Set up your AI

Which AI do you build with?

Gemmein works through your AI tool, either on your computer or as a connector in a chat app or browser builder. Pick yours. Each one takes three steps.

Read https://docs.gemmein.com/llms.txt and take my app to its first paying customer.

How do you want to start?

Let your AI set it up

Copy the one prompt that works in any AI coding tool. Paste it into its chat in your app’s folder and answer its questions.

Set it up yourself

Pick your tool and follow its three steps: Claude Code, Cursor, or ChatGPT and Codex.

Pick your tool

Chat apps and browser builders

Claude.ai, ChatGPT, Lovable, Replit, Bolt, v0 and tools like them.

Add Gemmein as a connector

https://api.gemmein.com/mcp
  1. In your AI app, add a custom connector (in some apps it’s called an MCP server) with this URL.
  2. Sign in and approve “Connect your AI app?”.
  3. Ask it to build: Read https://docs.gemmein.com/llms.txt and take my app to its first paying customer.

It builds in Development. Anything on Live waits for your approval.
