Legal AI company Harvey unveiled a new capability for litigation, disputes and internal investigations at its FORUM event in Chicago on 5 November. The company announced it in a product presentation and on its blog.

In a dispute, Harvey said, lawyers have to assemble thousands of facts into a strategic picture. That picture shows who knew what and when, whether accounts hold up against the evidence and where evidence is still missing. Fact graph is the company’s name for the capability that does this assembly work.

How the fact graph works

As Harvey describes it, the fact graph extracts facts from each document and links each fact to the exact line of text where it was found. It also connects facts to one another and to the people, events and legal issues they concern. The company said it finds these connections even when related facts sit years apart.

When new documents are added to a matter, the system connects their information to the existing record and flags inconsistencies. Canadian site legaltech.ca reported that lawyers review these potential inconsistencies themselves.

Harvey’s AI agents can use the assembled facts to draft first versions of timelines, witness outlines and memos, for example. The system also alerts users when previously prepared work has become outdated, Harvey said.

Facts, sources, review decisions and finished work stay together throughout. A lawyer who joins the matter later can see from the activity log how earlier information was assessed, the company said. The fact graph is part of Harvey Graph, which the company’s agents use as their knowledge source. This data structure combines legal knowledge with matter context.

Accounts of availability differ

The description of how the capability works comes from Harvey. Reports by Blockchain.News and legaltech.ca are also based on the company’s announcement and include no independent testing.

The sources describe availability differently. Harvey’s fact graph blog says Early Access opens soon. The company’s event round-up says it is already open, with users joining through a waiting list. Legaltech.ca describes it as still a preview that Canadian teams can also sign up for.

Harvey is developing the capability with design partners including the British law firm Slaughter and May. About a third of its customers are litigators, Harvey said.

At the same event, Harvey said its agents now work in Outlook through an add-in. For in-house legal teams, the company opened early access to Intake, a service that receives requests from the business. Two-way sync with iManage document management will enter early access soon, the company said.
