What is PhantomPaste?
A privacy-first text redaction tool that automatically detects and masks sensitive information. All processing happens in your browser - your data never leaves your device.
Invisible Track
Zero data retention. Your text vanishes like a ghost after processing.
Client-Side Only
All processing happens locally in your browser for maximum security.
Lightning Fast
Instant redaction with intelligent pattern recognition algorithms.
Smart Detection
Automatically identifies emails, phones, SSNs, and more sensitive data.
How Does It Work?
Three simple steps to secure your sensitive data before sharing
Paste Your Text
Copy and paste your document containing sensitive information. PhantomPaste automatically scans for patterns like emails, phone numbers, SSNs, credit cards, and more.
Configure & Process
Review detected patterns and customize replacements. Lock specific fields to prevent changes, or regenerate fake data with a single click. Then process your text.
Export & Share
Download your masked text and mapping file. Share the masked version safely with AI tools or colleagues, and use the mapping to restore original data later.
Reversible Masking
Unlike permanent redaction, PhantomPaste creates a reversible mapping. Use the Unmask feature to restore your original text anytime using the stored mapping or downloaded JSON file.
