How the free score is built
A free AI visibility tool earns its points on what the free part shows and what follows it. Thirty points go to something free with no end date. A trial that takes a card scores 0.
| Criterion | Weight | How the points are given |
|---|---|---|
| Free with no end date | 30 | A free check or a free tier with no end date, 30. A trial that asks for no card, 12. Any other trial, 8. A trial that asks for a card, or nothing free, 0 |
| What the free part shows | 20 | The product itself, on your own brand, 20. A check on questions picked for you, 12. Scores or a preview from a name or a form, 8. Nothing free, 0 |
| AI engines asked free, with no end date | 15 | All six AI engines, 15. Two to five, or a number its page does not state, 10. One, 5. None, because the free part is a trial or there is none, 0 |
| The first paid step, a pack or a month | 20 | Under 10, 20. 10 to 49, 15. 50 to 99, 10. 100 to 249, 5. 250 or more, 2 |
| What the paid step commits you to | 15 | Credits bought once, with no monthly plan, 15. A monthly plan, 5. Priced only after a call, 0 |
The AI engines column counts only what stays free, so a trial scores 0 there whatever its plan covers. The first paid step reads the cheapest tier with a price on the tool's own page, in the currency printed there.
Free check, free tier or free trial: what each free AI visibility tool gives
Three things get called free: a check run once, a standing free tier and a trial. Of the fifteen other tools here, four give a check run once, two keep a small tier free, six offer the paid plan as a trial, and three give nothing without a card.
| What is free | What it gives | Tools scored here |
|---|---|---|
| A check run once | One run, with no end date to use it by | MentionChecker, Ahrefs Brand Radar, HubSpot AEO, AskWatch and Profound |
| A standing free tier | A small allowance that stays free | Promptwatch and AthenaHQ |
| A trial | The paid plan for a few days | Otterly, Writesonic, Peec AI, Superlines, Searchable and Gauge |
| Nothing free | A trial that takes a card, or no trial at all | Rankscale, Semrush and Scrunch AI |
A trial starts at signup, and when it ends the account stops tracking unless a plan is paid for.
What is AI visibility, and what does a free AI visibility check measure?
AI visibility is how often AI engines mention your brand when people ask about what you do. A free AI visibility check puts those questions to ChatGPT and Gemini and counts the answers that mention you. It is counted per question and per AI engine, so a brand can be mentioned on Gemini and missing on ChatGPT for the same question. A mention is your brand's name appearing in an AI engine's answer, whether or not a link comes with it.
What should a free AI visibility checker show?
A free AI visibility checker should show the answers about your own brand, who is mentioned in your place and which websites are cited. A score from a form, or a preview built from a brand name, does not show the answers themselves.
The questions people type about what you do are drafted from your website, you change any of them, and the check asks them on ChatGPT and Gemini, so you can check your brand in ChatGPT and Gemini without an account.
The report opens on three numbers. Mentioned is the share of answers with your brand in them, share of voice is your mentions against every mention in the check, and average rank is your place in the answers that listed names in order.
The standings rank every brand the answers mentioned, your own row marked, so competitor mentions you had never heard of show up beside the ones you know. A citation is a website the answer gives as its source, and the free report lists every one.

After the free check, a MentionChecker pack is $9, bought once, where every other tool here moves you onto a monthly plan. One question on one AI engine is one credit, and credits last 12 months.
| Credits | What that runs, for example | Price |
|---|---|---|
| 50 credits | eight questions on all six AI engines, once | $9 |
| 100 credits | 25 questions on four AI engines, once | $17 |
| 250 credits | 25 questions on five AI engines, twice, with what moved between them | $25 |

Every pack is on the pricing page, and the pay as you go AI visibility tracker page explains the balance.
What to do after the check
After a free AI visibility check, start with the websites the answers cited, which the report lists most-cited first. A cited page that leaves your brand out is the place to be mentioned. Then run the same check again from a pack, and the report shows what moved since the last run.
Why most tools are not ranked here
A free AI visibility tool is ranked here when its own pages publish its whole plan list and its free offer, which is true of sixteen of the 257 tools in the directory of AI visibility tools.
The other 241 are listed in the directory with what each one does.
Which one to pick

Questions people ask about free AI visibility tools
What is the best free AI visibility checker?
MentionChecker, at 95 of 100 in MentionChecker's ranking of sixteen free AI visibility tools, and no tool scored higher on any criterion. The first check is free with no card and no end date, and it runs on your own website with questions you can edit and every answer in full. After it a pack is $9, bought once, so the next check costs no monthly plan either.
Is there a free AI visibility tool?
Yes. Your first MentionChecker check is free, with no card: 5 questions about what you do on ChatGPT and Gemini, asked once, and the report keeps every answer. It has no end date, so it can be run whenever you are ready. After it a pack is $9, bought once, with credits that last 12 months.
How can I check my AI visibility for free?
Run a free MentionChecker check. Enter your website, and the questions people ask about what you do are drafted from it for you to edit. The check asks them on ChatGPT and Gemini, and the report opens when the answers are in. No card is asked for, and nothing is charged until you buy a pack, from $9, bought once.
Do free AI visibility tools need a credit card?
Some do. A trial that asks for a card turns into a paid plan unless it is cancelled, which is why this ranking scores it as nothing free. The free MentionChecker check asks for no card at all, and nothing is charged until you buy a pack, from $9, bought once, with credits that last 12 months.
Do AI visibility tools have a free trial?
Some do, but a trial is the paid plan for a few days, and then it is charged, while a free check or a free tier has no end date. Of the tools in this ranking, six have a trial as their only free way in, and only two of those ask for no card. A free MentionChecker check has no end date.
Which AI engines does a free AI visibility check ask?
The free MentionChecker check asks ChatGPT and Gemini, and a paid check can ask any of the six: ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Microsoft Copilot. No tool in this ranking gives all six free with no end date. One question on one AI engine is one credit once you buy a pack.
Is there a free ChatGPT visibility checker?
Yes. The free MentionChecker check asks ChatGPT and Gemini 5 questions about what you do, drafted from your website and editable, with no card and no end date. The report shows every ChatGPT answer in full, whether your brand is mentioned, who is mentioned in your place and which websites ChatGPT cited. After it a pack from $9, bought once, can ask all six AI engines.
Is there a free Gemini visibility checker?
Yes. The free MentionChecker check asks Gemini and ChatGPT 5 questions about what you do, with no card and no end date, and the report shows each Gemini answer in full with the brands it mentions and the websites it cites. A pack from $9, bought once, adds Google AI Overviews, Google AI Mode, Perplexity and Microsoft Copilot.
Are free AI visibility checkers accurate?
A free check is a first reading. 5 questions on two AI engines show whether your brand is mentioned at all, and answers change from run to run. A paid MentionChecker check with 25 questions on all six AI engines gives a steadier number, and running it again shows what moved.
Can a free AI visibility tool track competitors?
Yes. The free MentionChecker check lists every brand the answers mentioned in its standings, with your own row marked, without you naming any competitor first, so ones you had not thought of appear too. Each name opens the answers it came from. To watch them move, run the same check again from a pack, or set a repeat, which runs it daily, weekly or monthly from your balance.
How much does an AI visibility tool cost?
A MentionChecker pack from $9 for 50 credits, bought once, and one question on one AI engine is one credit. Credits last 12 months, so a month with no check costs nothing. A repeat runs the same check daily, weekly or monthly, each run paid from the balance, with no monthly plan.
How often should I check my AI visibility?
After the free check, run it again whenever something you control changes, such as a new page, a launch or news about you, or set a MentionChecker repeat daily, weekly or monthly. Each run is paid from the balance at one credit per question per AI engine, and the report shows what moved since the last run, so a quiet month costs nothing.
