Sketch ideas, build simple diagrams, annotate images, and arrange text and shapes on a private browser whiteboard.
Use the pen for quick sketches, then combine lines, arrows, rectangles, ellipses, and editable text to organize a flowchart, wireframe, lesson, meeting note, or visual explanation.
Select objects to move, resize, rotate, duplicate, recolor, or change their layer order. Add local images when a diagram needs a reference, screenshot, logo, or background element.
Undo and redo changes throughout the current editing session with no fixed history limit. Save the editable project as JSON to continue later, or export a flattened PNG, JPG, or SVG for sharing and documents.
Everything runs in your browser. Drawings and imported images are not uploaded to a server.
