Local-first Mac library for links, images and PDFs, sorted by on-device AI
Apple Foundation Models run locally to tag and summarize every link, image and PDF you save, so your library organizes itself with no setup and no cloud round-trip.
Search the text of every article, note and PDF in your library instantly, even with no connection.
Save a URL, a screenshot or an entire folder of documents the same way, and read any of them in a clean, ad-free reading view.
No account, no cloud sync and no tracking. Everything lives in a local database on your Mac unless you deliberately bring your own API key.
