Decomposer

Decomposer is an AI project planner aimed at solopreneurs and people building side projects. You describe what you want to build, and it generates a structured plan with tasks, dependencies, risk flags, and clear labels for who should do each step: you, AI, or an expert.

It is designed to move beyond one-off brainstorming. After the plan is created, you can use a Focus View to work through tasks in sequence, capture outputs from completed steps, and let downstream tasks update as your decisions change. Setup appears simple: create a free account, then start a plan from the web app. The product also surfaces AI tool matches for individual tasks, based on the agentic.ai directory.

Decomposer is most useful if you want planning support that stays attached to execution instead of a static checklist. The strongest part of the product is its task dependency model and the way it distinguishes between work you can do yourself, work that AI can help with, and work that still needs a real expert. That makes it more practical than a generic chatbot for project planning.

It is still not a fully autonomous agent. The user remains in control, and AI tasks are presented as copy-ready prompts rather than completed actions. The site says data is private by default, but the details of that privacy model are not explained in the provided content. Pricing is partially clear: there is a free tier with up to 3 plan generations and a Pro plan for $10/month, but deeper technical details such as the AI models used are not publicly specified in the captured content.
