Personal Voice

Speak in your own voice.

On iOS 17+, AEIOU reads in the voice you trained yourself.

Blink to select

Speak with a blink.

A single deliberate blink fires the highlighted key. Built on ARKit. On-device.

Privacy

Quiet by design.

No accounts. No tracking. No data sold. Ever.

Our mission

Apps that help people access the world.

Too many tools for people with disabilities feel like an afterthought. Chardie builds the opposite — software that feels like it was made for the person using it, because it was.

On-device by default

Your words, your voice, your patterns — they stay on your phone. No accounts, no servers, no tracking.

Fast and intelligent

Predictions that learn how you actually communicate. Tap, blink, or scan to speak — whatever works for you.

Free where it counts

Communication tools should not be a luxury. AEIOU is free on the App Store.

Designed for real life

Built with input from people who use AAC, work in care, and live with disability every day.

Bespoke development

Made for one person at a time.

Off-the-shelf rarely fits. If you're supporting someone whose needs are specific — at home, in school, or in care — Chardie can design and build an iOS app shaped around them.
