The best AI visibility tools measure how often your brand shows up in sample responses from ChatGPT, Google AI Overviews, AI Mode, Perplexity and other engines, because the order of the lists those engines return almost never repeats. To choose, look at three things: which engines matter in your market, how many prompts you can afford per month, and whether you just want to measure or want the tool to also suggest and publish changes.
The data point that organizes this category came out on January 27, 2026. SparkToro, the audience research company run by Rand Fishkin (co-founder of Moz, one of the first SEO software companies), published a study in which 600 volunteers ran 12 prompts 2,961 times across ChatGPT, Claude, and Google (AI Overviews or AI Mode). It found less than a 1-in-100 chance that ChatGPT or Google will return the same list of brands twice, and about 1 in 1,000 that they’ll return it in the same order. Fishkin concludes that ranking within a single response is nearly useless, and that visibility share across many runs is “(probably)” a reasonable measure. The study was done with Patrick O’Donnell of Gumshoe, a Seattle startup that sells a tool in this same category; Fishkin acknowledges this as a possible conflict of interest in the text.
Pick based on your case:
- Small team that wants the tool to suggest and publish changes: Omnia.
- Measuring on the smallest budget: OtterlyAI, or Promptwatch Explore (free) if ChatGPT alone is enough.
- Measuring across all engines at a mid-range price, or an agency with multiple clients: Promptwatch.
- Already paying for Ahrefs or Semrush: their AI visibility module.
- Large company with SSO: Profound, Scrunch, AthenaHQ, or Promptwatch Business and Enterprise.

How we evaluated the AEO tools
AEO (answer engine optimization) is the work of getting a brand to appear in AI engine responses, one piece of the shift we described in our story on agentic search. We applied the same five criteria to all nine tools:
- Engines covered. Which ones come by default and which cost extra or are activated on request: ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, Claude, Copilot and others.
- Volume and measurement method. How many prompts each plan includes, how often they run, and whether the tool explains how it obtains responses (by simulating a browser or via API). More prompts reduce the noise described by SparkToro.
- Sources and competitors. Whether it shows which pages the engines cite and whether it compares your brand against competitors.
- Measure or execute. Whether it only reports or also recommends, drafts, or publishes, and with what level of human control.
- Price and fit. Public pricing, free trial, countries and languages per plan, and included users.
This guide is based on pricing pages, official documentation, and press cited by name, reviewed on November 12, 2026. Prices don’t include taxes and are listed in the currency each company publishes. We didn’t run our own test with the same prompts across multiple tools, so we don’t say which one measures best. Within each group, the order is alphabetical.
Specialized AEO tools
AthenaHQ
An AI visibility platform with agents that suggest actions both on-site and off-site.
- Engines: claims to cover 11 models, including ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, Claude, Copilot, and Grok.
- Pros: on-page and off-page actions, a “Content optimization agent,” and integration with Shopify and Webflow.
- Cons: a high entry price for a small team, and a credit-based model that forces you to calculate consumption.
- Price: according to AthenaHQ‘s plans page, Essential is free, with $25 in credit. Starter costs $295 per month with 3,600 credits (1 credit equals 1 AI response). API and extra credits are billed separately. The page has a monthly/annual toggle, and we didn’t verify whether price changes.
Omnia
An AI visibility platform with an agent, Omnia Agent, that analyzes gaps, builds a prioritized backlog of actions, and creates or updates content, always with your approval before publishing. It’s built by Omnia Agents SL, a Madrid startup founded in April 2025 by Daniel Espejo and Miguel Fernández, which raised €3.5 million in a pre-seed round in October 2025 led by Visionaries Club, with Kfund and Baobab Ventures, according to EU-Startups and Europa Press.
- Engines: by default, ChatGPT, Perplexity, Google AI Overviews, and Google AI Mode. Claude, Gemini, and Microsoft Copilot are available on request, up to seven total. Omnia says it updates daily via real-browser simulations; that’s a company claim, with no independent audit.
- Pros: every plan includes share of voice against competitors, citations, prompt discovery, sentiment, an action backlog, publishing with approval, API and MCP with read and write access, and unlimited brands, countries, and languages. It also lists third-party outreach and CMS integration, which we didn’t verify.
- Cons: the entry plan includes 25 prompts, below the 50 to 100 per topic that OtterlyAI itself recommends for stable data. Gemini, Claude, and Copilot don’t come by default, exporting data requires the Pro plan, and it doesn’t publish SSO on its plans. It has little independent public track record. Its page claims that “most AI visibility tools stop at monitoring” (our translation), and that doesn’t hold up: Promptwatch, Peec AI, Profound, AthenaHQ, and Scrunch also offer agents or optimization.
- Price: Growth costs €79 per month billed monthly or €63 billed annually (25 prompts). Pro, €279 or €223 annually (100 prompts, data export, and Slack support). Enterprise, from €499 or €399 annually (200 prompts or more). An extra 25 prompts cost €89 per month. It offers a 14-day free trial with no credit card, reachable through our affiliate link, and public pricing on its site.
OtterlyAI
An AI visibility monitoring tool with cheap entry-level plans.
- Engines: ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Google AI Mode, Gemini, and Claude; Lite covers 4 of the 7, and each Claude response uses 3 credits.
- Pros: unlimited users, brands, competitors, countries, and languages on every plan; citation tracking, recommendations (3 per week on Lite), and a GEO (generative engine optimization, a sibling term to AEO) audit. Its FAQ offers a data point useful for the whole category: it recommends tracking between 50 and 100 prompts per topic or market, and says that in its own study, going from 10 to 100 prompts cut coverage variation by around 73%.
- Cons: by that same standard, its Lite plan (16 prompts) falls short. Lite doesn’t allow buying extra credits, and execution is limited to recommendations.
- Price: according to OtterlyAI‘s pricing page, Lite is €29 per month (16 prompts, daily). Standard €189 (120 prompts, API and MCP). Premium €489 (403 prompts). 15% off on annual plans, plus a free trial.
Peec AI
An AI visibility platform that adds engines beyond the United States.
- Engines: ChatGPT, Perplexity, AI Overview, AI Mode, Gemini, Naver AI Briefing (from the South Korean search engine Naver), ERNIE (from Baidu, the Chinese search engine), and Bing AI Mode, plus API-based models. Each plan allows 3 active engines.
- Pros: unlimited users on every plan, and a plans table that includes gap analysis, recommended actions, agent actions, and credits for a dedicated agent (500 on Starter).
- Cons: only 3 active models per plan, and Starter is limited to 1 country, a problem if you’re tracking Argentina and Spain at the same time. We didn’t verify whether it offers a free trial.
- Price: according to Peec AI‘s pricing page, Starter is $95 per month (50 prompts, 1 country, 1 project). Pro $245 (150 prompts, 3 countries). Advanced $495 (350 prompts, 5 projects, Looker Studio). Enterprise is custom, with SSO, API, and up to 26 models.
Profound
A platform for large companies that bills itself as an “AI Marketer,” with agents and suggestions.
- Engines: up to 10 on Enterprise; the trial covers ChatGPT, Gemini, and Google AI Overviews.
- Pros: Agent Analytics, which shows bot and AI traffic to your site through Cloudflare, Vercel, WordPress, and other integrations; SSO/SAML and SOC 2 on Enterprise.
- Cons: it doesn’t publish the price of any paid plan.
- Price: according to Profound‘s pricing page, there’s a 7-day free trial with 50 daily prompts, 1 language, and 1 region. Enterprise is custom.
Promptwatch
An AI visibility platform that measures mentions, citations, and sentiment, and on its higher-tier plans writes and publishes content. It’s built by Promptwatch B.V., an Amsterdam-based company with an office in New York, founded in 2025 by Gijs de Groot and Klaas Foppen, which raised €6 million in a seed round on July 14, 2026, led by Seed + Speed Ventures, with Blum Ventures and Arches Capital, according to Tech.eu, a European tech outlet.
- Engines: its pricing page lists ChatGPT, Google AI Overviews, Google AI Mode, Microsoft Copilot, Perplexity, Claude, Gemini, Meta AI, DeepSeek, Mistral, Amazon Alexa, Codex, OpenCode, and Claude Code; its FAQ adds Grok. On paid plans there’s no cap on engines: the limit is responses per month. It doesn’t list Naver or ERNIE.
- Method: according to its documentation, it collects responses from the interfaces of ChatGPT, Gemini, AI Overviews, Perplexity, and others, and uses the provider’s API for some models, like Claude, DeepSeek, and Mistral. There’s no independent audit of that method.
- Pros: Essential includes every engine it lists, unlimited seats, country-level tracking, Agent Chat, recommended actions, MCP, and API. Professional adds content writing and refreshing (5 AEO articles per month) and crawler logs. Business adds the Content Agent, which can publish to WordPress, Webflow, or Framer with review or fully automatically.
- Cons: Essential doesn’t write content, and publishing only arrives with Business, at $579 per month. Essential includes 6,000 responses per month: 50 prompts across four engines, every day, already add up to 6,000 in a 30-day month (our math, assuming one response per prompt per engine), so that’s not enough to run every engine daily. The published website and support are in English and Dutch, and promptwatch.com/es redirects to the English homepage. We didn’t verify the app’s language.
- Price: Explore is free (10 prompts, ChatGPT only, no country-level tracking), though it doesn’t show up as a card in the page’s default view. Essential costs $95 or €85 per month (50 prompts); Professional, $245 or €205 (150 prompts); Business, $579 or €499 (350 prompts, tracking as often as hourly). Annual billing costs 10 times the monthly rate, about 17% less. Agency plans start at $199 or €170 per month, without AEO articles or a knowledge base. 7-day trial on paid plans.
Scrunch
An AI visibility platform that includes site audits.
- Engines: Core covers ChatGPT, Perplexity, Google AI Overviews and Copilot. Enterprise adds Claude, Gemini, Meta AI, Google AI Mode and Grok.
- Pros: 125 prompts and 5 users on the entry plan, plus 5 site audits.
- Cons: Core is limited to 1 country and 1 language, with no Google AI Mode or Gemini. The page doesn’t clarify whether the price is billed monthly or annually.
- Price: according to Scrunch’s pricing page, Core costs US$250 per month (125 prompts, 5,000 responses per month), with a 7-day trial. Enterprise is custom-priced.
AI visibility modules from SEO suites
Ahrefs Brand Radar
A module from Ahrefs, the SEO suite known for its backlink and keyword database.
- Method: it explains in detail how it measures. Its AI Visibility Index runs more than 558 million prompts derived from its keyword database across AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot, with a monthly re-test; the custom prompts also add Claude.
- Pros: a benchmark of your category with no setup required, if your brand already has search demand.
- Cons: Ahrefs warns that the index has limited coverage for brands with little or no search volume. The base plans include few prompts, and we didn’t verify whether the index can be purchased without an Ahrefs plan.
- Price: according to Ahrefs’s pricing page and the Brand Radar page, every paid plan includes custom prompts (Lite 5, Standard 10 and Advanced 20 per day); Ahrefs Lite costs US$129 per month. Prompt packages start at US$50 per month. The AI Visibility Index costs US$199 per month per engine or US$699 per month for all of them.
Semrush AI Visibility Toolkit
A module from Semrush, the other major SEO suite.
- Engines: according to Semrush’s knowledge base, prompt tracking covers ChatGPT Search, Google AI Mode and Gemini; visibility reports add AI Overviews, and Brand Performance reports add Perplexity.
- Pros: the list of regions in Visibility Overview includes Argentina, Spain and Uruguay.
- Cons: few prompts for the price, per-user licensing, and no free trial.
- Price: according to Semrush’s help center, it costs US$99 per month with 25 prompts; each extra user costs another US$99, and 50 extra prompts cost US$60. It’s also included in Semrush One, starting at US$199 per month billed monthly or US$165.17 billed annually, with 50 prompts.
We left out Writesonic and Goodie: they’re still active, but we didn’t complete verification of the five criteria.
Comparison table of AI visibility tools
The table summarizes what each company had published as of November 12, 2026; the number of engines isn’t directly comparable across tools, since each plan counts them differently.
| Tool | Entry price | Prompts in the entry plan | Engines in the entry plan | Countries and languages | Executes changes | Free trial |
|---|---|---|---|---|---|---|
| AthenaHQ | US$295/month | Credit-based (3,600 responses) | 11 models | Country level | Yes, content agent and actions | Free plan with US$25 credit |
| Omnia | €79/month (€63 annual) | 25 | 4 (up to 7 on request) | Unlimited | Yes, publishes with approval | 14 days |
| OtterlyAI | €29/month | 16 | 4 of 7 | Unlimited | Recommendations | Yes |
| Peec AI | US$95/month | 50 | 3 of your choice | 1 country, unlimited languages | Recommendations and agent actions | Not verified |
| Profound | No public price | 50 (7-day trial) | 3 in the trial | 1 region in the trial | Agents (“AI Marketer”) | 7 days |
| Promptwatch | US$95/month (€85); Explore is free | 50 (10 in Explore) | All those listed in paid plans; only ChatGPT in Explore | Country level, in paid plans | Writing from Professional; publishing from Business | 7 days |
| Scrunch | US$250/month | 125 | 4 | 1 country, 1 language | Page optimization (1/month) | 7 days |
| Ahrefs Brand Radar | Included with Ahrefs (Lite US$129/month) | 5 per day | All those in the index plus Claude | Not verified | No | Not verified |
| Semrush AI Visibility Toolkit | US$99/month | 25 | 3 in Prompt Tracking | 220+ countries | Recommendations | No |
If you divide the entry price by the included prompts, the monthly cost per prompt works out as follows (our own math, not directly comparable across tools since engines and frequency vary): OtterlyAI Lite, €1.81; Promptwatch Essential, €1.70 or US$1.90; Peec AI Starter, US$1.90; Scrunch Core, US$2; Omnia Growth billed monthly, €3.16; Semrush, US$3.96.
The best AI visibility tools for your situation
A small marketing team with no AEO specialist, who wants the tool to propose and publish changes
Omnia: Growth to test it, Pro if you need more than 25 prompts. Among the tools we verified, it’s the one that most explicitly claims to publish changes with approval from its entry plan, at €63 per month billed annually. Its limits: 25 prompts and 4 engines by default. Promptwatch writes content from Professional (US$245) and publishes via its Content Agent from Business (US$579), not from Essential. If this is you, you can try Omnia for 14 days with your own prompts before paying.
Measuring on a minimal budget, across multiple countries and languages
OtterlyAI, knowing that Lite (16 prompts) falls below its own recommended volume. If ChatGPT alone is enough, Promptwatch Explore is free, with 10 prompts and no country-level tracking.
Measuring across all engines, at a mid-range price
Promptwatch Essential: US$95 or €85 per month, 50 prompts and all the engines it lists. Peec AI charges the same on Starter, but limits you to 3 active engines and 1 country. In the Promptwatch vs. Peec comparison, Promptwatch’s ceiling is its 6,000 monthly responses; Peec’s is its 3 engines.
An agency with multiple clients
Promptwatch, with agency plans starting at US$199 per month, unlimited projects and usage measured by responses. If your clients need Naver or ERNIE, Peec AI.
You already pay for Ahrefs or Semrush
Start with the included module or add-on before signing up for another tool. For a category benchmark without having to build prompts, use Ahrefs’s AI Visibility Index, if your brand has search volume.
A large company with SSO, multiple brands and a custom budget
Profound, Scrunch Enterprise, AthenaHQ Enterprise, or Promptwatch Business and Enterprise (Promptwatch’s SSO is only in Enterprise).
AEO tools for Latin America and Spain
For anyone measuring Argentina and Spain at the same time, country limits matter more than price. Scrunch Core (1 country and 1 language) and Peec AI Starter (1 country) fall short. Omnia and OtterlyAI offer unlimited countries and languages. Promptwatch Essential allows country-level tracking, but each monitor is fixed to one language and one location, and everything shares the 6,000-response monthly cap. Semrush lists Argentina, Spain and Uruguay among its regions.
Omnia is a Madrid-based startup with a Spanish-language website, pricing in euros, and published case studies from Spanish companies like TUIO and OkTicket, according to Omnia itself. Promptwatch lists prices in euros and says it complies with the GDPR, the European data-protection regulation, but its website and support are in English and Dutch. We didn’t verify the interface language of any of these apps, nor the taxes involved in paying from Argentina or Spain.
For regional context, Sebastián Galanternik, Sr. SEO at Mercado Libre, the Argentine e-commerce company, discussed AEO, GEO and Search Everywhere Optimization in our interview on Search Everywhere Optimization. And before signing up for a tool, check out what a brand can already see inside ChatGPT without any third party, which we covered in our piece on ChatGPT’s Business Hub.
What these tools can’t tell you
None of the nine companies publishes an independent audit of its measurement accuracy, and the customer case studies they show on their websites also lack independent verification.
SparkToro raised questions that no tool has yet answered publicly: how many times you need to run a prompt to get a statistically solid data point, whether API responses resemble what a user sees on the web, and how many different prompts are needed per topic. Fishkin is asking that vendors of these tools publish that math. Until they do, the visibility percentage is useful for tracking a trend, but the exact number isn’t worth much.
A hands-on test would change this guide: the same 25 prompts over 14 days across Omnia, Peec AI, OtterlyAI and Promptwatch. If all four return similar visibility percentages for the same brands, the decision comes down to price and execution; if they diverge, the open question is which one is actually measuring what your customers see.
Frequently asked questions
What is an AEO tool, and what does it measure?
An AEO (or AI visibility) tool measures how often your brand appears in sample responses from engines like ChatGPT, Google AI Overviews, AI Mode and Perplexity. The result is a visibility percentage relative to competitors, since the order of those lists almost never repeats. Some tools, like Omnia, Promptwatch or AthenaHQ, also recommend, write or publish content to improve that percentage.
Can a brand’s ranking in ChatGPT be measured?
According to a SparkToro study from January 27, 2026, conducted with Gumshoe, which sells a tool in this category, there’s less than a 1-in-100 chance that ChatGPT or Google will return the same list of brands twice, and about a 1-in-1,000 chance that they’ll return it in the same order. Rand Fishkin concludes that ranking is nearly useless, and that visibility percentage across many runs is probably a reasonable metric.
How much does an AI visibility tool cost?
As of November 12, 2026, Promptwatch Explore is free, with 10 prompts and ChatGPT only. Among the paid plans, OtterlyAI Lite costs €29 a month, Omnia starts at €63 a month on annual billing with 25 prompts, Promptwatch Essential and Peec AI Starter cost US$95 a month with 50 prompts, and Semrush charges US$99 a month with 25. Profound doesn’t publish pricing for any of its paid plans.
How many prompts should you track?
OtterlyAI recommends tracking between 50 and 100 prompts per topic or market, and says that in its own study, going from 10 to 100 prompts cut coverage variation by around 73%. OtterlyAI’s Lite plan comes with 16 prompts and Omnia’s entry-level plan with 25, both below that range. Promptwatch Essential comes with 50, at the low end of the recommendation, with a cap of 6,000 responses a month.
