Meet Grass. Your agents work. You check in. Fire a task. Pocket your phone. Come back to progress. Grass RUNS Tasks on Grass Computer or your own machine - while your laptop is closed, while you're in a meeting, or while you're away from your desk. No terminal to watch. No session to babysit. Grass MOVES Send a coding session to Grass and keep the thread moving on a remote instance โ€” conversation, context, and all. Your phone buzzes when it's live. Grass ALERTS The moment your agent needs a decision or finishes the job. You don't push for status. Status finds you. Permission needed? Approve from your pocket. Grass CLEARS Every permission prompt from every thread in one tab. Read the diff. Yes or no. Keep multiple threads running in ask-mode without watching all of them. Grass STARTS A new thread in two taps. Quick chat button โ†’ bottom sheet โ†’ task running. No app switching. No losing your place. The idea fires โ€” the experiment actually runs. Grass SHOWS Which thread is which. Running, completed, waiting โ€” all visible on the home screen the moment you open the app. Switch machines with one tap. Name them whatever you want. Your harness. Your code. Our compute. Designed for AI coding agent workflows, including supported integrations with Claude Code and OpenCode.
