Legion is a revolutionary product that has transformed my practice and productivity. I represent small and medium sized businesses and Legion has been a blessing for my clients with smaller matters. The cost savings is tremendous and they have all appreciated my use of generative AI. Legion has come in the clutch for me when time is tight. I really enjoy using it because it is fun and easy to use, and my practice has certainly leveled-up.

Much of AI legal tech remains theoretical. Legion is different: a practical tool California litigators can use today to deliver client value while focusing on strategy and counseling. It responsibly automates time-intensive workflows under your supervision, producing work product matching or exceeding your standards. While "ChatGPT Lawyers" face sanctions, Legion Lawyers build sustainable practices prepared for AI's revolution.

I was an AI Grinch and had been completely unimpressed by the legal tech I tried. Legion changed that. When negotiations stalled in a case and the adjuster wasn't responding, I drafted a complaint with Legion and sent it to the adjuster. I received an immediate response. Legion not only saved me time, but it also got my client the settlement they deserved faster.
Kyle Smith

I work with small businesses and clients who don't have a ton of resources to spend on legal fees. The Legion platform allows my clients to have access to my full suite of services much more efficiently and without sacrificing quality. Recently, I was able to leverage a complaint generated by Legion to successfully come to an agreement with opposing party within one week.

Legion has been and remains a leader in ethical AI use for plaintiffs' firms. Their tools are able to take entire days off the early drafting process and allow our lawyers to focus on refining documents rather than reinventing the wheel each time.
David Gammill

The tool that Legion has built to format discovery shaves hours off the process. Objections can be added, removed, and modified with a single click, and the AI will automatically update the formatting. Instead of a black box churning out work product, Legion provides easy ways to review and make changes during the process. I use it in almost every round of discovery I conduct in my practice.

California litigation moves fast, and our clients expect us to move with it. Legion lets us respond to new matters, build discovery, and get drafts in front of clients much more quickly than we could before. That speed is not just an internal efficiency; it changes what we can offer clients and how we position our firm. We are a small team that punches above our weight, and tools like Legion are part of how we do that.

Your work product is yours alone. We expressly prohibit the use of your prompts, outputs, or uploads to train or fine-tune our models. Your client‘s facts will never teach our AI.
