Dyslexia affects how the brain processes written language, making reading a daily challenge for millions. But most people have no idea what those struggles actually feel like. That’s where simulation tools come in—they let you step into the shoes of a dyslexic reader, transforming text into a swirling, jumping, letter-flipping experience. These aren’t just educational; they’re eye-opening. If you’ve ever wondered why certain fonts or layouts help, or you’re designing content for dyslexic audiences, this list is your gateway. Below are 17 websites and tools that simulate or address dyslexia, from the exact one you saw on that pin to practical alternatives for empathy and design.

Why Simulating Dyslexia Matters More Than You Think
Most of us take reading for granted—the letters stay put, words flow, and meaning comes easily. But for dyslexic readers, the experience is often chaotic: letters swap, jump, and blur, making even simple sentences a puzzle. Simulation tools bridge the empathy gap, letting designers, educators, and friends understand these challenges firsthand. They also help dyslexic individuals find tools that ease their reading. By exploring these simulations, you’ll gain a deeper appreciation for accessible design and maybe even discover a new perspective on how we communicate.
