Robin AI was an enterprise legal AI platform for contract review, drafting, and analysis, delivered as a Microsoft Word add-in and a web-based contract workspace. Lawyers could ask questions about long contracts, get suggested redlines and clause edits, check defined terms, summarize obligations, and query across document sets. It ran a hybrid model: Anthropic's Claude combined with its own proprietary data and machine-learning techniques, and was an early Anthropic partner from 2022. Important status note: Robin AI effectively wound down as an operating company in late 2025 and early 2026. After failing to close a new funding round, its managed-services arm transferred to another firm in December 2025, and Microsoft acqui-hired part of its engineering team in January 2026 to work on Word for lawyers. Microsoft stated it had no plans to acquire the company itself. The product's continued availability is uncertain; the capabilities below describe Robin AI as it operated through 2025.

Strengths

  • +Deep early Anthropic and Claude integration with a safety-and-reliability emphasis; handled very long contracts
  • +Native Microsoft Word add-in plus an enterprise contract workspace with iManage and NetDocuments connectivity

Limitations

  • −The company effectively wound down in late 2025 and early 2026; product continuity and support are uncertain
