What is ASTI?
ASTI is an AI assistant built for people with dyslexia, by people who understand it. It doesn't assume reading is easy or that you just need to "try harder." Instead, it adapts the world's text into forms that make sense for how your brain works best.
Text‑to‑Speech
Hear emails, documents and web pages read aloud.
Dyslexia‑Friendly Fonts
Adjustable spacing and typefaces like OpenDyslexic.
Text Simplification
Complex information rewritten clearly, without losing meaning.
Voice‑to‑Text
Speak naturally, and ASTI writes for you.
Built with input from people who live with dyslexia: practical tools that actually help.
How ASTI Helps with Dyslexia
Listen instead of reading
ASTI reads everything for you: emails, documents, web pages, messages. You choose the voice, speed and style.
ASTI can also summarise before reading: “This message is from your manager about Friday’s meeting. Want to hear it?” You’re always in control.
Dyslexia‑friendly display
Customise every visual element: font, spacing, colours, background tone and line height. Make text look how your brain needs it to look.
ASTI can highlight every other line for easier tracking, or show one paragraph at a time.
Text simplification
ASTI rewrites dense or jargon‑heavy text into plain, readable English, without dumbing it down.
You get the same meaning, just clearer and faster to process. No more rereading the same sentence five times.
Writing support
Speak your thoughts, and ASTI converts them to text. It checks grammar and phrasing in a helpful (not judgemental) way.
You focus on ideas; ASTI handles the structure.

Writing support features
Voice-to-Text
Speak naturally and ASTI converts it to written text. Punctuation is added automatically. No more fighting with spelling while trying to express ideas.
Dyslexic readers often describe exhaustion, not inability. ASTI's goal is to ease that fatigue by letting you read, listen, and write in the way your brain actually prefers.
Helpful spelling check
ASTI catches typos and spelling mistakes, but presents corrections helpfully, not judgementally. "Did you mean...?" rather than just marking things wrong. You're learning, not failing.
Sentence simplification
When a sentence gets too complex or tangled, ASTI suggests clearer ways to phrase it. You communicate effectively without the stress.
Thought organisation
Brain dump everything you want to say, and ASTI helps organise it into logical structure. Ideas → organised writing, without the friction.
Frequently Asked Questions
Is ASTI only for dyslexia?
No. While this page focuses on dyslexia support, ASTI also helps with ADHD, autism, and other neurodivergent experiences. Many features (text-to-speech, simplification, voice-to-text) are useful for anyone who processes information differently.
Can ASTI help kids with dyslexia?
ASTI is designed for adults, but the features work for teens too. For younger children, parental guidance is recommended. Check out our families page for more on supporting neurodivergent children.
Does ASTI work with screen readers?
Yes! ASTI is built with accessibility in mind. It works alongside existing screen readers and assistive technologies. If you use specific tools, let us know during early access so we can ensure compatibility.
Can I customise which fonts and colours ASTI uses?
Absolutely. Every visual element is customisable: fonts, colours, spacing, line height, background overlays. ASTI saves your preferences so you never have to reconfigure. What works for your brain, every time.
How is ASTI different from just using built-in text-to-speech?
ASTI is built into your workflow. It automatically works with all your communications (email, messages, tasks) without extra steps. It also prioritises what's important, summarises before reading, and combines text‑to‑speech with simplification and organisation. It's a complete system, not just a feature.
