## Overview

- **Who it's for**: Product, design, and engineering teams who want a fast, low-friction way to sketch flowcharts, wireframes, mind maps, and docs together, rather than a heavyweight technical-diagramming or CAD-style tool. It suits startups and cross-functional teams doing product discovery, brainstorming, and process mapping more than enterprises needing precise UML/ERD modeling or Visio migration.
- **What you get**: An infinite-canvas "Boards" workspace covering flowcharts, mind maps, wireframes, and diagrams, plus separate Docs and Projects surfaces, real-time multiplayer editing, comments, version history, and a large library of expert templates (including UML and ERD template boards built from generic shapes). Whimsical AI (powered by Claude) can generate flowcharts, mind maps, and wireframes from a prompt, and Mermaid code can be pasted in as an editable flowchart or sequence diagram.
- **How it works**: You create Boards or Docs inside a Workspace, dragging predictive shapes and connectors on an infinite canvas or starting from a template; changes sync live to collaborators with comments and version history. Content exports as PNG, PDF, or SVG (or copies out as Mermaid), integrates with tools like Slack, Jira, Notion, and GitHub via backlinks/embeds, and is available free forever on a limited Starter plan or on paid Pro/Business plans for expanded storage, guests, and admin/security controls.
