Whimsical

A diagramming tool that runs in the browser

Whimsical is a web application for flowcharts, wireframes, diagrams and whiteboards. Its makers describe it as a single-page app: most of the logic runs in the browser and syncs changes to a cloud backend, which in turn tells the browser about edits made by other users. The application's data is stored in a PostgreSQL database.

Drawing flowcharts quickly

Whimsical's flowchart pages stress speed. Predictive shapes and simple keyboard shortcuts help people draw processes and user flows without fiddling over styling, so time goes on the ideas themselves. An AI feature can generate an editable flowchart from a text prompt.

Working together on a board

Several people can edit a board at once, with comments attached where the work is happening. Templates made by experts give a starting point, version history is kept, and integrations carry a flowchart into tools such as Notion, Jira and Slack. Whimsical says millions of people use its flowcharts to break down complex ideas.
