Step 2

Open Terminal and run one command

Terminal is an app already on your Mac. Press Command + Space, type Terminal, hit Enter.

ollama pull gemma4

This downloads your AI brain — about 5GB, like downloading a movie. Takes a few minutes.

Step 3

Start Terrapin

Open Terminal and run these two commands — one in each tab:

npm run agent
npm run serve

Then go to localhost:8080/agent.html and both dots will be green.

Everything runs on your computer. Nothing goes to the cloud. Your data never leaves your machine.

Requires a Mac with 8GB RAM or more. Windows support coming soon.
