About Trellis Research
Introduction
Trellis is a legal research and litigation analytics platform focused specifically on U.S. state trial courts, a segment of the court system that generates the overwhelming majority of U.S. litigation but has historically been thinner ground for traditional research databases built around federal and appellate case law. Founded in 2018 and having raised $36 million in funding, Trellis positions itself as the largest research platform for state trial court data, using AI to turn raw docket and filing data into structured insights on judges, verdicts, opposing counsel, and motion outcomes. In May 2026 the company launched a direct connector for Anthropic's Claude, allowing AI assistants to query its litigation dataset directly, followed by Trellis Chat in August 2026, agentic research built for state trial courts.
Legal Research
Trellis indexes state trial court dockets, motions, and filings at a scale most general legal-research tools do not reach, letting litigators search by court, judge, case type, and legal issue to see how similar cases have actually played out in practice rather than relying solely on published appellate opinions.
Predictive Analytics
The platform's core differentiator is analytics on judges (ruling tendencies and case-management style), verdicts (outcomes and award ranges by case type and venue), and opposing counsel (litigation history and track record), which litigators use to inform strategy, venue selection, and settlement posture ahead of a case.
Pricing
Trellis publishes a Lawyer Entry plan at $120 per month, covering search, alerts, motion and issue tracking, judge bios, case updates, state law access, and up to three user accounts. Higher-volume firm and enterprise tiers are not fully published and require contacting Trellis directly.
User Reviews and Ratings
Trellis is listed on Capterra and GetApp with generally positive user feedback centered on its unique state-court coverage and judge/verdict analytics, though a single strong consensus numeric score across review platforms was not consistently available at the time of this review.
Verdict
Trellis is a strong, differentiated pick for litigators whose practice runs primarily through state trial courts and who want judge- and verdict-level analytics that general legal-research databases do not offer. It is a poor fit for transactional practices or firms whose work is concentrated in federal or appellate matters, where its state trial court focus adds little value.
