Henchman

Henchman is a legal knowledge and contract-drafting AI platform that surfaces a firm's own past clauses and definitions from its document management system directly inside Microsoft Word, Outlook, and Copilot. It connects to legal DMS platforms (iManage, NetDocuments, SharePoint, OneDrive, Google Drive, OpenText eDocs), extracts and ranks clauses and definitions, and adds a secure multi-LLM AI clause assistant on top. Henchman was acquired by LexisNexis in 2024 and is being integrated into Lexis+ AI and Lexis Create+. Henchman is delivered primarily as add-ins and DMS connectors; it does not publish a public developer API.

Henchman publishes 3 APIs on the APIs.io network: Clause and Definition Search, Knowledge Base, and Integrations. Tagged areas include Legal, Legal Tech, Contract Drafting, Clause Search, and Knowledge-Management.

Henchman’s developer surface includes documentation and 7 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/henchman: open an issue to ask a question, or submit a pull request to add artifacts.
