# Priorative > Priorative is a browser-based product design workspace. Plan with mind maps, IA maps, database diagrams, API design, system design (Mermaid), roadmaps, and timelines — organized by project, with data stored locally in your browser. Priorative helps product teams, architects, and solo builders think through structure, APIs, data, infrastructure, sequencing, and navigation without switching tools. Each project shares one sidebar and integrated modules. ## Modules - [Mind map](https://priorative.app/): Brainstorm and prioritize on an interactive canvas; export maps as JSON or images. - [DB diagram](https://priorative.app/): Visual entity-relationship style tables with columns and links between tables. - [API designer](https://priorative.app/): Node-based canvas for HTTP endpoints, methods, and API flows. - [Roadmapper](https://priorative.app/): Initiative and dependency diagrams for product roadmaps. - [Timelines](https://priorative.app/): Milestone and release timelines with layout variants and PNG/SVG/PDF export. - [IA map](https://priorative.app/): Information architecture — page tree, labels, and navigation metadata. - [System design](https://priorative.app/): Mermaid architecture diagrams for DevOps and system architects — flowcharts, sequence, C4, templates, and technology snippets. ## How it works - Open the app in a modern browser; no account is required for the local workspace. - Create projects from the sidebar; switch modules without losing project context. - Diagrams and documents persist in browser storage on the device. - Supports light, dark, and system appearance. ## Technical - Single-page application built with React and Vite. - Client-side only: planning data does not leave the browser unless the user exports it. ## Optional - Site map: https://priorative.app/sitemap.xml - Robots: https://priorative.app/robots.txt
