LemonSlice lets anyone create interactive, talking and singing AI avatar videos from a single photo. Its API and Character World Model technology let developers embed lip-synced, real-time avatar video into products, websites, or voice-agent stacks over WebRTC. Avatars can display hand gestures, emotions, full-body movement, and can be photorealistic or non-human/cartoon characters. It offers self-managed (bring-your-own LLM/TTS), hosted pipeline, and no-code widget integration options.
