Nullgen AI Blocker ავტორი Nullgen

Stop generative AI data leaks and enforce usage policies before a prompt is ever submitted.

Nullgen AI Blocker is a lightweight, zero-configuration browser extension that intercepts and blocks generative AI prompts directly at the keyboard level. Whether you are an enterprise securing proprietary company data, an educator enforcing academic integrity, or a parent managing household screen habits, Nullgen provides real-time protection without compromising browser performance.

Core Features (Free)
Real-Time Prompt Interception: Instantly blocks flagged text inputs on generative AI interfaces (like ChatGPT, Claude, and Gemini) using a seamless in-line frosted glass overlay.

100% On-Device Processing: Your text never leaves your computer. Nullgen analyzes prompts locally to guarantee total privacy.

Live Impact Metrics: Track your daily and all-time blocked prompts directly from the extension popup.

Zero-Account Required: Install and instantly start protecting your data with a global master toggle.

Nullgen Premium (For Families, Educators, and Enterprises)
Upgrade to a managed plan to unlock centralized policy control and advanced reporting:

Permission Request Workflows: Users can request temporary or permanent access for specific prompts directly through the blocked UI, routing instantly to an assigned admin or parent for approval.

Centralized Policy Management: Deploy custom prompt filters, blocked keywords, and daily usage limits across multiple devices from a secure web dashboard.

Enterprise MDM Provisioning: Automatically deploy policies and enroll fleet devices via standard Mobile Device Management (MDM) tools.

Secure Manual Provisioning: Easily link client devices using time-limited, 6-character single-use setup codes—keeping admin credentials entirely off end-user machines.

Privacy First by Design
Nullgen is built on the principle of zero-trust data collection. The core extension operates entirely locally. Your prompt history and keystrokes are never stored, transmitted, or analyzed on external servers.
