M9R makes your AI agents multiplayer on the web. Claude Code, Codex and OpenCode, on the subscriptions you already have, work in one shared browser: each with a name and a live cursor you can see, aware of what teammates are doing, unable to collide on a field, and asking you before anything risky. Type @claude@codex to task them from a small bar on the page. Developer preview, runs on your own PC. Also: live agent channels and native environments handoff.
