For product managers

Prototype it instead of speccing it.

A spec describes the thing; a prototype settles the argument. Turn the recurring writing into one-click apps — and if you're comfortable in a repo, put a fleet of agents on the prototype yourself.

Why it’s for you

  • The meeting becomes the actions

    Meeting Notes → Actions is a built-in starter. So is TL;DR Summarizer. The parts of the week that are reformatting rather than thinking become a form you fill in.

  • Prototype the tool, not the spec

    Describe the internal tool you'd otherwise write a ticket for — a feedback log, a request tracker — and PromptDeck builds a working version that keeps its data. Export it as a standalone file that opens in anyone's browser, and the argument settles itself.

  • If you're technical, build it yourself

    CodonTerminal runs up to ten AI coding agents in your own repo, each on its own task. It's a developer's tool — it needs Claude Code and a real project — but if that's you, the prototype stops waiting on someone else's sprint.

  • No workspace, no seats

    Both are desktop apps, bought once. Your documents and your repo go to the model provider you choose and never touch our servers.
