Code
Turn a product idea into an implementation blueprint — user stories, stack proposal, folder layout, and first-mile tickets (not hallucinated repo URLs).
Cheaper than rewriting the wrong repo layout week three.
Feed a crisp vision, pick platform and stack bias, name non-goals so the model does not gold-plate social graphs you never wanted. You get user stories with acceptance checks, a boring-first stack table, a folder-layout sketch, a first-pass data model, and a milestone map sized to your MVP horizon — plus a boxed "do not hallucinate" list of unknowns the model needs from you. The output is structured to drive real discovery conversations, not to replace them.
Six concrete uses that beat "thinking about it more."
Eight sections shaped for downstream execution.
One paragraph
Tight problem framing and primary persona — the basis for every story below.
5-12 with criteria
Acceptance criteria bullets per story so engineers can estimate without follow-up.
Layer → tech → why
Boring-first defaults with explicit rationale, not flavor-of-the-month framework picks.
ASCII sketch
Folder structure your IDE agent can scaffold against without asking clarifying questions.
Tech + product
Top risks for both axes so the team has a shared mental model of what could go wrong.
Honest gaps
Explicit list of facts the model needs from you before turning the plan into code.
Planning moments where the cost of being wrong is high.
Most rewrite fires start as planning fires.
The expensive bugs are not in the code — they are in the gap between what was specified, what was built, and what the customer actually wanted. Structured blueprints make those gaps explicit. User stories with acceptance criteria force decisions before code commits. Stack rationale prevents the "why is everything in Rust?" conversation six months later. The unknowns box exposes assumptions you can resolve cheaply now instead of expensively later. Use the blueprint as a forcing function for honest conversation, not a substitute for it.
Habits that compound across your roadmap.
No — this tool outputs a planning blueprint. Use your IDE agent (Cursor, Copilot, etc.) for implementation, with the user stories from this output as your epics.
It is instructed not to. The unknowns box surfaces gaps explicitly — if HIPAA, SOC2, or specific vendor relationships matter, you supply them in the vision; the model never invents them.
Yes — describe the current state in the vision field. The blueprint includes a phased migration plan with risk callouts when you frame it as a rewrite or evolution.
Only what you paste. For regulated or specialized domains (healthcare, fintech, gaming), include domain context in the vision so personas and risks are honest.
Sized to your MVP scope — tight is two-week realistic, medium is six-week realistic for a small team. Adjust based on your actual velocity.
Default reasoning-capable models for product planning quality. Switch to deeper models for complex multi-team initiatives or large architectural rewrites.
Yes — it is structured for that exact use. Founders share it with co-founders, agencies share with clients, and engineering leads share with product partners.
Direction is a moat.
Most rewrite fires are planning fires. Burn the blueprint once, treat the unknowns box as homework, then ship. The teams that move fastest are the ones who spent an hour aligning before they spent a quarter coding.
