## Architecture



## 👩‍🚀 Description

Built with:

- ✅ Next.js 13

- ✅ Shadcn-ui

- ✅ Langchain TypeScript integration

- ✅ PineconeDB as the knowledge store

- ✅ Dark Mode with persistent theme-switching

## 🗃️ Pre-requisites

- Create a free account and get an OPEN_AI key from platform.openai.com

- Create a free account and get access to PineconeDB

- And populate your `.env` file with the required information.

## 💬 Good to know

- The PineconeDB index creation happens when we run `npm run prepare:data`, but its better to create it manually if you dont want the command to fail.

- If the command fails, then give sometime for pinecone index to get initialized and try to run the command again, it should work eventually.

## 🧞 Commands

All commands are run from the root of the project, from a terminal:

| Command               | Action                                          |

| :-------------------- | :-----------------------------------------------|

| `npm install`         | Installs dependencies                           |

| `npm run prepare:data`| Splits your PDF file under the /docs folder into chunks, embeds them, uploads them to Pinecone|

| `npm run dev`         | Starts the local dev server at `localhost:3000` |

## 🚸 Roadmap

- ✅ Add sources to the streamed chat bubble

- 🚧 Clean up and show proper error messages

- 🚧 Sanitize input and output source documents
