Why switch
AI Chat Guard vs Chrome Safety Check
Chrome Safety Check warns after Google's scanners catch a malicious extension. AI Chat Guard runs scoped detection on five AI sites in real time so prompts cannot leak before Google's catch-up runs.
| Feature | AI Chat Guard | Chrome Safety Check |
|---|---|---|
| Monthly price | $2.99/mo | Free (with the trade-offs above) |
| Account required | No — install and use immediately | Often yes (varies by competitor) |
| Data leaves the browser | No — on-device by default | See competitor privacy policy |
| Ownership transfer risk | Aegis never sells extensions | Varies — see ExtensionWatch in this catalog |
| Bundled with Aegis Pro Pack | Yes — $9.99/mo unlocks every extension | No bundle |

Common questions
- Which AI sites does AI Chat Guard cover?
- ChatGPT, Claude, Gemini, DeepSeek, and Perplexity. The extension only runs on those five domains, so it never sees your banking or email pages.
- What does Safe Mode actually do?
- When enabled, Safe Mode disables every other extension only on the AI chat tab. Your password manager and tracker blocker stay active everywhere else; only the AI conversation runs in a clean browser context.
- How is this different from a general anti-malware extension?
- General anti-malware tools watch all sites and react after a known-bad extension is identified. AI Chat Guard is scoped to the five AI sites where prompt exfiltration is the highest-value attack and acts before classification.
- How does the Aegis Pro Pack unlock AI Chat Guard?
- Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.
- Where is my AI Chat Guard data stored?
- AI Chat Guard stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.
- Can I cancel AI Chat Guard Pro anytime?
- Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.
- Why should I trust an extension I just heard of?
- Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
