What did we actually test?
Adacity ran 20 real buying questions through three AI assistants, ChatGPT, Gemini, and Claude, which gave us 60 answers to read side by side. The questions covered the places digital-first buyers actually start: e-commerce products, SaaS tools, and a few local services for contrast. They were the kind buyers actually type, like "best standing desk for a home office?" or "top project management tool for a small team?"
We weren't grading the writing. We were tracking one thing: when a buyer asks an assistant for the best option, which businesses get named.
The short version
Search used to hand you ten blue links and let you decide. AI hands back a finished shortlist, and most of the time the three big assistants agree on it.
- Ask any assistant for the best option in a category and you get 3 to 5 brand names, not a page of results. There is no page two.
- The same names win across ChatGPT, Gemini, and Claude. In settled categories the overlap is near-total, so the shortlist barely moves.
- You don't earn that slot on your own website. About 85% of AI brand mentions trace back to third-party sources, so the businesses AI names are the ones other sites already talk about.
What does AI say when someone asks for a recommendation?
It names a short list and stops. Ask for the best standing desk or the best project tool, and the answer is 3 to 5 brands, each presented as a settled choice with nothing behind it to scroll past.
A buyer used to compare a page of options and pick one. Now an assistant compares for them and returns the finalists. You are either on that list, or the customer never learns you exist.
Do the three assistants agree?
The three agree more than you'd expect, and the agreement gets tighter the more established the category. In our test, project management drew the tightest agreement of all: Asana, Trello, Monday, and Notion came back from all three assistants, every time. Four names, no daylight.
The pattern repeats across digital-first categories. Standing desks converged on FlexiSpot and Uplift. DTC mattresses converged on Helix and Brooklyn Bedding. Sustainable clothing kept returning Everlane, Pact, and Kotn. Different products, same dynamic: a small, stable set of brands that every assistant has already decided to trust.
That cuts both ways. If you are one of those names, you are compounding a lead that is hard to claw back. If you are not, you are watching competitors get recommended in rooms you can't see into.
Where does AI learn who to name?
Mostly from other places on the web, not from your own site. Research on how AI picks brands finds that about 85% of AI brand mentions come from third-party sources, not a brand's own website. Editorial reviews, comparison articles, and community threads are what teach an assistant who belongs on the shortlist.
The old search playbook doesn't transfer cleanly, either. In Google's AI Overviews, only 38% of citations now come from pages that rank in the organic top 10, down from 76% a year earlier, according to Ahrefs. Ranking first is no longer the same as getting cited. Your AI visibility and your search rank have quietly come apart, which is why a strong SEO position can sit right next to an empty AI shortlist.
Which categories are still wide open?
The ones where the three assistants haven't settled on a winner yet. Categories the three already agree on, like project management, are hard to crack without years of community presence. The opening is in the newer and more specific corners: a vertical SaaS niche, an emerging DTC subcategory, a product so new the assistants are still guessing. Form builders show the milder version: Typeform and Jotform appear across the board, but newer names like Tally are still breaking in.
In those categories AI often names one business, or none. The first brand to show up consistently across all three assistants tends to own that slot, because each citation it earns makes the next one more likely. Most owners haven't claimed their category. Yet.
Why does this matter for your business?
Because AI is now where a growing share of buyers start, and that traffic is unusually good. AI-referred visitors convert at 6 to 25 times the rate of traditional search visitors, according to Vercel, Webflow, and Go Fish Digital. A small channel that converts that well can outweigh a much larger one that doesn't.
So the cost of being left off the shortlist isn't a slow decline. It's binary. If an assistant doesn't name you, those buyers never reach your site, compare your product, or see your pricing. The opportunity is to get named where the decision is actually being made.
