The best AI visibility audit services in 2026, honestly compared

Buyers now ask ChatGPT, Claude, Perplexity and Google which provider to choose, and those answers name three to five brands with no page two behind them. If your brand is one of the names, that channel works for you every day, and if it is missing, you lose deals you never knew existed.

We checked the published pricing, deliverables and engine coverage of 12 AI visibility audit services, monitoring tools and agencies on 23 August 2026, and we run audits by hand ourselves. The short answer: MentionShare for a verified audit with a fix plan, GoVISIBLE or the HubSpot AEO Grader to find out where you stand for free, and Otterly.AI for the cheapest ongoing monitoring. The eight worth your attention are compared below, with the math done and the cons stated for every one of them, ours included.

Disclosure: MentionShare publishes this article and appears in the list at position one. Every claim about our own service meets the same evidence standard as the rest, our cons are real ones, and the ranking basis is stated in the methodology section so you can disagree with it.

Quick picks

• Best audit + fix plan under agency prices: MentionShare, because a person reads every answer, verifies every claim and writes the fixes, from EUR 149.
• Best free starting point with a tracking path: GoVISIBLE, because its free audit is the most complete no-cost snapshot we found and the paid tier covers five engines at one flat price.
• Best budget monitoring: Otterly.AI, because $29 a month buys 15 prompts on four engines with unlimited team members.
• Best free one-time diagnostic: HubSpot AEO Grader, because it scores any brand, including a competitor, in under two minutes with no account.
• Best multi-country analytics: Peec AI, because it splits visibility by country on every self-serve tier.
• Best enterprise data depth: Profound, because its Enterprise tier tracks up to nine engines and no one else here matches its crawler and conversation data.
• Best for teams already on Semrush: Semrush AI Visibility Toolkit, because it adds AI tracking inside the interface your SEO team already uses.
• Best done-for-you program: Digital Elevator, because it executes the fixes for you in productized 30-day sprints.

What changed since the last check. On 23 August 2026 we re-read every pricing page. Three things moved since 14 August: Profound's plans are now publicly readable (Starter at $99 a month billed yearly, Growth at $399), Semrush now publishes its AI Visibility Toolkit at $99 a month per domain billed annually, and Digital Elevator now lists prices in the open (single sprints from $3,000, off-site campaigns at $3,495 per 30-day cycle). Peec AI's prices still render only in a browser. Otterly, GoVISIBLE and HubSpot were unchanged.

What is an AI visibility audit?

An AI visibility audit measures whether AI engines such as ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews name and recommend your brand when buyers ask what to use, and it documents what those engines get wrong about you. The output is a share-of-voice picture across engines, a list of verified errors traced to their sources, and a plan to fix both. Our guide to what a GEO audit covers and costs breaks the method down in detail.

Providers in this market do one or both of two jobs. Monitoring tracks how often your brand appears in AI answers, usually through an automated dashboard that runs a set of prompts on a schedule and charts the result. Auditing goes further: it reads what the answers claim, verifies those claims against your real facts, traces the errors to the directory, review page or stale URL feeding them, and hands you a prioritized fix plan.

The deliverable behind the price is the thing to check before you spend anything. Some entries below sell you a number that updates daily, some sell a one-time score, and some sell a document a human has verified. Each section says exactly what lands in your hands at the entry price, because that difference decides which option fits you more than any feature list does.

How we compared

Our comparison is research-based: we read each provider's live pricing and product pages on 23 August 2026 and recorded what the entry price includes: engines covered, prompt or question volume, seats, add-ons, and the concrete deliverable. We did not create accounts on the monitoring tools or run the same prompt set through each one, so nothing below claims a measured accuracy score for any of them.

Verification status is stated per entry. Otterly.AI, GoVISIBLE, HubSpot, Profound, Semrush, Digital Elevator, Athena, Scrunch, Rankscale and Ahrefs published machine-readable prices on the check date. Peec AI's tiers render only in a browser, so its price is quoted from a dated third-party roundup and labelled as such. Where a vendor hides a figure behind a sales call, the cell reads "Custom" and the prose says so.

The lens for ranking is what actually lands in your hands for the money: a score, a dashboard, or a verified report with a fix plan, judged for a small-to-mid-sized buyer with a marketing team of one to five people. Paid options that deliver the most for that buyer rank first, free diagnostics follow them, and enterprise platforms and agency programs priced for bigger budgets close the list. Our own evidence base, beyond the published prices, is the audit work we do by hand, cited below only in anonymized form.

Quick comparison

1. MentionShare: Best audit + fix plan under agency prices

Bottom line: the pick when you need to know what AI says about you, why, and what to change, verified by a person, at a one-off price below a single month of a mid-tier dashboard such as Otterly Standard or Profound Growth.

Pricing (mentionshare.com, 23 August 2026):

• Snapshot: EUR 149 one-off. 5 real buyer questions across all 5 engines, a share-of-voice leaderboard, and the errors AI states about you with ready-to-use fixes. Delivered in about 3 business days. The full EUR 149 is credited toward a Full Audit booked within 30 days.
• Full Audit: EUR 690 one-off. 30 questions across all 5 engines, a full leaderboard with mention rate, rank and sentiment, every documented error traced to its source, 15 or more fixes prioritized by impact, and 7 monthly re-measures of the same 30 questions included. Delivered in 5 to 7 business days. Monitoring continues afterwards at EUR 149 a month, cancel anytime.
• 14-day money-back guarantee on both. Prices exclude VAT.

MentionShare is an AI-visibility (GEO) audit service for B2B and B2C brands. A human expert, Laurynas Leskauskas, runs your real buyer questions through ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews, reads every answer, and reports who gets recommended instead of you, what the engines get wrong about you, and how to fix both. Of the eight entries here, only this one and the agency program at position eight put a human verifier between the AI answers and your report.

The deliverable is where the difference shows. Automated tools report how often you appear; an audit also reads what the answers say and checks it. In one delivered audit, ChatGPT quoted a client's monthly prices as annual, so every quote a buyer heard read about 25% too high, and public company databases named four different CEOs for the same company. A dashboard scores both situations as healthy, because the brand name appears and the sentiment reads fine. Every finding in a MentionShare report carries the exact claim, the source it was lifted from and the correct fact, and the fix plan arrives as cards with one owner, an effort estimate, the steps, the correction email already written, and a "done when" check. You can read a complete sample report before paying anything, and the method is documented step by step.

The cons are the flip side of hand-made work, and they are concrete. A Snapshot asks 5 questions once and a Full Audit 30, where Otterly's Standard tier re-checks 100 prompts daily and Scrunch tracks 350. Delivery takes days, where a scanner takes two minutes. Continuous measurement comes as monthly re-measures on the Full Audit, and there is no live dashboard to log into. And the capacity is one person's, which keeps the work honest and also caps how many audits ship in a month. If what you want is a live number over hundreds of prompts, a monitoring tool below fits better, and pairing one with a yearly audit is a reasonable setup.

Pros: human-verified findings with an evidence trail; errors traced to the source feeding them, which dashboards skip; fix cards with ready-to-use assets instead of advice; Claude included in every audit; 14-day money-back guarantee.

Cons: one-off audits with monthly re-measures and no live dashboard; 5 to 30 questions per audit where tools track hundreds of prompts; 3 to 7 business days of delivery time rather than minutes; one auditor's capacity.

Who it is for: a brand that needs to know what the answers actually tell its buyers and wants a plan its own team can start the same day. At EUR 149, the Snapshot costs less than one month of Otterly's Standard tier or Profound's Growth tier.

2. GoVISIBLE: Best free starting point with a tracking path

Bottom line: run the free audit this week whatever else you choose; the paid tier is the cheapest five-engine tracker we found.

Pricing (govisible.ai, 23 August 2026):

• Free AI visibility audit: a one-time dashboard snapshot, no credit card, about 2 minutes.
• GEO Flex: $79/mo for 50 prompts a month across 5 engines (ChatGPT, Gemini, Perplexity, AI Overviews, Copilot), 1 project, 1 region, unlimited users. Additional prompts at $15 each.
• GEO Enterprise: custom pricing, for teams with 10 or more projects, custom prompt quotas and unlimited regions.

GoVISIBLE pairs a genuinely free diagnostic with a mid-priced tracker. The free audit returns a one-time snapshot of prompt coverage, visibility by engine, share of voice by engine, competitor comparison, sentiment, source signals and a list of action priorities, which makes it the most complete no-cost snapshot in this comparison. As a first look at where you stand, it is a strong two minutes.

The paid tier turns the snapshot into ongoing tracking, and the price comparison is simple. $79 buys 50 prompts across five engines with unlimited users; Otterly's Standard tier buys 100 prompts across four engines for $189, and Otterly's $29 Lite remains the cheaper entry if 15 prompts are enough. What GoVISIBLE does not do is verify: the action priorities come from pattern rules, so a wrong price or a wrong company fact passes through unflagged as long as your name appears. The single region on GEO Flex also matters for brands selling into several markets, because the answers differ by region.

Pros: the most complete free snapshot in the category; five engines at one flat price; unlimited users on every plan.

Cons: automated analysis with no human verification; one region and one project on the entry plan; overage prompts at $15 each add up quickly.

Who it is for: any brand that has never seen its AI baseline, and teams that want flat-priced tracking without per-seat pricing afterwards.

3. Otterly.AI: Best budget monitoring

Bottom line: the cheapest credible always-on number, as long as you price the engine add-ons before you compare it with flat-priced options.

Pricing (otterly.ai/pricing, 23 August 2026):

• Lite: $29/mo for 15 prompts. Standard: $189/mo for 100 prompts. Premium: $489/mo for 400 prompts. Enterprise: custom, from $1,000/mo. Annual billing saves 15% ($25, $160 and $422 a month).
• All tiers track 4 engines: ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Unlimited team members.
• Add-ons per month: Claude $29 on Lite, $109 on Standard, $439 on Premium; Google AI Mode and Gemini $9, $59 and $149 respectively; an extra 100 prompts $99 on Standard and Premium.

Otterly.AI is the cheapest way in this comparison to watch your AI visibility continuously with a stated prompt allowance. The $29 Lite plan runs 15 prompts across four engines with unlimited team members, which is enough for a single product line's core questions.

The add-on structure is the thing to price out before you commit. Claude, Gemini and AI Mode all cost extra, and Claude scales steeply: $29 on Lite but $439 a month on Premium, so a Premium subscriber tracking Claude pays $928 a month, more than a MentionShare Full Audit costs once. For a small brand watching its core questions on the four included engines, none of that applies and the $29 entry is honest value; a brand whose buyers use Claude or Gemini needs to do the sum first.

Pros: cheapest paid entry with a stated allowance; unlimited team members on every tier; clean tier ladder with a 15% annual discount.

Cons: Claude, Gemini and AI Mode all cost extra, and Claude reaches $439 a month; monitoring only, with no verification of what the answers claim; 15 prompts is tight for more than one product line.

Who it is for: lean teams that want an always-on number on ChatGPT, AI Overviews, Perplexity and Copilot, and do not need Claude or Gemini tracked.

4. HubSpot AEO Grader: Best free one-time diagnostic

Bottom line: the fastest free way to find out whether you have a problem; run it on yourself and your top competitor, then decide whether the gap justifies a paid step.

Pricing (hubspot.com/aeo-grader, 23 August 2026): the Grader is free with no account required, described on the page as "a free, one-time diagnostic". HubSpot's continuous product, HubSpot AEO, is listed at $50 a month and tracks visibility week over week.

HubSpot's AEO Grader answers one question in under two minutes: how do an OpenAI model (GPT-5.4 mini on the check date), Perplexity and Gemini currently describe your brand. It returns a score out of 100 built from five weighted dimensions, sentiment (40 points), presence quality (20), brand recognition (20), share of voice (10) and market competition (10), with a written interpretation. It accepts any brand name, so it doubles as a quick probe of a competitor.

Treat it as a thermometer rather than a diagnosis. Three engines is the narrowest coverage on this list, the score is a snapshot that moves between runs, and it says nothing about why you are absent or what specifically to change. The 40-point weight on sentiment also means a brand that is rarely mentioned but politely described can score better than a brand mentioned often with a caveat, which is worth knowing before you read the number. As a free first step before spending money anywhere, including with us, it is exactly right.

Pros: genuinely free with no account; works on any brand including competitors; a published scoring rubric; results in about two minutes.

Cons: three engines only; a one-time snapshot with no tracking; a score without causes or a fix path.

Who it is for: anyone who wants a number in two minutes before deciding whether to spend anything.

5. Peec AI: Best multi-country analytics

Bottom line: the analytics pick for brands selling across several countries, once you have confirmed the current tier prices in your own browser.

Pricing (peec.ai/pricing, 23 August 2026): four tiers named Starter, Pro, Advanced and Enterprise, billed annually. The prices render only in a browser, so we could not machine-verify them; a third-party roundup updated on 29 July 2026 (Geoptie) listed Starter at $95 a month for 50 prompts and 1 project. A free trial is offered.

Peec AI earns its place on country-level reporting. Every self-serve tier tracks daily and lets you choose three models from its list of six (ChatGPT, AI Mode, AI Overviews, Copilot, Perplexity, Gemini), Pro and Advanced add three countries per project, and the platform advertises tracking across all countries. For a brand selling into several European markets, that split is the differentiator, because the same question produces different recommendations in different countries.

Two constraints decide whether it fits. Engine choice is capped at three models per self-serve tier, and Claude is absent from the published self-serve list, so a brand whose buyers use Claude gets no data there. And like every dashboard on this list, it measures presence rather than truth, so pair it with a periodic verification pass if a wrong price or a wrong fact about you would cost deals.

Pros: country-level tracking on every tier; daily tracking; a free trial to test the fit.

Cons: prices are not published in machine-readable form, so comparison shopping takes manual work; three models per self-serve tier, with Claude not listed; no verification layer.

Who it is for: multi-market brands whose buyers use ChatGPT, Google's AI surfaces, Perplexity or Copilot and who want the answers split by country.

6. Profound: Best enterprise data depth

Bottom line: the enterprise pick when crawler-level evidence and compliance decide the purchase; small teams pay less elsewhere for more coverage.

Pricing (tryprofound.com/pricing, 23 August 2026):

• Starter: $99/mo billed yearly. 50 prompts tracked, 1,500 responses a month, ChatGPT only, 1 seat.
• Growth: $399/mo billed yearly. 100 prompts, 9,000 responses a month, 3 engines (ChatGPT, Perplexity, Google AI Overviews), 3 seats. A free trial is offered on this tier.
• Enterprise: custom pricing, up to 9 engines including Gemini, Copilot, Grok, DeepSeek and Claude.

Profound is the most established enterprise platform in AI visibility, and its differentiation is data depth nothing else here matches: crawler analytics showing which AI bots read your site and which pages they fetch, and a conversation explorer built on a large real-prompt dataset. That is the kind of evidence a procurement team and a security review both ask for.

The entry tiers are narrow for the price. Fifty prompts on one engine and one seat at $99 a month, billed yearly, buys less coverage than GoVISIBLE's five engines at $79, and Claude sits behind an Enterprise conversation. The published ceiling before custom pricing is 100 prompts across three engines at $399 a month. For a small B2B buyer that math rarely works; for an enterprise that needs crawler-level evidence and nine-engine coverage, nothing else on this list is a substitute.

Pros: crawler and conversation data no competitor here matches; up to 9 engines at Enterprise; public pricing for the two self-serve tiers.

Cons: entry tier covers a single engine and a single seat; self-serve prices assume yearly billing; Claude and most engines only at Enterprise.

Who it is for: enterprises with procurement and security requirements, and teams that want to see which AI crawlers actually read their site.

7. Semrush AI Visibility Toolkit: Best for teams already on Semrush

Bottom line: a sensible extension if Semrush is already home; teams starting fresh get more coverage for the money from a purpose-built option.

Pricing (semrush.com/pricing/ai, 23 August 2026): $99 a month per domain, billed annually, for 25 custom prompts tracked daily, 1 domain, and mentions from ChatGPT, Google AI, Gemini and Perplexity. Additional users from $45 a month; report add-ons at $10 and $20 a month. Semrush offers a 7-day free trial.

The AI Visibility Toolkit folds AI tracking into the Semrush interface your SEO team may already use daily: prompt tracking, brand mentions, competitor analysis, prompt research and an AI-readiness site audit, next to your existing keyword and ranking data. Adopting no new vendor is a real benefit for a team whose reporting already lives in Semrush.

The structure to check is the multiplication. $99 covers one domain and 25 prompts; a second domain is another toolkit, and each additional user starts at $45 a month, so three teammates on one domain pay about $189 a month before the underlying Semrush subscription. Otterly's Standard tier at the same $189 tracks 100 prompts with unlimited team members, and Claude is on neither plan without an add-on or an upgrade. Run your own seat and domain math before deciding the convenience is free.

Pros: one interface for SEO and AI visibility; no new vendor to onboard; a strong surrounding dataset and an AI-readiness audit of your own site.

Cons: 25 prompts per domain is the smallest allowance of the paid tools here; per-domain and per-user pricing multiplies quickly; Claude is not listed.

Who it is for: marketing teams whose reporting already lives in Semrush and whose buyers use ChatGPT, Google and Perplexity.

8. Digital Elevator: Best done-for-you program

Bottom line: the pick when your team cannot own the fixes; get the audit-level findings first so you know what you are paying the agency to execute.

Pricing (thedigitalelevator.com, 23 August 2026): a free AI Visibility Report with a strategist walkthrough "for qualified teams"; single sprints from $3,000; ongoing off-site campaigns at $3,495 per 30-day cycle; a full three-pillar program typically $9,000 to $24,000 and up. No retainer is required.

Digital Elevator represents the agency end of this market, and it earns its place by aiming at lean teams rather than enterprises and by publishing its prices, which most agencies in this category still do not. Its program runs three pillars, technical and measurement (schema, entity data, tracking of AI-referred sessions), content and extractability (definition, comparison and FAQ pages), and off-site signals (brand mentions, community presence, editorial placements), tracked across ChatGPT, Perplexity, AI Overviews and Gemini, and the agency does the work itself.

The price gap is the decision point. A single sprint costs about four MentionShare Full Audits, and the full program, at $9,000 and up, costs well over ten; what the extra money buys is hands executing the plan rather than better findings. Buy the execution when you lack the hands, and buy the audit when your own marketing team can ship fixes from a ready-made plan.

Pros: execution included, with the agency doing the work; productized sprints with no required retainer; published prices; SMB-oriented among agencies.

Cons: the cheapest paid step is $3,000; the free report is gated to qualified teams; you still supply product knowledge and approvals.

Who it is for: companies with budget and no in-house hands to execute content and off-site work.

How to choose an AI visibility audit service

Four checks decide most purchases: which engines your buyers actually use (Claude is the one most often gated or priced extra), how many of your real buyer questions the price covers, whether the answers are split by country where you sell, and what the deliverable is. The last one is the criterion vendor pages skip, so it gets its own section.

Does the price buy a verified report or an unverified score?

A score or a dashboard tells you how often your name appears; a verified report tells you what the answers claim, whether the claims are true, and which source put each wrong claim there. That distinction decides what you can do on Monday morning. In one 25-answer audit panel for an ecommerce software client, four of the five answers to cost questions quoted competitor prices word for word from public pricing pages, and one engine still recommended a vendor whose domain no longer resolves. A mention counter registers both answers as normal; a person reading them sees a pricing page to publish and a stale directory record to fix.

The second half of the same criterion is the question set. Most dashboards run a generic prompt pool or prompts you type yourself, while an audit starts from the questions your buyers actually ask, which your sales team can list in an hour. Ask any vendor two things before paying: who reads the answers, and whose questions get asked. The answers sort this whole list in a minute.

Which one should you choose?

A small or mid-sized brand that has never seen its baseline: run GoVISIBLE's free audit and the HubSpot Grader today, then buy a MentionShare Snapshot at EUR 149 for the verified picture and the first fixes.

A marketing team that wants to know what is wrong and fix it: a MentionShare Full Audit at EUR 690, with the 30-question leaderboard, every error traced to source, the fix cards, and seven months of re-measures included.

A lean team that wants a live number: Otterly.AI at $29 a month if the four included engines match your buyers, or GoVISIBLE at $79 if you need Gemini and Copilot in the same price.

A multi-country brand: Peec AI, after confirming the tier prices in your browser. An enterprise with procurement and security requirements: Profound. A team already living in Semrush: the AI Visibility Toolkit. A company with budget and no hands: Digital Elevator.

Other options we considered

Four more services had public prices on the check date and did not make the list of eight, each for a reason that may be your reason to pick it.

• Athena (Essential free with 300 credits, Starter $295 a month for 3,600 credits, Enterprise custom) covers ChatGPT, Perplexity, AI Overviews, Gemini and Claude and sells usage in credits, one credit per AI response. The free tier is a legitimate way to test Claude coverage; the $295 entry sits above GoVISIBLE and Otterly for a similar dashboard deliverable.
• Scrunch (Starter $250 a month billed annually or $300 monthly for 350 custom prompts; Growth $417 or $500 for 700; 7-day trial) includes ChatGPT, Claude, Gemini, Perplexity, Google AI Mode and Overviews, and Meta. The prompt volume per dollar is strong; the entry price sits in a mid-market bracket this comparison does not rank.
• Rankscale (Essentials $20 a month, Pro $99 for 1,200 credits and up to 4,800 tracked answers, Growth $385, Enterprise $780; 7-day Pro trial) monitors ten or more engines including Claude, Grok, DeepSeek and Mistral. The $20 tier is the cheapest paid entry we found, and its allowance is not stated on the pricing page, so it could not be compared like for like with Otterly.
• Ahrefs Brand Radar (an add-on at EUR 179 a month for selected platforms or EUR 654 for all platforms with 2,500 custom-prompt checks) tracks AI Overviews and AI Mode, ChatGPT, Perplexity, Copilot and Gemini over a large prompt database. It is an add-on to an Ahrefs subscription, so the true starting cost depends on a plan this article does not price.

The short answer

The best AI visibility audit services in 2026 split by what lands in your hands. For a verified report with a fix plan, MentionShare from EUR 149, with the full sample report readable before you pay and both plans on the pricing page. For a free baseline this week, GoVISIBLE's free audit or the HubSpot AEO Grader, in under five minutes combined. For the cheapest ongoing tracking, Otterly.AI at $29 a month after pricing the add-ons for your engines. Peec for multi-country analytics, Profound for enterprise data, Semrush for teams already on Semrush, and Digital Elevator for done-for-you execution.

The one step that costs nothing: run a free diagnostic today and see whether the engines mention you at all. Whatever the score says, you will know which half of this list you need.
