Prompt specification engine

Your idea is fine.
Your prompt is missing 40 answers.

Write one paragraph about what you want to build. PromptForge interviews you on everything the paragraph left out, then compiles a phased build specification you can hand to any AI — and get back something deployable instead of half-finished.

Bring your own AI key, or use a free-tier provider. Keys are encrypted at rest.

“I want a working cleaning services website that has our services and lets people book, sends me WhatsApp alerts, integrated with M-Pesa, SEO optimised, very sleek and mobile responsive with the best fonts and colours, where I can also manage operations.”

  • 01 No service list, so the AI invents one.
  • 02 No M-Pesa mode, so it stubs the payment.
  • 03 No admin roles, so anyone can edit anything.
  • 04 No hosting target, so it ships code that won't run on cPanel.
PromptForge asks all eleven, then writes the spec that answers them.
The process

Four steps, one deployable specification

01

Describe it once

A paragraph is enough. The system reads it, classifies the project type, and works out which of the twelve question modules apply.

02

Answer the interview

Adaptive questions, mostly taps and toggles. Brand, payments, roles, pages, hosting, data, edge cases. Skip anything and it gets flagged, not forgotten.

03

Review the spec

Every answer lands in a structured specification. A completeness gauge shows exactly which decisions are still missing before you generate.

04

Take the prompt

Compiled into build phases with deliverables and acceptance criteria per phase. Copy one phase at a time, or take the whole thing as Markdown.

Coverage

The questions your prompt should have answered

Twelve modules, applied selectively. A booking site never sees the inventory questions; a fintech tool gets the compliance and audit-trail ones instead.

Brand & identity
Logo, colours, type, tone, existing assets
Roles & access
Who signs in, who approves, who can delete
Payments
Gateways, currency, refunds, failure states
Notifications
Channels, triggers, templates, fallbacks
Data & storage
Entities, retention, backups, migrations
Hosting & deploy
cPanel, VPS or local, domains, SSL, cron
SEO & content
Keywords, schema, sitemap, languages
Security
Auth rules, rate limits, uploads, audit log
Experience
Breakpoints, PWA, offline, accessibility
