BuildBrief turns a two-sentence app idea into a build-ready plan in about 15 minutes. Four prompts, run in any AI chat tool you already use: an honest idea validator, a screen blueprint, a ready-to-paste build prompt for Lovable/Bolt/Cursor, and a 48-hour launch checklist. Each prompt auto-fills from the last one, nothing gets retyped. One self-contained HTML file. No account, no software to install.
Hey Product Hunt. I kept starting app ideas and abandoning them by day two, not because the idea was bad, because I never validated or scoped it first. Built this for myself: four prompts, each one auto-filling from your last answer, so you go from idea to a real build prompt without retyping context five times. Would love feedback, especially from anyone who's tried vibe-coding an app and stalled out.
