About

What It Is

Decomposer is a web-based planning tool that turns broad ideas into step-by-step execution plans. It is aimed at individuals, founders, and small teams who are starting projects that feel too large or ambiguous to tackle in a single chat prompt.

According to the site, you begin by describing a goal, brief, or messy notes, and the app generates an organized plan with actionable steps. It also includes copy-ready prompts for external AI tools like ChatGPT or Claude, plus options to share plans and export them.

What to Know

Decomposer is useful when you need structure more than conversation. It does not appear to run tasks on your behalf; instead, it helps you decide what to do yourself, what to hand to AI, and when to involve an expert. That makes it more of a planning copilot than a fully autonomous agent.

The product is described as private by default, but the site does not provide detailed privacy or model documentation in the visible content. Pricing is clear: there is a free account with a generation limit and a paid Pro tier for unlimited plan generations. If you want an agent that directly executes workflows, this is probably not the right fit.
