Duet

How Duet works

Open a room, share one link, and let your whole team think together inside a single AI context. Every message merges, every response streams to everyone.

Streamed to all

Based on the team's input, I recommend: (1) Keep auth migration in scope, (2) Defer export polish to next cycle...

Open a room

Create a new session in one click. Pick a name, choose your AI model, and you have a live room ready for collaboration. Each room holds its own conversation thread that persists across the session.

Share one link

Every room gets a unique invite URL. Send it to your team over Slack, email, or paste it in a doc. Anyone with the link joins instantly - no sign-up friction, no waiting rooms.

The room thinks

Everyone types into the same shared context. The AI sees all contributions and streams one unified response back to every participant simultaneously. Tokens arrive as they are generated.

Under the hood

Built on WebSockets, not polling

Every connection is a persistent, bidirectional channel. Messages flow in, tokens stream out - no request-response overhead.

Real-time streaming

Tokens fan out to every connected client the instant they arrive from the model. No buffering, no polling.

Shared context

All messages from every participant merge into a single conversation thread the AI reads in full.

Multi-provider

Switch between Claude, Gemini, and OpenRouter models without leaving the room.

BYOK

Bring your own API keys. Your credentials stay on your machine and never touch our servers.
