证据

TouchGrass is a web app that uses AI to turn screen time into a reason to go outside.

来源

The app tracks both your current session time and the time spent completing the challenge, encouraging you to actually step away from the screen and interact with the world around you.

来源

TouchGrass is powered strictly and exclusively by Google's open-weight Gemma 4 models via the @google/genai SDK

来源

The app uses a server-side API route to keep the AI API key out of the client, while session and timer state are persisted locally so refreshing the page doesn't reset an active challenge.
