I'd never pay for, let alone use, a search engine* that has an official Discord group.

* Kagi seems to just scrape and provide a mix of other search engine's results, meaning it's really just a metasearch engine.

They also have their own index. But in any case, what matters here is the product UX itself not the internal details, and they do offer a classic search experience

Unfortunately some hip folks got it in their head that the correct way to provide support is discord.
