I think they realized their price structure was confusing/annoying towards the end of last year. Now it’s just $5/mo for 300 searches or $10/mo for unlimited. (There’s also still an expensive $25/mo plan for early access to some of their LLM experiments apparently?) You got me curious and I couldn’t find any mention of per-search overage billing. This feature request thread from 2022 just makes it sound like Kagi search gets shut off.

I bouncing hard off of Kagi when they had the original pricing structure you described. Bringing back aughts era SMS overages or just mentally having to count searches doesn’t exactly found like a fun time. I’m going to give the $5 plan a try this month to see how far that gets me. $10/mo is still a tough sell for Internet search. If I really find it substantially better, I might convince my spouse into trying the two seat $14/mo unlimited “Duo” plan for a while.
