Built for researchers, students, and knowledge workers who need to move PDF annotations into their note-taking systems.
PDF annotations — highlights, comments, and sticky notes — contain some of the most valuable insights from your reading. Yet extracting them from a PDF has historically required expensive desktop software or cloud-based services that upload your private documents to remote servers. We set out to change that.
Every PDF you process is parsed entirely in your browser using WebAssembly. Your files never leave your device. There are no servers receiving your data, no third-party APIs analyzing your documents. You can verify this yourself: disconnect your internet connection after loading the page, and the tool continues to work perfectly.
As avid users of knowledge management tools like Obsidian and Notion, we were frustrated by the gap between reading a PDF and getting those annotations into our note systems. Manual copy-paste was tedious, existing tools were either expensive cloud services or clunky desktop applications. We built a tool that is fast, free to start, and respects your privacy absolutely.
Our extraction engine runs a compiled PDF parser directly in your browser via WebAssembly, delivering native-code performance without any server round-trips. This approach supports the full range of PDF annotation types — highlights, underlines, strike-throughs, sticky notes, and nested reply chains — while maintaining complete data sovereignty.
