Nullgen AI Blocker is a parental-control and content-blocking app for families, schools, and workplaces. It stops AI chatbots and AI websites from working on this iPhone or iPad — in Safari, Chrome, and the apps themselves. Set it up once and it stays on. PART OF THE NULLGEN AI BLOCKER SUITE • Browser extension for Chrome, Edge, Firefox, and Safari — detects AI prompt boxes on any website and stops typing and pasting into them, on the device. • iPhone and iPad app (this app) — blocks known AI apps and websites across most websites and apps on the device. • Mac app — the same protection for Safari on the Mac. One Nullgen Pro account covers every device, with the same rules and the same approvals everywhere. WHAT IT BLOCKS ChatGPT, Gemini, Claude, Copilot, Grok, Perplexity, DeepSeek, Character.AI, Poe, Midjourney, and more than 70 other AI services. The list is kept up to date by Nullgen so new tools are covered without an app update. HOW IT WORKS To work, the app asks iOS for permission to add a VPN configuration. That configuration is used only to filter AI destinations on this device. It is not a traditional VPN: your traffic is never routed through Nullgen or anyone else, and nothing you browse is sent to our servers. When an app or browser tries to reach a known AI destination, the request is answered on the device and simply does not load. Everything else works normally. NO OFF SWITCH There is no button in the app to pause or disable blocking. That is the point: the person holding the phone is often not the person who installed it. FREE FOR 3 DAYS Start the trial with no account and no card. It lives on this device. When it ends, protection continues with Nullgen Pro. NULLGEN PRO — FAMILY Subscribe in the app, then link this iPhone or iPad to your Nullgen account at nullgen.ai/link. From there a parent can: • Approve or deny access requests. A child taps “Request AI access”, picks the tool and how long they need it, and the parent approves from the Nullgen dashboard. The tool unblocks instantly for exactly that time — fifteen minutes, an hour, a day, or permanently. • Set allow and deny rules per AI tool for each child. • Cover every device in the household: browser extensions for Chrome, Edge, Firefox, and Safari, plus the iPhone, iPad, and Mac apps, under one subscription. NULLGEN PRO — EDUCATORS AND ENTERPRISE Schools and companies deploy Nullgen across managed devices and route AI access requests to named approvers. Learn more and sign up at nullgen.ai. PRIVACY • Blocking decisions are made on the device. • Nullgen never receives which sites you visit or what you type. • The free trial creates no account. • Access requests contain only the tool, the duration, and an optional note you write. • Nullgen does not sell, share, or disclose any data from this app to third parties, and does not use it for advertising. Privacy Policy: https://nullgen.ai/privacy WHAT IT DOES NOT DO AI features built into services that share ordinary hosts — such as AI answers inside a search engine or a social app — are not blocked separately, because blocking them would block the whole service. On a personal, unsupervised iPhone, iOS still allows the VPN configuration to be removed in Settings; that is an operating-system limit. SUBSCRIPTION TERMS Nullgen Pro Family is offered as a monthly or yearly auto-renewing subscription, billed through your Apple account. Payment is charged at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel in Settings › Apple Account › Subscriptions.
