Check text before it goes into an LLM
Text pasted into a large language model can end up memorised or exposed, so checking it first matters. This tool scans text for data that is likely to be sensitive, credentials, personal data, internal identifiers, so you can catch it before it reaches a model.
Why this matters for LLM use
Anything you send to an external model leaves your control, and sensitive data in a prompt can be logged, used in training, or surface in another user’s output. The risk is easy to create by accident, pasting a whole document that happens to contain a secret. Scanning the text first for the patterns of sensitive data lets you redact before you send, which is far safer than hoping nothing slipped through. This is a defensive check on your own inputs.
Catch it before you send
The tool runs entirely in your browser, so nothing you paste, prompts, outputs or documents, is uploaded, which matters when the input is sensitive AI data or your own content.

Frequently Asked Questions
Why check text before sending it to an LLM?
Because anything sent to an external model leaves your control and can be logged, used in training, or surface elsewhere. Sensitive data should be caught first.
What kinds of data does it flag?
Patterns likely to be sensitive: credentials, personal data and internal identifiers that should not be sent to an external model.
How does sensitive data get exposed by an LLM?
Through logging, inclusion in training data, or memorisation that surfaces in another response. Redacting before sending removes the risk.
Is this a scan of the model?
No. It scans your own input text before you send it, so you can redact sensitive data first.
Is my text uploaded?
No. The scan runs entirely in your browser.
