ChatPDF with ConvoStack 🤖

Inspired by mayooear's gpt4-pdf-chatbot-langchain repository, we have integrated ConvoStack to create a chatGPT playground for multiple Large PDF files.

Amazingly, we achieved the same outcome with a much more concise codebase.

Development

1. Run npm install to install all necessary dependencies.

2. Set up your .env file

• Copy .env.example into .env Your .env file should look like this:

OPENAI_API_KEY=

PINECONE_API_KEY=
PINECONE_ENVIRONMENT=

PINECONE_INDEX_NAME=

• Visit openai to retrieve API keys and insert into your .env file.
• Visit pinecone to create and retrieve your API keys, and also retrieve your environment and index name from the dashboard.

3. In the config folder, replace the PINECONE_NAME_SPACE with a namespace where you'd like to store your embeddings on Pinecone when you run npm run ingest. This namespace will later be used for queries and retrieval.

Convert your PDF files to embeddings

This repo can load multiple PDF files

1. Create a docs folder. Inside docs folder, add your pdf files or folders that contain pdf files.

2. Run the script npm run ingest to 'ingest' and embed your docs.

3. Check Pinecone dashboard to verify your namespace and vectors have been added.

4. In src/index.ts, change the templates.qaPrompt for your own usecase. Change modelName in new OpenAI to gpt-4, if you have access to gpt-4 api. Please verify outside this repo that you have access to gpt-4 api, otherwise the application will not work.

Run the app

Once you've verified that the embeddings and content have been successfully added to your Pinecone, you can run the app npm run dev to launch the ConvoStack chatbot playground.
