How to Use AI Prompt Secret Sanitizer & Data Redactor

1

Paste Sensitive Code, Config, or Prompt

Paste your source code, .env file, database URI, or system prompt into the editor. Or import a file directly.

2

Choose Protection Profile & Style

Select Full Enterprise DLP, API Keys Only, or PII Only. Choose Synthetic Identifiers (<REDACTED_*>) for bidirectional unmasking or Asterisk Masking.

3

Copy with LLM Preservation Note

Click 'Copy for ChatGPT / Claude' to include instructions telling the AI to preserve placeholder tokens verbatim in its response.

4

Unmask AI Response Locally

Paste the response returned by Claude or ChatGPT into the 'Unmask AI Response' tab. Your genuine credentials and database URIs are restored instantly in memory.

Pro Tips
Use Synthetic Identifiers when you want to restore original values after the AI responds.
Use 'Copy for ChatGPT / Claude' to prepend instructions ensuring the AI leaves your <REDACTED_*> tags intact.

Practical Examples & Conversions

Input
export OPENAI_API_KEY="sk-proj-abc12345..."
export DATABASE_URL="postgres://admin:pass@db.prod.internal:5432/main"
Output
export OPENAI_API_KEY="<REDACTED_OPENAI_KEY_1>"
export DATABASE_URL="<REDACTED_DB_CONNECTION_STRING_1>"
