Stop AI prompts before they are submitted. On-device protection for work, school, and home on any website. Stop AI prompts from being typed on any website. Nullgen AI Blocker is a lightweight, zero-configuration extension that intercepts unauthorized generative AI inputs directly at the keyboard level. Designed to combat Shadow AI, Nullgen provides always-on protection for work, school, and home. Whether you are an enterprise securing proprietary company data, an educator enforcing academic integrity, or a parent managing household screen habits, Nullgen delivers real-time blocking without restricting access to entire domains—websites remain fully usable, just with their generative AI features disabled. Core Features (Free) Real-Time Prompt Interception: Instantly block text inputs on major generative AI interfaces (including ChatGPT, Claude, Gemini, Copilot, and custom web wrappers) using a seamless in-line overlay. 100% On-Device Processing: Your text never leaves your computer. Nullgen analyzes prompts locally to guarantee absolute privacy and security. Zero-Account Required: Install the extension and it instantly begins blocking AI inputs right out of the box—no setup or configuration needed. Nullgen Pro (For Enterprises, Educators, and Families) Upgrade to a managed plan to unlock centralized administration, zero-touch deployment, and granular access controls. Centralized Policy Management: Manage access gate policies across your entire fleet from a secure web dashboard. Easily configure rules to grant users temporary or permanent access to specific AI websites. Permission Request Workflows: Users can request temporary or permanent access to specific AI tools directly through the blocked UI. Requests are routed instantly to an assigned admin, teacher, or parent for one-click approval. Zero-Touch MDM Provisioning: Automatically force-install and seamlessly enroll fleet devices via Group Policy (GPO) or MDM tools like Microsoft Intune, Jamf, Kandji, and Google Workspace. Device Enforcement & Lockdown: Apply a system-level policy to permanently pin the extension in the browser so it cannot be disabled, removed, or bypassed. This enforcement simultaneously disables native, built-in browser AI features and private browsing modes for comprehensive, airtight protection. Privacy First by Design Nullgen is built on the strict principle of zero-trust data collection. The core extension engine operates entirely locally. Your prompt history, inputs, and keystrokes are never stored, transmitted, or analyzed on external servers.
