Scrub the prompt before you paste it into an AI
The fastest way to leak a customer email or an API key is to paste a “full context” prompt into a model. Assistants are hungry for examples, and examples are where the secrets live. A prompt privacy checker is a pause: scan the text, see what looks like personal data or credentials, and copy a redacted version into the chat you actually use.
Why this is worth doing in the browser
People mean to anonymise and then leave a JWT in the stack trace. The DevNestro AI Prompt Privacy Checker looks for common sensitive patterns and offers a safer rewrite you can paste. It is not a guarantee that every secret is found, and it is not a substitute for never putting production data in a prompt. It is a second pair of eyes before the text leaves your desk.
How to use the tool
Paste the draft prompt, review the findings, and copy the cleaned version. Use Privacy Redactor when you have a longer document that is not shaped like a prompt. Use Scam Checker when the question is whether a message you received is trying to steal from you.
- Paste the full prompt you were about to send, including logs and samples.
- Read each finding; patterns can both miss and over-flag.
- Replace real identifiers with the suggested placeholders.
- Send only the cleaned prompt to the model you chose.
Privacy
Scanning runs in your browser. Prompt text is not uploaded to DevNestro to train a model, and there is no account history of prompts.
Treat a prompt like a postcard. Open the AI Prompt Privacy Checker, strip the secrets, and then talk to the model.
