Capabilities

Capabilities built for your practice.

Legal-specific training

Trained on legal databases, case law, and regulations — not general internet content. Understands precedent hierarchy and professional standards.

Cite-verified output

Every research output is built on verified legal sources. Carta AI does not hallucinate case citations or invent statutes.

Attorney-client privilege protection

Enterprise-grade encryption and secure cloud infrastructure. Your client data is never used for model training and remains fully confidential.

50+ jurisdictions

Deep legal understanding across 50+ jurisdictions and legal systems, with multilingual document support.

Precedent understanding

Comprehends precedent relationships, jurisdictional differences, and the relative weight of authority — critical for real legal work.

Professional standards compliance

Built around the ethical and professional obligations of legal practice, unlike general-purpose AI tools.

I tried using ChatGPT for legal research and nearly made a costly mistake. The precedent it cited was overturned years ago. Carta AI's verified research saved my case and my reputation.
