Koyal

Koyal is an agentic AI filmmaking platform (Y Combinator F25) that turns a script or an audio clip - a song, a podcast, a voiceover - into a finished, personalized video with consistent characters, settings and camera work. Founded by CMU/MIT/Meta alumni siblings Mehul and Gauri Agarwal, the company follows a Pixar-style 'audio first, visuals second' approach and has run paid pilots with Universal Music, T-Series and Bollywood studios, producing music videos for artists like A.R. Rahman, Ricky Kej and Shankar Mahadevan.
