Microsoft shakes up legal tech with contract review agent

Microsoft has made a major move into legal tech territory with the launch of a contract review “Legal Agent” built directly into Word.

The new feature allows lawyers to review, edit and negotiate contracts inside Word using structured workflows, including clause-by-clause analysis against internal playbooks, automated redlining and citation-backed suggestions.

Legal tech move

The move follows Microsoft’s hire of an 18-strong team of product managers and legal engineers from legal AI startup Robin earlier this year - a move that now looks like a clear precursor to this launch, particularly with Kitty Boxall, formerly Robin’s director of legal engineering and now a principal product manager at Microsoft fronting the launch video.

Microsoft said the Legal Agent was “built in close collaboration with legal engineers to reflect how contracts are reviewed and negotiated”, following structured “structured workflows shaped by real legal practice” rather than relying only on general AI outputs.

It can analyse agreements, compare versions, flag risks against a playbook and propose edits, while keeping formatting and tracked changes within Word.

Big Tech moves closer

The feature has clear overlap with tools offered by legal AI companies, particularly those offering contract review tools and Word integrations.

It is also the latest sign of Big Tech edging further into legal work. Anthropic recently launched its own Word integration for its Claude assistant and struck a major partnership with Freshfields to build legal AI tools.

For law firms, Word remains the backbone of legal document work, and improvements built directly into the platform could reduce reliance on multiple third-party tools layered on top.

At the same time, the development will raise questions for some vendors. As Non-Billable noted when Microsoft hired the Robin team earlier this year, those players may now find their differentiation increasingly under pressure.
