Your AI. Your key.

Bring your own AI — pennies per trip.

Let's Go runs on your AI key from Google Gemini, OpenAI, or Claude. No subscription on top of the app. Most travelers spend pennies per trip — and Gemini has a free tier, so you can start without a credit card.

  • 60-second setup. Open the provider, click “Create key”, paste it in Settings. We test it for you.
  • Cheap by design. Gemini free tier covers most travelers. OpenAI gpt-4o-mini and Claude Haiku run a few cents per trip.
  • Private. Your key lives on your device and syncs only to your own account — never to us, never to other users.
  • Switch anytime. Change provider, swap models, or remove your key in one tap.
