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