Towards LLM-Augmented Legal Practice

How We Help

Counsel Stack replaced my existing management software and became an invaluable tool for research. Rather than replacing human work, it empowered my small team, which includes just one other attorney, a paralegal, and an intern. It makes you exponentially better.

Criminal Defense Firm

When I first started practicing, there were lots of goose chases where I'd spend hours researching something that turned out to be useless. I can give Counsel Stack 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.

Wills, Trusts and Estates

What I cooked up with Counsel Stack today was 🔥. I'm a huge fan of the "Can you rephrase and refine this <insert my current understanding of a jurisdiction and doctrine>". I do like how you have the GUI set up. It really makes it easy to do research and drafting in one place.
