How we record changes
A machine retrieves the pricing pages of the tracked vendors every day. A change only appears here once the new price holds for several measurement days — one-off mis-measurements never show up. We measure the cheapest regularly bookable paid tier.
The full history per tool is in the AI tool price index, the current state of all tools in the AI Tool Monitor. The raw data is available as open data for download.
