    Tool that helps you find domains for your idea▲5

    I built a simple tool that suggests good domain names based on your idea, something I usually spend way too long on myself. It's free, no sign-up needed, 5 searches / day (a bit wonky, working on that part). Mainly built it for myself but would love some feedback and tips for improvement! :) Thanks!
