Trellis is a legal research and litigation intelligence platform built around U.S. state trial court data. The features page also describes federal court coverage.
Legal professionals use it to search cases, court documents, rulings, and motions. The platform adds analytics on judges, law firms, and companies.
Trellis AI adds document tools for drafting arguments, preparing client briefings, suggesting defenses, and building timelines. The company says attorneys developed these tools on its litigation database. They use one-click actions instead of long prompts.
The company also offers a Trial Court Data API. Organizations can use it to feed litigation data into their own software.

Trellis AI tools for arguments, defenses, and timelines
Use Cases
Preparing for a motion hearing
An attorney researches past rulings on a motion type and reviews related issues. The argument-drafting tool then produces a first structure for lawyer review.
Evaluating a judge beforehand
A litigation team reviews a judge’s historical rulings before filing. The data informs preparation but cannot guarantee how the judge will decide.
Assessing corporate litigation exposure
In-house counsel examines a company’s litigation history, patterns, and outcomes. The findings can support internal risk reviews and strategy discussions.
Writing client case assessments
The Client Briefing tool organizes facts, claims, defenses, and possible outcomes into one assessment. The responsible lawyer must still check the result.
Tracking new litigation activity
Teams follow new filings for chosen companies, industries, or practice areas. This reduces reliance on manual docket searches.
