Our verdict on LEO
LEO is PrudAI’s legal AI assistant for lawyers and in-house counsel, designed for Dutch legal practice. It brings legal research, matter-file analysis, and legal writing into matter-focused workflows. Answers link statements to source passages, while a citation auditor checks citations against those sources. Small teams that need cited research alongside drafting and document review are its clearest fit; teams seeking a general-purpose assistant or work outside its intended legal context may prefer another tool.
Its workflow spans research across legal authorities and domain-specific sources, analysis of uploaded documents, and tools for contract screening, chronology building, and structured document comparison. A Microsoft Word add-in supports drafting and rewriting, while SharePoint integration connects the product with document libraries; ORDO is also listed as an integration. LEO is cloud-based and available on the web. That combination suits teams already working in Word and SharePoint, particularly when research and matter documents need to stay connected. The product is more focused on legal practice than broad office automation.
According to the vendor’s pricing page, LEO Professional costs €179 per month with monthly billing or €149 per month with annual billing. Both listed plans include dossier and case-law analysis, structured analyses, a legal and tax source library, and SharePoint integration. The Professional plan has a 14-day trial, and no card is required for the trial. GDPR is listed among its compliance details. The vendor describes ISO 27001 certification as expected in Q4 2026, rather than as a current certification. The annual rate lowers the monthly price but requires a longer billing commitment, so teams should compare that commitment with their expected use. Pick LEO for cited legal research and connected matter drafting; consider alternatives if the intended Dutch-practice focus or annual-rate commitment does not fit.
