What a free AI visibility checker shows

Some ask AI engines about your brand and show what they said: HubSpot's grader is a one-time check of what the engines say from their training data[7], and Ahrefs' needs no sign-up[8]. Others check a page's readiness for AI search[9][4].

A single check is one answer per question, and AI answers change from one day to the next[10]. So a free check tells you where you stand today, not whether a change worked.

The table marks each tool whose own page offers a free audit, and each tool below quotes its words.

supereo's free audit

If you want to go on from there, supereo tracks those questions, does the work and proves each move against control questions.

Questions

What is the best free AI visibility checker?

The tools in the table each offer one, by their own pages: supereo's free audit, Profound's AEO Report[1], AthenaHQ's audit[2], Scrunch's brand audit[3], Writesonic's free tools[4], Otterly's GEO tools[5], Semrush's AI Visibility Checker[6], HubSpot's AI Search Grader[7] and Ahrefs' checker[8]. supereo's is our pick: it asks the questions your buyers ask and shows every answer word for word.

Is supereo's AI visibility checker free?

Yes, with no card. It asks the AI engines your buyers' questions and shows every answer: run it here.

Do free AI visibility checkers need a sign-up?

Some don't: Semrush's runs without an account[6], and Ahrefs' needs no sign-up[8]. HubSpot's grader shows its full results after a short form[11].

How often can I run a free AI visibility check?

Semrush's checker runs three times a day for free[6], and HubSpot calls its grader a one-time check[7]. To see a change over time you need the same questions asked again and again, which is what tracking does.

How we compiled this

Every price, prompt cap and AI engine on this page comes from each tool's own pricing page, and every capability from the tool's own product pages, docs and free tools. supereo reads them every week and keeps a value only when the page states it word for word; each tool on this page names the page and the day it was last checked.

Prices are US dollars a month on monthly billing, or the monthly price of an annual plan where that is the only price the page states, marked billed annually. A free trial is not a free plan, and custom pricing is a price the page does not publish. A tool sold only as part of a bigger product says so beside its prices.

Yes means the tool's own page says it, in the words quoted under each tool. A dash means none of the pages we read says it, so the tool may still do it without saying so there.

We make supereo, so it is listed first, as our pick. The other tools follow by how many of the four jobs their own pages claim, then by price.

Where this page's words state something the dataset doesn't hold, such as a change a tool made, the sentence links its source and the day it was read.

How supereo measures its own results, with every number it runs on: How supereo measures.

supereo (supereo.app) is an AI agent that does everything it takes to get your brand recommended by ChatGPT, Gemini, Perplexity, Claude and Google, on your site and off it: site fixes, new pages, roundups, placements and video. It proves what worked against control questions. Made by superagnt.
