Paxton's strength is keeping research, case files and drafts in one matter record, so motions and memos cite both the law and the record. Medical chronologies make it especially practical for personal-injury firms, and pricing is published with a free trial.
Treat the accuracy claims as the vendor's own: its self-run benchmark still showed about 5% hallucinations, so citations need checking. At $2,999 a year per seat it suits US small and mid-sized litigation firms; coverage is US-only.
What we found
Paxton is a legal AI assistant from Paxton AI, Inc., founded by Tanguy Chau and Michael Ulin and headquartered in Bend, Oregon. It was first unveiled in July 2023, raised a $6 million seed round that year and a $22 million Series A led by Unusual Ventures in January 2025, for $28 million in total. It has since repositioned around litigation: each matter keeps its own record of case files, research and drafts, so that research memos, motions, discovery responses and deposition outlines are grounded in both the law and the matter's documents. Medical chronologies and medical billing summaries, added in 2025, aim at personal-injury firms, and an October 2026 update added reusable firm skills and optional web search shown alongside primary law.
The accuracy marketing needs reading closely, because earlier versions of this page called it a no-hallucination guarantee. No such guarantee exists. Paxton's 2023 seed announcement said the system was designed so that it will not hallucinate citations. In July 2024 the company ran 1,600 tasks sampled from a Stanford legal hallucination dataset through its case-law tool and reported 83.3% correct answers, 11.4% abstentions and 5.3% hallucinations, which it presents as 93.82% accuracy and a 94.7% non-hallucination rate. Those are useful numbers, but they come from Paxton's own test, and roughly one answer in twenty still contained a hallucination.
Pricing is published: an individual seat costs $499 a month or $2,999 a year, about half the monthly rate, after a seven-day free trial. Enterprise pricing is volume-based, adding firm-wide access, onboarding, administration and shared document sets. Paxton says it holds SOC 2 and ISO 27001 certification and HIPAA compliance, and it connects to document management systems, Word, Outlook and Claude.
Coverage is US federal and state law plus agency and local sources, so it is a tool for American litigators, particularly small and mid-sized firms that cannot justify Harvey. Lawyers elsewhere in the region will find little of their own law in it.
