Best AI Visibility Tools (2026): GEO Trackers Compared

AI visibility tools run the questions your buyers ask in assistants like ChatGPT, Gemini, Perplexity and Google AI Overviews, then record whether your brand is mentioned, where it appears and which sources are cited. The best AI visibility tool for you depends on three things: which engines it covers, how it collects answers, and how many prompts you can track for your budget.

Disclosure: we make Citegram, one of the tools in this list. We kept the comparison to facts each vendor publishes on its own website and link to each pricing page so you can check. Prices and features checked on October 9, 2026. Vendors change plans often, so confirm before you buy.

Key takeaways

• AI visibility tools measure mentions, position, cited sources and share of voice across a fixed set of prompts, not traffic or rankings.
• The biggest differences between tools are engine coverage, how answers are collected, prompt limits and price.
• Some vendors say they capture answers from the assistants’ consumer interfaces rather than APIs, because answers can differ between the two.
• Entry prices range from free one-off checks to custom enterprise contracts, and some engines are paid add-ons.
• A two-week pilot on your own prompts tells you more than any comparison table, including this one.

What an AI visibility tool actually measures

Mentions vs citations vs position

A mention is your brand name appearing in the answer. A citation is a link to a source the assistant used, which may or may not be your site. Position is where you appear in a list of recommendations. Asked “best CRM for a 20-person startup”, an assistant might name HubSpot first, Pipedrive second, and cite a review site that ranks both. Those are three different signals.

Share of voice, sources and fan-out queries

Across many prompts, mentions roll up into AI share of voice: how often you appear compared with competitors. Cited sources show which pages shape the answer. Some assistants also run web searches before answering, and those searches, known as query fan-out, show what you need to rank for. Google states that AI Overviews and AI Mode may use this technique in its page on AI features and your website.

How we compared the tools

• Engine coverage (and what costs extra). We list the engines each vendor names on its own site, and flag add-ons. Your buyers may use assistants you aren’t tracking.
• Data method: real app UI vs API sampling. A tool can call a model’s API or ask the question in the consumer app, the way a buyer would. App answers can include web search and citations that an API call may not. We describe a tool’s method only where the vendor states it.
• Prompt limits, refresh frequency, price. Limits decide how much of your market you cover; price decides whether you can run long enough to see a trend. For sizing, see how to choose prompts to track.

Comparison table: the tools at a glance

The tools, one by one

Citegram (our product)

Citegram is a free Chrome extension with a dashboard. It asks your prompts in ChatGPT, Gemini, Perplexity, Claude, DeepSeek, Grok and Google AI Overviews, in background tabs, using the accounts already signed in to your browser. It records mentions, position, cited sources, the web searches ChatGPT ran, and whether an AI Overview appeared. Free covers 1 prompt forever; Pro is $10/month for unlimited prompts.

The trade-off: answers come from your own accounts, so they are real app answers, but memory, location and settings can personalize them. Runs also count toward your own plan usage. Citegram does not track Google AI Mode or Microsoft Copilot.

Profound

Profound says it “captures responses directly from the consumer experience, not API outputs”. Its pricing page lists a free trial on ChatGPT, Gemini and Google AI Overviews with a recommended prompt set, and an Enterprise plan with custom pricing and up to 9 answer engines. It suits larger teams that want daily tracking and enterprise support.

Peec AI

Peec AI’s plans let you choose 3 models among ChatGPT, Google AI Overviews, Google AI Mode, Microsoft Copilot, Gemini and Naver AI. More models, including Perplexity, are paid add-ons, and the Enterprise plan opens the full list. Its documentation says it uses UI scraping. Starter is listed at $95/month (€85 in the EU) for 50 prompts with unlimited users; see the pricing page and our Citegram vs Peec AI comparison.

Otterly.AI

Otterly’s pricing page lists Lite at $29/month for 15 prompts, Standard at $189/month for 100 and Premium at $489/month for 400. Every plan tracks ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Claude, Google AI Mode and Gemini are add-ons priced per plan. A free trial is offered.

Semrush AI Visibility Toolkit

Semrush lists the AI Visibility Toolkit at $99/month, with 25 prompts for Prompt Tracking on the base plan, and names ChatGPT and Google AI Mode as tracked platforms. It fits teams that already work in Semrush.

Ahrefs Brand Radar

Ahrefs Brand Radar offers custom prompts from $50/month, refreshed daily, and an AI Visibility Index from $199/month built on prompts modeled from Ahrefs’ keyword database. Platforms shown include AI Overviews, AI Mode, Perplexity, Copilot, Gemini and ChatGPT, with Claude available. It also covers YouTube and Reddit.

AthenaHQ

AthenaHQ’s pricing page lists a free Essential tier covering ChatGPT, Perplexity, Google AI Overviews, Gemini and Copilot, and Starter at $295/month, which adds engines including Google AI Mode, Claude, Grok, DeepSeek, Meta AI and Mistral. Usage is counted in credits, one credit per AI response.

SE Ranking (SE Visible)

SE Ranking’s standalone SE Visible lists Basic at $99/month for 200 prompts, Core at $189/month and Plus at $355/month, tracking ChatGPT, Gemini, AI Mode, Perplexity and AI Overviews, with a 10-day free trial. SE Ranking also sells AI tracking as an add-on to its SEO platform.

HubSpot AI Search Grader

HubSpot’s AI Search Grader is free and gives a one-off score out of 100 across sentiment, presence, brand recognition, share of voice and market competition. It currently analyzes GPT-5.4 mini, Perplexity and Gemini. It’s a snapshot rather than ongoing tracking of your own prompts.

Which tool fits which team

• Solo founder. Start free: HubSpot’s grader for a snapshot, Citegram’s free plan to track your most important prompt over time.
• SaaS marketing team. You need 20 to 50 prompts, several competitors and trends. Compare tools on the engines your buyers use and the cost per prompt.
• SEO lead. If you already pay for Semrush or Ahrefs, test their AI modules first so AI data sits next to keyword data.
• Agency or enterprise brand. Workspaces, exports and support matter more. Profound, AthenaHQ, Peec AI and Ahrefs list agency or enterprise options.

For first-party citation data, Bing Webmaster Tools added an AI Performance report in public preview, showing how often your pages are cited in Microsoft Copilot and Bing’s AI answers.

How to run a 2-week pilot on your own prompts

1. Pick 10 to 20 prompts your buyers actually ask, mostly unbranded.
2. Shortlist two or three tools that cover the assistants your audience uses.
3. Run the same prompts in each tool for two weeks, without changing wording.
4. Spot-check by hand. Ask a few prompts yourself and compare with what each tool recorded.
5. Compare outputs you’ll act on: mentions, competitors, cited domains, fan-out searches.
6. Decide on cost per useful prompt, not headline features.

3. Run it. Citegram asks the prompt in all 7 assistants in background tabs. First results arrive in about 10 minutes.
4. Read mentions, positions and sources for each assistant, plus ChatGPT’s web searches.
5. Repeat during the pilot and compare share of voice and most cited domains across runs.

FAQ

Are AI visibility tools accurate?

They record the answers they collect, but AI answers vary between runs, accounts and locations. Treat any single result as a sample and judge trends across repeated runs. Tools that state how they collect answers are easier to interpret.

Is there a free AI visibility tool?

Yes. HubSpot’s AI Search Grader gives a free one-off score. Citegram’s free plan tracks 1 prompt across 7 assistants with no time limit. Several paid tools, including Profound, Otterly.AI and SE Visible, offer free trials.

What’s the difference between a GEO tool and an SEO tool?

An SEO tool tracks rankings and traffic for keywords on search results pages. A GEO tool tracks whether AI assistants mention, rank and cite your brand for full prompts. Some SEO suites now include GEO modules, so the line is blurring.

How many prompts should I track?

For many brands, 10 to 30 well-chosen prompts are enough to see patterns. Cover discovery, use-case, comparison and problem-led questions, and add more once you know what you’ll do with the data.

Try it on your own prompts

The quickest way to judge any AI visibility tool is to run your own buyer question through it. Citegram’s free plan tracks 1 prompt across all assistants, forever, and Pro adds unlimited prompts for $10/month. See pricing.
