Every fact that changed, and why.
AI tools change their prices, free plans, names and data settings all the time, and AI rules move on a schedule. When a fact we track moves, it goes in the Ledger: what it was, what it is now, why it changed, and which lessons updated with it.

No changes recorded
237 facts are tracked, and every one still matches what we last recorded. When one moves, it appears here with the value it replaced and why. Open the Tool Atlas →
An email when a fact you rely on moves
Pick the tools you use and the rules you follow. You’ll hear from us when one of their facts changes, and not otherwise. No round-up, no newsletter, nothing to unsubscribe from twice. Free, and no account needed.
There’s an RSS feed too, if you’d rather it landed in a reader.
A ledger is a harder promise than a date stamp
Anyone can put “updated September 2026” at the top of a page. It costs nothing and proves nothing. The date can change without the content changing, and you’d never know. A ledger can’t be faked like that, because it has to show the value it replaced. If nothing moved, this page says so.
Every price, plan limit and date in every lesson is pulled from these facts, not typed into the text. So when one changes, the lessons citing it change at the same moment, and the count beside each entry is the real number of pages that moved, not a guess.
