How it works: Executes high-speed regular expression matching, tokenization, replacement, and redaction over arbitrary text documents and system logs. Features one-click presets for common Personally Identifiable Information (PII) including email addresses, IPv4 addresses, telephone numbers, credit card numbers, and UUID/GUID identifiers. Provides four actionable processing modes: intelligent partial masking (which preserves context like domain names or card last-4 while masking sensitive user identifiers), full redaction ([REDACTED]), custom string replacement with standard regex capture group substitution, and read-only visual inspection. Live anomaly diagnostics report exact match frequencies, unique matched values count, and syntax error alerts if an invalid custom expression is provided.
Why it matters: Sharing application logs, stack traces, database dumps, or support tickets with external AI models, vendor support desks, or team chat channels frequently risks accidental disclosure of sensitive credentials, customer emails, internal IP addresses, and financial account numbers. Compliance frameworks such as GDPR, HIPAA, and PCI-DSS mandate strict sanitization of confidential data before sharing or public archiving. Manually scanning thousands of lines of log output is virtually impossible and error-prone. PasteXray visually highlights every pattern match with distinct colored badges in the X-Ray inspection pane, showing the exact before-and-after transformation in real time. Because all processing executes in browser memory, your confidential documents are never transmitted across external networks.
Security Architecture: All regular expressions execute locally in your browser sandbox with zero network telemetry.
