Language immersion extension · Fluidity family
Your personal reading library
Save multiple texts, organize collections, search documents, resume reading and listen with sentence-by-sentence text-to-speech.
Bring a text, return later
Save supported webpage text, paste a passage, or import TXT, Markdown, SRT or VTT. Unprotected EPUB files up to 50 MB import as text-only chapters with chapter navigation. Documents, source links and approximate reading progress stay on this device, separated by guest or account identity.
Read, listen and investigate
Reader uses the same word card and learner marks as webpage immersion. Read-along highlights sentences and offers pause and speed controls; voices depend on your browser and installed languages. Translation is requested one sentence at a time on click. Familiar-word estimates are approximate, not comprehension scores.
