Kagi is a paid alternative to ad-supported search engines like Google and DuckDuckGo. It has recently revised its pricing model, reducing the cost for a plan with unmetered searches from $25 per month to $10.
Kagi boasts the following (and more) features:
- Blocking or boosting specific domains in your search results
- “Lenses”, which are individual setting profiles (e.g. region locks, domain whitelists) that can be applied to search queries
- All of the Bangs that DuckDuckGo has (e.g. type “!yt” in front of your query to immediately search on youtube.com)
- Universal Summarizer, which works with any website, PDF document, YouTube video and more
This blog post goes into full details about Kagi’s capabilities.
That’d be weird if they couldn’t, there’s no way they can improve their search engine other than by watching the way users use it.
Otherwise it exists in a vacuum.
I would guess they mean that they can’t see which queries belong to which users.
