prd.c1v.ai turns one sentence of product vision into technical drawings, decision matrices, engineering specs, and investor artifacts — so your LLM, your engineers, and your investors all see the same system.
Decision matrices, not vibes.
Every architectural choice traced back to a math-cited Pareto frontier — Crawley-discipline analysis built in.
Technical drawings for your LLM.
Context diagrams, use case diagrams, and engineering specs your LLM can actually act on — Cursor and Claude Code ship the right thing on the first prompt.
Investor artifacts on day one.
Synthesis bundle exports as PDF, PPTX, and JSON — pitchable without a slide-design week.
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 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.
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.
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
Chat about your product idea. Get engineering-ready specs.
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.
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.
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
Type your idea in plain English. No templates, no forms — just tell the AI what you want to build and who it is for.
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.
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.
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

Everything you need to know about our plans and billing.
Yes. Cancel your subscription at any time with no penalties or hidden fees. Your access continues through the end of your billing cycle.
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.
Free supports 1 user, Base supports up to 2 team members, and Plus offers unlimited workspace members who can collaborate on projects together.
Plus members get first look at new features before general release. You shape the product roadmap with your feedback and requests.
We send invoices automatically to your email each billing cycle. Download them anytime from your account dashboard for your records.
Every hour you spend without a spec is an hour you'll spend rewriting later. Get your architecture right before line one.
