Trellis AI is the most advanced legal AI platform developed and trained by a team of expert AI attorneys. Leveraging multiple large language models, including OpenAI and Anthropic as well as case data and documents unique to Trellis, Trellis AI delivers a highly reliable output that you can trust.

Trellis AI was designed for attorneys and legal professionals of all practice areas and firms of all sizes.

Our attorneys have rigorously tested multiple models and thousands of documents to deliver precise and reliable results. However, output should always be reviewed.

Unlike other AI providers that require a steep learning curve, Trellis AI is designed with ease-of-use and speed in mind, meaning you won’t have to waste time learning how to master precise prompt engineering. We’ve simplified the user experience, without sacrificing accuracy or quality, so it’s as easy as clicking a button.

Trellis AI was built for attorneys, by attorneys, with unique litigation data and insights. This means the product has been reviewed and vetted by legal experts across thousands of legal documents, making the responses more likely to be accurate and reliable. We believe you get what you pay for, and free AI tools are often not as complete, precise or secure.

Trellis AI saves you time by streamlining time-consuming tasks, like document reviews, summaries, timelines, and citation checking, so you can focus on more important priorities.
