Dossiers and more speed
With Dossiers, you ask across every document in a matter at once instead of one file at a time. And CASUS has become noticeably faster in the browser and in Word.
CASUS Team,
Dossiers
A Dossier brings together the documents of a matter, a project or a topic. You upload the files, ask your question, and CASUS answers across the whole collection.
Every answer names its sources with the file and the passage, so you can check each statement before you use it.
Typical uses are reviewing many contracts at once, a due diligence in which you pick out clauses such as change of control, or a collection of precedents in which you quickly find the strongest wording. More on the Dossiers page.
Ten times more room
A Dossier now holds ten times as much as before: up to 1,000 files of up to 100 MB each, including Word, PDF, Excel, PowerPoint and Outlook emails.
CASUS uses the whole content for your questions, for example in a litigation file or extensive tender documents.
Noticeably faster
You apply suggestions from reviews and the chat with practically no waiting time, and chat and research answer much faster too.
CASUS also works more precisely in your document. The formatting stays intact, and a change lands only where it belongs. In long contracts with their own numbering and cross-references, you no longer repair the layout by hand.
A new navigation
CASUS in the browser has a new structure, built on feedback from our users. The sidebar takes you straight to your chats, Dossiers and reviews.
Drafts you edit directly
Longer drafts appear in their own text boxes that you edit in place. You export documents as a Word file and open emails in your mail program.
Research beyond Switzerland
We have substantially expanded the legal sources for Germany and Austria, and France and Spain are new. Every answer links its sources so you can check them. More on Legal Research.
Scans and in-depth review
CASUS now also reads scanned PDFs. With very weak scans, text can be lost, so check important passages in the original.
Risk Review and Proofread offer an “In-depth” option. The review takes a little longer and goes into more detail.
Availability
The new features are available in CASUS now. France and Spain are being switched on step by step and are not yet active in every account; for Spain, the ordinary courts are still missing.
Answers from Dossiers remain suggestions that you review legally.
