How to stop data leaks in ChatGPT
ChatGPT is the most widely used AI assistant in the world, which also makes it the most common destination for accidental data leaks. Employees paste code, customer records, and credentials into it every day, often without realizing the data leaves company control. LeakSnitch watches this surface locally so sensitive data never reaches ChatGPT.
Short answer
ChatGPT is an AI platform from OpenAI. LeakSnitch scans text inputs, file uploads, and drag and drop content on chatgpt.com with publicly auditable patterns, and blocks or redacts sensitive data before the request is submitted. Detection runs entirely on the device and takes under 50 milliseconds.
The most common ChatGPT leaks
- API keys and tokens pasted while debugging code
- Customer PII pasted for summarization or rewriting
- Internal documents uploaded for quick analysis

Frequently asked questions
Does LeakSnitch work on ChatGPT for free?
Yes. The free individual tier includes full detection on ChatGPT and every other supported platform, with no limits on the number of AI tools you use.
Can ChatGPT read data LeakSnitch blocks?
No. LeakSnitch intercepts the submission before it is sent, so blocked or redacted data never reaches ChatGPT, its provider, or third parties.
Is ChatGPT usage monitored without permission?
LeakSnitch only activates on the text you type into supported AI platforms. It never reads browsing history, other sites, or content outside the AI page. In enterprise deployments, admins set the policy and users see every detection in the modal.
