LemonSlice

LemonSlice (formerly Infinity AI) is a frontier AI platform that transforms traditional one-way video into real-time, two-way interactive experiences using its 20B-parameter LemonSlice-2 video diffusion model.

With zero-shot capability, it turns a single image—photo, cartoon, or stylized character—into a live AI avatar that streams at 25 FPS with under three seconds of latency, enabling natural “video call” conversations via voice or text. The platform offers website video agent widgets that boost engagement and conversions, a creative studio for lip-synced videos, AI-generated music, and multi-character scenes, plus advanced customization like voice cloning, multilingual support, and API integrations.

Designed for use cases across education, customer support, sales, and corporate training, LemonSlice combines real-time performance, flexible deployment, and built-in safety guardrails to help businesses and creators humanize digital interactions at scale.

LemonSlice: The Future of Interactive Video and Real-Time AI Avatars

In the rapidly evolving world of artificial intelligence, video has long been a “one-way” medium. We watch it, but we don’t talk to it. LemonSlice (formerly Infinity AI) is changing that narrative by introducing the world’s first production-ready, real-time interactive video agents.

Whether you are a marketer, a software developer, or an educator, LemonSlice offers a revolutionary way to give your AI a face, a voice, and a personality. This article explores everything you need to know about using LemonSlice to transform passive content into engaging, two-way conversations.

What is LemonSlice?

LemonSlice is a frontier AI research and product lab that specializes in interactive video. While many AI tools can generate a video of a person talking after a few minutes of processing, LemonSlice does it in real-time.

Using their proprietary LemonSlice-2 model, the platform allows users to turn a single image—whether it’s a photorealistic headshot, a cartoon mascot, or even a Renaissance painting—into a live, conversational video agent that responds instantly to voice or text input.

The Core Technology: LemonSlice-2

At the heart of the platform is the LemonSlice-2 model, a 20-billion parameter video diffusion transformer. Unlike traditional models that require hours of training on a specific person’s face, LemonSlice-2 is zero-shot. This means:

• No Video Training Required: You only need one photo.
• Real-Time Streaming: It generates video at 25 frames per second, allowing for a “video call” experience with an AI.
• Ultra-Low Latency: With an average response time of under 3 seconds, the interaction feels natural and fluid.
• Infinite Length: Because it is an auto-regressive model, the avatar can talk for as long as needed without losing quality or “drifting.”

Key Features for AI Users

1. Interactive Video Agents (Website Widgets)

One of the most popular uses for LemonSlice is the Video Agent Widget. You can add a small bubble to your website (similar to a chatbot) that features a live, talking avatar.

• Multi-Modal: Users can type questions or speak directly to the avatar.
• Brand Ambassadors: Instead of a text-based bot, customers interact with a face that represents your brand.
• High Engagement: Early data shows that websites using video agents see up to 4x higher conversion rates compared to traditional text-only chat.

2. Creative Studio for Content Creators

For those who want to create standalone content for social media or marketing, the LemonSlice Studio provides a suite of tools:

• AI Lip-Sync: Upload an image and a script (or audio file) to generate a high-quality (1080p) video of the character speaking.
• AI Music & Singing: LemonSlice can make your characters sing. You can describe a musical style, and the AI will generate a track that the avatar performs.
• Multi-Speaker Conversations: You can animate multiple characters within a single frame, making them interact with each other.

3. Advanced Customization

• Voice Library & Cloning: Choose from over 100 AI voices across 30+ languages, or clone your own voice with a short audio sample.
• Stylized Characters: It isn’t limited to humans. You can animate 3D avatars, illustrated characters, or even inanimate objects if they have a “face.”
• API for Developers: For teams building custom apps, LemonSlice offers a robust API and SDK that integrates with popular frameworks like LiveKit.

Top Use Cases

• Education: Create interactive tutors. Imagine a cartoon alien teaching a child math or a historical figure “personally” explaining their life story.
• Customer Support: Replace dry FAQ pages with a 24/7 video assistant that can guide users through troubleshooting or intake forms.
• Sales Enablement: Scale personalized product demos. A video agent can greet a lead by name and walk them through features in real-time.
• Corporate Training: Use avatars for roleplay-based training (e.g., sales or medical simulations) where the AI reacts dynamically to the trainee’s responses.

How to Get Started

1. Visit the Website: Go to lemonslice.com.
2. Try the Demos: You can chat with pre-made characters (like a Spanish tutor or a business coach) directly on the homepage for free.
3. Create Your Own:
   • Upload an image: Use a real photo or generate one using AI.
   • Select a Voice: Pick a voice from the library or upload your own.
   • Set the Prompt: Give your agent a “brain” by writing a system prompt (e.g., “You are a helpful travel agent who specializes in European tours”).
4. Deploy: Copy the single line of code to embed the widget on your site or use the Studio to download your generated clips.

Safety and Ethics

LemonSlice takes safety seriously. The platform includes:

• Consent Guardrails: Users must attest that they have permission to use the uploaded images and voices.
• Clear Labeling: All interactive widgets are clearly labeled as AI so users know they aren’t talking to a real human.
• Content Moderation: Integrated filters prevent the generation of harmful or inappropriate content.

Conclusion

LemonSlice is moving beyond the “uncanny valley” by prioritizing charisma and speed. For AI power users and businesses, it offers a unique opportunity to humanize digital interactions. Whether you’re looking to boost website conversions or create the next viral AI-generated music video, LemonSlice provides the tools to bring any character to life in seconds.
