Pen Laser

Draw on any web page with a real pen cursor, and point with a glowing laser pencil. Built for live teaching and demos.

Pen Laser lets you draw on any web page while you teach, present, or record a demo. A REAL PEN CURSOR The cursor is a pen with its nib exactly where the ink will land, so you never hunt for a one-pixel dot. It stays visible on pen tablets, even while the nib touches the tablet, and it shows up exactly once in screen recordings. A PRESENTATION LASER Press Alt+L, then press and drag. A pencil with a glowing red tip lays down bright laser ink that stays while you keep pointing, then fades out on its own three seconds after you stop. Moving the mouse without pressing does nothing, so it never distracts while you talk. EVERYTHING YOU NEED, IN ONE SMALL TOOLBAR - Pen, highlighter, line, arrow, rectangle, ellipse, and text - Stroke eraser, exact undo and redo, clear page - Six colours and adjustable widths - Pass-through mode to click links and scroll without losing your notes - Save a PNG screenshot of the page with your notes on it - Drag the toolbar anywhere NOTES STAY ON THE CONTENT Marks are anchored to the page, so they scroll with the text you drew them on. KEYBOARD FIRST, AND EDITABLE Alt+A shows or hides the toolbar. Every tool and action has a key, and every key can be changed from the toolbar's Keyboard shortcuts panel. PRIVATE BY DESIGN Pen Laser has no account, no analytics, and no network requests. Your drawings never leave the tab, and only your preferences (tool, colour, width, shortcuts) are saved, on your own computer.
