markerNote - web, PDF highlighter & notes

markerNote is a powerful Chrome extension enabling users to highlight text richly on both webpages and PDF files. With no signup required and a privacy-focused design, it avoids intrusive permissions while offering features like multi-color highlighting, adding comments, and native Edge Chromium support. Highlights are saved in markdown format and auto-organized by domain, date, and folders for easy management.

The extension supports real-time syncing of notes with local storage and popular cloud drives such as Google Drive, OneDrive, and Dropbox, as well as integration with tools like Notion and Obsidian. It includes keyboard shortcuts for efficiency, lightweight design (only 70KB), and capabilities for exporting and backing up notes. markerNote also features a PDF highlighter, image and YouTube transcript highlighting, and a neat side panel interface for note management. These features make it ideal for students, researchers, and professionals who need organized, accessible, and editable highlights across browsers and devices.
