Lexi - LexAI Mascot

What is AI Legal Chat?

AI Legal Chat is LexAI's conversational interface for Czech legal research. Powered by Claude API (Anthropic) with proprietary RAG integration, 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.

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.

What languages does it support?

Claude 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 understands the nuances of Czech law regardless of which language you use, enhanced by our proprietary Czech legal RAG system.

Are my conversations private?

Yes. Your queries are processed via Claude API (Anthropic) under strict commercial data policies - API data is never used for training and logs are deleted within 7 days. Your conversation history is stored with zero-knowledge encryption in Frankfurt, Germany. Documents never pass through the AI layer. Default PII anonymization protects sensitive data before it reaches the API.

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.
