Excalidraw is a virtual whiteboard application that integrates AI to enhance its drawing and collaboration features.

It stands out for its simplicity and ease of use, allowing users to create sketches that resemble hand-drawn diagrams. Excalidraw is particularly useful for creating flowcharts, wireframes, and mockups, catering to both professional and casual users.

With the addition of AI features it is now possible to directly generate diagrams from text prompts or HTML from a wireframe. This has proven especially useful to quickly get a prototype up and running from a simple drawing with a few annotations. Excalidraw allows you to do this without requiring a subscription on their website, instead allowing users to provide their own personal OpenAI API key (OpenAI Docs).

The platform supports real-time collaboration, making it ideal for team brainstorming and remote work. The base version is free (own OpenAI API key required) and available on Github as open source for developers.
