LemonSlice
ReivindicarLemonSlice is an AI video avatar platform that creates real-time, interactive video avatars from a single photo. It is built for voice and video agent workflows that need synced avatar video on top of an existing or managed speech stack.
Overview
LemonSlice is an AI video avatar platform that generates real-time, interactive video avatars from a single photo. The product is designed for voice and video agent applications, where synced avatar video needs to run alongside speech and conversation in a live session.
The docs describe LemonSlice as a video layer that can sit on top of an existing agent stack. Depending on the setup, you can keep your own STT, LLM, and TTS, use a no-code widget, or let LemonSlice manage more of the pipeline while the avatar video is streamed over WebRTC.
Features
Fits different agent architectures
Use LemonSlice with your existing STT, LLM, and TTS stack, or let LemonSlice manage the speech and intelligence layer in hosted and widget options.
Multiple deployment modes
Support no-code avatar embeds through a widget, or build a custom call experience with the self-managed or hosted pipeline options.
LiveKit and Pipecat integration
Connect with LiveKit or Pipecat when you want LemonSlice to sit on top of an existing voice agent stack.
Avatar creation workflows
Use any image as an avatar in the self-managed pipeline, or design avatars in the web app for the widget and hosted pipeline options.
Documentation-driven setup
Start from the docs, where LemonSlice positions itself as a video layer for voice and video agent applications and links to reference and integration pages.
Use cases
Augment an existing voice agent
A product team can add a talking avatar to a customer-facing assistant without rebuilding its existing speech or language stack, using LemonSlice as the video layer on top of current STT, LLM, and TTS components.
Embed an avatar on a website
A website team can embed a prebuilt widget for a no-code avatar experience when it wants an on-site conversational interface without standing up a backend.
Build a custom agent stack
A developer can connect LemonSlice to LiveKit or Pipecat to keep a custom call experience while adding synced avatar video to the session.
Use a hosted pipeline
A team can use the hosted pipeline when it wants LemonSlice to handle STT, LLM, and TTS while the frontend stays in a Daily room–based call experience.
Create an avatar from a photo
A user can start from a single image and turn it into an interactive avatar for demos, assistants, or other live conversational experiences.
