PageSpeak — Dyslexia-First Reading Extension for Chrome

1 in 5 People Struggle to Read the Web

Dyslexia affects 15–20% of the population. Dense paragraphs, tiny fonts, and walls of unformatted text make everyday reading exhausting. PageSpeak transforms any webpage or PDF into a reading-friendly environment — backed by decades of reading research.

Research-Backed Reading Tools

Every feature in PageSpeak is grounded in peer-reviewed reading and dyslexia research. These are not gimmicks — they are evidence-based interventions.

Visual Reading Aids

Dyslexia-Friendly Fonts

Switch any webpage to OpenDyslexic, Atkinson Hyperlegible (by the Braille Institute), or Lexend — each designed to improve letter recognition and reduce visual confusion.

Shaver-Troup et al., "Lexend: A Variable Font Empirically Optimized for Reading"

Letter & Line Spacing

Widen letter and line spacing across any page. Extra-large letter spacing is the single most research-backed intervention for improving reading speed in dyslexia.

Zorzi et al., "Extra-large letter spacing improves reading in dyslexia," PNAS 2012

Color Overlays

Apply a tinted overlay to reduce visual stress and glare. Choose from five colors with adjustable opacity. Supports individuals with Irlen Syndrome and scotopic sensitivity.

Irlen, H., "Reading by the Colors" (1991)

Word-by-Word Tracking

Each word highlights in real time as the voice reads it. Visual anchoring reduces line-skipping and helps readers maintain their place. Choose from six highlight colors.

Focus Lens

A fixed bar at the top of the screen shows the current sentence in large, clear text. Reduces cognitive load by isolating what matters right now. Four size options.

Distraction Dimming

Dims everything on the page except the paragraph being read. Removes visual noise so you can focus on one thing at a time.

Reading Ruler

A horizontal guide line follows your cursor to help you track which line you are reading. A simple, proven aid used in classrooms for decades.

Text-to-Speech

TTS with Word Sync

Hear any text read aloud while each word highlights in sync. Combining auditory and visual input (dual coding) dramatically improves comprehension and retention.

Paivio, A., "Dual Coding Theory" (1986)

Voice, Speed & Pitch

Choose from all voices installed on your system. Adjust speed from 0.5x to 3x, fine-tune pitch, and set volume. Every reader is different — personalize it.

Built-In PDF Reader

Right-click any PDF link to open it in PageSpeak's reader. Text is extracted automatically so you can read PDFs aloud with all the same tracking and focus tools.

AI Comprehension

Simplify, Summarize, Explain

One-click AI actions that break down complex text. Get bullet-point summaries, simplified vocabulary, key terms with definitions, or an explanation written for a 10-year-old.

Frequently Asked Questions

How much does PageSpeak cost?

PageSpeak is $8/month. Every new user gets a full 7-day free trial with access to every feature. No credit card is required to start your trial. You can cancel anytime.

What happens after the free trial?

After 7 days, all features are locked until you subscribe. Your settings and reading statistics are preserved, so when you subscribe, everything picks up right where you left off.

Does PageSpeak collect my data?

In Offline mode, PageSpeak sends zero data anywhere. In Local AI mode, text is processed by Ollama on your own computer. In Cloud AI mode, text is sent encrypted to Claude's API. PageSpeak never tracks you, never sells data, and never phones home. Your API keys are stored in memory only and cleared when Chrome restarts.

What is Ollama?

Ollama is a free, open-source tool that runs AI models directly on your computer. When you use PageSpeak's Local AI mode with Ollama, your text never leaves your machine. It's completely private and free to use.

Does it work on PDFs?

Yes. Right-click any PDF link and choose "Open PDF in PageSpeak Reader." PageSpeak extracts the text and lets you read it aloud with word tracking, focus lens, and all other tools. Scanned PDFs (image-only) will require OCR, which is coming in a future update.

What fonts are included?

PageSpeak includes three dyslexia-friendly fonts: OpenDyslexic (heavier letterforms for character differentiation), Atkinson Hyperlegible (designed by the Braille Institute for maximum legibility), and Lexend (empirically optimized for reading fluency by researcher Bonnie Shaver-Troup). All three are bundled locally — no internet required.

Is PageSpeak open source?

Yes. PageSpeak is fully open source under the MIT License. You can read every line of code, audit the security layers, and contribute on GitHub.

What browsers are supported?

PageSpeak works on Chrome 120 and newer, as well as Chromium-based browsers like Edge, Brave, and Arc. Firefox and Safari support is not currently available.
