AI Privacy.
Simple.
SOWA Privacy is a Chrome extension that detects and replaces sensitive data in your prompts before they reach ChatGPT, Claude, Gemini, or other AI tools. Detection runs locally in your browser; only the placeholder-replaced prompt is forwarded to the AI provider you choose.
The AI Compliance Dilemma
Employees use ChatGPT & Co. – but entering highly sensitive data poses enormous legal risks.
Data Leakage
Personal data, health information, or contract contents end up with international AI providers in third countries.
GDPR Violations
Lack of control over Art. 9 GDPR data leads to incalculable compliance risks and potential penalties.
Shadow IT
A complete AI ban drives users into unregulated gray areas; internal infrastructure projects often fail due to complexity.
