Before you paste
AI tools do not forget
Dropping a spreadsheet or document into an AI assistant is convenient, and irreversible. Once sensitive data leaves your machine for a third-party model, you cannot pull it back.
FileSentinel scans the file first, on your own PC, and flags the SSNs, payment cards, account numbers, health data, and credentials you would not want to share with a chatbot, so you can redact them before you paste.
What to catch first
Data you should never paste into AI
| Category | Why it matters |
|---|---|
| Personal identifiers | SSNs, IDs, and DOBs can identify real people |
| Payment & financial | Card and account numbers enable fraud |
| Credentials & keys | Passwords and API keys grant access |
| Health information | PHI is regulated and sensitive |
A pre-flight check
Redact, then share with the model
Run FileSentinel as a quick pre-flight check before using AI. Redact the sensitive values to a clean copy, then paste that. The model gets what it needs; the sensitive data stays with you.
- Local pre-check
- Redact to clean copy

FAQ
Why scan a file before sending it to ChatGPT?
Once you paste content into an AI tool, it has left your control. Scanning first lets you catch and redact sensitive data so you do not hand it to a third-party model by accident.
Does FileSentinel itself use the cloud or AI?
No. FileSentinel scans entirely on your device with no uploads, so checking a file does not send it anywhere.
What should I redact before using AI?
Personal identifiers, payment and account numbers, credentials and API keys, and health information. FileSentinel finds and helps you redact all of these.
Can I keep a clean copy to paste?
Yes. FileSentinel redacts sensitive values to a clean copy you can safely share with an AI tool, leaving the original intact.
