You've got an idea rattling around. Maybe you've talked it through with ChatGPT, jotted notes in a dozen places, or explained it differently to everyone who asks. Weeks of circling the same questions: who's this for? What's the real problem? How would I even build this?
Preludio compresses that into a single conversation. Describe your idea, answer the right questions, and walk away with structured docs you can actually point to. Your plan evolves as you talk - you never have to manually create or organize anything.
Describe your idea like you're explaining it to a smart friend. No templates, no forms.
Preludio asks the right questions, challenges assumptions, and captures decisions as structured docs.
Your docs evolve with the conversation. Export anytime, or keep going - they're yours.
Limited spots. Once they're gone, they're gone.
Get in first. Stay forever.
Reserve your spot.
For getting started.
For power users.

Preludio was planned using Preludio before Preludio existed.
Over two evenings in a single Claude CLI session, I went from a rough idea to 17 finalized planning docs: business model, pricing, architecture, launch plan, even this landing page copy. The conversation was the planning process.
That's when I knew the tool worked. I'm looking for 20 founders who want to help shape what comes next.

Preludio is a conversational planning tool. You describe your idea, and Preludio helps you turn it into structured planning documents - business model, target users, technical architecture, whatever your project needs. Documents are markdown and yours to keep.
Founders get access immediately - the product is ready. Beta depositors get priority access when we open up wider. Entrepreneur and Pro subscriptions launch after the beta period.
Both plans include Deep Think AI planning. Pro adds unlimited projects (vs 10), git repository access for local editing, and PDF export. If you're planning multiple projects or want to work in your own editor, go Pro.
Beta deposits are fully refundable until beta launches. Founder tier is non-refundable - it's a bet on what we're building. Subscription plans will have a 14-day money-back guarantee.
Your questions, feedback, and ideas go straight to my inbox - and I reply. No support tickets, no waiting. This is exclusive to Founder tier members.
Yes. Your documents are yours - export anytime, delete anytime. No lock-in.
