TL;DR

Create cinema that feels real. Koyal captures emotional tone from your audio, turning emotion into cinematic scenes with consistent characters and settings. You can storyboard, direct, and edit every scene to perfection.

The Problem

Filmmakers, musicians, and creators spend weeks to months scripting, shooting, and editing or pay $100,000+ to agencies to get something that feels right.

Even with new AI tools, you’re still wrestling with prompting, uncanny performances, and inconsistent characters.

The Solution

Koyal lets you speak your story once, and watch it come to life.
We capture the emotional tone in your voice or script and translate it into expressive, cinematic performances with consistent characters, settings and storylines.

You can storyboard, reshoot, and refine each scene naturally, like directing your own crew: no complex prompts, no model wrangling, no editors needed.

Just your voice, your script, and your vision.

How Koyal Works

Demo Video

  • Upload your script or record your voiceover: Koyal understands the emotion, pacing, and intent behind every line.

  • Design your characters: Create an AI character or safely place yourself in the film using CHARCHA: our Character Captcha protocol that ensures your likeness is used with verified consent.

  • Auto-generate cinematic scenes: complete with consistent characters, environments, and shot logic.

  • Storyboard and edit visually: adjust lighting, camera angle, or emotion directly with simple directions like “make it more hopeful” or “change the setting to night.”

  • Export your finished film: ready to share across YouTube, socials, or investor decks.

In Action

We’ve battle-tested Koyal across music, media, and startups.

  • Worked with Universal Music, T-Series, and major Bollywood studios.
  • Created videos for Grammy and Oscar-winning artists like A.R. Rahman, Ricky Kej, and Shankar Mahadevan, each crossing 1.5M+ views.
  • Partnered with 22 YC companies to create their launch videos in days, not weeks.

Who We Are

We’re Mehul and Gauri Agarwal, a brother-sister team obsessed with reimagining how stories are told.

We are a team from MIT, CMU and Meta with experience building in AI video. Koyal evolved directly from our research published at Neurips 2024.

The Future of Filmmaking

Koyal is inspired by how Pixar builds stories : audio first, visuals second.
We aim to replace the camera with intelligent AI systems that understand how to translate human intent into cinematic storytelling.

You no longer need cameras, expensive sets and set pieces, or prompts: just your voice and imagination.
