Lazarai builds privacy tools that run on your own device. Our first, GHOSTWALL_x, stops programs on your PC from quietly sending your data to AI services. No cloud, no accounts, no telemetry.
From Lazarus, the one called back from the dark. Software that brings your data back under your control, and keeps it there.
A Windows tray app that stops programs on your PC from quietly sending data to AI services. It works inside Windows itself, through the Windows Filtering Platform, and everything it does stays on your device.
Turn each AI service on or off from the tray: OpenAI, Anthropic, Google Gemini, Microsoft Copilot and Perplexity. Optional "Also block browsers" mode covers your browsers and extensions too.

GHOSTWALL_x uses the Windows Filtering Platform to refuse new outgoing connections from the apps on your PC to the services you've blocked. Everything else keeps working normally.

No cloud, no account, no telemetry. Block rules are temporary and disappear when the app quits, so a bug can't leave your PC stuck. Turn on "Start with Windows" and it comes back at login.

More and more of the software on your computer talks to AI services in the background, and it rarely asks first. Once your data leaves your machine, it's out of your hands.
Lazarai exists to give that control back. GHOSTWALL_x is the first tool. More are coming, all built on one rule: what's yours stays yours.
