CASUS is the ideal innovation partner for our legal department. The team thinks far into the future while creating meaningful impact in the here and now.
Tereza Jášková, Managing Director & Senior Legal Counsel AI, LegalTech, Data & Cyber Security, Alpiq AGIdeal for anyone without extensive IT resources: CASUS is a plug-and-play solution that works. It is a real advantage, especially for small and medium-sized teams in law firms and legal departments.
Dr. Beat Brechbühl, Senior Partner at Kellerhals Carrard and President of SVC for SMEs, Kellerhals CarrardNew software often fails because people do not adopt it. CASUS was quickly embraced by our team because it fits into existing workflows rather than replacing them. That is exactly what I expect from a tool.
Marcel Held, Chief Operating Officer, Domenig PartnerFor us as a Swiss law firm, it was non-negotiable: our data stays in Switzerland. CASUS delivers on that without compromise, and with a product that sets the bar.
Dr. Martin E. Looser, Partner, Küng RechtsanwälteYesterday an experiment, today part of how we work, tomorrow indispensable: CASUS.
Avv. Niccolò Salvioni, Owner, Studio Legale e Notarile Niccolò SalvioniWhat convinced me about CASUS is not just the technology, but the responsiveness behind it. Whenever I have a question, I hear back from support on the very same day.

Evaluating CASUS for your firm?
CASUS is a legal AI platform for drafting, reviewing and editing legal documents. It combines a web application with a Microsoft Word Add-in, so legal professionals can work in the tools they already use. CASUS supports the work; legal judgment remains with the responsible professional.
CASUS is for individual legal professionals, law firms and in-house legal teams. It is designed for day-to-day legal work in DACH and can also be used outside the region with a valid VAT/UID number.
CASUS was founded in Zurich in 2020 and is a spin-off from the University of St. Gallen (HSG). We build legal AI for the standards, confidentiality and practical workflows of legal professionals.
CASUS helps legal professionals deliver precise, consistent work at the speed their clients and business expect. It is built to strengthen legal craft, not replace professional responsibility.
Yes. CASUS is growing and regularly looking for motivated talent across Legal, Tech, Product and Business roles. You can find all open positions and details about the application process on our careers page: https://join.com/companies/casusch
With CASUS, you can automatically analyze contracts, identify risks, detect missing or unusual clauses, and summarize documents in a clear and structured way. In addition, the AI-Chat enables direct interaction with your own contracts: you can ask targeted questions, have passages explained, or compare content—always in context and based on your document.
No. CASUS is designed so that non-lawyers can better understand legal documents as well. The AI explains content in a clear and accessible way and highlights relevant points. For lawyers, CASUS acts as an intelligent second pair of eyes that reduces routine work and supports quality control.
No. CASUS is an assistance tool, not a replacement for legal advice. The platform provides analyses, indications, and structuring support, but it does not make legal decisions. Professional judgment and responsibility always remain with the human user. This does not constitute legal advice.
CASUS is not a public AI tool, but a purpose-built, secured legal AI solution for professional use. Unlike generic AI tools, CASUS focuses on legal workflows, context-aware document analysis, and strict data protection and professional secrecy. It is specifically designed for working with confidential legal documents.
No. CASUS is intentionally lightweight. The platform is ready to use immediately, requires no IT rollout, and involves no complex change processes. This allows teams to become productive quickly and use AI pragmatically in their daily work.
CASUS reduces manual review effort, accelerates routine analyses, and improves quality assurance. Lawyers gain more time for strategic tasks, while error sources are minimized and decision-making becomes more transparent.
CASUS enables law firms to adopt legal AI quickly and with minimal risk. Without system disruptions and without jeopardizing client data, review processes can be accelerated, quality ensured, and internal resources used more efficiently—a clear competitive advantage in an increasingly efficiency-driven market.
CASUS helps in-house legal teams increase efficiency without adding complexity or dependency on IT. By enabling fast, secure contract analysis within existing workflows, legal teams can handle higher workloads, respond faster to the business, and reduce repetitive manual work—while maintaining full control over sensitive company data. This allows legal departments to keep pace with organization-wide efficiency expectations without compromising compliance or quality.
