Highlight and write margin notes
Mark passages in four colors, attach a note to anything important, and review them all from a side panel. When the exam approaches, export the whole set as Markdown — clean, sorted by page, ready to drop into Notion or Obsidian.
Resume exactly where you stopped
Each document remembers its own page and progress. Close the tab, come back tomorrow, and you land on the same paragraph — no scrolling back through 600 pages of a textbook.
Dark mode for late-night study
A dim, calm dark theme that keeps images natural and text crisp. Sepia for long afternoons, light when the sun is up. Switch with one tap.
Free, no signup, nothing uploaded
PDFcove opens your textbooks locally in the browser. No account, no email, no upload. Useful when the PDF is leaked-prevention-watermarked or simply when you don’t want a third party to know what you’re reading.
