I signed up for the $10 plan, before they introduced unlimited searches. One month I went over and thought ok, I'm not really ok with making more than 10. A few weeks later they switched to unlimited.
The lens feature is great. I have one for searching my company's public documentation etc.
The redirect thing is great too, it can rewrite URLs on the fly, e.g. Reddit -> old.reddit.
I have used other search engines in the past, like ddg for a long period, and others. I always ended up just doing !g on every search.
Kagi is the first where I don't notice I'm using another search engine and actually if I'm on Google I notice my experience is worse!
Great to see updates like this, in the months I've been using it it has improved so much already.
