SignifyAI is an accessibility-focused Flutter application designed to bridge communication gaps for the deaf, hard-of-hearing, and neurodiverse communities. The app provides real-time speech-to-sign and sign-to-speech translation, autism support tools, and customizable gesture-based navigation.

This project was developed as part of the Youth Coders Collective Hack 2025, a global hackathon empowering young developers to create impactful solutions for social good. SignifyAI is a proud submission, showcasing innovation in accessibility, inclusivity, and user empowerment.
