AI Visibility Index · November 2026

Asked about invoicing software in Poland, ChatGPT, Claude and Gemini named Fakturownia most often, in 100% of answers (its AI Recommendation Rate), then wFirma (92%) and iFirma (89%). Across 36 answers they named 16 different businesses, 7 of them only once. Each of four buyer questions was asked three times, in Polish, in November 2026.

The AI Recommendation Rate is the fraction of the 36 answers that named a business. The range under it is a 95% confidence interval: where two ranges overlap, the gap between those businesses could be chance.

Names are printed as the assistants wrote them. We have not checked that any of them is good, open, or real.

Questions about invoicing software in Poland

How AI assistants recommend invoicing software

ChatGPT, Claude and Gemini named Fakturownia most often, in 100% of 36 answers, then wFirma (92%) and iFirma (89%). The names come from what the assistants answered to four buyer questions in November 2026; we have not checked that any of them is good, open or real.

On the first name, yes: each of them named Fakturownia most often. 6 of the 9 listed businesses were named by two or more of them.

Each question was asked three times. Of the names an assistant gave for a question, 80% came back in two or more of those runs; the rest came up once. The 95% range beside each rate in the ranking shows how far it could move by chance.

Run the free checker: it asks ChatGPT, Claude, Gemini and Grok two of the Index questions for invoicing software, with the category and the place already filled in, and shows every answer word for word. About 30 seconds, no sign-up. The page on how AI assistants recommend invoicing software shows what an owner can work on. Nothing can guarantee that an assistant names you.

How to read this page

The full method

What it measures: Which names these models produce when asked cold, from what they learned in training. It is not a review, a rating or our recommendation, and a business missing here may simply be one the models were never shown.
Why the ranges matter: 36 answers is a sample. Asked again next month, most shares will move by a few points; the ranges say how far they could move by chance alone.
One business, several spellings: Branches, legal suffixes and spellings of one business are merged, and the other spellings are printed under its name. Names that might be two businesses are kept apart.
A name is wrong: If a business here is closed, misnamed or yours and you want it removed, tell us. We correct or remove it when the page is next published.
