AI pricing & free tier tracker
Free tiers and the cheapest paid plan for 9 tools we list, taken from each vendor's own pricing page. Last checked Oct 28, 2026. 7 of 9 prices were confirmed on the official page at the last check.
Prices are in US dollars as shown to a US visitor, before tax. Vendors change plans often, so always confirm on the official page before you buy. Where a page blocks automated checks or loads prices with JavaScript, we show Check site instead of guessing.
