question
has been answered as a producer who is producer of jawan
so I wrote here who is producer of jawan
and you guys see here that as soon as I write who is producer of jawan
and it came here that producer of movie jawan is shahrukh khan
you see here that he got knowledge from here
so in this way you can add multiple pages you can see here, from here, from this one, he got the knowledge
so in this way you can add multiple pages and all the pages he will parse
like ndtv.com is very enormous, you can add specific pages and they will be parsed
in your knowledge base, so if I add the whole domain, then he has parsed only a few pages
which is shown here, it is not possible to parse all the pages because there are millions of pages
but again, you can give the link of whatever you want and you can pass it
and here you can add as many pages as you want
if you have any information in pieces
what I mean to say is that
if you have any information in a document
you can hold your business documents
and ask questions about your business
and it will tell you how to analyze
so assume you have any data related about your business, he will tell you how to analyze
so assume you have some data related to your business, even if it is a small business
or a small shop, ask him about it and ask him questions
that how can I improve, which products should I sell, how can I expand my business
sky is the limit, so this is what happened here, thing now suppose he didn't get any answer
suppose i ask him
how did planet earth
came into existence
i asked him
he won't be able to answer
because he doesn't have any knowledge
see no valid answer found
so if i want to
tell chat gpt
so what i will do
i will add a new standard node
understand it step by step
I will add a card and here I will write
AI and AI generated text
I have written AI generated text
I will write another card
and this AI generated text
I will add a simple text
I will add a simple text after this generated text
So I will add a text here
And after this what I will do is
The input of this will come here
I will link this card with this and I will link this card with this
Okay from the end
So it will come here
Standard input will be found in the knowledge base first
If not found in the knowledge base, then it will come here
And this standard 2
both are red because I have to give prompt
now see when raw input is here
understand my point carefully
when raw input is here
whatever user will input you can store it in a variable
so I will store it in a variable
I will name it as Harry input
and I will create this variable
this is saved in Harry input now I will create this variable this is saved in Harry input
now I will say that my AI generated text
will take
Harry input
as an input
and what will output do
I will say that the output will be
named as Harry output
ok I have created a variable
so it will save the output in Harry output
and this text which is message to send, which the bot will say
what will that be? Harry output, so I have selected Harry output
and that's it, now let's see, I will ask him how did planet earth came into existence
let's start a new conversation and ask him the same question
so I asked him this question, first of all he will search in knowledge base
and in fact he won't get it
in knowledge base
and after this
as soon as he won't get it in knowledge base
he will move ahead
and in AI generated text
he will go to the Harry input
so i guess i have just started
first i should start the conversation with a hi
after that we can ask him this kind of questions I guess I have just started First I should start the conversation with a hi
After that we can ask questions like this
Now AI task is run and you can see that AI will tell us about it
Let's wait
And see this
Origin of planet earth is a fascinating subject that has intrigued scientists and philosophers for centuries
It has told me the whole thing
Means AI is also connected to it
so here he told me the summary
that this is how your work is done
so i will auto close it
and you can ask
any number of questions
and your work will be done
now listen to me carefully
what is the problem in this bot, it is a very good bot
there is no problem, if i want i can
also put an audio here
suppose i want to play a music or i record an audio
and upload it here, infact i will do one thing
i will add a card, here audio
and in audio i will drag an audio file, it will be named
AI
AI, initializing AI
let's ask AI, initializing AI, let's ask AI, ok
text to mp3 on youtube, sorry on google, may be i will get a tool
in which i can write let's ask AI, may be i will get its mp3
can i download it as an mp3, yes i can
now what i will do is, i will drag it here, you see how i will drag it
it will be uploaded mp3 and let's ask AI
and now let's see
if I ask anything, let's say I ask him
How did planet earth came into existence?
Will he play or not? We will see now, okay?
So he doesn't know the answer to this question, okay?
He said what do you want to ask? I started the conversation
Then what do you want to ask, I started the conversation then what do you want to ask, it said
how did planet earth came into existence
no, it didn't
see this, let's ask AI
so if I had kept this earlier, let's ask AI would have been played earlier
so I can send this kind of audio
I can send audio here
which is a very good feature
so you can do this kind of work with the help of botpress
Now the problem I told you that there is a problem with this bot
And we will solve it and that is
When there is something in my knowledge base, like I ask
Who is Jawan's producer
So he will also ask this from AI, that is once
I have actually started my conversation, I should write high
And when he asks what do you want to ask, then I should write.
So, you see, who is Jawan's producer, if I write, so he told me that Audley is the producer of movie Jawan, and where did he pick it from, he picked it from here,
and let's ask AI, and Jawan's producer is Dilrau, this is what AI told me so I don't want AI to tell me, I don't want this
I want in fact that
I will delete this link
I will say that if my knowledge base can't tell me
then AI should tell me, you understand? there is a difference
so I will make a new standard note here, I will add card
and I will write expression here
and I will remove always from this expression
okay, I don't want to keep it always true and i will write expression here and i will remove always from this expression
i don't want to keep always true
i will delete this and i will write
turn, turn is an object
and i will write here .knowledge agent
.responded, it means
that did the knowledge agent respond or not
if it didn't, I have put a note that if not, then what to do
then come here, then come here
otherwise what to do, otherwise end it
so you see here that it will go on this card
and it is written here because it is not connected to another node
ok so here we will connect this to end,
let me cut this, actually there are two things, one is that
with whom you want to connect this and then if it is not resolved then what you want to do,
okay, so let me zoom out this, I will zoom out slowly and I will connect this thing from here,
okay, now you see, now I will start the conversation again, I will say hi,
first I will write hi and then I will write
how did planet earth came into existence, now AI will tell you but if I ask
who is Jawan's producer, okay, and
I will enter and
actually Jawan's producer is both Otli and SRK.
So, sometimes Otli is telling and sometimes SRK is telling.
So, don't get confused.
Therefore, I don't have...
So, you can see Otli is the director of movie Jawan.
Praise Charu Khan is a serious producer.
However, there is no specific mention.
So, it told me that the answer came from knowledge base.
And this time, AI has no role.
But AI did nothing.
Which is a sign that this card is working for us
now if I ask him about planet earth, how did planet earth came into existence
suppose I ask him
and this conversation started and what do you want to ask
now I will say how did planet earth came into existence
and now you see
now he is going to AI, no you will see now it is going to AI
no valid answer found
and
you can use many more cards
you can make a complex bot
but this is a very basic one
you can train it on your knowledge base
you can use it for free
which is the best thing
about wordpress
you have to try it out and wordpress you should try it out
and as soon as you try it out you will know about its powers
and their documentation is very good
as i told you i was able to read the documentation
for an hour, less than an hour in fact
i read it in few minutes, enjoyed the documentation
and after that i was able to do all this
if you want to use this in detail you should be able to
read the documentation
or wordpress
docs and you can see here
that you can read the documentation
of wordpress and
you can use this bot very well
now I will publish this
and tell you about the bot, I will click on publish
so that I can publish this bot
and it is publishing
let's wait
waiting for it to publish
and here it is
published successfully
now I will click on share
I can share my bot
and you can see my bot is here
vr powered by botpress
I will write here hey
and I wrote here
Now it looks like a real chatbot
And it is thinking
And finally it is asking
Who is the director of Jawan?
I asked him who is the director of Jawan movie
and because I have given him this webpage, he knows who is the director
the director of movie Jawan is Otli, wow amazing
now I ask him how did planet earth came into existence
let's wait for its answer
What do you want to ask? It started again because we had ended it, so I will ask it again
How did planet earth came into existence?
and after this you will see
that it will tell you that this is how planet earth came into existence
and this audio
Let's ask AI
so this way you can
make your own bot and publish it
and give it to your users
so that they can use it
you can embed this bot on any website
so that on your existing website
these bots can chat with users
I hope you enjoyed
making this AI chatbot
and you can explore other things on it
now a question you might have is that why are you ending the conversation
I can keep it here again without ending it
and if there is any specific thing that I feel that the user's query has been answered then I will end it
but you explore all these things, I am ending the conversation after a question
so that should actually not concern you
and make such good bots like this
and if you make a good bot, let me know in the description
I would love to interact with your bot
Thank you so much for watching guys!
