A guide for wandering eyes, a spotlight for busy pages, notes beside the paragraph, and spaced review that keeps what you understood. Calm by design — and your library quietly stays your own.
01Paste a PDF link, drop a file, or pick one from a private GitHub folder.
02Page notes, highlights, and AI questions stay attached to the paper.
03Shared tags reveal a small network instead of another filing cabinet.
Ninety seconds, no narration: a paper opens, the guide follows your pointer, a column snaps to full width, and the same page reflows to read like a book on a phone.
Papers touch when they share a tag. Keep the tags loose and human—“tomato metabolism,” “good figure,” “method to steal”—and the structure will emerge on its own.
Review
Highlights, notes and saved questions ripen into cards a day after you make them, then return on a spacing schedule. Explain each one from memory before grading yourself.
Focus one line—or a vertical column.
