Namefruits is a kind of intelligent Naming AI for business names. It is not only about quick name suggestions but creating a perfect and unique brand name or business name. Namefruits works in the background to build up an individual profile for every user and every project that is to be named. If you search a name for a software or app, Namefruits considers not only available domains but also checks app stores for example. If you start your own business, the tool also checks trademarks or business registers and other aspects. I don't know any other similar comprehensive solution.
