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

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