WyzeSketch

WyzeSketch is a virtual whiteboard that makes your diagrams look hand-drawn. Draw boxes, arrows and shapes, drop in text and images, and get a result that feels like a sketch on paper rather than a rigid chart. That makes ideas feel open to change, which is exactly what you want in the early stages of a project.

It is a native Mac app built on the open-source Excalidraw editor, packaged to work with your files: each drawing is saved as a regular file on your Mac, you can keep several open in tabs, and nothing needs an account or an internet connection.

What you get

1. A full set of drawing tools — Rectangle, diamond, ellipse, arrow, line, freehand pen, text, images and an eraser, plus a hand tool to pan and a lock to keep a tool selected while you draw several shapes.
2. Diagrams that look hand-drawn — Shapes and lines get a natural, sketched look, so a rough idea does not look finished before it is.
3. Your drawings are plain files — Each drawing is saved as a standard .excalidraw file that you keep where you want. Saves are written safely, so a crash cannot leave you with half a drawing.
4. Several drawings in tabs — Keep multiple drawings open at once and switch between them, with a marker on the tabs that have unsaved changes.
5. Autosave once a file exists — After you save a drawing for the first time, your changes are saved automatically as you work.
6. Export to PNG, SVG or PDF — Export your board as an image, as a scalable vector (SVG) or as a PDF to print or send. The app tells you if there is nothing to export.
7. Open by dragging a file in — Drag an .excalidraw drawing onto the window to open it, or use File > Open.
8. Light and dark — Switch between a light and a dark board to suit your room or your slides.
9. Won't lose your work — If you close a drawing with unsaved changes, WyzeSketch asks whether to save first.
10. Private by design — No account, no cloud, no tracking: your drawings stay on your Mac. Available in English and French.
