The Journey of Your Secrets
See how your sensitive data travels and how we protect it
1. The Copy-Paste Moment
Someone copies sensitive data (API keys, credit cards, personal info) ready to paste it into ChatGPT for "help".
2. The AI Feast
The AI model gobbles up your sensitive data, storing it in its training data. Now it knows your secrets better than you do.
3. The Data Leak
Your sensitive data becomes part of the AI's knowledge base, potentially accessible to anyone who knows how to prompt it right.
4. The LeakSnitch Save
But wait! LeakSnitch detects the sensitive data and blocks it faster than you can say "Oops, I shouldn't have done that."
Ship prompts without leaking secrets
LeakSnitch monitors and blocks API keys, tokens, sensitive text, and scans files before they reach AI tools. Add it to your browser and relax.
