Asking price next to our estimate, so you can judge the deal at a glance.
How the estimate works
Read the name
Length, real English words, hyphens and digits, and how well it works as a product or AI tool name.
Check every extension
Whether the same name is registered in 268 extensions, from .com and .ai to .io and .de, and whether the key ones are active, parked or for sale.
Anchor to real sales
Calibrated against comparable .si deals, plus a private database of .ai and .com sales of similar names.
Show the confidence
A range, not just one number. It's wider when there are fewer comparable sales.
