Introducing Coherence, a Mac browser for people who read to learn.
📖 Clutter-free reading, on pages and PDFs
🖍 Highlights and notes that stay put
✨ Ask AI about what you're reading
📚 A library you can search and ask
Free for Mac → coherencebrowser.com
7/ And it's a great everyday browser.
Vertical tabs, a built-in ad blocker, a session manager, Split View, a ⌘K command palette, sleeping tabs and Chrome extensions. Native WebKit and SwiftUI.
6/ Capture anything. Ask it later.
Save a page, a PDF, a post or one paragraph, with your highlights and notes. Search your library by meaning, and ask questions across everything you've kept, with answers that cite your sources.
5/ Make anything interactive.
Turn an article or a paper into something you can drag, switch and try: charts, simulations, quizzes and flashcards, all built from the source itself.
4/ PDFs, actually understood.
Coherence breaks a paper into its titles, figures, tables and equations, turns it into clean Markdown, and pulls out claims, evidence and a glossary, each linked back to the passage it came from.
3/ A new way of reading with AI.
Select a sentence and look at it through a lens: Explain, Skeptic, Evidence, Context.
Or open the side panel to chat about the page, go deep on one idea, or explore where it leads.
2/ Mark what matters, and it stays put.
Highlight a passage, pin a note beside it. Your marks follow the page into Reader, Focus and the PDF viewer, and they're still there when you come back next month.
1/ Read with focus.
Reader strips an article down to its words, in your font, size and theme. Clarity keeps the page's own look, minus the clutter.
Focus lifts one passage, post or video into a calm frame of its own.
