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. Once the AI responds, these safe placeholders are automatically restored to the original values Example: Before: "My name is John Smith, email john@example.com" After: "My name is PERSON_1, email EMAIL_1@masked.local" ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Smart Regex detection – 20+ types of sensitive data recognised out of the box: emails, phone numbers, credit cards, IBAN, SSN, PESEL, NIP, API keys, JWT tokens and many more • Local NER (Named Entity Recognition) model – catches names, addresses, dates, times and domain-specific data like medical codes, product names and legal terms • Power Mode (local LLM) – a fully local large language model, running right in your browser, for smarter, context-aware anonymization • Rules you control – whitelist trusted domains, blacklist sensitive terms and create your own custom regex patterns • Anonymize whole files – TXT, PDF, DOCX, XLSX and more • Built-in dictionary/audit trail – a full log of every anonymization event, ready for compliance reviews • Multi-language UI — English, German, Polish, French ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WORKS WITH YOUR AI TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • ChatGPT (chatgpt.com) • Claude (claude.ai) • Google Gemini (gemini.google.com) • Microsoft Copilot (copilot.microsoft.com) • Grok (grok.com) • Any website (configurable in settings) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY & SECURITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • All PII detection runs locally in your browser • No data is ever transmitted to SOWA Privacy servers • Open source – audit the code yourself: https://github.com/Sowa-Privacy/sowa-privacy-chrome-extension • GDPR-conscious by design ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS IT FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Public Sector, Healthcare, Finance & Legal, Industry & KRITIS professionals handling personal/sensitive data • All companies that need to stay GDPR-compliant while using AI tools • Anyone who values their privacy when chatting with AI
