It works offline. Always.
Everything you rely on to speak lives on your device. No server, no sign-up, no signal — the board still talks.
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.
Built on three promises
Your words, exactly.
Suggestions only ever propose — the app never speaks anything you didn't select. What you choose is what it says.
Free means free.
Open source under the MIT license. No paywalled voices, no premium tiers, no trial that expires. Forever.
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. Boards are operable by touch, switch scanning, dwell, and camera-based gaze, and everything imports and exports the Open Board Format so your work is never locked in.
