The short version.

Duet is a thinking layer for product work. It gives early ideas somewhere to breathe—then helps you turn the ones that matter into a clear next step, a living spec, or a decision worth sharing. The building still happens in your own tools; Duet makes sure the right thing reaches them.

Neither, exactly. Most tools demand an answer too early: what is this, who owns it, when is it due? Duet keeps the answer open until the thinking is ready. It owns the space between an idea and the moment it's ready to build.

Founders and small product teams who do the shaping work—deciding what to build and why—before handing off to engineering. If your days move between half-formed thoughts, specs, and decisions, Duet is built for you.

A single place to capture a thought, tension, or half-formed direction without labels or per-note decisions. Capture happens before classification, so the half-formed thought is protected instead of lost in a meeting note or chat thread.

It arrives in your Build Inbox, where you decide whether it has enough shape to move forward. Triaging is a deliberate translation: make a task, start a spec, park it, or send it back for more thought.

Track 1 (Explore) is where ideas are captured and refined. Track 2 (Commit) is where they become concrete work—tasks, specs, and decisions. The separation keeps raw thinking and committed work from blurring together.

Yes. Build is personal by default: your own Inbox, decisions, and next moves. The Free and Pro plans are designed for individual use.

Project is where the team keeps the shared product narrative current—a shared roadmap, a decision log with reasoning attached, and a review queue for proposals that need the group. Not every raw thought gets published, only the ones that matter.

Personal is free while in early access. Pro is $20/month (or $200/year) for unlimited projects and personal project memory. Team is $250/month for up to 10 people with shared roadmap, wiki, and review queue.

Join the waitlist from the pricing page or create an account. We open capacity in waves and send an invite when your turn comes. No card is required to start.

Your ideas, specs, and decisions are yours. In the live product they're stored in your workspace and exportable. The current prototype runs entirely in your browser against sample data.
