About Cboard
Cboard is a free, open-source, browser-based Augmentative and Alternative Communication (AAC) application designed for children and adults with speech and language impairments, including autism, cerebral palsy, and intellectual disabilities. It enables users to communicate using a grid of symbols and text-to-speech (TTS) output, supporting over 40 languages. The app works offline on Google Chrome (desktop and Android), requires no registration, and is touch-friendly for tablets and smartphones. Key features include customizable vocabulary boards, board import/export (JSON, CSV), color-coded categories, word prediction, multi-sentence construction, and a dark mode. Built with React, Cboard modernizes AAC with a clean, intuitive interface that does not rely heavily on text help. Unlike many paid AAC apps, Cboard is completely free and open-source, allowing community-driven translations and customizations. It is best suited for non-verbal individuals or those with temporary speech loss, from children to adults. While it lacks advanced eye-tracking or high-end natural language processing found in commercial alternatives like Proloquo2Go, it offers a robust, private, and accessible solution for basic to intermediate communication needs.
Behind the Verdict
Cboard fills a vital niche: a no-cost, open-source AAC tool that actually works. We'd reach for this when the user needs a straightforward symbol-based communicator without recurring costs or data privacy concerns. The lack of registration and offline support in Chrome are real wins for families on the go or in settings with spotty internet. Where it bites is customization depth and performance—editing boards can be slow, and the interface, while modern, isn't as polished as paid competitors. Compared to Proloquo2Go, Cboard lacks advanced natural language processing and robust vocabulary growth, but for a free tool, it covers the basics very well. The dark mode and typed text option are appreciated by users with light sensitivity or those who need more than symbols. That said, don't expect eye-tracking, HIPAA compliance, or phone support; this is a community-driven project best for individuals and classrooms that have someone tech-savvy to set it up. If you're a speech therapist with a tight budget, Cboard is worth trialing—just be prepared for occasional slowness during editing.
