An honest look at Zeek, AccelaReader, Spreeder, SwiftRead, and Sprint Reader — who they're built for, what they cost, and where each one falls short.
AccelaReader is the incumbent — simple, free, and reliable. Spreeder is the premium option with training drills ($67). Zeek is the free alternative built for accessibility — ORP highlighting, camera OCR, and a UI designed specifically for dyslexia and ADHD readers. SwiftRead and Sprint Reader are solid Chrome extensions for reading web pages in-browser.
Most people discover RSVP reading through AccelaReader — it's been the top Google result for years. But users often start looking for alternatives because of a few recurring frustrations:
Copy-paste workflow. AccelaReader requires you to paste text into the tool manually. There's no camera scanner, no file import, and no browser extension to read content in-place.
No accessibility focus. None of the original RSVP readers were designed for dyslexia or ADHD. They're speed-reading tools first, accessibility tools second (if at all).
Dated interfaces. Many of these tools were built years ago and haven't been updated. The UI can feel cluttered or hard to use on mobile devices.
Pricing. Premium tools like Spreeder charge $67+ for features that many users don't need. Free alternatives exist, but the quality varies widely.
Not all RSVP readers are equal. Here are the criteria that matter most when choosing one:
ORP (Optimal Recognition Point) highlighting — the letter where your eye naturally fixates for fastest word recognition. Tools that highlight this letter reduce cognitive load per word.
Speed adjustability — you need fine control over WPM, ideally adjustable while reading (not just before you start).
Input flexibility — can you only paste text, or can you also scan printed documents, import files, or read web content directly?
Accessibility design — high contrast, distraction-free layout, and features specifically for dyslexia/ADHD readers.
Mobile support — responsive design, touch gestures, and portrait reading mode matter if you read on your phone.
Privacy — does your text stay on your device, or is it sent to a server?

Zeek is a free, browser-based RSVP speed reader designed from the ground up for readers with dyslexia, ADHD, and visual processing differences. It features ORP (Optimal Recognition Point) letter highlighting, a built-in camera OCR scanner powered by Tesseract.js, and a distraction-free dark interface.
The speed dial adjusts WPM in real time while reading (no need to pause). Mobile support includes swipe gestures and a portrait reading mode with a word queue. All text processing happens locally in the browser — nothing is sent to any server.
AccelaReader is the longest-standing free RSVP reader on the web. It offers a simple paste-and-read workflow with granular controls for chunk size, speed variability, stopword skipping, and sentence pausing. It's backed by Iris Reading, a well-known speed reading education company.
The interface is functional but dated, and hasn't seen significant updates in recent years. There's no mobile optimization, no ORP highlighting, and no way to input text beyond copy-paste. But it remains reliable and fast for basic RSVP reading.
Spreeder is the premium option in the RSVP reader space. Beyond basic RSVP reading, it includes structured speed reading training with expert-designed drills, warm-up exercises, a built-in dictionary, vocabulary flashcards, and cross-device progress tracking. It supports 52 file formats including ePub and PDF.
The $67 lifetime price is reasonable for serious speed readers who want a structured curriculum. But for casual users who just need to read text faster, the free alternatives cover the core RSVP functionality.
SwiftRead is a browser extension that lets you speed-read any text on the web without leaving the page. Highlight text, right-click, and it opens an RSVP overlay. It also supports PDFs, ePub files, Google Docs, and Kindle Cloud Reader content.
The free tier covers basic RSVP reading. The paid PRO version adds advanced customization. The main limitation is that it's a browser extension, not a standalone tool — it requires Chrome or Edge, and doesn't work on mobile browsers.
Sprint Reader is a free Chrome extension for RSVP speed reading. Select text on any webpage, right-click, and read it word-by-word in a popup. It includes optimal letter highlighting, multiple color schemes, automatic language detection, and adjustable font sizes.
It's the most lightweight option — focused purely on the reading experience with no extras. The trade-off is that it's Chrome-only and has no standalone web interface.
The right tool depends on what you need. Here's a quick decision guide:
Zeek — designed specifically for accessibility with ORP highlighting and distraction-free UI.
Zeek or AccelaReader — both free, no account needed, paste text and go.
Spreeder — the only option with structured drills, progress tracking, and expert content.
SwiftRead or Sprint Reader — browser extensions that let you speed-read any webpage without copy-pasting.
Zeek — the only RSVP reader with built-in camera OCR.
Zeek or Spreeder — both work on mobile. Zeek is free; Spreeder is paid.
Zeek and AccelaReader are both free web-based RSVP readers. Zeek stands out with ORP highlighting, camera OCR scanning, and accessibility features designed for dyslexia and ADHD. AccelaReader offers more granular speed controls and chunk-size options. Both are completely free with no account required.
Zeek is the closest free alternative to AccelaReader. It offers similar RSVP functionality with added features like ORP letter highlighting, camera-based OCR text scanning, mobile gesture controls, and accessibility-first design for dyslexia and ADHD readers. Other alternatives include SwiftRead (Chrome extension) and Sprint Reader (Chrome extension).
Spreeder ($67 lifetime) is worth it if you want structured speed reading training with drills, progress tracking, and multi-format file support. If you just need a simple RSVP reader to paste text and read, free tools like Zeek or AccelaReader cover that without the cost.
Zeek is specifically designed for ADHD readers with a distraction-free dark interface, single-word focus, and adjustable speed. The fixed-point word presentation keeps attention locked to one location on screen, and the continuous motion maintains engagement naturally.
Yes, RSVP can increase reading speed by eliminating eye movement overhead and reducing subvocalization. Most users can reach 400-600 WPM after practice, compared to a natural reading speed of 200-250 WPM. However, comprehension at very high speeds (800+ WPM) may decrease, so finding your personal balance is important.
Web-based tools like Zeek work on any mobile browser. Spreeder has an iOS app. Browser extensions like SwiftRead and Sprint Reader do not work on mobile browsers. Zeek includes mobile-specific features like swipe gestures and portrait reading mode.
