Vercel AI Chatbot

This is a clone of Vercel's AI Chatbot at commit 7d8e713.

Running locally

Requirements

• Docker

1. Clone the Repo

In a terminal,

git clone https://github.com/Sindri-Labs/vercel-ai-chatbot.git
cd vercel-ai-chatbot

2. Setup (Run with Sindri)

Configure your environment variable file that will be used with Docker Compose

cp .env.example.sindri .env

Then, edit your new .env file. Fill out the OPENAI_API_KEY variable with your Sindri API Key. A Sindri API Key can be generated by first creating a Sindri account then visiting the API Keys page.

3. Run

Build and run the application (building will take several minutes)

docker compose --env-file .env up --build

You will know it is ready when you see logs similar to

vercel-ai-chatbot-frontend-1  |  ✓ Starting...
vercel-ai-chatbot-frontend-1  |  ✓ Ready in 542ms

4. Visit the Site and Start Chatting!

Visit http://localhost:3000 and start chatting as a guest user. Chat history will not be saved between sessions.

Notes:

• All chats are automatically encrypted with Sindri's Trusted Execution Environment (TEE)! The console logs for the evllmp container show encrypted/decrypted chats.
• Sindri is still in development. File uploads and web searches are still in development and currently do not work.

5 (Optional). Create an Account and Log in to Save your Chat History

Visit http://localhost:3000/register and create an account.

You can also visit the Account menu in the bottom of the left sidebar. Here you can create accounts and log into existing accounts.

6. Stop

To bring it all down, run:

docker compose down

You can bring it up again with docker compose --env-file .env up. This will skip the building phase and existing accounts and their chat histories will be restored.
