NoeticGuard Shield

On-device PII and brand-term masking for AI chat sites — before prompts leave the browser.

NoeticGuard Shield is an on-device AI egress firewall for the browser. What it does • Masks emails, phones, cards, national IDs, and other policy-enabled PII before prompts leave supported AI chat websites — in any language (Turkish, English, or mixed). • Optional Brand Guard dictionaries redact competitor names and restricted terms (synced from your NoeticGuard workspace). • Media Guard (Startup+ workspaces) can block image/file uploads and image paste on supported sites. • Deterministic tokens stay local so your team can unmask in context when needed. What it does not do • It does not send raw prompts to NoeticGuard for cloud masking. • It does not replace your LLM provider — it protects data before egress. Getting started 1. Create a workspace at https://app.noeticguard.com 2. Create a publishable key (ng_pub_…) under API Keys 3. Open the extension popup → paste the key → confirm connected 4. Visit a supported AI chat site and send a test prompt with a fake email Privacy: https://noeticguard.com/privacy Docs: https://noeticguard.com/docs/browser-shield Support: support@noeticguard.com
