How this index is built
Every field came off the vendor's own page, and the page it came from is linked next to it with the date it was read.
What gets recorded
For each entry: the price the vendor publishes, the plan name attached to it, the engines the vendor says it tracks, whether free access exists, and the URL and date those were read. Where a vendor publishes nothing, the entry says "not published" instead of guessing.
What is never recorded
No invented ratings. No star scores. No editor's picks. No affiliate links and no paid placement, so ordering cannot be bought.
Sorting is mechanical: cheapest published entry price first, then free-to-start, then vendors publishing no price, then anything no longer operating. Ties break alphabetically.
Inclusion rules
| Heading | An entry lands here when | Count |
|---|---|---|
| Dedicated AI visibility tools | The product is sold on its own, and AI answer tracking is the whole product. | 71 |
| SEO suites with AI search tracking | AI tracking ships as a module inside a platform that sold something else first. | 24 |
| Free AI visibility checkers | The whole product runs free with no paid tier behind it. | 1 |
| AI visibility tools you can use free | The vendor publishes a free tier or a free one-off audit. Time-limited trials do not count. | 35 |
| AI visibility tools under $100 a month | Published entry plan is above 0 and below 100 per month in the currency the vendor itself publishes. Figures are not converted between currencies, because a converted price matches no source page. | 31 |
| Enterprise AI visibility platforms | No pricing is published anywhere on the vendor's own site. | 52 |
Why closed tools stay listed
Several widely shared roundups still recommend products whose domains are now parked for sale. Those entries stay here, marked, with the date the domain was checked. An index that quietly drops them teaches you nothing about how fast this category turns over.
Built for machine reading
Every page has a markdown twin at the same path plus index.md, a JSON representation, and a linked OpenAPI description. Agents are a first-class audience here, not an afterthought, and quoting is free with attribution. Start at /agents.md.
Corrections
Vendors change prices without notice. If an entry is out of date, send the correction with the URL that shows it and the entry gets re-read.
