Built Cast to solve two real problems for AI video creators:
Copyright risk — if your AI character ends up looking like a real person, you're one viral ad away from a likeness lawsuit. Legal teams can't sign off without proof the character wasn't based on anyone real. And tools like Gemini won't let you upload real people's photos anyway, for good reason.
The creativity gamble - you have a specific look in your head (a 40-year-old Korean detective in a rumpled blazer) but prompting is a dice roll. Getting the exact look you want takes expert prompt engineering and a lot of trial and error, even on free tools like Gemini.
Cast solves both. Every character is 100% AI-generated with zero real-person training data - no likeness risk, no model releases. And you don't need to be a prompt expert: browse 100+ ready-made photoreal characters or describe exactly who you need and get a fully designed character with a 4K 8-panel reference sheet in ~90 seconds.
The reference sheet works beautifully with the consistency features already built into Kling, Runway, and Veo - multi-angle references produce much better results than a single photo. Launch offer: first 200 accounts get 2 free credits. Would love to hear what you build.
