CardChat vs Lighthouse AAC

CardChat is an AAC picture communication and visual schedule app designed for people with communication difficulties, including autism, language delays, Rett syndrome, aphasia, intellectual disabilities, and muscle atrophy. 【Picture communication and sentence building】 • Tap pictures to speak and combine cards into sentences, with voice cloning in Chinese and English. • Create custom categories and cards. • Use video cards, flowcharts, and picture books. 【Multiple ways to interact】 • Eye control uses the front camera and AI algorithms, with no eye-tracking device required. • Scan mode lets you confirm selections with an external switch, by patting the screen, or by blinking, making it usable even for people with very limited muscle movement. 【Visual schedules】 Show daily routines and activity steps clearly with visual schedules and full-screen alarm reminders. 【On-device English grammar correction】 In English mode, you can enable optional on-device grammar correction to refine and complete sentences built from cards. All processing happens on your device, with no upload to a server. 【Local storage and backups】 Card data is saved within the app on your device and is not automatically uploaded to the cloud. Card backups and sharing are supported.

Lighthouse AAC is a free, open-source communication app for non-speaking children. It gives a child a simple, reliable way to talk using picture buttons and clear speech on a tablet. It is built on one promise: Augment, Don't Rearrange. The buttons never move and nothing is ever hidden, so a child's muscle memory is always safe. Lighthouse gently highlights words a child is likely to want next with a soft "Golden Glow," based on time of day and recent taps. It suggests; it never insists, and it never rearranges the grid. Why families and educators choose Lighthouse: - Completely free. No ads, no subscriptions, no in-app purchases. - Works on-device. No account, no sign-in, and nothing your child says or taps ever leaves the device. - A sentence bar lets a child build and replay phrases with natural-sounding speech. - Parents and therapists can add custom buttons and photos, and record a familiar voice, all behind a simple math gate that keeps young children out of the settings. - Available in multiple languages. - Designed with input from a Board Certified Behavior Analyst. Lighthouse is the flagship product of the Kinder Horizon Foundation, a non-profit society. Our goal is simple: every non-speaking child deserves a voice, free of charge. Lighthouse is a communication tool, not a medical device, and does not provide medical advice or treatment.
