Kagi Assistant

By KagiPalo Alto, United States1 product across 1 category

Strong fit. Sits on top of a search engine you pay for rather than one funded by advertising, so the results behind an answer are not ranked by who bought them.

Free plan: Yes; Trial tier, 100 searches with the Assistant included, no card needed
Month to month: $5/mo; Starter
Billed yearly: $4.50/mo; $54 a year, Starter plan −10%

Watch out: The free tier is a 100-search trial. Beyond that you are buying the search subscription, and the assistant comes with it rather than being sold on its own; prices exclude sales tax.

Free	$0	Trial tier, 100 searches with the Assistant included, no card needed
Starter	$5/mo · $4.50/mo yearly	300 searches a month and the Assistant in Quick mode
