AI visibility tool price changes

How a change gets on this page

1. A script opens every vendor's pricing page each morning from a US server, keeps the lines about prices, plans, prompts and trials, and compares them with the day before.
2. When a number moves, we open the live page ourselves, save a dated screenshot and update the tool's data.
3. The change is added here with the date we confirmed it and, when we can find one, the last archived copy that still showed the old price. That's the "When" line: the change happened somewhere in that window.

Wording edits, reworded feature lists and design changes aren't logged. Neither are differences we only noticed against our own notes from before daily reads began, because we can't show what the page said then. Current prices for every tool are in the price index; how we read pages is on the method page.
