Process

How it works

Connect Claude, GPT-4, Gemini — whatever model you trust. Your key, your data, never stored.

One click generates a shareable session URL. Invite your team instantly — no accounts required to join.

Everyone codes, everyone has AI. Multiplayer cursors, live sync, and no merge conflicts to fight later.

Under the hood

Yjs CRDTs

Conflict-free replicated data types keep every cursor, every keystroke perfectly in sync across the globe.

Your model, your key

No vendor lock-in. Plug in any LLM API. Each collaborator can use their own model simultaneously.

Live presence

See where your teammates are, what they're editing, and watch AI completions flow in real-time.

Open your terminal, then

No waitlist. No setup fee. Create a room in seconds and invite your whole team.
