LemonSlice
Give your voice agents a face
LemonSlice is an AI research lab and platform that creates interactive, real-time AI avatars from any image. Its proprietary Character World Model generates every frame on the fly, enabling avatars that listen, talk, and respond with natural lip sync, facial expressions, and body language. The platform is API-first and designed for developers to integrate into websites, apps, or physical kiosks.
The platform offers several models, including LemonSlice-2.1, a 20-billion parameter model, and Character World Model-1, which adds controllable actions and emotions. It supports integration with major language models and voice providers such as OpenAI, Claude, ElevenLabs, and Cartesia. Deployment options include a hosted widget, a self-managed pipeline, and API access. Features include unlimited custom avatars, image-to-avatar creation, real-time image updates, green screen compositing, and support for non-human characters.
LemonSlice is aimed at developers and businesses building conversational AI experiences for education, entertainment, physical installations, and customer support. It offers a free plan for browsing featured avatars, and paid plans starting with a Starter tier. Pricing is subscription-based with monthly credits; minutes are deducted from the credit pool, with overage billing available. Enterprise plans include team accounts, data residency options, and dedicated support.
