Developer builds free offline AAC app for non-verbal autistic child

A developer built a free, open-source augmentative and alternative communication (AAC) app called 'Mes mots' for a specific non-verbal autistic child who cannot yet read. The app uses a touchable tile grid that speaks words aloud, with tiles that never reorganize so the child can learn by finger position rather than text. Built with Vue 3 and TypeScript over several weeks, the app stores all data — including family photos and recorded voices — locally on the device using IndexedDB, with no server, no account, and no data transmission. Users can back up their data manually in the Open Board Format (.obz), an open standard compatible with other AAC tools, and the app works fully offline as a Progressive Web App. While professional AAC apps like Proloquo2Go and Grid 3 already exist, the developer aimed to create a simpler, immediately usable solution tailored to one child's specific needs.
