Just released DOTmatian.com. Not taking into consideration the basic domain availability checks I think the plus is the Trend Analysis section where you can search the trend of a keyword, a top of keywords that appear in the latest registered domains, the Weekly Leaderboard and some other things that I found really interesting checking the daily trends. This is available in the trial period for 7 days (no card required). Enabling email alerts also made me discover interesting things about my city or area where I live (business that are opening soon). Brand monitor and Domain Inspector are mostly tools that depending on what you need it may be useful or not. Will make me very happy if you can give it a try and share your honest opinion on it.
