Ledor review
A free, offline-first speed reader with strong import and text-to-speech options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ledor is an open-source speed-reading and e-reading application for people who want to read EPUB files and web articles across web, Linux, iOS, and Android. Its main mode uses Rapid Serial Visual Presentation (RSVP), displaying one word at a time with Optimal Recognition Point highlighting. Continuous e-reader mode and text-to-speech with word-synchronized highlighting give readers alternatives to the primary RSVP experience. The product is particularly suited to readers who value offline storage, local progress data, and an open-source application rather than a subscription service.
Content handling is one of Ledor's clearest strengths. EPUB import supports book-based reading, while web articles can be added by URL or through the Android share sheet. Offline-first local storage keeps books and reading progress available without relying on a connection. Bookmarks include context snippets, and reading statistics show WPM trends, giving readers ways to revisit passages and monitor pace over time. Optional Google Drive synchronization adds a cloud-based route for keeping data aligned, while the interactive RSVP demo provides a way to view the core reading approach before committing to the app.
Ledor is free and has no paid tiers to compare, which keeps access straightforward. Its platform footprint is broader than a single-device reader, but iOS use requires building from source, and the product's focus remains speed reading rather than a comprehensive comprehension-training system. Readers seeking EPUB and web imports, offline access, synchronized text-to-speech, and open-source availability should consider Ledor. Those who need verified comprehension exercises or a ready-to-install iOS release should choose an alternative.
