How It Works
🤖 AI-Powered Generation
Our system uses advanced AI algorithms to intelligently generate 4-letter domain combinations. Rather than simple random generation, the AI considers letter frequency, pronounceability, and patterns to create more memorable and brandable domain names.
🔍 DNS Lookup Verification
Each generated domain is checked in real-time using DNS lookups to determine availability. While DNS checks are highly accurate (～90-95%), final registration availability may vary due to registry locks, premium domains, or recent registrations not yet propagated.
💡 Tip: Always verify availability with your preferred registrar before making purchase decisions
