Something I love about Kagi that isn't often known, is they will pro-rate based on days. If you are on an existing plan, you can upgrade to Ultimate, try it out for a few days, and then downgrade and only pay for the days you used it. I despise the subscription model generally, but if we're going to have it then I wish more companies would do pro-rating! Anyway, you can try it out for very low risk.
