Checked by a human
The 1 to 2 working days is deliberate: an instant automated score can only tell you what a robot noticed. Yours comes with an expert’s read on what matters and what to do first, and nobody follows it with an automated drip sequence. One report, from one person.
The honest bit
What the free check cannot tell you
They are directionally useful but not repeatable: when we re-ran the same buyer prompts through the same engines on three separate days, the brands named changed in 83% of prompt-and-engine combinations, which is why a free check tells you whether you have a problem, not how big it is.
- It is one sample at one moment. AI answers are generated fresh each time, so the same question can return a different shortlist an hour later.
- It does not show a trend line. One snapshot cannot tell you whether your visibility is rising or falling; only repeated scans of the same prompts can.
- It does not tell you what real users saw. We ask the engines through their APIs and search surfaces, which can differ from what a logged-in consumer gets in an app.
- It cannot measure every question your buyers ask. The free check samples a handful of buyer prompts; the full panel on paid tiers starts at 25 and can grow to 40.
We measured the wobble
We re-ran the same 41 UK buyer prompts on our own site through 5 AI engines on three consecutive days (18 to 20 August 2026). The brands named changed in 81% of prompt-and-engine combinations, and in 7% whether we were mentioned at all flipped between days. Across the three UK sites we monitor (482 combinations, all six engines), the figures were 83% and 14%.
Method: we took every prompt-and-engine combination with a scored answer on each of three separate days, compared the brands each answer named, and counted a combination as changed if any day's list differed. Measured from the AEOscore scan database on 20 August 2026.
“Ask an engine the same buyer question on Monday and again on Wednesday and you will often get a different shortlist. The variance comes from the engines themselves: generated answers genuinely differ run to run. A free check tells you whether you have a problem, not the exact size of it.”

Direct answers
Free check questions, answered in one sentence
Is there a free tool to check if ChatGPT and Perplexity mention my brand?
Yes: AEOscore runs a free UK AI visibility check across ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews and AI Mode, with no card and no account, and emails a human-checked score out of 100 within 1 to 2 working days.
Are free AI visibility checkers accurate?
They are directionally useful but not repeatable: when we re-ran the same buyer prompts through the same engines on three separate days, the brands named changed in 83% of prompt-and-engine combinations, which is why a free check tells you whether you have a problem, not how big it is.
What is the difference between a free check and paid AI visibility monitoring?
A free check is one snapshot; paid monitoring re-runs the same buyer prompts on a schedule so you can see movement, and AEOscore's Monitor tier does this weekly at £99 a month, daily on the £1,495 Monitor + Strategist tier.
Do I need to give a card or sign up to use AEOscore's free check?
No: you give a domain and an email address, and one person emails one report back, with no card, no account and no automated drip sequence.
What does an AI visibility score out of 100 mean?
It is the share of your tested buyer prompts where an engine mentioned you, weighted so small samples cannot masquerade as certainty and tracked alongside how prominently you appear, so it is comparable to your own past scores and to a named rival, not an absolute industry benchmark.
Can a free tool tell me how to fix the gaps?
Most cannot: they report absence without a remedy, whereas AEOscore's free report includes one concrete fix to start with, and the paid tiers have in-house technical people who make the fixes rather than emailing you a to-do list.
