AccelaReader vs Ledor

AccelaReader is an online RSVP reading tool that flashes imported words in sequence for faster-reading practice. Users can paste text into the reader, choose a reading speed in words per minute, and set how many words appear at once. Display controls cover window dimensions, font size, font color, background color, and alignment. Reading options include variable pacing, sentence or paragraph chunks, pauses, and skipping stopwords. Keyboard shortcuts handle starting or pausing, restarting, loading text, opening settings, moving through the material, and changing speed. A bookmarklet can open selected text from a web page directly in AccelaReader, avoiding manual copying. It runs on the web and is listed with a Chrome extension. AccelaReader has a free plan and no comprehension exercises or guided training. Support is listed through Iris Reading by email and telephone.

Ledor is a free, open-source reader for RSVP, EPUB files, and web articles, available on Android, iOS, Linux, and the web. It offers RSVP, text-to-speech narration, and a traditional e-reader mode. Readers can import EPUBs or save articles by URL; Android users can also share a page with the app. Text-to-speech uses system voices, provides lock-screen controls, and supports speeds from 0.5× to 3×. Appearance settings cover colors, fonts, sizes, and positions, with light and dark themes and a live preview.

Ledor works offline, storing books and progress on the device. Optional Google Drive sync can carry the library, progress, bookmarks, ratings, sessions, and display settings across devices. The privacy policy says the app collects no data and has no analytics, ads, tracking, accounts, or servers of its own. Weekly and monthly reading charts and a shareable monthly recap are calculated on the device. The MIT-licensed free plan includes all features, with no ads or account required.
