Free Security Tool
Secure Log & PII Sanitizer
Remove sensitive data from logs before sharing with AI assistants or posting to public forums. Detects API keys, emails, credit cards, SSNs, and more. 100% client-side processing - your data never leaves your browser.
Sanitization Rules
Quick Usage Guide
1. Paste Your Logs
Copy error messages, stack traces, or log files into the input area. Supports up to 100,000 characters.
2. Choose Categories
Enable the types of sensitive data you want to redact. Healthcare/HIPAA patterns are disabled by default.
3. Copy Safe Output
Review the sanitized output, then copy it to safely share with AI assistants, forums, or colleagues.
Why Sanitize Logs Before Sharing?
What is PII?
Personally Identifiable Information (PII) is any data that can identify an individual. This includes names, email addresses, phone numbers, social security numbers, IP addresses, and financial information like credit card numbers.
AI Assistants & Training Data
When you share logs with AI assistants, that data may be used to improve models or stored in conversation history. Sanitizing sensitive data ensures your secrets and customer information don't end up in AI training datasets.
API Keys & Secrets
Accidentally exposed API keys are a leading cause of security breaches. AWS keys, Stripe tokens, database connection strings, and JWTs in logs can give attackers full access to your systems and customer data.
100% Client-Side Processing
This tool runs entirely in your browser. Your logs are never sent to any server. The sanitization happens locally using JavaScript regex patterns. You can verify this by disconnecting from the internet - the tool will still work.
