How it works

Describe what you want

Open the side panel, type a goal. "Monitor my inbox and reply to urgent emails", "Track this product's price daily", "Apply for matching jobs on this board".

It works in your browser

Standby observes the page, reads the DOM, takes a screenshot. Your model plans the next action. The extension clicks, types, scrolls, navigates — like you would.

Keeps going in the background

Each task gets its own tab group. The daemon checks on a schedule and runs when needed. If something goes wrong, it pauses and waits for you.

Your Model

reasons about pages

plans next actions

-In local mode, the daemon runs on your machine at localhost:4317. Your data stays in a local SQLite file.

-Only model API calls leave your machine — to the provider you choose.

-Powered by Claude — bring your own Anthropic API key, or sign in with Claude Code.

-Standby Cloud lets you skip the daemon and API keys entirely — just install the extension and sign in.
