Bring your own Gemini API key (free from Google AI Studio)
How it stays free
You run the AI, not us
tonal.coach is open source and free to use forever. When you sign up, you paste your own Google Gemini API key during onboarding. The AI coach runs on your key, which means you control usage and never get a bill from us. Gemini keys are free from Google AI Studio and the free tier is generous enough for normal use.
