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.
📋 RDAP Verification
For enhanced accuracy, we also perform RDAP (Registration Data Access Protocol) queries to cross-verify domain registration status. RDAP provides authoritative data directly from domain registries, offering more reliable information about registration dates, status, and availability.
💡 Tip: Always verify availability with your preferred registrar before making purchase decisions
