Everyone deserves a voice. This one is free.
Public AAC is a free, open-source communication app: symbol and text boards with text-to-speech that work fully offline. No account, no subscription, no internet required to speak.

The same free app on every one of them: open it in the browser or install it like an app, and it keeps working with no internet.
What it is
A communication board: a grid of words and symbols that speaks when tapped, for people who can't rely on their own speech. A parent, a therapist, or the person themselves can set it up in a few minutes, and anything can be changed later. If you're new to AAC, the core words guide explains how these boards are usually laid out.
What it costs
Nothing. It's open source under the MIT license, with no trial, no premium tier, and no paid voices. Anyone can read the code and verify that.
Who it's for
People with ALS/MND, cerebral palsy, autism, aphasia, or recovering from stroke, and the families, speech-language pathologists, and educators who set up boards for them. The same boards work by touch, switch scanning, dwell, and camera-based gaze, so the setup carries over as someone's needs change.
A few things worth knowing
- After the first load it works with no internet at all; everything lives on the device.
- Boards are ordinary OBF files. You can export them anytime and open them in other AAC apps.
- An account is optional. It exists only to sync and share boards between devices, end-to-end encrypted (what leaves your device).
