Quick start

Features and use cases

Replace emails, key-like strings, and similar patterns with placeholders for safe sharing.

Use for community posts, GitHub issues, and internal docs—manually review production data too.

Typical Workflow

When sending prompts containing sensitive information to LLMs like ChatGPT, first paste the entire text into the tool. It instantly detects emails (e.g., [email protected]), API Keys (e.g., sk-abc123), and JWT tokens, replacing them with [REDACTED].

The processed text can be directly pasted into AI chat windows. We recommend cross-checking to ensure sensitive data is redacted while code logic and normal text remain intact. All processing happens locally in your browser, making it ideal for corporate or personal private data.

FAQ

Custom placeholder?

Fixed to [REDACTED]; edit manually if you need a custom token.

Does redacted text affect AI comprehension?

Generally no. LLMs rely more on contextual semantics than specific parameter values. But if redacted items are critical variable names (e.g., database fields), manually replace them with meaningful placeholders (e.g., [USERNAME] instead of [REDACTED]).
