Build a Chatbot Based on Your Own Documents with ChatGPT | Step-by-Step Guide

With an AI chatbot, you can have a stimulating conversation partner to challenge your ideas and discuss completely new concepts! I’ve been using ChatGPT for some time now — not just to informally converse but also explore some interesting thoughts. Although the novelty factor may diminish after awhile, its potential shouldn’t be underestimated; it’s even capable of generating ‘hallucinations’ that could push us out of our comfort zone with exciting possibilities!

OpenAI’s GPT 3.5 series API is revolutionizing the way we can use AI for productivity! Every industry, from customer support to user research, now has access to a powerful new tool: QA (Question Answering). Not only does this enable businesses and individuals alike to quickly find answers with natural language questions — it also provides an intelligent way of organizing knowledge within your own company or personal data set[1]. The possibilities are endless – how will you apply the latest in advanced machine learning technology?

Different approaches can open up a world of possibility

As a full stack web developer, my days are filled with reading customer feedback and internal documents. But recently I discovered the amazing potential of ChatGPT to help me out in this task! Rather than spending countless hours pouring over data myself trying to find relevant information, ChatGPT has been an incredible assistant for quickly synthesizing what customers need from our products or uncovering related old product docs about current project features. It’s innovative technology that every dev should check out!

When it comes to multi-document question and answer (QA) scenarios, finding accurate, reliable solutions can be a tall order. We could use advanced language models such as GPT to help with this task… but there’s one big issue: fine tuning an existing model is expensive – not only do you pay the cost of training data sets which often have dozens or hundreds of examples – each time the document changes requires another round at that same expense! And even still… no amount of finetuning will let your machine “know” all information contained within those documents; it simply teaches them new skillsets.. Ultimately then, for complex QA tasks like these ones present in multiple docs situations? Fine tuning isn’t necessarily our best bet.

Prompt engineering can be a great way to accomplish accurate text generation using GPT-based methods. By providing the context in the prompts and appending original document content prior, we are able to better equip these models with meaningful information that may help them towards more sophisticated outputs. Yet there is often an issue of scalability as most GPTs have limited attention spans; usually about 4000 tokens or 3000 words at maximum! This presents challenges when dealing with potentially thousands of customer feedback emails backed by hundreds upon hundreds of product documents – it would take significant monetary costs if we wanted to pass all this extra data into our API considering pricing being based on token usage. How do you go around this dilemma?

					I will ask you questions based on the following context:
— Start of Context —


— End of Context—
My question is: “What security features users want to see in the application?”

Is your research project limited by the number of input tokens?

I know mine was! That’s why it felt like a dream come true when I discovered LlamaIndex, an incredibly easy-to-use library that allows you to quickly and accurately search documents for relevant excerpts; all without compromising on any quality. It truly has been such a great help in getting my GPT model the exact contexts needed for generating precise answers – saving me tons of time & energy! [2]

With LlamaIndex and GPT, quickly get intelligent answers to complex questions. It’s the perfect combination of natural language processing (NLP)s and machine learning (ML). In just a few steps you can create an index with your document data – then query it using plain English. Before long, you’ll have contextualized results that are based on all relevant information from those documents. And best of all? You don’t need any prior knowledge! Queries made simple – really truly effortless AI-based conversation has arrived!

LlamaIndex is revolutionizing the way we interact with original document data. By vectorizing documents and indexing similarity-based queries, this innovative platform provides a more efficient approach to finding relevant insights from large datasets. Not only that, but it also supplies GPT (Generative Pre-trained Transformer) with pertinent context so you can obtain accurate answers quickly!

Hands on!!!

Having the right tools can make any project a success! Before you get started, it’s important to install some necessary libraries. No need for coding wizardry – just run this simple command in your terminal or Google Colab notebook and you’ll have LlamaIndex and OpenAI at your disposal. Now that’s what we call tech-savviness!

					$ pip install llama-index
$ pip install openai

Now it’s time to get creative! We’ll be importing OpenAI libraries into our Python scripts and setting up your API key – unlocking a whole world of possibilities. Here’s how you can make the most use out of this powerful toolset, letting yourself explore more advanced projects with ease! 

 Create a new file:

					# Import necessary packages
from llama_index import GPTSimpleVectorIndex, Document, SimpleDirectoryReader
import os

os.environ['OPENAI_API_KEY'] = 'sk-YOUR-API-KEY'
Now lets construct the index and save it!

Once you have all the necessary libraries set up and imported, get ready to construct a powerful index of your document! With LllamaIndex’s SimpleDirectoryReader method, it only takes one click for you to upload what used to be overwhelming amounts of information. Or if strings are more your style, that option is always on the table as well.

					# Loading from a directory
documents = SimpleDirectoryReader('your_directory').load_data()

# Loading from strings, assuming you saved your data to strings text1, text2, ...
text_list = [text1, text2, ...]
documents = [Document(t) for t in text_list]

Looking for an easy way to connect your data? LlamaIndex has you covered! With their variety of connectors, like Notion, Asana, Google Drive and Obsidian – just to name a few – linking up all the important info in your workflow is easier than ever. Check out now to explore what they have on offer!

With the documents loaded, we can get to work on building up our index with ease!

					# Construct a simple vector index
index = GPTSimpleVectorIndex(documents)

If you want to be able to access your index at any time, loading and saving it is key. Fortunately there are a variety of easy methods available for doing so!

					# Save your index to a index.json file
# Load the index from your saved index.json file
index = GPTSimpleVectorIndex.load_from_disk('index.json')
Querying the index is simple!

With some clever querying, you can unlock the secrets of an index! Using specific questions to explore and understand a dataset is one way to find answers that may have been hidden in plain sight. Query away- who knows what kind of insights await?

					# Querying the index
response = index.query("What security features users want to see in the application?")

Have you ever wanted a quick and accurate answer to your inquiries? Well that’s now possible with LlamaIndex. By simply typing in the prompt of your question, this innovative search engine can find relevant chunks within its index – then later pass these along with the initial input through GPT to provide a speedy response! Goodbye tedious online searches– hello hassle-free answers!

With LlamaIndex, you don’t need to stay in the shallow end of question answering. Dive deep into a sea of possibilities with this powerful open source tool! You can use different LLMs for each task and even update existing indices – so much more than originally anticipated! Learn how it works on their comprehensive documentation at It’s time to explore beyond simple query answers; get ready for an exciting journey through GPT & LlamaIndex today!
