Why it matters

Most legal AI only speaks English.

ChatGPT offers basic translation. Other legal AI tools are English-only by design. If your practice touches any non-English-speaking jurisdiction, those tools leave you exposed. Carta AI was built from the ground up for global legal practice.

European Languages

Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, and more — with full Civil Law and EU regulatory knowledge.

Asian Languages

Chinese, Japanese, Korean, Hindi, Thai, Vietnamese, Indonesian, Malay — covering the world's fastest-growing legal markets.

Middle East & Africa

Arabic, Hebrew, Turkish, Persian, Swahili, Afrikaans — including Islamic law, Jewish law, and regional regulatory frameworks.

Mixed Legal Systems

South Africa, Scotland, Quebec, Louisiana, and other jurisdictions with hybrid legal systems require nuanced AI. Carta AI handles them.

Our firm handles cross-border M&A across Southeast Asia and Europe. Carta AI is the only tool that actually understands the legal systems in all our markets — not just translates the words.
