Lemon Slice

Overview

Lemon Slice is a browser-based AI tool that turns a photo, text, or audio into talking or singing videos with lifelike characters. It’s meant for stuff like marketing, teaching, entertainment, and storytelling. The system focuses on clean lip sync, detailed motion, and multi-character scenes.

In December 2025, they launched Lemon Slice-2, calling it the first interactive AI video model that gives faces to voice agents. You only need one photo. It adds full-body movement and hand gestures to any face or style. It’s offered as an API or widget for use in other tools. 👉 Try a Pikachu one by this link. 

Under the hood, it runs on a 20-billion parameter video transformer that can stream 20fps on one GPU. It can make long videos without building up errors.

You can talk to demo characters on their site or add one to your own. Some use cases already out there:
→ Support agents who show where to click
→ Sales agents who chat instead of forms
→ Shopping helpers who try on clothes and suggest things

The point is, faces grab attention. Now, companies can have a digital face that works all day.

The developers teamed up with ElevenLabs, TryDaily, and Modal to build it. The company used to be Infinity AI, but they changed the name to Lemon Slice in 2025. Still doing the same thing - making character videos simple for anyone to use.

Main tools include:

AI Video Generation. Turn a single photo into talking or singing video. Characters can show emotions and speak over 32 languages.

Voice & Audio. Pick from built-in voices, use your own voice, or upload audio. Text-to-speech is part of it.

Creative Studio. Type in a script and get a synced video with captions and motion. Can handle more than one character.

Developer API. Real-time or batch video streaming with REST API or WebSockets.

Improved Models. Newer versions like V2.5 and V2.7 add smoother motion and subtle movements.

Other Features. Paid users get commercial rights. It also does singing avatars better than most.

Monthly and Annual plans exist, including custon priccing for enterprise customers.

Starter plan at $8, 1000 credits. 1-minute videos, unlimited agents, commercial rights.

Credits are used as you create and usually don’t carry over.
