FAQ
What does Nullgen AI Blocker do?
Nullgen AI Blocker prevents AI chatbots and AI websites from functioning on your iPhone or iPad. It blocks access to over 70 AI services across Safari, Chrome, and other apps by using a local VPN configuration to filter AI destinations on the device.
How does Nullgen AI Blocker work?
The app requests permission to add a VPN configuration to iOS. This configuration is used solely to filter AI destinations on your device. Your traffic is not routed through Nullgen, and browsing data is not sent to their servers. When an AI destination is detected, the request is answered locally, preventing the site or app from loading.

No, there is no off switch in the app to pause or disable blocking. This is a deliberate design choice to ensure continuous protection, especially when the device is used by someone other than the installer.
