Illustrative example. Every item comes from read-only lookups in Mary.

Ex. 1Before a word is drafted

Every draft starts from the reviewed record.

Without Mary, AI tools draft from whatever facts you feed them or they summarise. With Mary connected, each tool starts from your team’s reviewed factual record, with negative space interrogated and analysed.

FactualWhat your team verified, with the source page and who signed it off.
CounterfactualThe competing account stays in view, with the reviewer’s note.
GapsWhat should exist and doesn’t, so the draft never assumes it.
Track RecordCorrections, rejections and reviews from the audit trail.
Grounded draftCreated inside Mary, cited to the record and reviewed like everything else.

Connect Claude to Mary in three steps.

  1. 1Add Mary as a connectorIn Claude’s connector settings, search for Mary, then select Connect.
  2. 2Sign in with your Mary accountClaude sees what you can see in Mary, and nothing more.

Your firm’s Claude admin may need to allow the connector first. Guides for Copilot and ChatGPT follow the same three steps.

Ex. 6Questions

Questions about connecting AI.

Will a connected AI change the facts in Mary?

No, it can’t edit entries or mark anything verified. That stays with your team in Mary. Your connected AI can start new work, such as a chronology or a draft, which is saved to the matter.

What does the AI provider see?

A connected AI reads only the matters the signed-in lawyer can see, in your firm’s data region. It can read facts, sources, flags and review history, and ask Mary to start new work.

Can we connect our own applications?

Yes. Point any MCP client at Mary for witness prep, investigations or internal tools, with the same permissions as the signed-in lawyer.
