Challenges law firms are facing in embracing AI

Why ChatGPT, Copilot, and generic AI tools aren't built for law firms.

Shadow AI in the Law Firm

Lawyers use ChatGPT via private accounts. Client data flows uncontrolled into US clouds. No traceability, no audit trail.

Professional Ethics Risks

Attorney-client privilege (§43a BRAO) demands full control over client data. Cloud AI without EU hosting violates this obligation.

No Word-Native Output

AI tools generate plain text or PDFs — not formatted Word documents. Lawyers waste hours reformatting drafts to match firm templates, styles and numbering conventions.

Exploding Costs

Seat-based pricing: €29/user/month with ChatGPT Business. With 50 lawyers over €17,000/year — without control over usage and quality.

No Process Automation

Consumer chat tools are built for single conversations. No workflow system, no integration with legal software, no legal skills.

Audit & Traceability Risk

No audit trail, no oversight of what AI generated what content. Regulatory exposure in client matters where AI contribution cannot be documented.

The AI adoption challenge from 2 different perspectives

"Mandatsbearbeitung" and "Kanzleiführung" needing the same tools for different purposes.

Bottom-up Mandatsbearbeitung

Case teams easily set up projects, connect relevant context like emails and meeting notes, perform case research, and draft legal documents in one tool.

  • Word-native content and formatting editor
  • Project based RAG setup
  • In context research support
  • Prompt library with templates
Top-down Kanzleiführung

Firm management can easily update firm playbooks, set formatting norms, retrieve the most relevant past cases and templates while easily managing data protection, usage, and costs.

  • Firm templates, RAG, and skills management
  • BORA and BRAO compliant deployment and DPAs
  • European hosted
  • Billing & audit automatic

Why Klaus is right for your firm

The central AI workspace — not just a chat tool.
