Appreciated By

Dayton Meadows, who began using Counsel Stack at his practice in Morgantown, said the platform replaced his existing management software and became "an invaluable tool" for research. Rather than replacing human work, he said it empowered his small team, which includes just one other attorney, a paralegal, and an intern. "It makes you exponentially better," he said.

Founder, Criminal Defense Firm
"I can give it an entire case file and say 'What patterns do you notice? Summarize it for me,' and it can do that. The alternative is that I spend half my day doing it, and I might not find anything."

Founder, Estates and Trusts Firm
"I would recommend Counsel Stack to any litigator like myself, but also to any in-house counsel, compliance personnel, or journalist."
