The best I can say is that it technically does the job, just slowly and not particularly well. There really isn't anything which even approaches the search quality and featureset of Kagi. I don't even have the strongest opinion on working with Brave even though they're clearly awful given how monstrous both Google and Microsoft are (who are both part of the core foundation of their search), but their approach to this whole situation leaves a bad taste in my mouth. I turned off auto-renewal of my subscription but I really hope they take a step back and realize how much goodwill they're destroying for a significant part of their userbase so I can resubscribe. There's no suitable replacement.
That's fine, just let the rest of us do the same.
