What it does

Antigravity Link is an extension for Google's Antigravity IDE, built for people who step away from the desk while an AI session is still running. After starting its local server and scanning a QR code, a phone browser shows the active chat as it streams. From the phone you can send messages, stop generation, upload files into the chat, dictate by voice and switch between several Antigravity windows. The mobile page detects the browser language and renders in 16 languages. The extension also runs a local HTTP API protected by a bearer token, and ships an MCP server so other assistants or tools can read chat state, send messages, stop generation, switch windows, click interface elements and read the task, walkthrough and plan documents. Setup needs Antigravity IDE launched with a remote debugging port, and the phone and computer on the same Wi-Fi network. The page says all traffic stays local and that the extension sends nothing to outside services.
