Customize your AI language tutor
Upload a photo and watch LemonSlice AI bring it to life with natural expressions, realistic gestures, and lip-sync.

Create a conversational AI agent for language learning in three steps
Step 1: Customize your agent
Select a photo to define the appearance of your conversational AI agent. You can upload a photo or generate one directly with LemonSlice. The photo can be photorealistic, cartoons, or even animals and inanimate objects. If it has a face, LemonSlice can bring it to life.
Step 2: Set up your knowledge base
Upload your lesson materials, grammar guides, vocabulary lists, and approved content. The LemonSlice AI uses this knowledge base to answer questions accurately. You control exactly what information goes in, so responses align with your teaching methods and curriculum.
Step 3: Add the widget to your website
Add the LemonSlice widget to your website with a simple embed code. No technical skills are required. Once live, the conversational AI agent engages visitors to practice their language skills. It works with any website, including Webflow, WordPress, Shopify, and Square.

Navigating the challenges of conversational AI in language learning
It's understandable that language learning companies hesitate to adopt conversational AI on a large scale. They worry about data privacy and security, and fear losing the authentic human touch their audience expects. But these are problems with clear solutions.
Challenge: Data privacy and security
Customers trust language learning businesses with their personal information. Some businesses worry that the use of conversational AI exposes this data to a higher risk of fraud or leaks. This is a legitimate concern, as sensitive user data must remain protected.
Solution: Data security and privacy
LemonSlice builds robust safeguards and secure data handling practices into the platform at every stage of the conversation. Businesses can be confident that all user interactions and personal data, especially in contexts like language learning, remain protected. LemonSlice does not use customer data to train its AI, a practice that gives businesses the confidence to deploy their Conversational AI agent.
Challenge: Personal service
Many language learning companies built their reputation on high-quality personal service. They naturally worry that the introduction of conversational AI could diminish the human touch their customers value. After all, some situations or complex questions make people want to speak with a human expert. The challenge is to find a balance between technological efficiency and the personal connection customers expect.
Solution: Staff and AI working together
Sometimes users want to speak with a person, but often they just want an immediate answer. In language learning, AI and people can collaborate to create an experience that satisfies both needs. The LemonSlice AI handles routine inquiries, freeing human staff to focus on more complex, high-value interactions. We designed the LemonSlice AI to work alongside your team, not to replace it.

What is LemonSlice's conversational AI for language learning?
LemonSlice's language learning conversational AI agents are interactive AI agents that engage with users through real-time video. They use a single uploaded image of any character (photorealistic, cartoon, or an object with a face) or a simple prompt to create a live conversational AI agent that you can embed directly on your website.
What kinds of language learning experiences can LemonSlice's conversational AI agents create?
LemonSlice's language learning conversational AI agents are designed for interactive visual engagement, including:
- Acting as live virtual tutors or practice partners on your website
- Conversational touchpoints that users can talk to in real time
- Expressive, responsive characters that enhance user interaction
Because the technology generates video in real time, it is more immersive than static content or text-only chatbots.
What is the LemonSlice API, and how can developers use it?
The LemonSlice API lets developers programmatically create, launch, and manage real-time conversational AI agents inside their own applications or workflows. It gives you more control than a simple embed and enables deeper integration with your systems.
With the LemonSlice API, you can:
- Create and manage live conversational AI agent sessions using REST endpoints
- Embed agents into custom frontend experiences using a JavaScript SDK
- Control when agents start, stop, and how users interact with them
- Receive real-time events such as agent readiness, visual updates, and errors
This makes it possible to build fully customized interactive video experiences that feel native to your product. View the full API documentation for implementation details and examples.
Do I need technical skills to integrate LemonSlice?
No, basic integration is simple. You can add a conversational AI agent widget to your website by pasting an embed code snippet into platforms like Webflow, Shopify, Square, WordPress, Wix, or any website that supports custom HTML. For deeper customization, backend workflows, or advanced control, including API usage, we recommend you work with a developer.
Can I choose the LLMs for my language learning conversational AI agents?
Yes. All pricing plans include access to premium LLMs to power your conversational AI agents. These include models from multiple providers such as OpenAI (for example, GPT-5, GPT-4.1, GPT-4o), Anthropic (Claude Sonnet 4.5, Claude 3.7 Sonnet, Claude Haiku 4.5), and Google (for example, Gemini 2.5 Flash, Gemini 2.0 Flash Lite), as well as support for custom LLMs.
