Before you build the app,
forge the spec.
Spec Forge interviews founders with structured product questions, challenges vague assumptions, and turns early ideas into a clear brief your designer, developer or product team can actually use.
"I want an app that helps coaches manage clients and maybe uses AI… not sure about payments yet."
- — What kind of coach? Fitness, life, business?
- — Who pays — coach or client?
- — What workflow is painful today?
- — What must exist in v1?
- primary user
- Independent fitness coach
- core workflow
- Onboard → Programme → Review
- risks
- AI scope unclear · payments TBD
- mvp cut
- Client list · session log · weekly review
Three stages. One artefact.
Spec Forge is not a chatbot, not a code generator. It is a structured product interview that compresses chaos into a build-ready document.
Structured intake
12 stages — problem, users, journey, MVP cut, data, platform, auth, integrations, risks, metrics. One focused question at a time.
Intelligent pushback
Vague answers get challenged. Contradictions are surfaced. Assumptions and risks are tracked as first-class artefacts.
Build-ready brief
Submit when ready. A reviewer receives the structured brief as Markdown and JSON, scoped to a realistic MVP.
What lands in the brief.
A structured document, not a finished app. No code, no design files, no promises about delivery.
