A reading session
Say you save a long article. In Nisaba, open it in the reader, select two passages, pick a color for each and add a note under one. Later, open Highlights in the sidebar, filter by color and copy a highlight as Markdown. Nisaba is built around web pages and follows RSS feeds too. It has no EPUB support and no newsletter inbox, so if those are your main reading, check Reader first.
Moving over
Reader exports your library as CSV. Nisaba has no Reader-specific import, and that CSV was not tested here. A CSV with a url column and a header row goes through the Spreadsheet import, with optional title, note, tags, folder and created columns. Nisaba also imports bookmark files, Raindrop and Instapaper exports and a Pocket export file. You see a preview before anything is imported.
Nisaba's limits
- There is no native mobile app yet. On an iPhone or iPad, Safari cannot add Nisaba to the Share menu, so you add Nisaba to your Home Screen and paste links.
- The extension is for Chrome only.
- Nisaba needs an internet connection.
- Search by meaning and summaries use AI credits. AI output can be incomplete or wrong, so check important details at the sources named.
