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.
AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
