Why Carta AI
Built differently, by design.
All Practice Areas
From corporate transactions to family law, criminal defence to IP — Carta AI understands the full spectrum of legal practice without forcing you into a narrow specialty track.
Multilingual Support
Work fluently across 50+ languages. Carta AI understands jurisdiction-specific terminology, not just translated words, so cross-border matters stay precise.
Solo & Firm Pricing
Plans starting at $49/month make enterprise-grade AI accessible to solo practitioners and boutique firms, not just AmLaw 100 clients.
Purpose-Built Legal AI
Carta AI is trained on legal corpora from multiple systems and jurisdictions. Every response reflects how lawyers actually think, not how a general-purpose chatbot approximates it.
Zero Data Retention
Your client communications and documents are never used to train models. Attorney-client privilege is a first principle, not an afterthought.
All Tools Included
Contract analysis, drafting, research, translation, and 10+ additional tools are bundled into every plan — no add-on fees, no piecemeal licensing.
