AI Prompt Privacy Checker — Remove Sensitive Data Before ChatGPT, Claude, or Gemini

How to Use

1. Paste or type your text into the box — a prompt, an email, a document, or anything you want to check.
2. Click Scan for sensitive info. The tool scans your text and automatically replaces anything it finds with labels.
3. Review what was redacted in the panel below — you can see what each item was, grouped by type such as email, phone, or ID.
4. If the scanner replaced something it shouldn't have, click Restore next to that item to put the original text back.
5. Use the label buttons to manually label anything the scanner missed — highlight the text and click a label like [NAME] or [ID].
6. Click Copy and paste the cleaned text into your AI assistant.

Common Use Cases

• Customer support: sanitize customer email before AI by replacing names, emails, phone numbers, account IDs, ticket numbers, and internal notes with stable labels before asking for a draft reply.
• Developers: you want AI help debugging an error but your log file contains API keys and server addresses. Scan the log first — credentials and internal addresses are replaced automatically before you paste.
• HR teams: you're using AI to help review or summarise candidate documents that include ID numbers or dates of birth. Scan the document before pasting to remove those details.
• Legal and compliance: you need AI to help draft or review a document that mentions client reference numbers or financial details. Scan it first so those details are replaced with labels the AI can still work around.
• Healthcare: you want to use AI for admin tasks like summarising notes, but the notes include patient ID numbers or dates of birth. Scan the text first to remove identifying details.
• Finance teams: your invoices or bank statements include card numbers or account details. Scan them before sharing with AI to replace financial information with safe labels.
• Anyone using AI at work: if the text you're about to paste into an AI chat came from a work system — a CRM, HR tool, or case management app — scan it first to catch personal data you might have missed.

When to Use This Tool

• Before pasting any text into ChatGPT, Claude, Gemini, or Copilot that might contain names, phone numbers, email addresses, or other details about real people.
• Before using AI to help reply to a customer email, summarise a meeting, or write a message that references someone by name or contact detail.
• Before sharing work documents, case files, or medical notes with an AI — even if you think you've already removed the sensitive parts, a quick scan can catch anything you missed.
• Before pasting debug logs, code files, or settings into an AI code assistant — these often contain API keys, passwords, or internal server addresses that shouldn't leave your systems.
• If your company or industry requires you to keep personal data private under rules like GDPR or HIPAA, use this tool before any AI processing to remove identifying details first.
• Any time you copy text from a work tool — a customer database, HR system, or finance app — and want to paste it into an AI chat window.

Limitations

• Names written in normal sentences won't be detected. If your text says "I spoke with Sarah Johnson about this", the scanner won't catch "Sarah Johnson" — use the manual label buttons to highlight and replace names like that.
• A phone number or ID that appears alone with no label nearby may be missed. Numbers are easier to spot when there's a word like "Tel", "SSN", or "Account" nearby to confirm what they are.
• The scanner looks for standard formats. If a number is split across lines, heavily abbreviated, or written very differently from its usual format, it might not be caught.
• Only English-language data formats are supported. Phone numbers, ID formats, and addresses that follow the conventions of other countries or scripts may not be detected.
• The scanner matches patterns, not meaning. A phrase like "the patient born in 1985" won't be caught — only a date written as an actual date value will trigger the date-of-birth detector.
• Always do a final read-through. No automated tool catches everything — read the cleaned text once more before pasting it into an AI chat.

Quality and Accuracy Notes

• Each result shows a confidence level — "Very high" means the scanner is almost certain (the value passed a built-in check, like verifying a credit card number follows the correct rules). "High" or "Medium" means it looks right but couldn't be fully confirmed — review those before keeping the replacement.
• If the scanner removed something it shouldn't have, click Restore next to that item. This puts the original text back without affecting anything else that was redacted. You can restore one item, a whole group, or everything at once.
