AI Legal Index
Record

Changelog

What changed at AI vendors in legal, dated and sourced, and what changed on this index. Only product and capability changes qualify. Funding rounds, valuations, partnerships and awards are excluded, and an acquisition appears only where there is direct product impact. Every vendor entry cites a live retrieved source. Corrections and regrades publish in the same stream as everything else.

Integration / interoperability

RelativityOne now integrates with Microsoft Copilot over the Model Context Protocol. Users can run administrative reporting against their RelativityOne environment using natural language prompts issued from Copilot.

Buyer relevance. Administrative reporting moves into the Microsoft 365 surface legal teams already sit in, which removes a context switch for work that was never worth opening a second platform for. The value here depends on an existing Copilot deployment.

Integration / interoperability

RelativityOne can now collect Claude Enterprise data directly from the source using Anthropic's Compliance API. The connector maps, preserves and processes conversation prompts, responses, chats and uploaded files into a reviewable form, including normalisation into Relativity Short Message Format.

Buyer relevance. Legal and compliance teams get a defensible collection path for conversational AI evidence, with context and metadata intact rather than reconstructed from exports. For any organisation that has rolled out Claude Enterprise, this is the difference between an eDiscovery source that is reviewable and one that is not.

Correct a record, or ask how something was graded

Every grade and every signal on this index is drawn from public sources and dated. If a record is wrong, out of date, or missing an artifact the index did not locate, send the source and it will be reviewed and the record redated. Vendors are welcome to submit documentation. Nothing on this index is for sale, including a listing, a placement, or a grade.

AI Legal Index

The AI Legal Index is an independent index that tracks changes to AI vendors in legal. It holds 61 vendors across 9 categories, each graded on the same 15 capability axes and recorded against 12 legal signals, from public sources. No vendor pays for inclusion, placement, or rating.

September 5, 2026
The AI Legal Index is an editorial reference. It is not a regulatory body, not a law firm, and nothing published here is legal advice or a recommendation to retain or avoid a vendor. Records are verified against published sources, bar guidance and public court records. Where a record reads not addressed, the material was not located in public sources on the date shown. See the Methodology page for evaluation standards and limitations.
