Running locally

You will need to use the environment variables defined in .env.example to run Next.js AI Chatbot.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

pnpm install
pnpm dev

Your app template should now be running on localhost:3000.
