Trusted by top trial lawyers across California
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.
Jason Horst
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.

How a San Francisco litigation firm restructured around Legion.
We owe you a product built by someone who still does the work.
I’m Arthur Rothrock, and I still litigate every week. Real cases – mine and our customers’ – drive what we build. The bar I hold Legion to for my own practice is the bar it has to clear for yours.
That’s why Legion isn’t generic legal AI dressed up for California. The work itself shapes the product: pleading paper, non-compound RFAs, counsel declarations, TOC and TOA on briefs over ten pages – every detail California courts demand, built in.
We move at the pace the work demands. Fourteen production workflows shipped since March 2025, a new release roughly every four weeks, and we re-route to whichever frontier model is strongest the day it ships. You’re never running on last year’s tech.
The promise that holds it all together: any time I have to leave Legion for another AI tool, that’s a Legion bug. We build so you never have to.

AES-256 at rest. TLS 1.2+ in transit. U.S.-only infrastructure.
Every byte is encrypted with AES-256 when stored. Every connection uses TLS 1.2 or higher. Customer Data is stored and processed exclusively in the United States – no offshore vendors touching your client’s file.
If a confirmed breach ever affects your data, we notify you within twenty-four hours of discovery. What happened, what was affected, what we did about it.
