FAQ

Frequently Asked Questions from Law Firms

Without additional safeguards, using ChatGPT in law firms is problematic because personal client data is transferred to servers in the USA. KI-Shield solves this by automatically detecting and pseudonymizing all personal data before the request is sent to the AI. This allows you to use ChatGPT, Claude, and other AI tools – fully GDPR-compliant.

If client data is transmitted unencrypted to AI providers like OpenAI, this may violate Section 203 Criminal Code (disclosure of private secrets) and the professional duty of confidentiality. KI-Shield automatically pseudonymizes all personal data before it leaves your law firm – the AI only sees anonymized placeholders.

All data is processed exclusively on German servers (Hetzner). No US Cloud Act, no FISA 702. The original data never leaves the proxy server in the EU. Additionally, KI-Shield uses a zero-knowledge architecture: Even the operator cannot read your data – everything is AES-256 encrypted.

The Free plan is permanently free (50 requests/month). All prices and plan details can be found on our pricing page.
