Margin Notes

Take notes on anything you read, right where you read it. Margin Notes is made for proofreading, reviewing, and giving feedback on content online. Select some text, right-click it, and add a note with a label such as Question, Correction, or Rephrasing. When you finish a page, open all its notes in one place and copy them as Markdown, ready to send to a colleague or paste into an LLM. HOW IT WORKS 1. Select some text on a page. 2. Right-click and choose "Add note", or press Alt+Shift+N. 3. Pick a label, write your note, and press Ctrl+Enter. Done. FEATURES • Labelled notes: Comment, Question, Correction, Rephrasing, Suggestion, and Praise. Rename them, recolor them, or add your own. • One folder per page: every page you annotate gets its own folder. Different pages of the same site stay apart. Tracking tags and anchors in the address (after "?" or "#") are ignored, so one article stays one folder. • Export in one click: copy a page's notes as Markdown, or download them as a .md or .txt file. You can also download all your notes at once. • Works almost everywhere: web pages, PDFs, and local files that you open in Chrome. • Keyboard shortcut: Alt+Shift+N by default. Change it at chrome://extensions/shortcuts. • Edit and delete: fix a note later, or clear a whole page when you are done. • Light and dark mode: follows your system theme. PRIVATE BY DESIGN • Your notes stay on your computer. There is no server, no account, and no sign-up. • No analytics, no ads, and no tracking. The extension makes no network requests. • It never changes the pages you visit. It reads only the text that you select, and only when you ask for a note. • The whole extension is about 28 KB. TIP FOR LOCAL FILES To take notes on files opened from your computer, open chrome://extensions, press Details on Margin Notes, and turn on "Allow access to file URLs".
