A bookmark. A whole toolkit.

[ INSTALL ]

Make a little room.

Show your browser’s bookmarks bar and drag the Bookmarklet button above into it. That’s the installation.

[ ANNOTATE ]

Point out the details.

Open a page and click your new bookmark. Draw a guide, circle a detail, or leave a note exactly where it belongs.

[ SHARE ]

Let the picture explain.

Press H to hide the controls. Take a screenshot and share it with a teammate—or your AI.

Precise when it matters.

Use a 32 px grid, adjustable margins, and full-page guides to spot alignment issues. Hold Shift for perfect circles and snapped arrows.

Change your mind freely.

Drag marks to move them. Double-click text to edit it. Choose a color, undo a change, or clear the page and start fresh.

Grid settings, shortcuts & the finer details

Grid spacing: 8, 16, 24, 32, 64 or 128 px. Left/right and top/bottom margins default to 32 px. Arrow keys change margins by 8 px; Shift changes them by 1 px. Cmd + Up/Down jumps through 8, 16, 32, 64, 128, 256, 512 and 1024. Live width and height measurements fade after a pause. The grid is a visual reference; it doesn’t snap your marks.

Drag the toolbar header to move it. H hides it and enables Browse mode; H again restores your previous tool. Escape asks before closing and discarding your annotations. Delete removes a selected mark; Cmd/Ctrl + Z undoes changes outside Browse mode. Shortcuts leave text fields alone.

A small space to experiment.

Line up the edges. Point at the gap. Add a note. This page is your first canvas.

Marks stay fixed to the viewport and disappear when you refresh or close. Browser settings pages, some PDF viewers, and sites with restrictive security policies may block bookmarklets.
