Rootnote
Margin notes synced across everything you read; sync can lag.
Product screenshot
Rootnote is a quiet idea done well: your margin notes and highlights follow you across the web, PDFs, and ebooks, and land in one searchable place. For anyone who reads across formats and loses track of what they marked up, it closes a real gap.
Sync isn’t instant — a note made on mobile took a minute to appear on the desktop more than once — and there’s no highlights-only view yet. Small frustrations against a genuinely useful core.
