Koyal turns any audio into end to end cinematic video in one go, with consistent settings, storylines and characters (including you). Unlike working directly with raw models and getting AI video slop, Koyal handles all the complexity agentically so you can focus on your story. You no longer need a camera to create a film.

Most people speak more than they type, and we experience the world in motion, not still images. So while everyone was focused on text-to-image, we asked a simpler question: what if audio becomes the primary interface for creating video? That idea led to Koyal. Before this, I bootstrapped a text-to-3D startup working with major game studios (which taught me very quickly why GTA 6 takes a decade). Meanwhile, my sister Gauri left big tech (Instagram video) to research video generation at MIT Media Lab. We realized we had converged on the same niche and did a NeurIPS paper on this. Koyal is inspired by how Pixar films are made: record the voice first, then craft visuals around emotion and pacing. Instead of hundreds of animators doing that by hand, we built AI systems that translate vocal expression directly into visual storytelling. And yes, it works for live action too.

@agarwalml Fresh take on auto-0generated visual content. Nice work!

Mehul Agarwal

@osakasaul thanks, the aim is to actually meet filmmakers where they are with AI

Gauri Agarwal

@osakasaul Glad you liked the idea, our idea is not to build an answer machine that gives you an output, but to build an interactive tool that fosters more creativity.

@agarwalml Blown away by the demo video!

Gauri Agarwal

@himani_sah1 Thanks! Our stack is fully agentic and we work with over 30+ SOTA models but use them intelligently to get the best prompt adherence and consistency in our scenes.

Would love for you to give it try!

Mehul Agarwal

@himani_sah1 thank you so much!!

Congrats on the launch @agarwalml @agarwal_gauri !!

Mehul Agarwal

@agarwal_gauri  @suvrat thanks for inspiring us to get started on this journey!

Gauri Agarwal

@suvrat Literally could not have done it without your support and guidance! Thank you for being our Day -1 supporter!

Tanmay Goel
Still remember the first music video we made using Koyal! Have come so far since then! Congrats on the launch
Mehul Agarwal

@tanmay_goel1 thank you so much for being a day -1 supporter!

Gauri Agarwal

@tanmay_goel1 haha check out the V2! Maybe we can do a before and after for the same video!

Parth Sarthi

Woah, this looks really good! Any limits on how many videos I can make?

Mehul Agarwal

@parth_sarthi1 You can make 15 minutes in one sitting, but your characters once trained can be used in different generations, so feel free to go ham with multiple tabs!

Gauri Agarwal

@parth_sarthi1 15 min at a time. You can keep reusing your characters, styles and assets in all subsequent generations to create any length of content. We are already serving micro dramas and full length feature films!

Recently an ex-Pixar Animator told us they’ve been spending 6+ weeks of desk time crafting a single AI short film: prompting every shot manually, fighting for consistency, and rebuilding scenes over and over.

We felt there had to be a better way.

Koyal is an agentic AI filmmaking platform that keeps all the creative controls filmmakers:
storyboarding, costume fitting, set design, production design, but without the slow, manual prompt-by-prompt workflow.

Koyal handles the hard parts:

  • Consistent characters across an entire film

  • Consistent environments + shot coherence

  • A stable, evolving storyline

  • Fully automated scene generation (no prompting each shot)


So you can focus on directing, not debugging prompts.

If you have feedback on what we can do better, would love to hear it below!

Polman Trudo

@agarwal_gauri Loving the consistent characters across an entire film, that alone would save so much time vs rebuilding scenes shot-by-shot, def curious to try.

Gauri Agarwal

@polman_trudo Absolutely. You can try it for free at beta.koyal.ai

Congrats on the launch @agarwalml and @agarwal_gauri!!

I have worked with Mehul personally on a few projects, and can vouch for his utmost commitment to building a quality product. I'm super glad to see Koyal grow from its earlier stages, to the refined videos it produces now! I'm sure if it follows this trajectory it's gonna produce immense value for filmmakers and content creators.

All the very best, I'm betting on you guys!

@plibither8 thanks for the kind words! It's always the support from people in our corner, people like you, that helps motivate us to constantly improve

Interesting. I got another idea. To create a YouTube video tutorial from the prompts. I usually learn best from the video, but ChatGPT and other tools create only text guidance. What about creating the video guidance?

Gauri Agarwal

@busmark_w_nika Great idea! Will keep this in mind for the next launch. Meanwhile taking a audio lecture/ podcast from a source and visualizing it will also work!
