100% Mandantenvertraulichkeit durch lokale Verarbeitung
Keine API-Limits oder Cloud-Abhängigkeiten
Einmalige Investition statt laufender Token-Gebühren
Many law firms work daily with highly sensitive client data, confidential briefs and extensive precedent case libraries. Cloud-based AI solutions carry risks for data protection, client confidentiality and compliance.
With AI Cube, your AI infrastructure remains completely on your own network – your data doesn't leave the premises, and you retain 100% control over software, models and access. Additionally, you avoid ongoing token or API costs and are not dependent on external providers.
Your data never leaves your firm's network
No API limits, no external updates, no vendor lock-in
Local inference with minimal latency reduces wait times for users
One-time investment instead of ongoing payments
How AI Cube supports your law firm in daily operations
Through semantic search, make your internal case files and judgment collection quickly and efficiently searchable. AI Cube identifies relevant judgments, legal provisions or briefs, provides argumentation building blocks and saves valuable working time.
Automatically create initial drafts for expert opinions, client letters or statements – tailored to your firm's language and requirements. Final control remains with the attorney, but the preliminary work is already done.
Transform your firm's experience into a searchable knowledge platform: New employees quickly find answers to typical cases, your solutions are documented and available at any time – without cloud access, directly in-house.
