READ ALOUD - Dual-layer sync: the current paragraph is highlighted while the sentence being spoken lights up. - Turn any EPUB or PDF into an audiobook you can follow word by word. - Choose browser voices for offline TTS, or natural neural cloud voices. - Speech speed from 0.5x to 2.0x. - Ruby annotations, brackets and citation markers are cleaned before they are spoken. - Click any sentence to start listening from exactly there. STUDY TOOLS - Chapter summaries at the depth you choose. - Bilingual reading: side by side, original only, or translation only. - Character relationship maps and plot timelines. - Chapter review questions with explanations. - Export notes and summaries as EPUB or PDF. - Generated content is cached locally, so it opens instantly next time. SYNC (OPTIONAL) - Synchronize reading progress, bookmarks and highlights over WebDAV: Nextcloud, Nutstore or your own server. - Requests go only to the servers you configure, and always over HTTPS. YOUR BOOKS STAY YOURS - Library, reading progress, bookmarks and notes are stored in your browser. No tracking, no analytics. Note: TTS narration uses your browser's built-in speech engine by default and works offline. A cloud narration endpoint can be configured in settings. Install MoReader for a focused, comfortable reading and listening experience, for both EPUB and PDF. Security upgrade: cloud narration and cloud sync now use HTTPS encrypted transport, and saved server addresses migrate automatically.
