A visual, AI-guided way to learn Indian classical music.
beSur is an AI-guided harmonium companion built for Marva AI LLP, aimed at Hindustani classical vocal students practicing between guru sessions.
Off-the-shelf audio libraries couldn't hit the timing precision raga practice demands, and most practice apps treat it like a generic metronome rather than the structured, raga-driven discipline it actually is — so a purpose-built engine was the only real option.
What went into it
Single Flutter codebase
One Dart codebase shipped pixel-perfect, 60fps experiences to both iOS and Android, halving build time without losing native feel.
Purpose-built audio engine
A custom real-time engine handles harmonium synthesis and tanpura drone playback at sub-millisecond latency.
Notation you can feel
Every swar lights up and every raga unfolds visually, turning traditional notation into a touch-first practice experience.
