OpusLaw is a web-based legal AI workspace for research, analysis, drafting, and practice management across jurisdictions.
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. Its contract analysis identifies risk clauses and inconsistencies and suggests redlines. The site says Carta AI answers in 25 languages, while its FAQ says it can draft in over 50 languages. The FAQ also describes integrations with common practice management and document management platforms, with custom enterprise integrations for specific workflows. 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 transfer requires explicit consent and an appropriate legal basis. The service has a free plan. Paid monthly plans listed 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. OpusLaw advises treating AI output as a first draft or research aid, with attorney review beneficial for bespoke drafting.
