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.

Frequently asked questions.
Evaluating CASUS for your firm?
CASUS is an AI workspace for legal work in Microsoft Word and your browser. You can review contracts, draft and edit text, compare documents and ask questions about your files. CASUS supports individual legal professionals, law firms and in-house legal teams in their daily work.
CASUS is built for legal work. You work directly in Word with tools for contract review, proofreading, your own standards and document collections. Particularly important when working with confidential information: your documents are stored in Switzerland and are not used to train AI models.
Your documents are stored in Switzerland. For AI processing, the required content is sent to the services we use in Switzerland or the European Economic Area. CASUS and its model providers do not use it to train AI models. You can find the data flows and contractual documents on our security page.
Yes. In Switzerland, CASUS undertakes a duty of confidentiality as an auxiliary under Article 321 of the Swiss Criminal Code. In Germany, CASUS undertakes a duty of confidentiality as a participating service provider under section 203 of the German Criminal Code and section 43e BRAO. In Austria, CASUS undertakes a written duty of confidentiality under section 9 RAO. CASUS provides a corresponding written declaration.
You can try CASUS free for 14 days and get started directly in your browser. If you like, we can show you a use case from your daily work in a short demo. We can also help you set up the Word Add-in.
You can find the current prices per user and the monthly and annual billing options on our pricing page. If you want to introduce CASUS to several people, we can discuss the right offer for your team.
CASUS helps you check results through sources and references, as well as traceable suggested changes that you can accept or reject. Answers can still be wrong or incomplete. The same question can also produce different answers. Check important statements and suggestions before using them. Your professional judgment remains essential.
You can use CASUS directly in your browser. To work directly in Microsoft Word, you also set up the CASUS Add-in. Depending on your Microsoft 365 settings, this may require approval from your administrator. We help you and your IT team get started.
Yes. With Benchmark, you can compare contracts against your own templates and review standards. In Dossiers, you bring multiple files together and ask questions about a document collection. This keeps the work focused on your matter and your standards.
Message us directly in the chat in CASUS. Our team helps with questions about using CASUS, getting started in Word or a result that does not seem right. Whenever needed, we can look at your use case together in a short call.
