"One of the most wonderful things about Clearbrief is that it is hooked into LexisNexis and...will tell you if some of them are hallucinations. It spares you the embarrassment of getting publicly flogged by a judge for submitting a brief with fake cases."

Lisa H., Director of Tech Innovation · June 2026

"We dropped it into Clearbrief's AI, and were able to quickly delineate, hyperlink all these things that let us know - one: can we win this case, can we meet our burden of proof? ...after 4 weeks, we got the big verdict."

Robert S., CEO · May 2026

"The flow is very user-friendly. I love adding charts to my briefs and table builder is proving to be very helpful, but the main value for me is navigating a massive appellate record and using the add fact-cite tool as a time saver."

Tom A., Member · April 2026

"Clearbrief's hyperlinked briefing and timeline tools for one of my trials...were instrumental in helping me win a $1.5M victory for my clients. The robust security gave me confidence to upload confidential client documents."

The State Bar of Nevada's AI Work Group evaluated multiple legal AI tools and ranked Clearbrief #1, noting its 'robust suite of capabilities promise immense time savings.' It automates tedious tasks like building a Table of Authorities, creating case timelines, and checking an opponent's brief for factual weaknesses.
