Frequently Asked Questions
What types of sensitive data does this tool detect?
∨
The tool detects: API keys (OpenAI, Anthropic, Google, AWS, GitHub, etc.), email addresses, phone numbers, credit card numbers, IP addresses, URLs, SSN patterns, and custom patterns you define.
Is my text uploaded to any server?
∨
No. All detection and replacement happens entirely in your browser using JavaScript. Your text is never sent to any server, stored, or transmitted. This makes the tool suitable for confidential prompts and sensitive data.
Can I add custom detection patterns?

Yes. You can add custom regex patterns to detect specific sensitive data formats unique to your organization. The tool supports regular expressions for flexible pattern matching.
What replacement options are available?

Default options include [REDACTED] and [MASKED]. You can also specify custom replacement text. The tool preserves the original text structure while replacing only the sensitive parts.
Does this work with non-English text?

Yes. The tool works with any text language. Detection patterns for API keys, credit cards, and email addresses are language-agnostic. Phone number detection supports international formats.
Can I use this for code files?

Detection is based on regex patterns and is highly accurate for common formats. However, it may miss obfuscated or non-standard formats. Always review detected items before sanitizing.
