NeuralVoid is a one-click hosts-file blocker that cuts off telemetry from major AI-powered tools: GitHub Copilot, Grammarly, Adobe Creative Cloud (Photoshop/Firefly), Microsoft Windows/Edge Copilot, and more.

It adds precise domain blocks to your hosts file (with backup/restore) to stop the constant phoning-home of usage data, keystrokes, and context snippets to train their models. No background processes, no firewall rules—just surgical DNS blocking.
