AI Legal Index is an independent editorial reference that tracks vendors offering artificial intelligence products and services for the legal sector. Its directory covers 303 vendors across nine categories, with each vendor assessed using the same 15 capability axes and recorded against 12 legal signals. These signals include areas such as privilege posture, citation accuracy, corpus provenance, and support for court disclosure.

The index offers a vendor directory, head-to-head comparisons, information about its evaluation signals, a brief, a changelog, and a methodology guide. Its records and grades are based on dated public sources, bar guidance, and public court records. Vendors may submit documentation, and readers can report errors or request review of missing or outdated information. The index states that inclusion, placement, and ratings are not for sale.

AI Legal Index is not a regulatory body or law firm, and its content is not legal advice or a recommendation to retain or avoid any vendor.
