Type your message in any supported AI Chatbot 2. SOWA Privacy scans your input for personal/sensible data in real time and highlights any found PII 3. If any PII is detected, you will be interrupted by a pop-up window while trying to send your prompt to the AI Chatbot, press "Anonymize" to replace it with safe placeholders 4.
