This is awesome. I usually do the same thing, only manually. That's how I came up with some of my favorite domains. I also accidentally stumbled upon blackmail.io doing this. At that moment I wasn't looking for single words, and infact was thinking of "black" and "mail". Lucky run, I guess.
Thank you! I've found myself doing it manually too, which is where the drive for this came from. I think I would use it even if someone else had made it, if that makes sense
