I don't want to have to pause before I search and think "do I need to search for this? should I look through my bookmarks, notes, etc? is this worth one of the 7 searches my $5 plan will cover for the day?".
I've been a frequent user of Kagi for the past ~9 months. Last month I made 1600 searches.
I've even 'tipped the difference' (~$70) in the past to support Kagi. It feels gross that they're now upcharging me despite the goodwill I showed them. I know they're a business, but if you're a business, and you're not willing to respect your users, then don't ask for donations.
I hope that something better than Google comes along. It was Kagi, but now it's back to the drawing board for me.
My advice to Kagi: make searches cheaper. This product has no future otherwise.
