There are plenty of browser extensions that promise to improve readability. So why should you choose FocusFlow? In this post, we'll break down the features and principles that set FocusFlow apart from every other accessibility tool in the Chrome Web Store.
Built for Real Readers, Not Checkboxes
Many accessibility tools feel like afterthoughts — a single toggle that switches the font and calls it a day. FocusFlow is different. Every feature was designed based on how people actually read on the web, with careful attention to the challenges faced by users with dyslexia, ADHD, low vision, and other reading difficulties.
What Makes FocusFlow Unique
1. Multiple Dyslexia-Friendly Fonts
Most accessibility extensions offer one font — usually OpenDyslexic. FocusFlow gives you multiple font options so you can find the one that works best for your eyes and reading style. Different readers respond to different typefaces, and FocusFlow respects that.
2. Complete Typography Control
Beyond fonts, FocusFlow lets you fine-tune font size, line height, letter spacing, and word spacing using simple sliders. This level of control means you can adapt any website to your exact reading comfort — not just swap one font for another.
3. Color Overlays That Actually Help
Color overlays are a proven technique for reducing visual stress, particularly for readers with Irlen Syndrome or scotopic sensitivity. FocusFlow includes customizable color overlays with adjustable opacity, so you can find the exact tint that makes text easier to read without washing out the page.
4. Spotlight Focus Line
For readers with ADHD or anyone who struggles to track lines across wide paragraphs, the Spotlight Focus Line dims everything except the area around your cursor. It creates a focused reading zone that moves with you, dramatically reducing distractions.
5. Reading Ruler
The Reading Ruler adds a horizontal colored guide that follows your mouse. It's a simple but powerful tool for keeping your place in dense text blocks, research papers, and long-form articles.

6. Per-Site Controls
Not every website needs the font enabled. FocusFlow remembers whether the font is on or off per website, so you can keep it active on your favorite reading sites and disabled everywhere else. It's automatic — toggle once, and FocusFlow remembers your choice.
7. Profiles and Presets
Save your favorite configurations as named profiles and switch between them instantly. One profile for academic reading, another for casual browsing, a third for work emails — whatever works for your routine.
8. Keyboard Shortcuts
Power users can control FocusFlow entirely from the keyboard — no need to open the popup menu.
- Toggle font on/off: Option + Shift + F (Mac) · Alt + Shift + F (Windows/ChromeOS)
- Increase font size: Option + Shift + ↑ (Mac) · Alt + Shift + ↑ (Windows/ChromeOS)
- Decrease font size: Option + Shift + ↓ (Mac) · Alt + Shift + ↓ (Windows/ChromeOS)
9. 100% Private — Zero Data Collection
This is the big one. FocusFlow stores everything locally in your browser. No accounts. No analytics. No tracking. No network requests. Your reading habits are nobody's business but yours. Read more about our privacy-first approach.
10. Light and Dark Themes
The FocusFlow interface matches your preference with built-in Light and Dark mode support. A small detail, but one that makes the extension feel native to your browser.
Who Is FocusFlow For?
FocusFlow is designed for anyone who wants a better reading experience on the web:
- People with dyslexia who need specialized fonts and spacing adjustments
- Readers with ADHD who benefit from focus tools like the spotlight line and reading ruler
- Users with visual stress or Irlen Syndrome who rely on color overlays
