Having Already Launched A Claude Connector, Trellis Extends AI Access to Its Court Data

Trellis, a legal research company that provides state trial court data and insights, has expanded agentic AI access to its data with a new plugin for OpenAI’s ChatGPT and a native assistant called Trellis Chat, both of which are in addition to the Trellis.

These integrations are intended to enable litigators to query that data from inside the AI tools they already use. Attorneys can pose research questions in Claude or ChatGPT, and the connectors pull in relevant filings, rulings, verdicts, and judicial data, rather than leaving the.

What Happened

Trellis Chat offers the same experience from inside the Trellis platform. Trellis says these connectors enable attorneys to get responses that go beyond simple chat.

• Trellis says its coverage spans more than 3,500 courts across 2,500 counties in 45 states.

• The Trellis connectors for Claude and ChatGPT are the first in a series of planned integrations that will extend agentic access to its trial court data across the tools attorneys already use, the company.

• Using the Trellis MCP, Cowork produced a memorandum with charts, factual analogues, comparable verdicts as damages benchmarks, and citations to underlying dockets, Trellis says.

Key Details

Trellis describes an Am Law 100 partner asking Claude Cowork to find factually similar California premises-liability cases involving large retailers and alleged notice of a spill hazard.

• Rather than return a single answer, the connectors let a user describe a research goal and have the system plan a strategy, search the records, cross-reference results against actual verdicts and motions, and check.
