Markpin – Web Highlighter & Reading Notes

Read the web with a highlighter: mark what strikes you, jot notes as you go, bookmark your spot. Saved as Markdown your AI can read.

Markpin brings what you do with a paper book to the web: highlight a line, write a thought in the margin, leave a bookmark, open it again later. What you mark and note as you read slowly becomes your own thinking. A browser bookmark keeps a link. Markpin keeps what you marked and what you thought while reading. MARK AS YOU READ • Select a sentence to highlight it in one of four colors. • Add a mark: ? for a question, ! for something new, × for a disagreement, ★ for a key point. • The note box asks first: "Why did you mark this?" Write the thought it sparked as a note, right there. • Drag a rectangle over a passage or an image to keep it as a clip. • The floating button or a keyboard shortcut saves the whole page. PICK UP WHERE YOU STOPPED • Leave a bookmark and continue from where you stopped next time. • A thin rail along the left edge shows your marks and where you left off as dots; click one to jump back. • When you finish, mark the page as read and sum it up in one line, from memory. • Didn't finish it? Mark it as skimmed, so the record stays true. • Your highlights and notes are still on the page when you return. FIND IT AGAIN • Search the full text of everything you saved and see the matching snippet. • Rename and merge tags, filter by highlight color and mark, and get a one-line summary written by Chrome's on-device model. YOUR FILES, YOUR MARKDOWN • Each page becomes one Markdown file in a folder you pick or in your Google Drive. • Obsidian opens it with clean properties, ==highlights== and callouts. • Turn on the option and deleted pages move to .trash. YOUR AI READS IT AND WRITES BACK • Claude Code, Claude Desktop, Cursor and other MCP clients search and read your pages through the local @markpin/mcp server, and can leave notes and bookmarks for you. WHERE YOUR DATA GOES • It starts in your browser. Nothing to set up, and it works offline. • Connect a folder on your computer or your Google Drive, and the same files sync there. Nothing else gets uploaded. • The MCP server runs on your computer and reads that folder, so your AI tools can see your pages without anything leaving your machine. • Summaries and tag suggestions use Chrome's built-in on-device model. You can turn them off in the options. There is no server, no account and no analytics. The files are yours.
