Context-Aware Detection

Pattern matching catches known secrets instantly. Semantic analysis understands context to catch what patterns miss, all before data leaves your browser.

Smart Replacements

Mask, generate format-preserving dummies, or set custom replacements for each detection. Preview changes live before sending.

File Protection

Scan PDFs, spreadsheets, and 50+ file types. Download redacted versions or let Obfusca auto-upload the protected file back to the chat.

Policies & Visibility

Define rules in plain language, or write semantic rules that understand intent, not just keywords. See exactly what was caught, where, and why.

FAQ

Obfusca uses a two-phase detection engine: fast pattern matching with validation (SSNs with area/group checks, credit cards with Luhn, API keys, AWS credentials, private keys, and more) combined with AI-powered semantic detection that catches sensitive data regex misses, like spoken-out SSNs, partial card info, or confidential business metrics. All scanning runs in your browser before anything reaches the AI tool.
