What this tool does
Logs contain the exact details needed for debugging, which is also why they frequently expose credentials, customer identifiers, internal paths, and infrastructure names. A useful sanitized log keeps error messages, timestamps, package names, status codes, and relevant stack frames while removing access-bearing values.
If a real secret has already been shared, redaction is not enough. Revoke or rotate it in the service that issued it.
Recommended workflow
- Work from a copyKeep the original log private and sanitize a duplicate intended for sharing.
- Scan for credentials firstCheck Authorization headers, environment variables, connection strings, JWTs, and vendor-specific key prefixes.
- Preserve the error pathKeep the exception, package versions, relevant stack frames, request method, and response status where safe.
- Rotate exposed secretsRevoke any credential that left an approved system, even if you later delete or edit the message.
What it checks
The current tool version is designed to handle the following areas:
- Bearer tokens
- JWT-like values
- API-key assignments
- AWS-style access key IDs
- database connection URLs
- email addresses
- IPv4 addresses
- URLs
- file paths
- common IDs
Example
Before
ERROR user=ali@example.com Authorization: Bearer abc.def.ghi DATABASE_URL=postgres://admin:secret@db.internal/appSafer output
ERROR user=[EMAIL] Authorization: Bearer [SECRET] DATABASE_URL=[SECRET]Safety checks before sharing
- Search manually for password, token, secret, auth, key, cookie, and session
- Remove internal domains and user-specific file paths
- Check pasted request and response bodies
- Review screenshots separately
Representative test coverage
This page is checked with representative examples, not every possible format or file produced by every application.
- Node.js stack traces
- browser console output
- web-server logs
- .env-style snippets
- API error responses
Known limitations
Automated processing can miss unusual formats, indirect identifiers, hidden data, unsupported structures, and information that requires human judgment. This tool may miss:
- custom secret formats
- base64-encoded secrets
- private hostnames without a URL
- credentials split across lines
- secrets inside screenshots or archives
Do not describe the result as fully anonymous, legally compliant, secure, or impossible to re-identify. Review the exact final artifact before sharing it.
Frequently asked questions
Does Log Sanitizer for ChatGPT upload my input?
The normal tool workflow runs in your browser. The page code is downloaded from the website, but the content you paste or select is processed locally and is not sent to a Privacy Toolbox processing API.
Can this guarantee complete anonymization?
No. Automated checks can miss context clues, unusual identifiers, text inside unsupported files, and details that only a person would recognize. Always review the result before sharing.
Should I use this for regulated or highly sensitive data?
Only when your organization permits it. For medical, legal, financial, employment, or customer data, follow your approved security and compliance process rather than relying on a free pattern-based tool alone.
