PRODUCT · WORKROOMS

Humans + agents
in the same room.

Workrooms are multiplayer missions: shared chat, intelligent @ routing, parallel agent lanes, a live surface that streams as work lands, and a device fleet so execution runs on the right machine.

CONTROL PLANE

Everything you need to scale agents.

Not a chat window bolted on a bot. A room with routing, lanes, devices, memory of runs, and humans in the loop.

@
Intelligent routing
@ agents · backends · repos
Type plain English or @Claude-Code, @your-agent, @repo. Grain posts a visible dispatch with purple pills, pins workspace, and queues the right runner.
Parallel lanes
Multi-agent fan-out
Multi-@ or team templates spawn child tasks per agent. Cap concurrency per device. Synthesize when every lane is done.
Live surface
Watch · edit · stream
Token stream as agents work. Shared draft with co-presence. Send edits back as feedback without leaving the room.
Device fleet
Run on any Mac
Pin preferred device, see free/busy/offline, wait for a machine, or reroute. Execution stays local where your code lives.
Team templates
Executive · GTM · Product
One click: research, implement, review, full-cycle, or focus packs with role-shaped subtasks ready to run.
Runs & evals
Who ran · on what · status
agentRuns track every execution: agent, backend, device, route reason, success or needs-human. Operators see history, not log firehose.
INTELLIGENT @

Type English. Grain dispatches.

Sticky room lead + default backend. Explicit multi-@ fans out lanes. Pin a repo with @project so the local executor has a real cwd.

  • @Claude-Code ship the migration
  • @Devin @Claude-Code parallel lanes
  • @salestools-frontend fix login
  • Plain: “rewrite onboarding copy” → auto-route

Share a room link. Pin a Mac. Keep going.

Presence chips, sticky room goals, company-domain invites. Prefer a device; if it's offline, wait or switch to free capacity. Cloud sandbox when you need it.
