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 lets you communicate via a grid of symbols with text-to-speech (TTS) output, supporting over 40 languages. The app works offline in Google Chrome on desktop and Android, needs no registration, and is touch-friendly for tablets and smartphones. Core features include customizable vocabulary boards, board import/export (JSON, CSV), color-coded categories, word prediction, multi-sentence construction, and 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, enabling 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 unique niche in the AAC space: it's free, open-source, and runs in the browser, which makes it immediately accessible to anyone with a device and an internet connection. The fact that it's free and community-driven means there's no vendor lock-in and you can customize the code if you have the technical skills. The offline mode in Chrome is a practical feature for users in areas with unreliable connectivity. However, the symbol library is not as comprehensive as paid alternatives, and the lack of advanced access methods like eye-tracking limits its use for individuals with severe motor impairments. Additionally, as a web app, it requires a modern browser and initial online setup. For speech therapists, special education teachers, and families looking for a no-cost AAC solution with multilingual support, Cboard is a strong choice. But if you need a robust symbol library, eye-tracking, or HIPAA-compliant hosting, you'll need to consider commercial options.
