Save links, organise them into tagged collections and find your bookmarks across browsers and devices.
Save links, organise them into tagged collections and find your bookmarks across browsers and devices.
Replace only the saved-link library, tagging and collection-organisation part of paid Readwise/Reader when users primarily need to keep and retrieve links. Does not replace Kindle highlight sync, spaced-review emails, offline full-text reading or every Reader capability.
Replaces saved-link capture and organisation, not the whole Readwise highlight-review system or Reader experience. Full-text search, permanent archived copies, automatic backups, reminders and duplicate/broken-link detection are Pro extras. File uploads on Free total 100MB per month. A saved bookmark does not guarantee its source remains available. Account and hosted service required; the cited author bought Pro, so that account’s advanced features are not evidence they are free.
Each comparison covers the workflow described above, rather than every paid feature.
