PromptForge
Turn an idea into a build plan you can ship
Describe your software idea. Get a production-ready AI development prompt, a step-by-step dev plan, and an architecture overview, tailored to your tools, technical level, budget, and compliance needs.
Common scoping mistakes PromptForge catches before you start
Generic AI assistants will happily produce a plan for any of these. You find out it doesn't work mid-build. PromptForge surfaces the conflict and the fix the moment your answers cross.
- Flag and resolve
£0 budget + paid payment processor
Stripe is free to integrate but takes a per-transaction cut; some processors (Paddle, Lemon Squeezy) handle VAT for you for an extra ~5%. We surface the trade-offs and the free-tier alternatives so you pick with eyes open.
- Flag and resolve
SQLite + 10,000 users
Single-writer locking falls over at scale. We recommend Supabase Postgres on the free tier and write the migration path into the plan, not a footnote you'll miss in week three.
- Hard mismatch
iOS native build on Windows
Xcode requires macOS. That's an Apple constraint, not ours. We surface the cloud-Mac alternatives (MacStadium, EAS Build) before Phase 0, not after you've installed Android Studio.
- Flag and resolve
Card payments + non-EU hosting
Card data carries residency rules. We surface the compliance gap and recommend EU-hosted infra + Stripe-managed elements so card details never touch your servers.
What makes PromptForge different
- Recommendation based on your answers. Your budget, scale target, compliance requirements, and chosen AI tool all feed a rules engine that recommends the right stack for your specific situation, not a generic starting point.
- Conflicts surfaced, not silently shipped. When your answers cross, like iOS native on Windows or card payments without an EU hosting region, PromptForge names the conflict and the resolution path before you waste a weekend on the wrong build.
- Structured output, every time. Every plan includes Phase 0, Daily Workflow, Troubleshooting, and Launch Checklist. A validator hard-fails if any required section is missing.
- Format tailored to your AI tool. Claude Code gets CLAUDE.md + TASKS.md. Cursor gets workspace rules. Conversational tools get a single structured prompt. Same plan, the right format for how you actually build.
- Pinned library versions. Tell us “Next 15.1.3, Python 3.12” and the generated prompt instructs your AI never to drift to whatever it last saw in training data.
- Edit one answer, see what changed. Flip £0 to £20/mo. The engine re-recommends database, hosting, and payments instantly and shows what shifted. No restarting from scratch.
