The Ten-Minute Free AI Check

See what the free AI your customers actually use says about your business, what sits under that answer, and which AI to pay for on your team.

01 Your customers ask the free one

When you check what AI says about a business, you probably check on the plan you pay for. Your customer probably doesn't.

According to a16z, the venture firm, only about 3% of Americans paid for ChatGPT in August 2026, from a panel of U.S. receipt and card data. Across ChatGPT, Gemini and Claude together, about 4.5%. (a16z invests in this market, so keep that in mind.)

The free version is a different product in two ways:

A different model. The paid plans, Plus and up, answer with GPT-6 Sol. Free answers with GPT-6 Luna, the smaller model in the family. The $8 Go plan runs Luna too. A box under the answer. Since February 2026, ChatGPT has shown ads to Free and Go users in the U.S., in a sponsored section under the answer. Plus and above don't see them.

OpenAI says ads don't influence ChatGPT's answers. Take that at face value. But as far as I can find, nobody has published whether the free model names different businesses than the paid one. That is why you check, on the version your customers use.

The ad doesn't change the answer. It changes what sits right under it.
02 The ten-minute check

Three checks, about ten minutes. Run it on your own business or a client's.

Use a free ChatGPT account, not your Plus. If yours is paid, sign up for a second one with another email.
Ask the plain questions your customers type. The three questions in the box below.
Ask the same questions in Google's AI Mode, Gemini and Claude. AI Mode is the AI answer inside Google Search. Gemini is Google's AI assistant. Claude is Anthropic's.
Screenshot two things every time. Who gets named, and whether there is a sponsored box under the answer.
Compare free with paid. Named on paid but missing on free? That is the gap that matters: free is where most of your customers are.
The three questions
Who is the best [BUSINESS TYPE] in [CITY]?
Is [YOUR BUSINESS NAME] any good?
What does [YOUR MAIN SERVICE] cost in [CITY]?

Example: a roofer in Columbus asks "Who is the best roofer in Columbus?" and "What does a new roof cost in Columbus?"

03 Log it once a month

Run the check once a month, so you notice when a sponsored box shows up. Since May 2026, any U.S. business can buy ChatGPT ads itself, with no minimum. Google is testing sponsored ads inside AI Mode's recommendation lists.

Monthly AI answer log

Question: [QUESTION, WORD FOR WORD]
App and account: [CHATGPT FREE / CHATGPT PAID / AI MODE / GEMINI / CLAUDE]
Were we named? [YES / NO]
Who else was named: [NAMES]
Sponsored box under the answer? [YES / NO, AND WHOSE AD]
Sources the answer cited: [LINKS]
04 Read what the answer is built from

One study of more than a hundred brands, by a company that sells this kind of tracking, found about 78% of the sources AI engines cited were the companies' own websites. So click the sources under each answer.

Watch for old pages. If the answer is built from an old directory listing or someone else's review page, that page describes you to most of your customers.

If the free answer is thin on you, the fix usually starts on your own site. Check that it says three things plainly:

Your prices. So "what does it cost" has an answer from you.
Where you work. The cities and areas you serve, written out.
Plain answers to the questions people actually ask. Start with the three questions above.
05 Which AI to pay for on your team

The same a16z report shows who pays. The top 1% of payers account for 19.5% of the consumer AI spending it could see, more than the bottom half combined. Those top payers spend about $903 a month on average. The typical payer spends $25.

Your team likely has the same shape: one or two heavy users, everyone else using AI a little, if at all. So don't buy everyone everything:

Fund the one or two properly. The higher tier, and the tools they actually ask for. Put everyone else on one business plan. For ChatGPT, that is ChatGPT Business.

Not because free is bad. On a free account, your team sees ads, and by default its chats can be used to train the models. OpenAI says it doesn't train on business plan data by default.

Our AI spend, on one line each
Heavy users to fund properly: [NAME], [NAME]
Tools they asked for: [TOOLS]
Everyone else: [NUMBER OF PEOPLE] on one business plan: [PLAN NAME]
