Reading without friction
Use search to find a book, filter by topic, English level or length, then open the reader. Saved books, progress, themes, bookmarks, highlights and reflections stay in this browser.
Select a word or short phrase and choose Look Up Selection to open a dictionary, hear it aloud or save it as a highlight.
Use Line Focus to dim surrounding paragraphs, Keep Screen Awake on supported devices, or opt into continuous reading after 95% of a chapter. Press F for immersive mode.
Where is my progress saved?
On this device, in browser storage reserved for Linden. Reading Insights lets you export a backup or delete the data.
Can I sync across devices?
There is no account sync. You can export a Linden JSON backup and import it in another browser yourself.
Does word lookup upload the book?
No. Only the selected word or phrase is sent if you choose to open the external dictionary link.
What does the English level mean?
Calibration V2 is a provisional CEFR-aligned reading range. Complete texts use sampled language signals; guide-only records use edition and source metadata.
