How Tomo works

  • Select text or take a screenshot in the app you are already using.
  • Tomo opens with that context attached, ready for your question.
  • Dismiss the window and return to the active app.

Anything you send is handled according to your chosen endpoint's policies.
Local models
Connect Ollama or another local endpoint to keep model traffic on your Mac.

Questions

Is Tomo an "AI agent"?

No. Tomo does not run commands or modify your files. It sends the context you provide to the selected model endpoint and displays the response.

What else do I need to install?

Nothing else for cloud providers: add your API key in Tomo and start chatting. To run models locally, install and start Ollama.
