Disability simulator for the web

Experience your website with a range of simulated disabilities, including color blindness and dyslexia with our free toolbar for Google Chrome.

What it does

This toolbar simulates using the web with a range of disabilities, including:

  • Dyslexia
  • Colour blindness
  • Myopia
  • Blindness & more

We've designed the tool for people looking to develop and test accessible websites, especially those meeting WCAG 2.1. It's free and it always will be.

Screen reader simulator

Screen readers can be overwhelming. We made a screen reader simulator that is as easy-to-use as possible.

  • Experience the web as if you were blind or partially-sighted
  • Optionally have text read aloud to you
  • Navigate with your keyboard or mouse
  • Optionally turn off your ability to see the page
  • Experience screen reader features like skipping to headings, landmarks, form elements, and more
Accessibility Hero

Forever free

We think accessibility is really important. So we're committed to making our toolbar free to everyone.
