The AI Software Index 2026
What ChatGPT and Gemini actually recommend when a buyer asks for software — measured, not guessed.
What we did
- ·We wrote ~80 questions per software category — the way real buyers ask them. Things like "What's the best CRM for a small business?" or "I'm a freelancer and need invoicing software."
- ·We asked them on the real ChatGPT and Gemini apps — the same thing a buyer sees, not a developer API.
- ·For every answer we recorded which brands were named, which one was recommended first, and which websites the AI cited as sources.
What we found
Seven things the data says, in plain English.
- 1ChatGPT and Gemini disagree a lot. In 1 out of 3 categories, they name a different #1 product. Which AI your buyer uses changes who gets recommended.
- 2ChatGPT links to the winner's own website. Gemini doesn't. When ChatGPT recommends a product, it cites that product's own site 53% of the time. Gemini: only 13%. Gemini relies on third-party pages instead.
- 3Gemini trusts small blogs, not big media. Its most-cited "independent" sources are blog posts written by other software companies — often about categories they have nothing to do with.
- 4Review sites barely matter. G2, Capterra, and TrustRadius together get only 5% of all citations.
- 5The answer changes when you rephrase the question. In some categories one brand always wins. In others, asking the same thing in different words gives you a different "best" tool almost every time.
- 6Saying who you are changes the answer. "I'm a freelancer" and "we're an enterprise" get different recommendations — in some categories a brand jumps from winning 34% of answers to 90%.
- 7US and UK buyers get different winners. The #1 recommendation flips between US- and UK-phrased questions in about half of the categories we could measure.
The most AI-visible software brands
How many category leaderboards each brand appears on, and how many categories it actually wins.
Being everywhere and winning are different things. Salesforce shows up on 13 leaderboards and wins none of them. QuickBooks shows up on 7 and wins 5.
Locked up vs. up for grabs
In some categories one brand wins no matter how you ask. In others, the winner changes with the wording.
