ShadowGuard watches your prompt the instant before you hit send, catches API keys, passwords, emails, IDs and more, and redacts them automatically — no reload, no manual cleanup, no copy-paste.
Free 7-day trial, fully functional. No account required to try it.
Everything happens locally, in the moment you're about to send — nothing is scanned in the cloud.
ShadowGuard sits quietly in the prompt box of ChatGPT, Claude, Gemini and other AI chatbots. No change to how you write.
The instant you hit Enter or Send, your draft is scanned locally against dozens of detectors.
Low-risk data gets swapped for a placeholder automatically. High-risk secrets stop the send entirely.
Secrets and government IDs are blocked outright. Everything else is redacted automatically, in place.
No backend, no account, no tracking. The whole point is that your data doesn't go anywhere new.
Detection happens on-device. Your prompts are never sent to any ShadowGuard server, because there isn't one.
Nothing about what you type or redact is collected, logged remotely, or sold. Ever.
Activating a license sends only the license key itself to Lemon Squeezy — nothing else. Full details.
No subscription for individual use. Pay once, keep it forever.
