OpusLaw

What OpusLaw is

OpusLaw is a web-based legal AI workspace for research, analysis, drafting, and practice management across jurisdictions. It searches statutes, regulations, and case law and produces jurisdiction-aware drafts with citations. Contract analysis surfaces risk clauses and inconsistencies and suggests redlines. The site says Carta AI answers questions in 25 languages, while its FAQ says it can draft in over 50 languages. The FAQ describes integrations with common practice management and document management platforms, plus custom enterprise integrations. OpusLaw says data is encrypted in transit and at rest, confidential data is not used to train its AI, and matters remain isolated. It also says data residency options are available and cross-border transfers require explicit consent and an appropriate legal basis. A free plan is available. Paid monthly plans are Carta Actus at $9.99 a month, Carta Corpus at $29.99 a month, Carta Magistra at $79.99 a month, and Carta Suprema at $149.99 a month. The FAQ advises treating AI output as a first draft or research aid, with attorney review beneficial for bespoke drafting.
