Frequently asked questions

What is the CASUS Word Add-in?
The CASUS Word Add-in brings legal AI into Microsoft Word. It supports legal professionals with drafting, reviewing and editing documents without switching away from the document.
How do I install the CASUS Word Add-in?
The Add-in is officially listed in the Microsoft Store. Install it, sign in and start working. Standard setup takes about five minutes; because it is an officially listed Add-in, IT and compliance approval is usually straightforward. Internal policies can still require additional approval.
Does the CASUS Word Add-in work in Word Online and desktop Word?
Yes. You can use the CASUS Word Add-in in Word Online and in the Word desktop application, provided your Microsoft environment permits Add-ins.
Can I work on documents from SharePoint?
Yes. Open the SharePoint document in Word Online or desktop Word and use the CASUS Word Add-in in that document. A direct SharePoint connection to the CASUS web application is not described here because it is not yet live.
What can CASUS do inside a Word document?
CASUS can answer questions about the open document, draft and rewrite clauses, identify language and consistency issues, highlight risks and compare a document with your playbook or preferred standard. Suggested edits can be applied directly in Word.
Is CASUS secure enough for confidential legal work?
CASUS keeps data in Switzerland and the EU, does not use customer data to train models and is designed for professional and attorney-client confidentiality requirements. The applicable security documentation contains the detailed processing information.
Does CASUS replace legal review?
No. CASUS accelerates drafting, analysis and review, but its output can be incomplete or incorrect. Legal professionals remain responsible for checking the result and making the final judgment.
