Paxton AI is a legal AI assistant for research, drafting and case file analysis, with a rare published price of $2,999 per user a year or $499 a month. It suits solo lawyers and small firms that want AI research without a large database contract, and the 7 day trial makes it easy to test. Firms that need Westlaw or Lexis depth, or published accuracy figures, should look at the big research vendors first.
What Paxton AI is
Paxton AI is an AI assistant built for lawyers. It drafts legal documents, analyzes case files and researches the law Paxton pricing ↗ Paxton AI ↗. Paxton says more than 30,000 attorneys use it and that it has processed more than 150 million legal documents Paxton AI ↗.
The product is split into modules. Quick Start Drafting writes motions, briefs, discovery responses and deposition outlines, which Paxton says are grounded in the record and relevant law Paxton AI ↗. Document Analysis finds facts, gaps and contradictions across large case files Paxton AI ↗. Contextual Research checks authority against a matter's facts, procedural posture and jurisdiction Paxton AI ↗.
Its pricing page describes a knowledge base of US federal regulations, state laws and case law across all 50 states Paxton pricing ↗. The home page adds agency, municipal and local coverage, and cites more than 100,000 sources Paxton AI ↗. It also produces medical chronologies and medical billing summaries, which help personal injury work Paxton pricing ↗ Paxton AI ↗.
What it does well
The price is public. Most legal research AI is quote only, including CoCounsel Legal and Lexis+ AI CoCounsel Legal ↗ Lexis+ AI ↗. Paxton lists $499 per user a month or $2,999 per user a year, so a solo lawyer can budget without a sales call Paxton pricing ↗.
It covers several jobs in one tool. Drafting, research, file analysis and medical summaries sit in one plan, which suits a small litigation practice Paxton pricing ↗ Paxton AI ↗.
It fits into existing tools. Paxton says it connects to a document management system, Microsoft Word, Outlook and Claude, with two way document sync Paxton AI ↗.
Security claims are clear. The pricing page lists SOC 2, ISO 27001 and HIPAA Paxton pricing ↗. That matters because ABA Formal Opinion 512 says lawyers using generative AI must protect client information unless the client gives informed consent ABA ↗.
You can try it first. Paxton offers a 7 day free trial on the Individual plan Paxton pricing ↗. Hands on testing on our side is in progress.
Where it falls short
No accuracy figures are published. Paxton's home page gives no benchmark results and does not mention citation checking Paxton AI ↗. That is a real gap: a Stanford study found even tools tied to legal databases gave wrong answers on a meaningful share of test questions, including more than 17 percent for Lexis+ AI Stanford HAI ↗. Check every citation yourself.
Monthly billing is expensive. At $499 a month, a year of monthly billing costs about twice the $2,999 annual price, and Paxton itself says the annual plan saves 50 percent Paxton pricing ↗.
It is not a full research database. Paxton does not say it includes citator tools like Shepard's, which Lexis+ AI uses to check sources Paxton AI ↗ Lexis+ AI ↗. Firms that rely on Westlaw or Lexis for citing authority may still need those subscriptions.
The data policy is vague. The home page says Paxton prioritizes the privacy of your legal research, but does not state whether your data is used for model training Paxton AI ↗. Ask before you upload client files.
