Basics

What is AI Legal Chat?

AI Legal Chat is LexAI's conversational interface for Czech legal research. Powered by our own AI model running on dedicated EU servers, it lets you ask questions about Czech laws, regulations, and court decisions in natural language. Every answer includes citations to official sources so you can verify the information.

Accuracy

How accurate are the answers?

LexAI uses RAG (Retrieval-Augmented Generation) to ground every response in official Czech legal sources. The AI retrieves relevant statutes, court decisions, and legal commentaries before generating answers, and provides direct citations so you can verify everything. However, AI is a research tool - we always recommend consulting a qualified lawyer for specific legal advice.

Languages

What languages does it support?

Our AI model supports 100+ languages natively. You can ask questions in Czech, English, German, or any other language and receive answers in your preferred language. The model is specifically fine-tuned for Czech legal terminology, so it understands the nuances of Czech law regardless of which language you use.

Privacy

Are my conversations private?

Yes. Unlike ChatGPT or Claude, your data never leaves our infrastructure. We run our own AI model on dedicated Hetzner GPU servers in Germany - no third-party API calls, no data sent to OpenAI or Anthropic. Conversation history is stored with zero-knowledge encryption, and we never use your data to train AI models.

Sources

What legal sources does it use?

LexAI searches through a comprehensive database of Czech legal sources including the Civil Code, Criminal Code, Labor Code, court decisions from the Constitutional Court and Supreme Court, official legal commentaries, and regulatory guidelines. Sources are regularly updated to reflect current legislation.
