Free is enough for one website. Here's when to pay.
The engine is deterministic. The same answers always return the same bytes, so a spec you generate on the Free plan is identical to a Pro one — you are not paying for a better prompt. You pay to keep generating, and to keep every spec and its export pack in one place.

What the paid plan actually buys
Not a smarter output. Volume, and a memory of your projects.
Stay on Free if…
You are building one site. Answer the questionnaire, read the 14-section spec,
download the 8-file pack (CLAUDE.md, AGENTS.md, .cursorrules,
.windsurfrules, copilot-instructions, README + zip), and hand it to your
builder. That is the whole product. You never have to pay to finish one project.
Go Pro if…
You ship more than one. An agency running five client builds keeps five living specs in one dashboard instead of five text files scattered across downloads. Pro removes the 2-spec limit and saves every spec and its export pack so you can reopen, tweak and re-download them months later.
Why this beats a one-shot prompt
Most prompt tools hand you one paste-once block aimed at a single editor. The moment the AI drifts
mid-build, that prompt is gone. Here the output is a spec plus governance files that live in
the repo — CLAUDE.md for Claude Code, .cursorrules for Cursor,
.windsurfrules for Windsurf, copilot-instructions for Copilot, a shared
AGENTS.md. They keep every agent on-spec across the whole build, not just the first message.
That pack is in the Free plan too. Paying just keeps a library of them.
Pricing questions
Is the Free plan really enough?
For a single website, yes. You get 2 complete specs, all 7 project types, every one of the 14 sections, and the full export pack with a zip. Generate it, download it, build. Nothing is watermarked or trimmed on Free.
So what does paying change about the output?
Nothing. The engine is deterministic: the same answers produce byte-for-byte the same spec on Free and on Pro. There is no hidden “better” version behind the paywall. Pro lifts the 2-spec cap and keeps a saved, searchable history of every spec you generate.
Monthly $19 or one-time $99 — which?
Lifetime pays for itself after about five months. Take the $19/month Pro plan if you are clearing a short backlog of projects then stopping; take the $99 Lifetime if generating specs is part of how you work. Both remove the free-spec limit.
Can I cancel?
Yes. Cancel the Pro subscription from your account at any time and you keep access until the paid period ends. Lifetime is a single payment through Stripe — there is nothing recurring to cancel.
Do I keep my specs if I stop paying?
The spec text and the export files are yours the second you download them — they sit in your repo, not on our server. Your saved history in the dashboard stays readable; you just can't generate new specs past the free limit.
Which builders does the output work with?
The spec pastes into Claude Code, Cursor, Bolt, v0, Windsurf, Replit and Lovable. The export pack
drops native rules files for Claude (CLAUDE.md), Cursor (.cursorrules),
Windsurf (.windsurfrules) and Copilot (copilot-instructions), plus a
shared AGENTS.md.
Is my payment secure?
Checkout runs on Stripe. Card details go straight to Stripe — we never see or store a card number. You can pay by card or the wallet Stripe offers in your region.
