Think without breaking your flow.
Capture the question, contradiction, or possibility before it disappears into a meeting note or chat thread.
The thinking layer before you build
Decide what to build before you make it.
Duet gives your 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 just makes sure the right thing reaches them.

Why Duet
Not another task manager with an idea box.
Most systems 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.
Give ideas structure when they earn it.
Triaging is a deliberate translation: make a task, start a spec, park it, or send it back for more thought.
Keep the why beside the work.
Roadmap, decisions, and wiki preserve the context your future self—and your collaborators—need.
How it works
A loop for the work before the work.
Duet owns the space between an idea and the moment it's ready to build. The thinking, specs, and decisions live here; the shipping happens in the tools you already use.
Capture
Write a thought in the Idea field. No labels or per-note decisions required.
Understand
It arrives in Inbox, where you can see whether it has enough shape to move forward.
Refine
When it needs more clarity, reopen it as a focused question—or switch into a short brainstorm.
Commit
Turn the outcome into a task, spec, decision, or a deliberately parked thread—then hand it to whatever you build in.
Built for personal focus and shared direction
Work alone. Align together.
Build remains personal: your own Inbox, decisions, and next moves. Project is where the team keeps the shared product narrative current.
Start with the thought you have
Make space for a better next move.
Duet System is for the part of product work that usually happens between documents, tools, and conversations.
