Hey Product Hunt! 👋
I’m Philippe, the creator of ChatWall.
A few weeks ago, I was auditing the network traffic of popular AI chatbots and discovered something that completely blew my mind (and terrified me as a privacy advocate).
ChatGPT and Grok gets your partial prompts before you even hit send. 🤯
If you accidentally paste an API key, customer PII, or an IBAN, and quickly delete it before submitting... it’s already too late. The frontend event listeners have already synced your draft to their servers.
I couldn't find a tool that actually prevented this at the browser level, so I built one.
🛡️ Use ChatWall - The AI Privacy Firewall. https://chatwall.io
ChatWall is an open-source browser extension that physically isolates your chat inputs. It injects a closed Shadow DOM over the chat input, preventing the host page's JavaScript from reading your keystrokes until you explicitly click "Send Masked"
Isolated : Blocks real-time keystroke logging (zero-day leak protection).
Local : Works 100% locally in your browser.
Transparent : Open Source (Audit the code yourself!).

I’ll be hanging out here all day! I’d love to hear your feedback. Let me know what you think! 👇
