If you read the readme, this looks like it's specifically for when you don't know the correct tld or spelling of the site you're looking for. Google searches often censor sites of borderline legality, but they'll usually still have Wikipedia articles with accurate links.
This specifically only redirects .idk domains as a search helper. Could it possibly work better as a browser extension? Maybe. :)
I still use Ada daily for my personal projects after having used it at work. I find it compliments my thinking patterns well. My only gripe with it is that they ate too much of their own dog food at AdaCore and now it can be hard to install Ada and gprbuild (due to a circular dependency). Plus gprc stole libgpr and broke some stuff too.
