Nullgen AI Blocker
Overview
- Prevent proprietary company data, academic work, and personal information from ever entering an AI system with real-time prompt interception that blocks text inputs directly at the keyboard level on ChatGPT, Claude, Gemini, Copilot, and custom web wrappers.
- Keep every website fully functional while disabling only its generative AI features, using an in-line overlay that targets AI prompts without disturbing any other site functionality.
- Guarantee absolute privacy and data loss prevention because 100% on-device processing analyzes every keystroke locally, so prompt history, inputs, and sensitive data never leave the computer or reach external servers.
- Start blocking Shadow AI in under one minute with zero-account, zero-configuration setup that requires no signup, no data uploads, and no technical expertise.
- Stop students from submitting AI-generated work and uphold academic integrity by blocking input into AI prompts before they are sent, achieving immediate prevention instead of after-the-fact damage control.
- Manage AI access across an entire fleet from a secure web dashboard with centralized policy management, configuring granular rules that grant users temporary or permanent access to specific AI websites.
- Route permission requests instantly to an assigned admin, teacher, or parent through the blocked UI, enabling one-click approval workflows for temporary or permanent access to specific AI tools.
- Force-install and enroll every managed device automatically with zero-touch MDM provisioning via Group Policy (GPO), Microsoft Intune, Jamf, Kandji, and Google Workspace.
- Lock down enforcement permanently by pinning the extension at the system level so it cannot be disabled, removed, or bypassed, while simultaneously disabling native browser AI features and private browsing modes.
- Regulate AI prompt use on approved devices across organizations and educational institutions with real-time policy synchronization that keeps every console and endpoint compliant.
