ChatGPT Data Leak Prevention
How to Prevent Data Leaks in ChatGPT
The fastest way company data leaves today is a copy-paste into ChatGPT. There is no undo button on a prompt. StileAI checks every message before it is sent and stops the ones that carry secrets, customer data, or source code, without banning ChatGPT for your team.
The one-keystroke leak
An employee drops a customer spreadsheet in to "clean it up," pastes a stack trace that contains a live API key, or shares a contract to summarize. It feels harmless and it takes one second. None of it shows up in your normal security stack, because the chat box is invisible to it.
Block the leak, keep the tool
Banning ChatGPT does not work: people use it anyway on personal accounts, where you have zero visibility. The better answer is a checkpoint. StileAI installs as a browser extension for ChatGPT, Claude, and Gemini, checks each prompt in the browser in about 40 milliseconds, and only stops the ones that break your policy.
- ▸Real secrets and against-policy content are blocked before they leave.
- ▸Borderline requests are held for a quick admin approval.
- ▸Safe prompts go straight through, so nobody's workflow slows down.
See what your team is really sending
Turn on monitor mode for your first two weeks and StileAI logs what would have happened on every prompt without blocking anything. Most teams are surprised how much sensitive data is going out. Then flip to enforce with your eyes open.
Frequently asked questions
How do I stop employees pasting sensitive data into ChatGPT?
Put a checkpoint in front of ChatGPT. StileAI's browser extension checks each prompt against your policy and blocks or holds anything with secrets, PII, or source code before it is sent, while letting safe prompts through.
Will it slow my team down?
No. The check takes about 40 milliseconds and only interrupts the small fraction of prompts that actually carry sensitive data.
Can I try it without blocking anyone?
Yes. Monitor mode logs what would have happened on every prompt for a window you choose, so you can see your environment before enforcement is turned on.
Does it work on the ChatGPT website?
Yes, through a Chrome extension for ChatGPT, Claude, and Gemini on the web. For desktop and dev tools, a one-line gateway setup covers the OpenAI and Anthropic APIs.
