About GEO Tool Index
GEO Tool Index records what AI visibility tools cost and what each plan includes. These are the tools that track whether ChatGPT, Gemini, Perplexity and Google's AI answers mention a brand. The index covers 43 tools.
What we publish
- A comparison table and a profile for every tool, with each plan's price, billing basis and limits.
- A price-change log, a free dataset (CSV and JSON, CC BY 4.0) and pricing statistics computed from it.
- A weekly email memo on what changed.
Where the data comes from
Every value is read from the vendor's own public pricing page and stored with its source URL and the date we checked it. Anything a vendor doesn't state is marked UNKNOWN rather than guessed. We re-render every pricing page each week and only log a change after confirming it on the live page. Full details are in the methodology.
How the site is funded
We sell featured listings ($149 a month) and newsletter sponsor slots ($99 an issue). Some outbound links are affiliate links. All of these are labelled. None of them changes the data, prices or the order of the data tables, and vendors can't write or edit what we publish.
