PageMark: Web Highlighter, Flashcards, Reader Mode & Bookmarks

Highlight anything you read on the web, keep your notes with it, and turn what matters into flashcards. PageMark is free forever, works offline, and never asks you to make an account. HIGHLIGHT AS YOU READ • Select text on any page and pick a color - yellow, green, blue, pink, or your own. • Highlights come back every time you revisit the page. • Add a note to any highlight, and tag it so you can find it later. • Alt+1 to Alt+4 to highlight without reaching for the mouse. FIND IT AGAIN • Search across every highlight, note and tag from the sidebar. • Filter by color or tag, sort by newest, oldest, color or site. • Group by page, with pinned highlights kept together at the top. • Jump straight back to any highlight on its original page. STUDY WHAT YOU SAVED • Turn any highlight into a flashcard in one click. • Review in a focused study session - cards you don't know come back before you finish. • Track new, learning and known cards, plus a daily streak. READ WITHOUT THE CLUTTER • Reader mode strips the page back to the article. • Four backgrounds, three typefaces, adjustable size, spacing and column width. • Search within the article, jump by heading, save it as Markdown. YOUR NOTES STAY YOURS • Everything is stored on your own device, in your browser. • No account, no sign-in, no sync server, no analytics, no tracking. • PageMark makes no network requests at all. • Export any time to Markdown, Obsidian, Notion or JSON - and import JSON back. ALSO • Bookmark pages you want to come back to, with their own tags. • Light and dark themes. • Move the sidebar to either side and resize it. • Disable PageMark on any site you like. Free forever. Not a trial, not a freemium tier - there is nothing to buy.
