I’ve been using it for a year now and it is giving absolutely phenomenal search results right now.
For those that don’t know what it is, it’s a paid search engine - $54 per year for 300 searches a month. You get what you pay for, that’s for sure. They used to have a free tier, but I think you can still search for free a couple of times to try it out.
After using the trial for a month and reaching the limit, i decided to pay for the $108/yr unlimited searches.
Kagi did statistical analysis before assigning pricing (it was a long process that they would update us on while they gave us leniency on the quotas). They found that 300 per month was the sweet spot for a lot of regular people that might only search a few times a week or others that might only occasionally do deep dives.
edit: fixed an error, but also adding: no, i exclusively use kagi now on all my devices. give it a test run, it is dramatically different from ddg and googhell
