The best AI visibility tool depends on what you need to measure and what should happen after you find a gap. Monitoring can show where a brand is missing; the next decision is whether the website needs a new page, an improvement, or no new page. Ahrefs Brand Radar is particularly useful for broad category research. Profound is built for deeper enterprise AEO programs. Semrush fits naturally into an established SEO stack. Peec is strong for focused daily monitoring. OtterlyAI has a low paid entry point. Surfer makes sense when content optimization is the next step. Rankvia is a strong default when you want the same project to use AI visibility and search evidence to decide what the website should do, then generate and publish selected pages through supported destinations. If monitoring is the main job, a dedicated tracker may fit better.
There is no useful universal winner. These products measure different prompt universes, providers, and signals, so two apparently similar AI-visibility percentages may describe different things.
Documentation reviewed 18 October 2026. Rankvia publishes this guide and is included. This is first-party documentation research, not a hands-on benchmark or a ranking. Prices refer to the stated package and billing commitment; local currency and checkout terms can differ.
Choose the responsibility you need after measurement
Ask these questions before comparing provider counts or prices:
- Do you need deeper measurement? Compare the relevant question universe, platforms, language, market, evidence, refresh, export and usable-answer rules. A larger index and a narrowly selected buyer-question sample solve different problems.
- Can your team execute what it learns? Name the person who will validate the observation, choose an action, write or revise the page and obtain approval. If those responsibilities are already covered, a focused monitoring purchase may be sufficient.
- Do you also need decisions and website production? Evaluate how a platform handles existing-page ownership, Create versus Improve, planning, generation and supported publication. Check the actual workflow; “Actions” can mean advice, an agent or executable content work.
- Is the next action outside your website? An independent publisher may own a useful cited page. Your team may need editorial evaluation or outreach rather than another owned article. Rankvia can identify third-party visibility as a possible action; it does not secure placements automatically.
- Is technical work the bottleneck? Verify crawler access, rendering or platform constraints with the right specialist or technical tool. Monitoring a missing citation does not diagnose its cause or automatically repair the site.
- Does the plan you would buy include the needed work? Distinguish trial from ongoing access, per-domain from account pricing, prompt coverage from checks, agent credits from content capacity, and an integration name from supported publishing permissions.
These branches are not fixed product categories. Profound now explicitly markets an AI Marketer that identifies work, drafts content and requests approval, alongside its intelligence tools. That is broader than a monitoring-only description. Source: current Profound platform . Its credits and tracking limits remain plan-specific. Source: Profound plans .
For a concrete CMS or business decision, use the focused guides to WordPress content automation tools, Shopify content-planning tools or SaaS SEO content tools. This page remains the primary owner for choosing AI visibility software.
Best AI visibility tools at a glance
| Tool | Best for | AI coverage | Measurement model | Competitors / SOV | Sources / citations | Entry price |
|---|---|---|---|---|---|---|
| Rankvia | AI visibility that leads to owned-site execution | ChatGPT, Gemini, Google AI Mode | Business-derived buyer questions; actions also use search, SERPs and optional GSC | Yes | Yes | Current catalog below; monthly and annual billing differ |
| Profound | Enterprise AEO programs | Trial: ChatGPT, Gemini, Google AI Overviews; Enterprise: up to 9 engines | Trial: 50 prompts daily for 7 days; tailored Enterprise tracking | Yes | Yes | Brand Trial free; Enterprise custom; agency offer separate |
| Ahrefs Brand Radar | Broad category research | 6 indexed platforms; custom tracking | Search-derived index plus custom prompts | Yes | Yes | $50/mo custom; index price separate |
| Semrush AI Visibility | Existing Semrush teams | ChatGPT, Google AI, Gemini, Perplexity | Database plus custom prompts | Yes | Yes | Check local per-domain price/cadence |
| Peec | Focused daily monitoring and agencies | 3 chosen models on self-serve | Custom prompts | Yes | Yes | Check current checkout price* |
| OtterlyAI | Low-cost dedicated monitoring | 4 included; add-ons vary | Custom prompts | Yes | Yes | $29/mo |

*Peec's public pricing page confirms plan limits and a 15% annual discount but does not reliably expose current dollar amounts. Check the current checkout price before purchasing.
This table is not a leaderboard. Ahrefs tracking a large search-derived prompt index and Rankvia tracking a smaller set of business-specific buyer questions are different measurement products: one prioritizes discovery breadth, the other combines relevant visibility evidence with decisions and eligible work on the existing website.
What happens after a visibility gap is found?
| Tool | Path from insight to action |
|---|---|
| Rankvia | Combines visibility with search and site evidence; can decide Create or Improve, plan and generate selected pages, and publish eligible work to supported WordPress or Shopify destinations |
| Profound | Enterprise intelligence, citation analysis and agents for tailored AEO programs |
| Ahrefs Brand Radar | Category and prompt evidence for a team to use in its wider SEO work |
| Semrush | AI findings alongside its SEO data, audits and reporting |
| Peec | Prioritized actions, agent skills and MCP access; execution depends on the connected setup |
| OtterlyAI | Recommendations, GEO audits and prompt research alongside monitoring |
| Surfer AI Search Analytics | Standalone tracking; Surfer's wider content workflow is separate |
| AthenaHQ | Recommendations and an agent workflow alongside broad model coverage |
| Scrunch | Insights and page audits within a broader site and agent-experience program |
| SE Visible | Primarily monitoring and analysis; deeper execution sits in the wider SE Ranking ecosystem |
These are different execution models, not a claim that other platforms stop at dashboards. Check what is included in the plan you would buy.
What does an AI visibility tool actually measure?
AI visibility tools, also marketed as GEO, AEO, AI-search monitoring, or AI brand-monitoring tools, collect answers from systems such as ChatGPT, Gemini, Google AI, Perplexity, and others. They may report brand mentions, recommendations or position, competitors, Share of Voice, citations, source domains, sentiment, prompt coverage, modeled impressions, and historical change.
Those are not standardized metrics. Ahrefs separately measures mentions, citations, modeled impressions, and AI Share of Voice. Semrush has a proprietary AI Visibility Score alongside other systems. Peec defines Visibility as the percentage of tracked responses containing a brand. Profound separately presents visibility, SOV, Citation Share, sentiment, and position.
Read AI Share of Voice for the competitive metric and AI Mentions vs Citations for the distinction between brand and source presence.
How we compared the tools
This guide uses current first-party product, help, pricing, and methodology pages rather than competing roundup articles for product facts. We considered provider coverage; control over buyer questions; prompt or index breadth; underlying evidence; mentions, recommendations, citations, competitors, and SOV; cadence; geography; SEO integrations; actionability; reporting; pricing; and buyer fit.
We selected ten products spanning custom monitoring, broad indexed research and tools linked to content or site action. Each was evaluated against the same questions: what is measured, how questions and markets are selected, what evidence is available, what work follows a finding, and what the quoted allowance buys. The English factual review supports the Spanish and French versions. Public documentation was reviewed on 18 October 2026; unavailable prices and conflicting packages are qualified below rather than treated as verified. This shortlist is not an exhaustive market inventory, and no accounts, provider scans or performance tests were used for this documentation review.
Provider count alone is a weak buying criterion. Eleven logos are useful only if those systems matter to your customers and the product provides enough evidence to make a decision.

Rankvia
Good fit for: organizations that want AI visibility to lead into decisions and actual website execution, including SaaS and ecommerce sites.
Measure. Rankvia starts with business, offer, audience, positioning, competitor, and existing-website context to select priority buyer questions, then checks ChatGPT, Gemini, and Google AI Mode. It exposes brand appearances, question-level evidence, competitors, competitor SOV, provider-level differences, sources, and recurring scans.
Decide. AI Visibility is one input: Rankvia also weighs search opportunities, current SERP evidence, optional Google Search Console performance data, and existing-page coverage. Before creating another URL, it considers whether an existing page should own the opportunity. The result may be Create, Improve, no additional page, Monitor, Third-party visibility, or Skip.
Execute. For selected owned-site work, Rankvia can prioritize and schedule a dated Content Calendar item, prepare a Page Plan, generate the finished page, plan internal links, and publish eligible content through supported WordPress or Shopify destinations. Review First follows Scheduled → Generated → Review → Publish; opt-in Autopilot follows Scheduled → Generated → Published when the setup supports it. The distinction is how these decisions and production steps form part of Rankvia's default website-growth model, not a claim that other tools cannot generate content or support publishing workflows.
Strengths: business-context setup, buyer-question measurement, source intelligence, recurring scans, page-ownership decisions, and execution of eligible website work. Limitations: only three provider families are advertised, it is not a giant category prompt database, one website is included per plan, and its public enterprise reporting/API/SSO breadth is narrower than enterprise-oriented platforms.
Choose Rankvia when the recurring bottleneck is deciding what deserves action and carrying justified owned-site work toward publication. If you need nine-provider enterprise intelligence, it is not the first shortlist. See the Product overview, Content Calendar, and Page Plans for the wider workflow.

Profound
Good fit for: enterprise brands and sophisticated AEO programs.
Profound's Answer Engine Insights covers monitored prompts and metrics including visibility, SOV, citations, sentiment, and position. Its current public brand pricing offers a free Trial with 50 unique prompts tracked daily for seven days across ChatGPT, Gemini, and Google AI Overviews. Ongoing Enterprise pricing is custom, with tailored prompt tracking and capability for up to nine answer engines. The older published Starter and Growth prices are not listed on its current pricing page.
Its enterprise analytics, citation intelligence, marketing agents and organization controls suit teams needing configurable AEO and marketing operations. The brand trial is time-limited and does not allow custom prompts; ongoing Enterprise monitoring and broader engine coverage are tailored. Brand and agency packages are distinct buying units, so confirm the appropriate offer. Source: current Profound plans .
Ahrefs Brand Radar
Good fit for: broad category research, large-scale prompt discovery, and existing Ahrefs users.
Brand Radar combines two models: an AI Visibility Index built from hundreds of millions of search-derived prompts for immediate category research and Custom Prompts for specific buyer questions, selected providers, locations, and daily, weekly, or monthly cadence. It reports competitor visibility, cited domains/pages, and search-demand-weighted impressions alongside broader Ahrefs SEO data.
Custom-prompt packages are documented at $50 for 2,500 checks, $100 for 7,000, or $250 for 25,000 per month in USD. Existing paid Ahrefs plans also include some checks. An execution consumes checks according to platform, location and cadence; confirm any platform-specific multiplier. Index subscriptions are priced separately, and their current USD prices were not verified in this review. Choose it for category discovery and prompt breadth; modeled impressions are not measured AI audience impressions. Sources: custom-prompt allowances and Brand Radar packages .
Semrush AI Visibility Toolkit
Good fit for: teams already using Semrush and wanting AI visibility beside traditional SEO.
Semrush Base is priced per domain with monthly or annual billing. The reviewed pricing page displayed a localized currency, so a current USD amount is not quoted here. It lists 25 daily custom prompts, one Brand Performance domain, mentions from ChatGPT, Google AI, Gemini and Perplexity, competitor analysis, prompt research and an AI-readiness audit. Broader marketing pages advertise a seven-day trial; confirm whether it applies to the exact standalone package at checkout. Source: AI Visibility pricing .
Its advantage is integration: traditional search data, Site Audit, competitors, and reporting live in one ecosystem. Its limitation is that AI functions are spread across modules and the base custom-prompt limit is modest.
Peec
Good fit for: focused daily monitoring, agencies, and clean competitor/source analysis.
Peec uses a custom prompt library and daily tracking. Its self-service Starter includes 50 prompts, three chosen models, one project, unlimited users, and published metrics for visibility, position, sentiment, SOV, competitors, sources, and prioritized recommendations. Its current public pricing page confirms a 15% annual discount but does not reliably expose the current dollar amounts for Starter, Pro, and Advanced; check checkout before buying.
Peec is a strong shortlist for recurring intelligence. Its public offer extends beyond monitoring to prioritized actions, agent actions, business/project context, skills and MCP access. Self-service plans include three chosen models, with more available as add-ons; Enterprise has broader coverage. Check the selected plan and the work its agents or connected tools can actually perform rather than assuming an MCP connection automatically publishes content. Source: Peec plans and capabilities .
OtterlyAI
Good fit for: inexpensive dedicated monitoring.
Otterly Lite is $29/month for 15 prompts. It includes daily monitoring across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot; Google AI Mode, Gemini, and Claude are paid add-ons. Otterly also offers citation analysis, domain ranking, GEO audits, prompt research, recommendations, and a trial. Source .
It is a clear entry point for teams replacing occasional manual checks. The headline price is not the final price for broad coverage, and Lite's 15 prompts can be restrictive.
Surfer AI Search Analytics
Good fit for: content teams, especially teams already using Surfer.
Surfer's standalone AI Search Analytics tracks ChatGPT, Perplexity, Google AI Mode, Google AI Overviews, and Gemini daily. It includes visibility, SOV, mention gaps, sentiment, CSV exports, share links, and five workspaces. Pricing is $95 for 50 daily prompts, $185 for 100, and $365 for 200; annual effective pricing is lower, and a seven-day trial is advertised.
The standalone subscription is a tracker, not the entire content platform. It becomes a stronger fit when Surfer's wider content workflow is the actual reason for choosing it.
The 50-prompt standalone plan is $95 monthly or $82/month equivalent with annual billing. The advertised seven-day trial continues into a paid subscription unless cancelled. Broader Surfer subscriptions have different tracking allowances; do not substitute a bundled allowance for this standalone package. Source: AI Search Analytics documentation, reviewed 18 October 2026 .
AthenaHQ
Good fit for: teams that need broad provider coverage plus an action or agent layer.
Athena Essential is free. Starter is $295/month for 3,600 credits and eleven advertised models: ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, Claude, Copilot, Grok, DeepSeek, Meta AI, and Mistral. API access and additional credits are paid add-ons. Source .
Athena's breadth, source/competitor intelligence, recommendations, and agent workflow are compelling where broad provider coverage matters. For a team focused on only ChatGPT and Google AI, that premium may buy coverage it does not need.
Scrunch
Good fit for: teams combining AI visibility monitoring with page audits and AI-agent experience work.
Scrunch documents citations, prompt and persona analysis, page audits, agent traffic monitoring and its Agent Experience Platform (AXP). Its retrieved pricing representation lists Starter/Growth packages, while an earlier rendered-page review showed a different Core package. That conflict is unresolved, so this guide does not treat a single price, prompt count or provider list as the current universal offer. Confirm the actual package, billing commitment, included surfaces and separate AXP terms. Source: Scrunch pricing .
It is most relevant when visibility is part of a larger site and agent-experience program, rather than only a tracking need.
SE Visible
Good fit for: high prompt volumes, several projects, and international monitoring.
SE Visible Basic is $99/month for 200 prompts, three projects, and five systems: ChatGPT, Gemini, Google AI Mode, Perplexity, and Google AI Overviews. Core is $189 for 450 prompts and five projects; Plus is $355 for 1,000 prompts and ten projects. The product advertises daily monitoring, seven countries, five languages, and a ten-day trial. Source .
It is an attractive option when monitoring capacity and multi-project support matter more than enterprise workflow depth. The standalone product is primarily for analysis and monitoring; deeper execution sits in the wider SE Ranking ecosystem.
Custom buyer questions versus massive prompt databases
Custom tracking repeatedly checks questions such as “Best payroll software for a 20-person startup?” and “Alternatives to Deel for European employers?” It is useful when buying scenarios are known, the market is niche, relevance matters more than breadth, and a stable baseline matters.
Rankvia, Peec, Otterly, Surfer, Profound, Athena, Scrunch, and SE Visible substantially use this model. Ahrefs and Semrush add broad indexed databases that are useful for category discovery, competitor research, and finding questions you did not know to monitor.
Know whether a metric comes from a broad database or a custom monitored set before comparing it with another tool. The largest prompt database is not automatically the best measurement system for your business.
Which metrics should matter?
- Brand mentions: did the brand appear?
- Explicit recommendations: did the answer affirmatively recommend the product for the buyer need? A neutral mention is different.
- Position: where did the product appear, if the answer provides an ordered list? Position alone does not establish a recommendation.
- Sources and citations: which pages or domains supported the response? Source visibility and brand visibility are separate problems.
- Share of Voice: how does a brand compare with a defined competitor set? Formulas differ materially between vendors.
- Sentiment: how positively or negatively is a brand described? It is inherently more interpretive.
- Modeled impressions: useful for opportunity estimates, but not observed audience reach.
What should you check before buying?
- Which providers actually matter to our customers?
- Can we control exact buyer questions and inspect evidence underneath them?
- Can the product discover questions we have not thought of?
- Can we configure competitors and separate brand mentions from source domains?
- Is the methodology documented and provider-level performance visible?
- What happens after a gap is found?
- What is the real cost at our prompts × providers × markets?
The final question matters more than “starting at.” A $29 plan with model add-ons can cost more for broad coverage, and a check-based plan can scale differently by provider.
Hypothetical capacity example: 50 questions × five providers × 30 daily runs = 7,500 checks before extra markets or reruns. A provider may use different credit or counting rules, so confirm the actual allowance instead of treating questions, responses and checks as interchangeable.

Which AI visibility tool should you choose?
| Buyer situation | Strong starting point | Why |
|---|---|---|
| SaaS or ecommerce site needing owned-site work handled after measurement | Rankvia | AI visibility joins search and site evidence to decide Create, Improve or no new page, then plan, generate and publish eligible pages |
| Low paid entry for focused monitoring | OtterlyAI | $29 entry price, with coverage add-ons to price carefully |
| Enterprise AEO program | Profound | Enterprise analytics, citation tooling, agents, and organizational controls |
| Existing Ahrefs customer | Ahrefs Brand Radar | Existing custom prompts plus an unusually large category index |
| Existing Semrush customer | Semrush | AI visibility alongside existing SEO workflow and data |
| Focused agency or consultant programs | Peec or SE Visible | Daily project monitoring or high prompt/project capacity |
| Content optimization is the main next step | Surfer | Strongest when its wider content workflow matters |
| Broad self-service provider coverage | AthenaHQ | Eleven advertised Starter models |
| Site and agent-experience program | Scrunch | Monitoring combined with site analysis and optimization |
No vendor earns a universal win. Choose the smallest product that can answer the buyer questions, providers, evidence, and action workflow you truly need.
Can you track AI visibility manually?
Yes. Start with 10-20 commercially meaningful buyer questions and record provider, date, brand mention, recommendation, competitors, own-domain citation, and third-party sources. Use the same questions and context repeatedly.
Manual tracking breaks down with frequent reruns, several providers or markets, many questions, competitor history, source analysis, or reporting. Automation is valuable mainly because it preserves a consistent dataset, not because the dashboard looks better.
Frequently asked questions
What is an AI visibility tool?
An AI visibility tool monitors how a brand appears in AI-generated answers. Depending on the product, it may measure mentions, recommendations or position, competitors, Share of Voice, citations, sources, sentiment, and changes over time.
What is the best AI visibility tool?
There is no universal winner. Ahrefs is strong for category discovery, Profound for enterprise AEO, Semrush for integrated SEO teams, Peec for focused daily monitoring, and Otterly for a low paid entry. Rankvia fits organizations that want AI visibility and search evidence to inform page-ownership decisions and eligible website execution.
Which AI visibility tool can also create and publish pages?
Rankvia can turn selected owned-site opportunities into Page Plans, generate finished pages, plan internal links, and publish eligible work through supported WordPress and Shopify workflows. Other products in this guide also offer Actions, content tools, agents, APIs, or external publishing workflows. Compare how each product connects the visibility finding to a website decision and the work that follows.
Which tools track ChatGPT?
All ten products in this comparison support ChatGPT on at least one plan. The meaningful difference is whether ChatGPT is one provider in a custom tracker, part of a precomputed index, or part of an enterprise workflow.
How much do AI visibility tools cost?
Costs depend on the actual package: question coverage, platforms, markets, refresh, reporting, content capacity and agent credits. Compare the same workload and billing commitment. The catalog-derived Rankvia reference above separates monthly charges, the full annual charge and its monthly equivalent; verify other vendors’ current checkout terms using their sources.
Are AI visibility scores comparable between tools?
Not safely without understanding question sets, competitors, providers, locations, counting rules, cadence, and weighting. The same percentage can describe different measurement universes.
Can I track AI visibility for free?
Yes, you can begin with manual observations or an eligible vendor preview. Rankvia’s existing checker requires signup or login, eligibility, website analysis and Business Profile approval before the private AI Visibility preview. It is not an instant anonymous report. No credit card is required for the eligible free preview; paid ongoing monitoring has separate plan limits.
