Nullgen recognizes the prompt box on ChatGPT, Gemini, Claude, Copilot — plus any new AI tools — and stops typing and pasting. The rest of the page keeps working.Staff and students can request temporary or permanent access to a tool — approved exceptions in the open, instead of hidden workarounds.The toolbar popup shows pending, approved, and denied requests.Requests reach named approvers with the site and duration — never the prompt — and unblock the moment they’re approved.Per-site allow and deny rules for specific people, synced to every enrolled browser in real time.Force-install through Intune, Jamf, Google Workspace, or Group Policy. Pinned, so the person at the keyboard can’t remove it.Family, school, or company — see every enrolled browser and who it belongs to.
关于此扩展
Stop AI prompts from being typed on any website.

Nullgen is an AI blocker suite for browsers, desktops, and mobile devices. The Nullgen AI Blocker browser extension 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.
