GEO Tools in 2026: Complete Comparison to Choose the Best for Your Brand

The AI visibility tools market has exploded. A year ago, options barely existed; today there are over 30 platforms promising to measure and improve your presence in ChatGPT, Gemini and Perplexity.

The problem: most are designed for the English-speaking market, prices range from $0 to $500/month, and they don't all measure the same things. For an SMB in Spain, Mexico or Colombia, choosing the right tool can be the difference between investing with returns or wasting money.

This comparison analyzes the most relevant options honestly — including Mentio, because we believe transparency builds more trust than hiding. We tell you what each one does well, what it lacks, and who it makes sense for.

The Three Types of GEO Tools That Exist

Before comparing, it's important to understand that not all tools do the same thing. The market divides into three categories, as we explain in our AI SEO guide:

1. Native GEO Tools

Built from scratch to measure visibility in generative AI. They query LLMs, analyze responses and track mentions, position and sentiment. Examples: Mentio, Otterly, Profound, Peec AI, LLM Pulse.

Their advantage: depth of GEO analysis. Their limitation: they don't cover traditional SEO metrics.

2. GEO Modules in SEO Suites

Established SEO platforms that have added AI visibility features. Examples: Semrush AI Toolkit, Ahrefs Brand Radar, SE Ranking AI Tracker, Moz.

Their advantage: integration with SEO data you already use. Their limitation: GEO features tend to be less deep than native tools.

3. Free and Diagnostic Tools

Options for a first analysis without investment. Examples: Mentio Free, HubSpot AI Search Grader, Semrush AI Visibility Checker (free), Mangools AI Grader, Geoptie (free tools).

Their advantage: no cost, perfect for getting started. Their limitation: surface-level analysis, no tracking over time.

Detailed Comparison: The 8 Most Relevant Tools

Mentio (Our Tool — Full Transparency)

What it is: AI visibility platform designed specifically for the Spanish-speaking market. Generates questions in native Spanish (not translations) adapted to the user's industry and market.

What it measures: mentions, position, sentiment, discovered competitors, visibility by LLM (ChatGPT, Claude, Gemini, Grok, Perplexity).

Price: Free plan (1 analysis, 1 LLM). Personal from €29/month. Pro from €79/month. Enterprise from €199/month. See full plans.

Strength: the only tool on the market with questions generated in native Spanish for local markets (Spain, Mexico, Colombia, Argentina, Chile). Separation of organic visibility vs brand knowledge. Visual competitive radar.

Weakness: fewer integrations with external SEO tools than Semrush or Ahrefs. Doesn't offer automated continuous tracking (yet) — analyses run on demand.

Best for: SMBs and agencies in Spain and Latin America that need to understand their AI visibility with native Spanish questions at an affordable price.

Semrush AI Toolkit

What it is: AI visibility module integrated into Semrush's SEO suite, now owned by Adobe.

What it measures: presence in Google AI Overviews, AI visibility score, mentions, prompts that trigger your brand, missed opportunities.

Price: $99/month as an add-on to Semrush subscription (starting at $165/month). Total: ~$265/month minimum.

Strength: full integration with SEO data (you can correlate organic ranking with AI citations). Massive database. Free diagnostic tool (AI Visibility Checker) very useful as a first step.

Weakness: expensive for SMBs. Primarily focused on Google AI Overviews — ChatGPT and Perplexity coverage is secondary. Interface in multiple languages but analysis optimized for the English-speaking market.

Best for: marketing teams with large budgets already using Semrush who want to add the GEO layer without switching tools.

Ahrefs Brand Radar

What it is: AI visibility module within the Ahrefs suite.

What it measures: mentions and citations in AI responses, with a unique distinction between mentions (AI names your brand without a link) and citations (AI includes a link to your site).

Price: from $199/month as an add-on to Ahrefs (starting at $129/month). Total: ~$328/month minimum.

Strength: the mention vs citation distinction is valuable for measuring real traffic impact. Works with millions of real questions based on Google FAQs, not artificial prompts.

Weakness: the most expensive on the list. Only available on mid-tier or higher Ahrefs plans. Less focused on the Spanish-speaking market.

Best for: advanced SEO professionals already using Ahrefs who want to understand AI's impact on their traffic.

Strength: good value for money. The GEO Audit Tool analyzes over 25 technical and content factors. Covers 7 AI platforms. See full Mentio vs Otterly comparison.

Weakness: interface and analysis in English. Doesn't generate questions in native Spanish — you can enter prompts in Spanish but the linguistic analysis is designed for English.

Best for: marketers and SEOs who want solid GEO monitoring at a mid-range price, especially if their market includes English-speaking audiences.

Profound

What it is: enterprise platform for AI citation analysis. One of the most cited data sources in industry reports (they analyzed 680 million citations).

How to Choose? Guide by Profile

If you're an SMB in Spain or Latin America with a limited budget: start with Mentio Free for your first diagnostic. If you need regular analyses, the Personal plan (€29/month) covers 5 monthly analyses with native Spanish questions. It's the most affordable option and the only one designed specifically for your market.

If you already use Semrush and have budget: the AI Toolkit is a natural extension. You don't need another tool if you're only interested in Google AI Overviews. But if you want to cover ChatGPT, Perplexity and Claude too, you'll need to supplement it.

If you already use Ahrefs and care about real traffic: Brand Radar is the only tool that distinguishes between mentions and citations with links. Ideal if you want to measure direct impact on visits.

If you're an agency managing multiple brands: Otterly or Mentio Pro offer the best price-to-functionality ratio for managing multiple clients. Mentio if your clients are Spanish-speaking; Otterly if they're international.

If you're enterprise with a large budget: Profound is the most complete and deep option. If you need security certifications (SOC 2, HIPAA), it's the only option.

What No Tool Can Replace

Any GEO tool gives you data. But data without strategy is useless. As we explain in our guide on how to measure AI visibility, what matters is what you do with the information: if your mention rate is low, you need more digital presence. If your position is poor, you need more authority. If sentiment is negative, you need to review your online reputation.

The tool is the thermometer. The strategy is the treatment.

Start by Measuring

You don't need the perfect tool to take the first step. You need to know where you stand now. Any of the free options — Mentio Free, Semrush AI Checker or HubSpot AI Grader — will give you a first snapshot in minutes.

If your market is Spain or Latin America, Mentio is the only one that generates questions in native Spanish for your specific industry and country. Not translations: questions your real customers would ask ChatGPT.
