The best AI search visibility tools to check if ChatGPT cites your brand (2026)

When a potential customer asks ChatGPT, Perplexity, or Google’s AI Overviews for the best option in your category, the AI returns a single answer. Your brand is either named in it or it is not, and unlike a search ranking, there is no page two to climb to. The tools below exist to tell you which side of that line you are on, and what to do about it.

The best AI search visibility tools show whether AI engines like ChatGPT, Perplexity, and Google AI Overviews mention your brand. Free checkers such as HubSpot AI Search Grader and the Essentras AI Visibility Score give an instant page-level score, while paid platforms like Otterly.ai, Peec AI, and Profound monitor your mentions and citations across engines over time.

They fall into two groups: free checkers that score a single page instantly, and paid platforms that track your brand across engines on a schedule. Start with the first to audit, move to the second to monitor.

Why AI search visibility needs its own tools

Traditional SEO tools were built for a list of ten blue links. They cannot see inside an AI answer, which names a few brands, cites a few sources, and ignores the rest. That blind spot is growing fast: roughly two-thirds of Google searches now end without a click as AI answers absorb the query, and brands cited inside AI Overviews have been found to earn markedly more clicks than those left out. Measuring your presence in those answers is now a separate discipline from rank tracking, which is why this category of tools appeared.

Free tools to check your AI visibility instantly

If you just want to know where a page stands right now, start here. Both are free and take under a minute.

HubSpot AI Search Grader

A free one-shot scan that shows how ChatGPT, Perplexity, and Gemini represent your brand and topics. It is a quick way to get a baseline read on mentions and sentiment without committing to a subscription. Access: free with a HubSpot account.

Best for: a fast, no-cost first look at how AI engines see you.

Essentras AI Visibility Score

Rather than tracking mentions, this tool audits a single page for how cite-worthy it is. You paste a URL and it scores the page across seven dimensions that AI assistants weigh when choosing citations, including schema markup, content depth, authority signals, factual density, citeable claims, freshness, and AI-readable structure, then tells you specifically what to fix. The analysis is run by a language model reading your actual page, so it reflects what an AI engine would find rather than a generic checklist. Access: free. You can try the Essentras AI Visibility Score on any URL.

Best for: auditing and fixing a specific page before you publish or optimise it.

Ongoing AI visibility monitoring platforms

Once you know a page’s baseline, these platforms track your brand across engines over time, so you see trends and competitor movement rather than a single snapshot.

Otterly.ai

An affordable, widely used monitor that tracks brand mentions and citations across ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot, with Gemini and AI Mode available as add-ons.

Best for: teams that want a straightforward ongoing tracker without enterprise pricing.

Peec AI

Daily tracking across ChatGPT, Perplexity, and Google AI Overviews, with an emphasis on prioritised actions that tell you which content to create and which sources to target, not just a dashboard.

Best for: SaaS and agency teams that want next steps attached to the data.

Profound

An enterprise-grade platform aimed at larger teams that need deep coverage and analytics across the major answer engines.

Best for: enterprises with the budget and scale to match.

Frase

Pairs AI-engine monitoring with a content workflow, so research, drafting, and GEO scoring live in the same place as the measurement, which keeps finding and fixing citation gaps in one tool.

Best for: content teams that want measurement and production together.

Semrush AI Toolkit

If you already use Semrush, its AI toolkit tracks mentions and citations across the major engines and is built for multi-brand reporting with exec-ready exports.

Best for: agencies and multi-brand marketers who want it inside a familiar suite.

How to choose the right tool

Match the tool to the job. If you need a quick, free audit of whether a page is even cite-worthy, start with a free checker like HubSpot’s grader or essentras.com. If you need to watch your brand’s presence over weeks and catch a competitor overtaking you, move to an ongoing monitor like Otterly.ai or Peec AI. Larger teams and agencies will lean toward Profound, Frase, or the Semrush toolkit for depth and reporting. The sensible sequence is to audit first, fix what the audit flags, then commit to a monitor once your pages are actually built to be cited.

Frequently asked questions

What is an AI visibility tool?

Software that shows whether and how AI answer engines like ChatGPT, Perplexity, and Google AI Overviews mention or cite your brand, either as a one-off page score or as ongoing monitoring over time.

Are there free AI visibility tools?

Yes. HubSpot’s AI Search Grader and the Essentras AI Visibility Score both give a free instant read, which is enough to get a baseline before paying for a monitoring platform.

How is AI visibility different from SEO rank tracking?

Rank tracking measures your position in a list of links. AI visibility measures whether you appear inside the AI-generated answer itself, which is a different and often invisible surface that traditional tools do not capture.

How do I improve my AI citation rate?

Make each page easy for a model to parse and trust, with clear structure, specific claims, schema, and freshness, and earn mentions on credible third-party sites the engines already reference. Audit a page first, then fix the gaps it reveals.
