Free AI Visibility AuditWe publish nothing without a source link, we do not republish other people's tables, and we say which of these entries a person checked.
Prices, context windows, release dates and deprecations are read from the provider's own catalogue, documentation or announcement, and every published entry links to it. We read other trackers to notice what we have missed, and that is all we do with them: a lead from one opens a task to go and check the provider, and our software refuses to publish it as anything else.
Model catalogues are re-read every three hours, provider pricing pages every six, and the cross-checks daily. Each source records when it last answered and whether it answered cleanly, and a source that has been failing shows as failing rather than as quiet.
When it happened, how precisely we know that, when we detected it, and when we last re-read the source and found it unchanged. They are kept apart on purpose: a re-check that finds nothing new updates the verification stamp and does not touch the page's modified date, because telling a search engine a page changed when it did not is a claim that gets discounted, and deserves to be.
A title reading "(September 2026)" means the page was verified in September 2026, not that it was generated then. If a page has not been successfully re-checked inside the current month, the month does not roll and the page says when it was last confirmed.
Only a price change read from a structured catalogue, and only when the move is within a plausible range. A change larger than fivefold, a move to or from free, a page whose content hash shifted, and anything written from a news feed all wait for a person. A hash tells us a page differs; it does not tell us what differs, and a footer year rolling over produces the same signal as a price cut.
A model page is created as soon as the model appears in a provider's catalogue. Whether it is offered to search engines is a separate decision, made on whether anybody searches the model's name. Pages that do not clear that bar stay useful, stay linked and carry noindex, because a folder full of pages nobody searches for makes the pages people do search for harder to find.
A wrong number is corrected on the page it is on, and the change is logged as its own entry with the date. Nothing is quietly edited: a tracker whose history can be rewritten is a tracker with no history.
Found something wrong? Tell us and we will check it against the source the same day.
The same discipline behind this tracker is what we use to audit whether AI answers cite you: named sources, dated evidence, and a number you can check.
