Stop building on vibes. Start building on architecture.
prd.c1v.ai generates engineering-ready specs from your product idea — data schemas, APIs, infrastructure — so Cursor and Claude Code build it right the first time. No drift. No rework. No starting over.
Start your product requirements
Define the structure, decisions, and tradeoffs before you write code.
What are you building?
Describe your product vision. What problem does it solve? Who are the users?
You already know the problem. Your AI coding agent doesn't.
Fix one thing, break four others.
You describe the bug. Claude rewrites a function. Three other features stop working. You spend the next hour hunting for what broke — and the fix creates two new issues.
You got to 70% fast. Then you got stuck.
The first 70% felt like magic. Then integration hit. Auth broke the payments. Payments broke the dashboard. Every layer depended on decisions that were never made.
You deleted everything and started over.
Wrong schema from day one. Every fix created two new problems. You spent more time debugging than building — until you gave up and hit reset.
Build
The architecture layer between your idea and your code.
Chat about your product idea. Get engineering-ready specs.
From concept to specs in minutes
Describe your idea in plain English. The AI runs you through actors, use cases, system boundaries, and data models. Out comes professional-grade specifications your developers can build from immediately.
Replaces weeks of architecture meetings and Google Docs PRDs nobody reads.
Custom MCP + 17 specialized agents
Product manager, QA engineer, UX specialist, backend architect, database designer — 17 agents collaborate on your spec. Then export a custom MCP server so your IDE understands the full architecture.
Replaces manually writing CLAUDE.md and .cursorrules by hand.
Anti-drift architecture
10 hard validation gates catch missing actors, orphan use cases, and hallucinated endpoints before they reach your codebase. Persistent memory means your AI never forgets what it already decided.
Replaces the endless "fix one thing, break four others" cycle.
How it works
Three steps. From idea to architecture.
Describe your product idea
Type your idea in plain English. No templates, no forms — just tell the AI what you want to build and who it is for.
AI generates your full spec
17 specialized agents — PM, backend, DB, QA, UX — collaborate to produce actors, use cases, data schemas, API contracts, and infrastructure. 10 validation gates ensure nothing is missing.
Export to Claude Code or Cursor. Build.
One click exports CLAUDE.md, .cursorrules, SKILL.md, and a custom MCP server. Your AI coding agent now understands the full architecture. Build without drift.
Built right
Real builders share what works
“The specs were already there. We built against something real instead of guessing.”
Maya Rodriguez
CTO, Momentum
“Three weeks of architecture meetings became one conversation with the AI. We shipped faster.”
James Park
Founder, Nexus
“The API contracts were exact. Our frontend and backend aligned on the first try.”
Marcus Webb
Lead Developer, Sync
“We had a blueprint before we wrote a line of code. Everything else was just execution.”
Elena Vasquez
Technical Lead, Build
“We stopped arguing about architecture and started shipping. The specs were there, waiting. Everything else followed.”
Alex Chen
Founder, Velocity Labs
“Our developers stopped asking questions and started building. The specs were complete.”
David Chen
Engineering Manager, Scale
“No more arguing about data models. The PRD settled it. Everyone moved forward.”
Sarah Mitchell
Product Lead, Forge
“The AI understood our product better than we did. The specs proved it.”
Tom Harrison
Founder, Velocity
“We went from idea to production-ready specs in an afternoon. No rework needed.”
Lisa Patel
Solo Founder, Clarity

Questions
Everything you need to know about our plans and billing.
Can I cancel anytime?
Yes. Cancel your subscription at any time with no penalties or hidden fees. Your access continues through the end of your billing cycle.
What are credits?
Credits are used when the AI generates content — starting a project uses 1,250 credits, each chat message uses 5, and regenerating an artifact uses 100. All core features are available on every plan.
Can teams use one account?
Free supports 1 user, Base supports up to 2 team members, and Plus offers unlimited workspace members who can collaborate on projects together.
What's included in early access?
Plus members get first look at new features before general release. You shape the product roadmap with your feedback and requests.
Do you offer invoices?
We send invoices automatically to your email each billing cycle. Download them anytime from your account dashboard for your records.
Your next build deserves
architecture, not guesswork.
Every hour you spend without a spec is an hour you'll spend rewriting later. Get your architecture right before line one.
