Changelog

Trellis changelog

Every tracked product and technology change at Trellis, dated and sourced. Each entry names the change, its impact and the live source it was graded from.

Product and technology changes only. Funding rounds, valuations, partnerships and awards are excluded, and an acquisition appears only where there is direct product impact. Every entry cites a live retrieved source. Changes to the index's own records are not changelog material; a corrected record carries its own dates.

Integration / interoperability

Trellis released a connector that brings its state trial court data into Microsoft 365 Copilot as part of Microsoft's Copilot for Legal initiative, available through the Microsoft Marketplace. Attorneys can find successful motions, research judges and opposing counsel, and draw on trial court filings while drafting in Word. It needs a free Trellis account and an eligible Microsoft 365 Copilot license.

Buyer relevance. Firms standardized on Microsoft 365 Copilot can reach state trial court records without leaving Word or Copilot, and IT controls access through Microsoft's connector administration.

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 If a record is wrong, out of date, or missing an artifact the index did not locate, send the source and it will be reviewed and the record redated.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.

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.
