I remember being so disappointed with the Brave Search. They had a great opportunity to deliver something really amazing, and gain an instant following due to its integration with their browser. What they delivered was so mediocre and unimpressive. I had been using SearXNG for the past year or so, and I like it because of how it brings so many different data sources into a single interference, but it was lacking intelligence, so you really needed to know what you were looking for, and how to best access it using bang commands. Kagi does it all, and its integrated intelligence makes it simple to use.
