What is Excalidraw?
Excalidraw is an online whiteboard built for drawing, diagramming, and brainstorming on an infinite canvas. It produces hand-drawn-style visuals — flowcharts, wireframes, UML diagrams, system architecture maps, and presentation slides. The tool fills the space between heavyweight design software and disposable scratch notes. You get real-time collaboration, generative AI that turns text into diagrams, and export to multiple file formats. A free, open-source editor runs straight in the browser with no account needed. A cloud version adds persistent storage, team workspaces, and live presentation tools.
Features & Benefits
- Infinite Canvas — give your drawings unlimited space, whether you’re mapping a single flow or building out a full system diagram.
- Full Drawing Editor — draw with a complete set of tools including shapes, arrows, freehand lines, and text on a flexible open canvas.
- Text to Diagram (Generative AI) — generate and edit diagrams from natural language input using a chat interface or directly inside the editor.
- Wireframe to Code (Generative AI) — turn whiteboard wireframes into interactive mockups and working code output.
- Presentations — build slide-based presentations from canvas frames and deliver them live, right inside the online whiteboard.
- Real-Time Collaboration — share a link and edit the same canvas together with collaborators at the same time.
- Voice Hangout & Screensharing — talk and share your screen with collaborators without leaving the whiteboard session.
- Comments — leave feedback directly on canvas elements so teams can review and respond asynchronously.
- View-Only Access — send a read-only link that lets people see the canvas without touching the content.
- Cloud Workspace — save scenes automatically and pull them up from any device through a personal dashboard.
- Team Workspaces — bring members, scenes, and permissions together under a shared team environment.
- Collections — group scenes into organized collections so teams can navigate projects without the clutter.
- Personal Library — save reusable shapes and sketches server-side so they’re available across sessions and devices.
- Public Libraries — browse and import pre-built sketch libraries contributed by the community.
- Export (PNG, SVG, JSON) — save canvas content to PNG, SVG, or JSON to use in other tools or documentation.
- Export (PDF & PPTX) — export presentations and scenes directly to PDF or PowerPoint files.
- Embeddable Links — drop a read-only canvas view into external pages or documents with an embed link.
- Open-Source (NPM Package) — self-host the core editor using the open-source NPM package.
Real-World Applications
Product and engineering teams planning software architecture can get a lot out of Excalidraw as an online whiteboard. A backend engineer can sketch out a service dependency map mid-meeting without switching tools. A product manager can share a rough wireframe via a read-only link and collect structured comments from stakeholders before anyone writes a line of code. The text-to-diagram AI feature can take a written spec and turn it into a flowchart in seconds, cutting out a big chunk of manual drawing work.
Design teams working on early concepts may find the hand-drawn aesthetic actually useful, not just charming. It keeps feedback sessions focused on structure and layout rather than color choices and polish. A UX designer presenting rough flows to a client can run a live presentation straight from the canvas. The wireframe-to-code feature can give developers a head start on building interfaces from those same rough sketches.
Educators and workshop facilitators running remote or hybrid sessions can use the online whiteboard to keep distributed groups engaged and working together. A teacher can open a shared canvas and have students contribute diagrams in real time during a lesson. Outside participants can join without creating accounts, which removes a common barrier in workshop settings. The presentation mode lets facilitators move through structured content while keeping drawing tools close at hand.
Consultants and business analysts working through process mapping with clients can use Excalidraw to capture and refine ideas during live conversations. A business analyst can build a UML or process flow diagram on a shared canvas while the client watches and contributes. When the session wraps up, the finished diagram goes straight to PDF or PPTX for the formal deliverable. Workspace collections keep different client projects clean and separate from one another.
