Lemon Slice

What is Lemon Slice?

Lemon Slice builds real-time interactive avatars that listen, talk and respond live inside a product or website. It works with any character that has a face, including photorealistic humans, cartoons and mascots, and creates an avatar from a single image with no training or rigging.

Key capabilities of Lemon Slice

• Image-to-avatar: creates a live avatar from one image.
• Action Engine: controls expressions, hands, shoulders and posture, with actions and emotions set through the API.
• Low latency: the vendor reports 471 ms to first byte and about 2.04 seconds end to end.
• Scale: supports thousands of concurrent calls and multi-region servers.
• Zero data retention: a privacy mode that avoids storing data.
• Flexible stack: use your choice of LLM, voice provider and knowledge base.

How Lemon Slice works

You provide a character image and connect your LLM, voice and knowledge base. The avatar streams in real time through a hosted widget added with two lines of code, or through REST and WebSocket endpoints and Python and Node SDKs. Integrations include LiveKit, Pipecat, Agora and Daily.

Who uses Lemon Slice?

Developers building AI tutors, support agents, companions and sales assistants with a face use it. Teams should confirm latency under their own load and consent rules for avatars based on real people.

Lemon Slice pricing

Plans start at $8 per month, and each subscription includes monthly credits that call minutes consume. Enterprise and high-volume pricing is available through sales. You can chat with demo avatars on the homepage for free.

Lemon Slice alternatives
