AI project planner for solopreneurs
Turn your side project into a real plan.
Describe what you're building. Get a dependency-mapped execution plan in about 60 seconds - with honest labels on who does what, a focus mode that shows you what to work on next, and AI tool matches for every step.
How it works
From idea to execution plan in about 2 minutes. Then stay in the loop.
Describe what you're building
Paste your goal. A sentence works. Add files or context if you have them.
Get a structured plan in ~60 seconds
8-14 tasks with dependencies, risk flags, and honest labels: you, AI, or expert. Each AI task comes with a prompt you can paste into ChatGPT or Claude.
Execute one task at a time
Focus View shows you one task with its prerequisites and what it unlocks. Finish a step, and the next ready task appears automatically.
Your plan adapts as you go
Capture outputs from completed tasks and dependent tasks refine automatically. The plan follows your real decisions - not just the assumptions it started with.
Planning is step one. Execution is the loop.
Most planners stop at the list. Decomposer keeps working with you.
Focus on what's ready
Focus View shows one task at a time. You see what's upstream (prerequisites) and what's downstream (what you'll unlock). No scrolling through a 14-task list wondering where to start.
Prerequisites
Set up a one-page site with your value prop and an email capture form.
Completing this unlocks
Capture what you did
When you finish a task, capture the key outputs - the decision you made, the tool you picked, the budget number you landed on. Structured forms, not freetext.
Captured outputs
Downstream tasks refine
Your outputs flow into dependent tasks. If you chose Stripe over PayPal, the payment integration task updates its guidance automatically. The plan follows your actual decisions.

Track real progress
A progress bar and dependency graph show where you are. Tasks are green (done), amber (in progress), or gray (not started). You always know what's blocking what.
Why not just use ChatGPT?
ChatGPT is great at answering questions. But it can't track your progress, adapt to your decisions, or tell you what to work on next.
Your plan remembers
ChatGPT gives you a plan and forgets it. Decomposer tracks status, captures outputs, and refines downstream tasks as you go. Pick up where you left off - tomorrow or next month.
Honest about what AI can't do
Every task says who should do it - you, AI, or a real expert. No pretending the machine can negotiate your lease or review your LLC filing.
Copy-ready prompts for every AI task
Each AI-labeled task comes with a prompt tuned for that specific step. Paste it into ChatGPT, Claude, or whatever you use.
Dependencies you can see
A real dependency graph - not just a list. See which tasks block others, which are ready now, and what's on the critical path.
Matched with the AI tools to do the work
Each task can show curated AI tools that fit it - sourced from the agentic.ai directory. The plan tells you what to do; the tools help you do it.
