Here you will find answers regarding our generative AI capabilities for your legal practice, including questions  about security, features, and subscription plans.

 

General Overview

  • What is Wolters Kluwer Expert AI?

     
    Expert AI is Wolters Kluwer’s specialised generative AI for legal solution, integrated directly into Kleos. Grounded in over a decade of innovation, it combines deep domain expertise with responsible AI principles to help legal professionals work more strategically.

    We have designed Expert AI to streamline your workflows and enhance your expertise. It empowers you to deliver greater impact across the legal landscape by allowing you to work faster and smarter within a secure environment.
  • What is the difference between Kleos Expert AI and other AI tools like ChatGPT?

    Unlike general-purpose models, Kleos Expert AI is tailored specifically for the daily needs of legal professionals. While generic tools lack industry-specific context, Kleos offers specialized features designed for law firms, including document summarisation, search, analysis and comparison with AI.

    We are also expanding its capabilities to support case management with AI and a broader range of activities to improve productivity at the firm level. 

Subscription and pricing

 
  • If we buy or already pay for a Kleos license, is Expert AI included?

Security and Privacy

 
  •  How are prompts and results stored during document comparison?

    When you compare documents, all prompts and results are stored securely within your Kleos system to guarantee confidentiality and provide easy access for future reference.

    Your documents are treated with the highest level of security. They are shared with no one and are used only to answer your questions. Once the session is over, the data is not retained for other uses.
  • Is my data used to train the public AI model?

     
    No, your data remains private. Wolters Kluwer adheres to strict responsible AI principles. Your client data and documents are never used to train the public models of our technology partners, ensuring your firm maintains full confidentiality and compliance.

Capabilities and Features

 
  • Does the AI understand regulations and laws?

     
    The AI searches, synthesizes, and compares information contained within the documents you process, but it does not replace legal judgment. Think of it as a highly efficient assistant that helps you find what you need in seconds, without requiring you to read an entire document word-for-word.
  • Which file formats does Kleos Expert AI support?

     
    Kleos Expert AI supports a wide range of file formats to streamline your workflow. You can analyze documents, emails, and even images directly within the Kleos interface, eliminating the need for conversions.
    The specific formats supported include:
     -Text documents: .doc, .docx, .pdf, and .txt.
     - Emails: .eml and .msg, with the AI identifying recipients, sender, subject, body text, and any attachments.
     - Images: .png, .jpg, .jpeg, .webp, and .gif.
    To ensure efficiency, Kleos Expert AI can process up to five documents simultaneously, in addition to emails and their corresponding attachments. The AI assistant is only enabled for these specific file types.
  • Does a document need to be machine-readable (OCR) for AI to process it?

    Yes, documents must be optical character recognition (OCR) compatible. The AI requires machine-readable text to perform analysis, summarization, or extraction tasks effectively.
  • Does Kleos Expert AI have limits regarding document size or number of pages?

    Yes, there are operational limits to ensure speed and performance. The system cannot process documents that exceed 6 MB. Additionally, for email processing, the tool does not currently allow for multiselection of emails; they must be processed individually.
  • Can I already apply Kleos Expert AI to the financial data in files?

    Not yet. We are currently working on developing Expert AI for case management within Kleos, which will provide financial analysis capabilities. 
  • Is legal terminology properly aligned when translating between languages?

    Yes, the AI is generally effective at translating legal terminology. However, for unusual or highly specific legal concepts, there may be slight misalignments. We recommend reviewing translations for accuracy regarding specific jurisdictional terms.
