**A proof-of-concept tutoring app for students learning math.** Using the phone camera,
the app sees and understands math problems, guiding students through problems with hints
and step-by-step questions. We added text-to-speech (TTS) to give our app a voice, further
engaging students and making it feel like a more personal experience.
I built the app using SwiftUI. using AVFoundation for video recording and TTS playback.
[Tri Vu](https://www.linkedin.com/in/tri-q-vu/) built a web interface prototype and Python-based
backend utilizing the Gemini Vision API and Fish Audio for TTS.
