FastReadi vs LightSpeedRead

FastReadi is an iOS app that brings speed reading, lecture capture and AI study tools together. Focus mode shows one word at a time, while Bionic Reading emphasizes the beginnings of words; reading speed can be adjusted from 100 to 800 WPM. The library supports EPUB, MOBI, PDF and TXT. The app records and transcribes lectures, keeps them alongside books, and supports voice notes on books. Its book chat answers from uploaded pages and cites the passages behind replies. Study tools include AI flashcards, spaced repetition, chapter summaries, quizzes, exam planning, a Study Hub and mastery tracking. The Free plan includes reading, recording and capture, plus a weekly allowance for AI summaries, quizzes, study guides and book chat; reading features remain free without a paywall. Pro costs $39.99 a year and includes unlimited AI summaries, quizzes, study guides, flashcards, book chat and lecture transcription, along with smart notes and cloud sync. The app supports offline use after login and lists English, Spanish, French and Portuguese. Apple's listing says identifiers and usage data may be used to track users across other companies' apps and websites; Apple notes this disclosure is unverified.

LightSpeedRead is a speed-reading reader that presents words or short groups of words one at a time at a fixed point on screen using Rapid Serial Visual Presentation (RSVP). The web reader accepts pasted text, links, PDFs and EPUBs. Readers can adjust speed, pauses for long words and punctuation, gradual ramp-up, themes, fonts, emphasis and word size. A red letter marks each word’s optimal recognition point, aligned to a fixed center line. Submitting an article URL sends it to r.jina.ai to fetch and extract text; pages behind logins or paywalls may not extract cleanly. Pasted and uploaded text is processed locally in the browser, and the Chrome extension reads page text only when invoked. The free plan includes the website reader and extension reading up to 600 wpm. Pro is $2.99 per month or $19.00 per year, with speeds up to 1000 wpm and additional controls. The iOS app is marked “Coming soon.” The maker cautions that high RSVP speeds can reduce comprehension, especially for dense or important material.
