Frequently Asked Questions

Everything you need to know about AI Context Guard

Is my data truly safe with AI Context Guard?
Absolutely. 100% of the extension operates locally in your browser. We have no servers, collect zero data, and can't see your activity. Your sensitive information never leaves your device - it's technically impossible for us to access it.
Will this slow down my browser or AI platforms?
No. Our detection engine uses highly optimized pattern matching algorithms that complete in under 1 millisecond per scan. You won't notice any performance impact during normal usage.
Can I customize what gets detected?
Yes! Access the settings to toggle individual detection types, adjust sensitivity levels, whitelist specific patterns, and configure warning preferences. Full customization is available.
How accurate is the detection?
Our detection engine uses industry-standard regex patterns and validation algorithms with very high accuracy. False positives are rare and can be whitelisted. We continuously update patterns based on new threat intelligence.
Does this work on mobile devices?
Not yet. Mobile Chrome and Safari don't currently support extensions with the required capabilities. We're monitoring mobile browser extension APIs and will release mobile support when technically feasible.
Is AI Context Guard free?
Yes! The core extension is completely free and always will be. We may introduce optional premium features for enterprises in the future, but essential data protection will remain free forever.
Can I use this for my company or team?
Absolutely! AI Context Guard is enterprise-ready with GDPR compliance, audit logging, and team deployment capabilities. Contact us for enterprise support and custom deployment options.
What if I accidentally submit something anyway?
You can immediately undo the submission using Cmd+Z (Mac) or Ctrl+Z (Windows). AI platforms typically don't process content instantly, giving you time to retract. However, prevention is always better - that's why our warnings are designed to catch issues before submission.
