Built for founders, visionaries and creators. Technical or not.

You bring the idea. We make it buildable.

Go from a rough idea to a build-ready spec in one session, not weeks of back-and-forth. Vibemaster asks the right questions and writes the spec your AI tool builds from.

Questions? We have answers.

Do I need to know how to code to use Vibemaster?

No. Think of Vibemaster as a technical co-founder who structures your idea. You describe what you want to build — we turn it into a buildable product spec that AI tools can follow directly.

Does Vibemaster build my product for me?

No. Vibemaster writes the "recipe" — a clear product spec that AI can follow. Building happens in AI tools like Lovable, Claude Code, Cursor, etc. The difference is they now know exactly what to build.

Is Vibemaster an AI PRD generator?

Yes. Vibemaster is an AI PRD generator built for AI coding tools. Instead of a single form, it interviews you, suggests answers when you get stuck and writes the code prompt your AI tool builds from, the architecture as a flowchart, a business plan and a week-by-week implementation roadmap, ready for Lovable, Cursor, Bolt or Claude Code.

How does Vibemaster differ from using ChatGPT or Claude?

ChatGPT and Claude give you answers. Vibemaster gives you a buildable product specification. Instead of a conversation, you get a structured plan with features, user flows, data model, and instructions that AI can build from.

What exactly do I get?

You choose what to generate: a code prompt your AI tool builds from (with the architecture, setup files and build order), the architecture as a flowchart, a business plan with a Business Model Canvas, a week-by-week implementation roadmap, and an analysis with stats. Paste the code prompt straight into Lovable, Bolt, Cursor or Claude.

Is my data secure and do you comply with EU regulations?

Yes. Vibemaster and its database run in the EU (Scalingo, Paris) and personal data is handled under GDPR. Choose Mistral, a European AI model, and your ideas are processed in Europe too. Some providers are not EU-based: the default AI model Gemini (Google), payments (Stripe), login (Supabase) and error reports (Sentry). When data is processed outside the EU, EU standard contractual clauses apply. You own the output you generate, and anything we use to improve the service is anonymised first.

Can I cancel anytime?

Yes. Professional is billed monthly or yearly and you can cancel anytime. Receipts and invoices come by email. The free plan has no time limit, so you can stay on it as long as you like.
