What is Casetext?

Casetext is an AI-driven legal research platform that packages routine research, drafting and review tasks into a single assistant aimed at litigators, in-house counsel and solo to Am Law firms.

Its flagship CoCounsel (launched on GPT-4) performs brief drafting, issue-spotting, contract review and deposition prep, while SmartCite checks citation treatment and flags negative history, and CARA and full-text case-law search let you surface authorities by document or fact pattern.

The system supports document upload for automated analysis and generates research memos and redlines you can edit; integrations and export options are available for common workflows. Pricing is freemium: there's a limited free tier and paid subscriptions or enterprise plans for heavier users.

In real use by 2026 Casetext saves hours on discovery and first drafts but isn't a substitute for legal judgment - the AI can mischaracterize holdings, citation tools aren't infallible, some jurisdictional coverage is patchy, and the most useful features often require the paid plan. Clients handling privileged information should confirm data-retention and confidentiality terms.
