PRD Generator
Turn a product idea into a build-ready PRD
What Is the PRD Generator?
The PRD Generator turns a short description of a landing page, web app or mobile app into a product requirements document you can build from: goals and metrics, users and journeys, prioritised features with acceptance criteria, pages or screens, a design system with colour tokens, architecture and data model, SEO and analytics, quality requirements, a delivery plan and a ready-to-paste prompt for an AI coding agent.
Key Features
From an Idea to Something Buildable
A one-paragraph idea leaves an engineer, or an AI agent, guessing about everything that matters: what counts as done, which features come first, what the data looks like. The PRD answers those questions in one document, with assumptions called out as open questions instead of buried.
Your Brand and Your Stack
Add brand notes (colours, fonts, voice) and pick a stack, or let Claude propose them. The palette comes back as named tokens you can see side by side, and the architecture section is written for the stack you chose, so the document fits the project you're actually starting.
Ready for AI Coding Agents
The last section is a prompt built from the plan: product, stack, must-have features with their acceptance criteria, design tokens and milestones. Paste it into Claude Code, Cursor or a similar agent along with the PRD and it has what it needs to start.
Common Use Cases
- Scoping an MVP before hiring or building
- Briefing an agency or freelancer on a landing page
- Giving an AI coding agent a complete spec
- Turning stakeholder notes into a shared document
Frequently Asked Questions
Is the PRD Generator free?
Yes. It's free with a ProxyHorizon account, and every account gets 25 runs a day shared across all our data tools. You can read about the tool without signing in, but running it needs an account because each run fetches live data.
How long does it take?
Usually one to two minutes. Claude plans the product and writes every section in one pass.
Concise or detailed?
Concise gives 5 to 7 features with 3 acceptance criteria each and a short plan. Detailed gives 8 to 12 features, more criteria, more screens and a longer delivery plan.
Can I edit it?
Download the Markdown and edit it in any editor, Notion or Google Docs. The features table also exports as CSV.
Do you store my results?
No. We log which tool you ran, what you entered and when, so we can apply the daily limit. Results aren't saved, so export them as CSV or JSON if you want to keep them.
