AI legal platforms
Which law firms and legal teams run which AI — research and drafting assistants, e-discovery review, contract analysis and case management — and since when. Every number below is a count of records we hold and can show a source for — not an estimate of the market.
The firms lists, the court filings and the year-by-year history are Professional features. Open any platform to see what is there.

“Firms we can evidence” counts organisations seen running an address on the platform's own domain in archived captures, and organisations the vendor names in its own customer stories, each checked against the vendor's page. Neither shows which features are switched on, and none of this is a market share.
