What it does

Written by AI from the README

Draws editable comment cards in the margins beside PDF pages, linked to their annotations by leader lines. Edits with basic formatting sync back to the annotation comment, with a toolbar toggle and export or import of annotation notes as JSON.

Annotation comments normally sit in the reader sidebar, away from the page. This puts them beside the text so you can review and revise without switching focus.

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
