One form in, a complete product requirements document out, plus the diagrams that usually take a separate tool.
Overview and goals, architecture, API, database and ERD, AI prompt design, security, testing, deployment and roadmap in one document.

A Mermaid system diagram and a PlantUML entity-relationship diagram, generated from the same brief and rendered as images.
Download the spec as Markdown or copy it straight into Notion, Linear, GitHub, or your repo.
Start from a mobile app, web app, API, SaaS, game or IoT preset so the output matches the product type.
Call the same engine from your own scripts and CI with a small OpenAI-compatible HTTP API.
Give it a name and a sentence or two. Optionally add features, users and your stack.
The model writes the full PRD section by section, then the architecture and data diagrams.
Copy or download the Markdown and drop it into your planning tool of choice.
