AI Visibility Tools Compared 2026 — A Complete Guide to GEO·AEO Diagnostic SaaS

Ask ChatGPT to "recommend an AI visibility tool" and you get a different list every time. Through 2026 this category has grown fast enough that a new tool seems to appear almost every month — which makes "what should I actually pick" the hard part.

This article compares 13 tools that measure brand exposure inside AI answers (ChatGPT, Gemini, Perplexity, and others), grouped into three families: dedicated GEO/AEO SaaS, AI extensions of existing SEO tools, and Korea-focused platforms. It puts pricing, supported engines, and recommended users into one table, and offers criteria for choosing by company size and language environment.

What is an AI visibility tool?

An AI visibility tool analyzes how often, and in what context, a generative AI — ChatGPT, Gemini, Perplexity, and the like — mentions or cites a specific brand or website when answering a user's question. (For a detailed category definition, see the AI Search Visibility Tool — Glossary.)

Where a traditional SEO tool asks "what rank am I on Google," an AI visibility tool asks "do we appear inside the AI's answer." You can rank #1 on Google and still never show up in a ChatGPT answer — in which case you are effectively invisible to AI users. Closing that gap is the job of GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization), and an AI visibility tool is the dashboard that measures the result.

Three families of tools

Asking several AI models the same questions, the market's tools sort into roughly three types.

1. Dedicated GEO/AEO SaaS — newer tools built from the start to measure AI answer visibility. Profound, Otterly.AI, Peec AI, KIME, and others.
2. AI extensions of existing SEO tools — large SEO platforms such as Semrush and Ahrefs that already hold search data and have bolted on AI visibility features.
3. Korea-focused platforms — tools tuned to Korean-language answer patterns, the Naver AI environment, and the local marketing context. RanketAI, Bluedot Intelligence, ChainShift, NNT Insights, FrostAI, and others.

① Dedicated GEO/AEO SaaS (global)

These newer platforms were designed from the start to measure AI answer visibility. They are strong at tracking many AI models and comparing competitors, but most have English-only interfaces and weak support for Korean and the Naver environment.

Profound

The enterprise tool most often named in the AI search visibility market. It tracks roughly ten platforms — ChatGPT, Perplexity, Gemini, Claude, and more — and offers brand mention rates, citation sources, sentiment analysis, and compliance features such as SOC 2. In February 2026 it raised $96 million, underscoring the market's attention.

However, every plan is sales-led with no free trial, and even Lite starts around $499/month. Data typically takes one to three weeks to accumulate, which is a burden for teams that want to start small and fast. It suits large brands such as Fortune 500 companies.

Otterly.AI

A low-barrier tool whose Lite plan starts around $29/month. It checks answers daily across six platforms — ChatGPT, Google AI Overviews, Perplexity, Bing AI, Google AI Mode, and Gemini — aggregating mention frequency, sentiment, and citation links. The 14-day free trial requires no credit card, so it is easy to test. Good for individuals and small teams tracking AI exposure lightly.

Peec AI

A dedicated GEO/AEO tool whose strengths are a clean UI and fast onboarding. Its starting plan is around $89/month, and every plan includes a 7-day free trial and unlimited seats. Its Actions feature (in beta) turns visibility data into a prioritized GEO to-do list, bridging measurement and execution. A fit for marketing teams and agencies managing multiple accounts.

KIME

What stands out is that KIME tracks ten AI models — ChatGPT, Perplexity, Gemini, Claude, and more — regardless of plan tier. Lite starts at €149/month, and it provides an Action Center to drive optimization work and an AI Perception module that analyzes how AI describes your brand. It fits startups, e-commerce brands, and agencies that want broad coverage across AI models.

② AI extensions of existing SEO tools

These are AI visibility features added by large SEO platforms that already hold vast search data. They are efficient for teams that want to manage AI data inside their existing SEO workflow rather than adopting a separate tool.

Semrush AI Visibility Toolkit

An AI-search feature from Semrush, the global #1 SEO platform. Backed by a large database of AI search prompts, it reverse-engineers which questions surface your own and competitor domains, and visualizes AI share of voice (SOV). Its strength is direct integration with existing keyword research data.

Ahrefs Brand Radar

A feature from SEO heavyweight Ahrefs that uses backlink and entity data to track which sites AI answers cite. Brand entity analysis and integration with existing SEO data are its strengths, making it a natural extension for teams already on Ahrefs.

③ Korea-focused platforms

These tools are tuned to Korean-language answer patterns, the Naver AI environment, and the local marketing context — filling areas global tools cannot cover.

RanketAI

RanketAI is a GEO & AEO measurement tool for Korean-language AI search that measures brand exposure in AI answers and identifies the questions where the brand does not yet appear. Rather than stopping at measurement, it connects live exposure measurement → brand recommendation opportunities → competitor comparison as one flow, and measured results can be read against a public benchmark that is republished every month. Pricing is published openly across five tiers starting at ₩0.

Four features pass each stage's output into the next as input.

• Page Structure Diagnostics — enter a single URL and it analyzes schema (Schema.org), meta tags, heading structure, AI crawler accessibility, and more to produce a GEO & AEO grade and score. It is free to use without logging in.
• AI Brand Visibility Analysis — it queries ChatGPT, Perplexity, and Gemini with varied prompt combinations to measure whether your brand actually appears in answers, and provides an action guide for improving exposure.
• Brand Recommendation Opportunities — it isolates the questions where the brand did not appear, maps the entry points still missing and the category ownership position, and ranks which gaps to close first. This stage looks for the absences, not the appearances.
• Competitor Comparison — it compares AI exposure share (SOV) against competitor domains to settle improvement priorities.

It suits teams that must decide what to build next, not only confirm whether they appear, and marketers working mainly with Korean-language content. If you want to understand why your brand is missing from AI answers, 13 Questions When Your Brand Is Missing from AI Answers is worth reading alongside this guide.

Bluedot Intelligence

A Korean analysis-and-execution platform specialized in AI search optimization for enterprise brands. It is built on three axes — brand visibility and sentiment analysis, AI search citation-source analysis, and customer search-intent analysis — and tracks the gap between visibility and citation rate as a metric. It bundles an integrated service spanning AI channel launch, prompt setup, and schema optimization, so it fits Korean enterprises that need in-depth analysis together with execution support.

ChainShift

A Korea-based AEO platform that analyzes answers from 7 LLMs and turns AI search visibility into measurable KPIs. It supports citation-source tracking, competitive benchmarking, improvement-item generation, and before/after campaign measurement. It suits B2C and highly competitive-industry brands that need to manage brand perception inside AI answers.

NNT Insights

A Korean tool that consolidates traditional and AI search performance into a single dashboard. Alongside SEO data from Google and Naver, it monitors citations in Google AI Overview and Naver AI Briefing, and tracks citations across generative AI such as ChatGPT, Gemini, Perplexity, Claude, and Copilot. It notably accumulates history beyond Naver's 90-day data limit, giving it an edge for Korean B2B marketers and agencies who must also watch the Naver AI environment.

TeamHAI (added 2026-07)

A GEO platform run by the marketing agency Inus Community, bundling diagnosis and measurement with a content studio and managed operations in a "diagnose→content→operate" package. It states tracking of four engines — ChatGPT, Perplexity, Gemini, and Claude (per vendor) — and its BASIC plan at KRW 99,000/month is among the lower published entry prices for Korean tools. Its free diagnostic runs through a consultation meeting, a different entry path from instant self-serve diagnostics. It fits Korean companies that weight execution services over standalone measurement.

Onthe AI (added 2026-07)

A hybrid that pairs an automation platform — customer question analysis→content generation→distribution→monitoring — with expert onboarding. It supports ChatGPT, Gemini, Perplexity, and Claude, and offers a Pro plan at KRW 500,000/month with a card-free 7-day trial. It is centered on content automation rather than standalone measurement, so it fits Korean companies that want content production automated in one flow.

FrostAI (added 2026-08)

A Korean AEO platform run by RiseMoment Inc. that pairs visibility measurement with AI-agent-driven strategy and content execution. It measures brand visibility scores, competitor rankings, and answer share across ChatGPT, Google AI Overview, and Perplexity (Claude and Gemini are listed as upcoming), and provides prompt-strategy recommendations plus automated content generation for AI search. Published pricing starts at Silver KRW 79,000/month with a card-free 7-day trial. Like TeamHAI and Onthe AI it leans toward execution bundling rather than standalone measurement, so it fits Korean companies that want an agent to carry measurement results into content production.

Which tool should you choose?

Tools are separated less by superiority than by segment. Criteria by situation:

• For large enterprises and regulated industries where global references matter → Profound. Choose it when you can absorb the cost and onboarding time.
• To track many AI models broadly and manage multiple accounts → KIME or Peec AI. Both are agency-friendly.
• For an individual or small team starting lightly → Otterly.AI. Its low starting price and free trial are the draw.
• If you already use Semrush or Ahrefs → turning on that platform's AI extension first is the most efficient choice for cost and workflow.
• If Korean-language content or the Naver AI environment matters → a Korea-focused tool. Among them, NNT Insights if you must also watch Naver AI Briefing.
• If you need to watch how your brand is currently mentioned, day by day → Bluedot Intelligence. It tracks mention frequency, sentiment, and citation sources as indicators, and bundles execution support.
• If you want to find the questions where you do not yet appear and rank them → RanketAI. It carries measurement through to missing entry points, category ownership position, and standing against competitors, and its monthly public benchmark lets you read results against an external baseline.

No matter which tool you use, without the fundamentals — structured data, a clear heading hierarchy, and content that answers questions directly — AI cannot pull your information. But measurement alone does not decide the next action. When choosing, also check whether it carries you from "do we appear" to "which questions are we absent from", and whether there is a public baseline to read your numbers against.

Frequently asked questions (FAQ)

In summary

The AI visibility tool market is expanding fast in 2026, and a standard has not yet settled. So rather than chasing "the best tool," it matters more to first decide the segment that fits your language environment, measurement purpose, and budget.

If your content is mainly in Korean, the fastest way to set execution priorities is to measure your brand's exposure inside AI answers and then get a list of the questions where you still do not appear. Measure your brand's AI exposure with RanketAI.
