Read full description

ChirpBot is a free AAC communication assistant designed to help children and adults express themselves with confidence. Built by a parent of children with autism, with a background in psychology and data science, ChirpBot combines simple design with powerful assistive technology to make communication easier, faster, and more meaningful. What Makes ChirpBot Different Most tools focus on repetition. ChirpBot embraces curiosity. By rewarding exploration, it helps users discover new words and meanings, organizing concepts into natural communication. Instead of scripted responses, ChirpBot gently guides toward the phrases that fit the moment, encouraging progress, confidence, and genuine connection. Two Ways to Communicate Learning Mode — Step through progressive levels that build vocabulary and confidence. Each stage introduces new words and concepts, tailored to each user's pace. Communication Mode — Create personalized decks with words, images, and sounds for everyday use at home, school, work, or in therapy sessions. Switch between modes anytime for flexible, adaptive communication. Smart Suggestions ChirpBot's context-aware word engine learns from real AAC use, not from the internet. It predicts relevant words and phrases that make sense together, helping users form natural sentences without pressure.
