AI Prompt Redactor & PII Anonymizer (with Reversible Restoration)
Reversible AI PrivacyRedact personally identifiable information (PII), confidential API keys, and sensitive business data from AI prompts before pasting them into LLMs like ChatGPT, Claude, and Gemini. Replace sensitive entities with reversible placeholder tokens, copy the clean prompt, and restore original values into the AI response locally.
AI Prompt Redactor & PII Anonymizer (with Reversible Restoration)
Scrub client emails, phones, API keys, and IP addresses before pasting into ChatGPT with reversible de-anonymization.
Interactive AI Prompt Redactor & PII Anonymizer (with Reversible Restoration) Workspace
Protect confidential and client data before pasting text into ChatGPT, Claude, or Gemini. Anonymizes emails, phone numbers, API keys, and IP addresses with reversible placeholders ([EMAIL_1], [API_KEY_1]), and restores original data from AI responses in 1 click.
How This Tool Works (100% Client-Side Engine)
The tool runs client-side regex matching and entity detection routines across your text. Matched entities are assigned unique semantic tokens (e.g. {{PERSON_1}}, {{TOKEN_1}}) and recorded in an in-memory key-value map. The de-identification process replaces tokens with original values upon pasting the AI response.
Step-by-Step Guide
Paste Raw Prompt Text
Paste your prompt, code snippet, or customer inquiry containing sensitive data into the input workspace.
Inspect & Customize Detected PII
Review the automatically flagged emails, credentials, phone numbers, and names, toggling any custom entities you want masked.
Copy Redacted Prompt & Restore Later
Copy the sanitized prompt for your AI chatbot, then paste the AI reply back into the restore panel to reinject your real data.
Why Use This Tool: Privacy & Performance
Sending proprietary client data, employee social security numbers, private API credentials, or customer email addresses into public AI chatbots violates confidentiality agreements, GDPR data privacy rules, and internal corporate governance. Once entered into cloud AI prompts, sensitive data may be stored in chat logs, viewed by human reviewers, or incorporated into future training sets. ToolByte AI Prompt PII Scrubber provides an intelligent client-side redaction firewall. Operating purely within your local browser memory, it scans prompts using pattern-matching engines and regular expressions to identify emails, phone numbers, credit cards, IP addresses, AWS keys, JWT tokens, and names. It substitutes them with numbered token placeholders (e.g. {{EMAIL_1}}, {{API_KEY_1}}) and stores an encrypted mapping table in temporary RAM. You paste the redacted prompt into ChatGPT, paste the AI response back into ToolByte, and click restore to seamlessly reinject your real data locally.
