FAQ

What is a TLD?

TLD stands for 'Top-Level Domain', which is the final part of a website address, like .com, .org, or .net.

Does the AI check if the name is already trademarked?

The AI checks domain availability but does not check if the name is already trademarked. It's important to perform this check separately.
