Free AI Visibility Tool & Checker

What the free AI visibility checker does

Enter your brand name and your website. The AI visibility checker reads your homepage and writes 3 questions a buyer would type when looking for what you sell, without your brand name in them. It asks ChatGPT and Google AI Overviews each one, then reads every answer for your name, its tone and its links. You can replace those prompts with your own, written the same way.

Why no brand name in the prompts: an engine asked "is Acme any good?" names Acme because you told it to. The question that matters is whether it names you when a buyer asks about the category.

It runs the same scoring code as the paid audit, on the platforms the Free plan covers. You see your score and each platform's result straight away, with no account. The full report (every answer centred on the sentence that names you, the score for each prompt, the first fixes and the export) opens on an email address. The check waits a fixed time for each platform, so one slow engine cannot hold up your result.

How to read your result

The score

The 0-100 score uses the paid audit's formula: a weighted average of Mention Rate (40%), Accuracy (30%), Sentiment (15%) and Citation Rate (15%), multiplied by 0.2 + 0.8 × coverage, where coverage is the market-weighted share of the platforms in your audit that mentioned you at least once. Named on no platform, it is 0. Read it as a first look at a handful of prompts, not as your standing across AI search.

Accuracy reads 100

The free check has none of your facts, so it cannot tell a right answer from a wrong one. Accuracy counts at its default of 100, which lifts the score. A full audit compares every answer with the facts in your brand profile.

Each platform's state

Every platform shows one of four states: it named you, it answered without naming you, Google showed no AI Overview for your prompts, or there was no answer this time. Only the first two count toward the score. A failed call or a missing overview is left out, never scored as a miss.

The excerpt

Each answer shows an excerpt centred on the first place your brand is named, so you read the sentence that mentions you rather than the opening of the answer.

Citations and sentiment

Citations count the links in each answer and how many of them point to your site. Sentiment is read from the whole answer and from the words around your brand name, which count double.

What the free check does not measure

• Accuracy. No brand facts, so no wrong-price or wrong-date flags.
• Google AI Mode, Gemini, Perplexity and Claude. Those platforms are on paid plans.
• Your site's access. It does not read your robots.txt or test whether your firewall lets AI crawlers in. The free AI Crawler Checker does, and so does a free account.
• Competitors. Nobody else is counted.
• Change over time. One check is one snapshot, and nothing is saved for you to compare against.
• Location. No country is set, and Google AI Overviews is read from US English results.

Why one check is not a verdict

AI answers vary. The same prompt can get a different answer tomorrow, and vendors update their models on their own schedule. Treat one check as a first look, and judge what is broken over several audits.

How it compares with other free AI visibility checkers

Ahrefs, HubSpot and Adobe each offer a free AI brand visibility check, and each measures something different. A score from one tool does not compare with a score from another. We read each vendor's own page on 17 October 2026.

Pick the one that answers your question. To see whether AI names you for the questions your buyers ask, use a check that asks the category, not your name. To count mentions across a vendor's prompt set, Ahrefs covers more platforms than this free check. To see whether one page's text reaches AI agents at all, Adobe's extension reads it; our free AI Crawler Checker reads your robots.txt and requests the page as each AI crawler.

What a full audit adds

• More prompts, more often. Free: 5 prompts and 1 audit a month; Starter ($49/mo): 25 prompts and 15 audits a month; Growth ($99/mo): 50 prompts and 50 audits a month; Pro ($249/mo): 100 prompts and 150 audits a month.
• All 6 platforms on paid plans, Google AI Mode, Gemini, Perplexity and Claude included.
• Accuracy checks against the facts you enter: prices, founding year, location and features. The detail of each flag starts on Starter ($49/mo).
• The AI crawler access check: robots.txt read for 18 AI crawlers, your page requested as each crawler that fetches pages, and a scan for snippet controls that hide your text. On every plan, Free included.
• A ranked fix list with a priority and an effort estimate for each item, from every audit.
• Every answer in full, with the exact prompt sent and the sources cited.
• Competitors and history: tracked competitors from Starter, a saved score for every audit, and weekly or monthly re-audits from Starter.

The Free plan needs no card. Paid plans start with a 7-day trial that does take one. Read how the AI visibility audit works or compare plans and pricing.
