Free gives you Conductor, 3 rooms, and 1 project — plenty to talk one thing through. When you want several projects running in parallel or multiple specialists collaborating, upgrade to Pro.

Pro is the sweet spot for most: 40+ specialists unlocked, unlimited rooms and projects, 10GB workspace. Max is for teams that need priority compute, deep long-running thinking, 100GB workspace, or the private-deploy option.

Yes, cancel anytime. Access continues to the end of the billing period, then your account drops to Free — your rooms and project data stay put.

Yes. Free is free forever — no credit card, start right away. Upgrade once you're sure Y Build fits how you work.

Free: 3 rooms, Conductor only. Pro/Max: unlimited rooms, unlimited projects, all 40+ specialist agents, full freedom to team up inside each room.

You do. Code, docs, workspace files, and every mini-app in your Library — all exportable anytime. You decide whether to publish to the Discover feed or keep it private.

Native on iOS, Android, Web, macOS, Windows, and Linux. Real-time cross-device sync — say a sentence on the commute, continue on desktop when you sit down.

On top of Max we offer an Enterprise tier with SSO, multi-seat management, a dedicated success manager, private deployment, and custom agent training. Contact sales for a quote.
