Description

Notes on the web that stay where you put them. Draw, highlight and comment on any webpage — stored on-device, works offline. Annotate any website like it’s your own canvas. Draw, highlight, and add sticky notes anywhere on the web. It works on every website and PDF, and you can optionally save your annotations directly to the page so they’re still there when you come back later. Completely free to use, with no data collection.
