Annotator by rabbitxone

Annotator brings margin notes to the web. Highlight a passage, add a thought, and it will be there the next time you open the page. Every note also lands in one dashboard, so pulling together sources for an essay, a thesis or a work project takes minutes instead of an afternoon.

HOW IT WORKS
Select some text and pick a color, or press Alt+Q (Ctrl+Q on a Mac). Alt+W highlights and opens a note straight away. Click any highlight to edit its note or change its color. A short guide with a practice paragraph walks you through the basics after installing.

WHAT YOU GET
• A side panel (Alt+X) with every highlight on the page in reading order, plus a note for the page as a whole
• Colors with meaning: rename them to "Key idea", "Evidence", "Question" or anything else, add up to 60 and give each one a key
• Notes with bold, italics, lists and links
• Notes that survive edits: if a page changes, just select the new wording and reattach the note
• Quote with a link: copy a passage with your note and a link that jumps straight back to it
• Export to Markdown for Obsidian or Notion, CSV for Excel or Google Sheets, or a full JSON backup you can import on another computer
• A dashboard with search, filters by color, grouping by site and undo
• Works on local files and PDFs saved as web pages, too

Annotator stays quiet in web apps like email and chat and switches on for articles, so it never gets in the way.
