Idea to architecture in one pass
Strategy, data model, APIs, and services come out coherent — not a pile of disconnected suggestions.

Wedge & Positioning
Start with solo founders running one-person SaaS — not agencies. The wedge is "launch a billable product this month": narrow enough to win, broad enough to expand.
Monetization
- Free — 3 generations / month to prove value.
- Founder · $29/mo — 200 generations, saved workspace, export.
- Operator · $99/mo — 1,000 generations, team seats, priority models.
Architecture
Next.js App Router with server routes for fast actions and a worker queue for long jobs. Postgres on Supabase with row-level security per tenant. Claude generation behind a metered, server-side endpoint.
Launch Plan (guarded)
- Ship the generator with save and export.
- Add Stripe billing — you approve go-live.
- Open a public template gallery for SEO.
Why it's different
An operating system, not a chatbot
A real website, not just a plan
Generate a studio-grade landing page from your idea — preview it free, then download the clean source and deploy in one click.
You approve every action
Payments, deploys, and external messages are gated behind human approval. Speed never bypasses control.
Export & iterate
Download as Markdown, refine the idea, and keep every version saved in your workspace.
Written like a founding team
Direct, specific, opinionated — strategy, architecture, security, and growth reasoned through on the latest Claude models. No AI slop.

- Worker queuesHeavy jobs moved off the request path
- Postgres with row-level securityEvery row private to its owner by default
Built to scale
Built to grow
The plans AI Ninja generates are built on architecture that grows with you — server routes for fast actions, worker queues for heavy jobs, and Postgres with row-level security. Go from your first user to your thousandth without re-platforming.
Monetization

Questions
Everything you might ask
Is it free to start?
Yes — 3 generations a month, no credit card. Upgrade to Founder or Operator when you need more volume and the full deliverable.
Which model should I pick?
Sonnet 4.6 (the default) is best for most plans. Use Opus 4.8 for complex or enterprise ideas, and Haiku 4.5 for fast first drafts.
Do I own what I generate?
Completely. The ideas you submit and the blueprints you generate are yours to use however you like.
Is my data private?
Every blueprint is private to your account and enforced at the database level. We don't sell your data or train models on it.
How accurate is the plan?
It's a specific, buildable starting point written like a senior founding team would — strategy, architecture, pricing, and a guarded launch plan. Your judgment still matters before you act.
