description: 'Casetext is a legal technology company founded in 2013 by Jake Heller, Joanna Huey, and Laurence Pfeffer and
  headquartered in San Francisco, California. The company built one of the earliest neural-search engines for U.S. case law
  (Parallel Search) and a broader research platform covering federal and state cases, statutes, regulations, and secondary
  sources, with citator signals delivered through its SmartCite feature. Casetext is best known for CoCounsel, a generative-AI
  legal assistant released in March 2023 and originally built on top of OpenAI''s GPT-4, that automates document review, deposition
  preparation, contract analysis, legal research memos, and database queries for law firms and in-house legal teams. Companion
  products include AllSearch, a private document search tool that lets firms run Parallel Search across their own document
  collections, and Compose, an automated brief-drafting product. Thomson Reuters acquired Casetext in June 2023 for $650 million
  in an all-cash deal that closed on August 17, 2023, and CoCounsel has since been integrated across Thomson Reuters'' Westlaw,
  Practical Law, and HighQ product lines as the company''s flagship legal-AI assistant. Casetext is now a RETIRED BRAND rather
  than an active provider: casetext.com began redirecting to a Thomson Reuters CoCounsel page on February 1, 2025, CoCounsel
  1.0 access on the Casetext platform ended March 31, 2025, and the standalone platform was shut down on April 1, 2025. As
  of August 2026 every path on the domain returns HTTP 410 Gone behind a hand-written retirement notice pointing users to
  Westlaw, and the developer-facing subdomains do not resolve. Casetext never published a public developer API, SDK, or machine-readable
  specification of any kind; the casetext GitHub organization holds 79 fully archived repositories — research forks (transformers,
  ELECTRA, pgvector, FiD) and early JavaScript infrastructure utilities — and the 15 npm packages it published are general-purpose
  libraries rather than API clients, the newest released in June 2018.'

x-retired-links:
  note: These pointers were removed from common[] on 2026-08-10 because every one of them returns HTTP 410 Gone. They are
    retained here as history, NOT as claims. Several were scored checks — Pricing (4 pts), Login/SignUp (5 pts) and Blog (1
    pt) are bare `common[].type includes "X"` rules, so the profile was drawing 10 points of credit for pages the provider
    had explicitly marked Gone. A 410 is the provider stating the resource is permanently removed; it is the strongest possible
    evidence AGAINST presence.

    note: Not a dead link — a FABRICATION. The file was an API Evangelist conceptual schema that said so in its own text ("this
      schema is a conceptual model"), yet was wired as if Casetext published a GraphQL API. Quarantined to _fabricated/graphql/
      on 2026-08-10. https://casetext.com/graphql returns 410.
