Laofu Canvas
Turn your Mac screen into a writing surface. Mark the important parts while explaining, reading, or presenting.
Explain things right where you see them
Laofu Canvas is a transparent drawing layer over your Mac screen. Write, circle, and point over slides, web pages, or other on-screen content without moving it into another app. Switch back to mouse pass-through to continue using the app underneath.
Write, then return to your work
- Toggle between ink and mouse pass-through with a keyboard shortcut.
- Use eight tools: pen, highlighter, eraser, line, arrow, rectangle, ellipse, and pointer.
- Choose colors and stroke widths, undo, redo, or clear the canvas.
- Hide marks when leaving ink mode, then keep or clear them when you return.
- Keep the drawing locally on your Mac, with no account required.
Scope and availability
For macOS 14 or later, with Apple Silicon as the primary target. The first version supports a single display. Marks stay fixed on the screen and do not follow scrolling pages. Screenshot export, AI, OCR, and cloud sync are not included.
Available on the Mac App Store. Check the store for local pricing, device compatibility, and availability.
What you can use it for
- Circle key details and sketch an explanation while teaching.
- Add temporary notes and pointers during a presentation.
- Sketch connections while reading, then return to the original app.
