Anyway, at $10/mo I’m not quite prepared to put my money where my mouth is. $5/mo would be much more attractive, and I would guess they'd have better profit at that price. How much does each user cost them?
Edit: Thanks everyone for the pricing info! I guess in a world where we expect search engines to be free, we don't realize how expensive they actually are to run (at least at smaller scales like Kagi).
Intuitively I would have expected the expensive part to be building the index and for each query to cost fractions of a cent. I am extremely surprised to learn that each query apparently costs them $0.125.
