CardChat vs DonKeyBoard 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.
