Bidirectional workflow support. Sanitize data for prompts, then decode AI responses to restore original values. Reversible data obfuscation at its finest.
Completely free data masking tool. No sign-up, no installation, no limits. Open the page and start sanitizing instantly.
Export sanitization rules as JSON. Share with your team to enforce consistent data anonymization methods across projects.
Data masking is a security technique that creates a structurally similar but inauthentic version of sensitive data. It protects information while providing a functional alternative for use cases like training, demos, or testing. This tool provides dynamic data masking capabilities directly in your browser.
Data anonymization removes or encrypts personally identifiable information (PII) from datasets so individuals remain anonymous. Critical for privacy compliance (GDPR) and safe data sharing. This tool serves as free data anonymization software you can use instantly.
Most data masking tools are complex, expensive, and require server uploads. This tool is unique: 100% browser-based (data stays with you), free, and specifically designed for modern AI workflows with bidirectional encoding/decoding support.
Common data masking techniques include tokenization, generalization, pseudonymization, and data obfuscation. This tool uses intelligent pattern detection to replace sensitive data with human-readable tokens. Use this as data anonymization software for securing prompts, logs, and documents.
Data masking replaces sensitive data with realistic but fake values, while tokenization substitutes data with unique tokens. This tool combines both approaches, creating human-readable tokens that maintain context for AI analysis while protecting original values.
Yes. This tool provides automated data anonymization by intelligently detecting repeated patterns in your text. Simply paste your content, click Analyze, and the tool will identify sensitive patterns for instant anonymization, no manual configuration required.
