Very soon someone will use it (or make a similar one) that routinely analyzes trends on news and social media, creates relevant new domain names then registers them and puts them on sale.
The website needs a FAQ page of some sort, for example if the links to register domains are affiliate links to Namecheap, maybe that should be disclosed somewhere.
One idea- you might want to add the option to restrict suggestions to certain TLDs. It suggested a bunch of .xyz, .cc, .guru etc stuff which I'm really not interested in.
Otherwise a cool tool!
