Deploy in minutes with a few lines of embed code. Photorealism, emotion, and scale for just $0.06 per minute.\n\nWe’re [@Kaahan Radia](https://bookface.ycombinator.com/user/569532) and [@Parth Radia](https://bookface.ycombinator.com/user/3206626) from Keyframe Labs. Our interactive video models bring your AI agents and applications to life.\n\n\u003chttps://youtu.be/cIEP8OwTD4M\u003e\n\nYou can try a video call for yourself here: \u003chttps://keyframelabs.com\u003e. To get a sense for the interactivity and expressive range, try asking for a sad Shakespearean monologue. Or for a “funny” dad joke.\n\n**But why video agents?**\n\n![uploaded image](/media/?type=post\u0026id=99738\u0026key=user_uploads/3206626/ad0420da-db57-4562-a1a4-b5db0b0de005)\n\nFace-to-face interaction triggers responses that text and voice simply can’t. Video calls close more deals, language learning with video tutors outperforms audio-only, and human presence drives outcomes in high-stakes interactions (e.g., telehealth, tax prep).\n\nNow that voice has emerged as a primary conversational interface across industries, video is the next leap. Developers and enterprises already use Keyframe to easily deploy photoreal, conversational humans to a wide variety of use cases, including:\n\n* AI roleplay, for corporate training / learning and development\n* AI recruiting, for interview practice and automated screenings\n* Telehealth\n* High-touch customer support\n* AI sales and customer success reps\n* Always-on digital twins of influencers, to scale engagement and hyper-personalize interactions\n\n**How it works**\n\n![uploaded image](/media/?type=post\u0026id=99738\u0026key=user_uploads/3206626/34f670bd-7436-48e9-bd72-2d0f8bd73e44)\n\nSuper simple.\n\n1. Connect your agent or LLM, or choose from our supported providers\n2. Select a persona from our stock library\n3. Drop the embed code into your application\n\nNeed a custom persona or more control? Custom personas are available on enterprise plans, and our SDKs let you roll your own implementation.\n\n**Why Keyframe**\n\nOur research goals from day one have been:\n\n* Make meaningful progress towards beating the uncanny valley\n* Run at real-time, with world-scale efficiency\n\nThe result:\n\n* Industry-leading realism and concurrency limits\n* At a fraction of the cost of competitors\n\n**Get up and running**\n\n* [Sign up free](https://platform.keyframelabs.com/) (no credit card required) and build something cool\n* Have a use case?
