Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.

What it does, concretely

Drawing a clear diagram takes time, and traditional tools often come with complex interfaces or costly subscriptions. Excalidraw offers a free online whiteboard, with no account required, where you can create hand-drawn style diagrams in seconds.

The tool works directly in the browser: you draw shapes (rectangles, circles, arrows, free lines), add text and images, then export the result as PNG, SVG, or an .excalidraw file. Real-time collaboration is built in via a shareable link, and all sessions are end-to-end encrypted. The app also works offline thanks to PWA technology.

Excalidraw suits anyone who needs to quickly sketch an idea: developers, designers, teachers, project managers, or students. The deliberately sketchy style makes diagrams approachable and non-intimidating in presentations or meetings.

However, if you need polished visuals, precise vector graphics, or advanced document management, other specialized tools will be more appropriate. Excalidraw is also not a presentation or word-processing tool.

What it offers

·Infinite whiteboard in the browser, with no installation or account required.
·Hand-drawn style for all elements: shapes, arrows, text, and free-draw.
·Real-time collaboration via a shareable link, with end-to-end encryption.
·Export to PNG, SVG, clipboard, or a reusable .excalidraw file.
·Dark mode and localization support in multiple languages.
·Customizable shape libraries to enrich diagrams.
·Offline functionality via PWA support, with automatic saving in the browser.
·AI-based diagram generation (as noted in the existing tool summary).

Our tips

Use the built-in shape libraries to speed up the creation of recurring diagrams without redrawing everything by hand.
Share a read-only link to present a diagram without the risk of others accidentally modifying it.
Export to SVG when you need to embed the diagram in a document or presentation: the format stays sharp at any size.
Enable dark mode for comfortable work in low-light environments, accessible directly from the interface.
Save regularly by exporting the .excalidraw file: it preserves all drawing data and can be reopened and edited later.

Watch out

Data is saved locally in the browser by default: clearing the cache or switching devices without exporting the file will result in lost work.
Advanced collaboration and project management features (history, folders, etc.) are reserved for Excalidraw+, the paid version.
