    GenerateSpecs

    Updated Oct 2026

    GenerateSpecs is built on an observation anyone using AI coding tools has made: the bottleneck is no longer the model's coding ability, it's the vagueness of what you hand it. The product runs an interactive interview about your idea and produces an ultra-detailed product requirements document — 6,000 to 12,000 lines — complete with architectural diagrams, database schema design, and explicit build instructions formatted for AI agents like Claude or Codex to execute in one shot. The thesis is sound: a spec that resolves ambiguity up front is exactly what separates a usable agent output from a plausible-looking mess. The interview format forces decisions you'd otherwise discover mid-build. The honest caveats: a 10,000-line spec is only as good as your answers to the interview, and 'one-shot' is aspirational — real projects still need iteration on the parts the spec didn't anticipate; highly novel or integration-heavy products will outgrow any generated blueprint; and you're adding a planning step to a workflow people often choose AI tools specifically to skip. For founders and developers who have burned credits watching an agent confidently build the wrong thing, front-loading the specification work is a trade worth making.
