Where the facts come from
Every plan, price, and feature on this site comes from the vendor's own pricing page or documentation, opened on the date shown at the top of each page. Company history comes from the companies' own announcements, regulatory filings, news coverage, and, for basic facts like founding dates, Wikipedia, and each source is named at the bottom of the page that uses it. All the sources are also on one page.
Prices change
AI plans change all the time: tiers get renamed, limits move, and prices go up and down. Every price here is the US list price before tax on the date the page was checked, not what I pay after any discount, and I'll update it when the vendor does. Check the vendor's own page before you buy anything.
What this site doesn't cover
It lists the tools and says, in a sentence, what I use each one for. It doesn't describe how I work with them in detail, and it isn't a review or a ranking.
Money
Nobody paid to be on this list. There are no ads, no sponsors, and no affiliate or referral links, and every sign-up link goes to the vendor's own page.
