Best AI Search Visibility Tools (2026), Tested

“AI search visibility tool” is a label for at least four different products. Some check whether AI crawlers can reach and read your pages. Some ask a language model to guess whether you would be recommended. Some run real prompts and record the answers. The paid ones repeat that over time and compare you with competitors. A tool can be good at one of these jobs and silent on the others.

To see what the free options really do, we ran them on our own brand, Web Aloha (webaloha.co), on 26 September 2026: same brand, same day, a fresh logged-out browser, no accounts and no emails. We tried eight free tools under those rules and five returned results. Here is what each one measured, what we could verify, and which job it suits.

The short answer

The most useful finding: none of the free tools that returned a result showed us what an AI search answer to a buyer’s question actually says. Two checked technical readiness. Three were model-based: HubSpot asks each model how it describes the brand from its training data, while Rank Prompt and SEOcrawl ask one model to estimate whether you would be named, and both say so on the results page.

How we tested

We wrote the jobs, criteria and rules down before running anything, then applied them to every tool:

• Date: all runs on 26 September 2026, within about 30 minutes.
• Brand: Web Aloha, webaloha.co, homepage https://webaloha.co/.
• Browser: Playwright with headless Chromium, a fresh profile per tool, logged out, English (UK), connecting from Lithuania.
• Inputs: the homepage URL for readiness tools; “Web Aloha” or webaloha.co for brand tools. Where a tool asked for a business description we used “Worldwide”, “Web design and digital marketing” and “Web design, SEO and GEO for small businesses”.
• Rules: no account, no email, no payment and no personal data. Non-essential cookies declined. A CAPTCHA, bot check or email gate ended the test for that tool, and we never bypassed one.
• Verification: we checked every claim against something outside the tool: the live robots.txt, sitemap, llms.txt and page markup for readiness findings, and a same-day manual prompt panel for anything about mentions or citations.
• Our own tool: its public page uses a Cloudflare bot check (Ahrefs and Semrush use similar protection), so under these rules it would have been blocked too. We ran the same code from a local build and called its API directly. Judge its results with that in mind.

We scored each tool we ran from 0 to 2 on five criteria: method transparency, verifiable results, fit for its job, honest claims and actionable advice. The scorecard is further down.

Readiness checks: can AI crawlers reach and read your pages?

Readiness is the one job a free tool can do completely, because it is deterministic: fetch the page and robots.txt, apply the rules, parse the markup. Two tools ran cleanly.

Web Aloha AI Search Visibility Checker (free, no account). Our tool scored the homepage 100 out of 100: all 8 scored checks passed (page status, HTTPS, access for OAI-SearchBot, Claude-SearchBot, PerplexityBot and Googlebot, no noindex, language, H1 and title). It also listed 15 unscored observations, including 4 JSON-LD blocks that parsed (Organization, WebSite, WebPage, ItemList) and about 940 words of text in the server-returned HTML. We checked the crawler rules and schema types against the live site, and they matched. One honest caveat: the name says “visibility”, but it measures readiness. It does not run prompts or track citations, and the tool page says so next to the input.

Answer Visibility Lab AI Crawlability Checker (free, no account). It also scored the site 100 (“AI crawl-ready”). It covers a different slice: robots.txt, the Sitemap directive, sitemap.xml, llms.txt, a homepage noindex check, and a matrix of eight crawlers (including GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Googlebot and Bingbot) across priority paths. Every finding matched the live files, and it states under the score that it does not guarantee citations or recommendations.

The two overlap on crawler access and differ elsewhere. Answer Visibility Lab checks site files such as sitemap.xml and llms.txt. Ours checks the page itself (structured data, server-rendered text, headings and indexing headers) and reports user-triggered fetchers such as ChatGPT-User separately, without scoring them. Use either or both. Just don’t read 100 as “AI search recommends us”: the next two sections show why.

Model-based checkers: what a model thinks of you

These tools don’t observe AI search answers. They ask a language model about your brand, or ask it to predict whether you would be named. That can prompt useful reflection, but it is not a measurement of AI search.

HubSpot AI Search Grader (free; the full report needs an email). We entered the company name, “Worldwide”, the industry and the services. Without an email it showed three scores out of 100: OpenAI 32, Perplexity 52 and Gemini 37, each split into brand recognition, market score, presence quality, sentiment and share of voice. HubSpot says the grader asks each model how it characterises the brand based on its training data. The answers behind the scores are only in the full report, which asks for an email, so we could not check any of them. A second run with identical inputs gave identical scores. That fits HubSpot’s “deterministic scoring” claim, although we can’t tell whether it re-ran or served a stored result.

Rank Prompt free checker (free, no account). With our brand, the closest industry option (“Marketing Agency”) and our category, it returned “0 of 3 assistants would likely name your brand” for ChatGPT, Perplexity and Gemini, each with a one-line reason. Directly under the result it says the verdicts were estimated by an OpenAI model, not live answers from each assistant. That was the clearest disclosure we saw. The question it estimated for is not shown, so there is nothing to re-check.

SEOcrawl AI Visibility Checker (free, no account). It scored us 22 out of 100 (“Poor”), said all four engines “rarely” name us, suggested nine prompts and a six-step plan, and named six “competitors” that it said are surfacing in AI answers for prompts where we should appear. The brand facts it listed were accurate: 94 free tools, 8 countries and a result from one of our case studies. But the competitor claim reads as an observation, while the report’s own footer calls it an AI-generated estimate, not a live measurement. None of those six agencies appeared in any of the 12 answers from our same-day prompt panel. Our prompts were different, so that doesn’t disprove the claim, but nothing supports it either. One of its three high-priority actions asks for an llms.txt file and Organization schema, and both were already live on our site. It also published the report at a public (noindexed) URL.

The pattern across all three: plausible, broadly fair for a small agency, and impossible to verify. Treat them like asking one well-read person for their impression.

Observed answers: what AI search actually said

The only way to know what an AI answer says is to look at it. On the same day we ran our fixed six-prompt panel, the method described in our guide to measuring GEO and AI visibility, in a fresh, logged-out browser from Lithuania:

None of the four discovery prompts (two agency recommendations, a font tool and an internal-link tool) named us on either platform. So the estimates were broadly right about generic “which agency” questions. What they could not see is the one thing that did work: a specific, evidence-seeking question, answered with our published case study. That is the difference between a guess and an observation, and it is why a readiness score of 100 and an estimate of 22 can both be “true” without telling you what to do next.

Twelve answers on one day are a snapshot, not a trend. Answers vary between runs, locations and accounts, so repeat the same prompts on a schedule before drawing conclusions.

Monitoring tools we could not test

Ongoing monitoring (the same prompts re-run on a schedule, with competitors and share of voice) is where most paid tools sit. None of these could be tested without an account, an email or payment, so we only report what each vendor states on its own site, checked on 26 September 2026. We have not verified how any of them collects answers. Prices can differ by location; euro prices are as shown to a connection from Lithuania.

• Ahrefs free checker and Brand Radar. Not tested: the free checker showed a Cloudflare bot check. Ahrefs describes its data as 449M+ search-backed prompts across ChatGPT, Gemini, Perplexity, Copilot, AI Overviews and AI Mode. Listed price: free preview; AI Visibility Index from $199/month; custom prompts from $50/month.
• Semrush free checker and AI Visibility Toolkit. Not tested: the free checker rejected our request as suspicious. Semrush says it draws on 26M+ prompts and responses across ChatGPT, Gemini, AI Mode and AI Overviews, with 3 free checks a day. Listed price: Toolkit $99/month per user or domain, no free trial.
• Otterly.AI. Not tested: account needed (free trial). Covers ChatGPT, Google AI Overviews, Perplexity and Copilot, with Claude, AI Mode and Gemini as add-ons. Listed price: Lite €29/month (15 prompts), Standard €189/month (100), Premium €489/month (400).
• Peec AI. Not tested: account needed (free trial). Tracks 3 models of your choice per plan, daily. Listed price: Starter €85/month (50 prompts), Pro €205/month (150), Advanced €425/month (350).
• Profound. Not tested: account needed for the trial. Trial: 50 prompts daily for 7 days on ChatGPT, Gemini and AI Overviews. Enterprise pricing on request.

A person in a normal browser may not see the Ahrefs and Semrush bot checks, so their free checkers are worth trying yourself. We also tried Authority Radar’s free check, which asked for an email before showing anything.

Scorecard for the tools we ran

Each criterion is scored 0 to 2. The scores rate how well a tool does the job it claims and how honestly it presents its results. They are not a ranking: a readiness checker scores well on transparency because readiness is easy to verify, but it cannot tell you whether AI answers mention you.

The scores that need explaining:

• Our own checker loses a point on honesty. Its name says “visibility” while it measures readiness. The scope note sits next to the input, but the name alone can mislead.
• Rank Prompt gets full marks on honesty for stating, directly under the verdict, that it was estimated by an OpenAI model and is not a live answer.
• SEOcrawl scores 0 on honesty because its headline presents an estimate as an observed fact, with urgency copy. The notes calling it an estimate come further down the report.
• HubSpot scores 0 on verifiability because the answers behind its scores are only in the emailed report.

Questions to ask before you pay for monitoring

Paid monitoring tools say they run your prompts on the platforms themselves. Before you pay, ask:

1. Which prompts? Can I write my own and see the exact wording?
2. Which platforms and modes (ChatGPT with or without search, AI Overviews, AI Mode, Perplexity), logged in or out, and from which country?
3. Can I see the raw answer and the cited URLs behind every number?
4. How often is each prompt re-run, and how are answers that change between runs counted?
5. How is share of voice calculated, and which competitors are included?
6. Can I export the data?

If a vendor can’t answer these, its dashboard is a score you can’t check.

What we would do for a small business

1. Run a readiness check on your most important pages and fix anything that blocks crawlers or hides text. Our AI Search Visibility Checker is free. Treat the result as a foundation, not an outcome.
2. Write 10 to 20 questions your buyers really ask, including a few specific, evidence-seeking ones about your work. Run them monthly on the platforms your customers use, logged out, and save the answers.
3. Track AI referral visits and enquiries in analytics, separately from mentions.
4. Pay for monitoring only when the manual panel gets too slow for the prompts, platforms or competitors you need, and choose a tool that shows its raw answers.

Our guide to measuring GEO and AI visibility has the full prompt-panel template. If you would rather hand the work over, our GEO services cover the technical fixes, citation-focused content and ongoing AI visibility monitoring.
