Trellis Research was founded in 2018 in California to build what it describes as the largest legal research and analytics platform focused specifically on U.S. state trial courts, an area historically underserved compared to federal and appellate coverage from incumbents like Westlaw and Lexis. The company has raised a total of $36 million in funding, with its most recent disclosed round in August 2023, and in May 2026 launched a direct connector for Anthropic's Claude, giving AI assistants structured access to its litigation dataset.

Review of Trellis, the AI-powered state trial court research and litigation analytics platform: features, pricing, judge and verdict analytics, and honest pros and cons.

Trellis Research Review 2026: State Court Litigation Analytics AI

Trellis Research, Inc.

Narrow Focus: Its core value is concentrated in state trial court litigation, so it adds little for transactional, appellate, or federal-court-focused practices.

Custom Pricing Above Entry Tier: Only the base Lawyer Entry plan is publicly priced; firm and enterprise tiers require a custom quote.

Unmatched State Trial Court Coverage: Indexes state court dockets and filings at a scale most general legal-research tools do not reach, covering where most U.S. litigation actually happens.

Judge and Verdict Analytics: Provides ruling-tendency and verdict-outcome data that directly informs litigation strategy, venue choice, and settlement posture.

Transparent Entry-Level Pricing: Publishes a clear $120/month Lawyer Entry plan, unlike many legal AI tools that require a sales call for any pricing information.

AI Assistant Connectivity: A May 2026 Claude connector lets AI assistants query the litigation dataset directly, extending its usefulness beyond the native interface.

<h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Introduction</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Legal Research</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Predictive Analytics</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Pricing</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">User Reviews and Ratings</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Verdict</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">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.</span></p>
