AI Readability Check
FREECan AI even read your site? GPTBot, ClaudeBot and PerplexityBot don't run JavaScript — many modern sites show them an empty shell. See side by side what a human sees and what the AI crawlers see: readable text, robots.txt, llms.txt and structured data. Answer in 10 seconds.
AI Mention Checker
FREEAsk ChatGPT, Perplexity or Gemini something a customer would ask — paste the answer and instantly see whether your business is mentioned, in what tone, how high you rank, and which sources the AI cites.
GEO Prompt Generator
FREEEnter your topic and get a list of the prompts your customers actually ask ChatGPT, Perplexity and Gemini. Prompts are the keywords of GEO — know the questions, check whether you're mentioned, and create content that makes you the answer.
Content Brief Generator
FREEEnter a topic and get a data-driven content brief — title suggestions, a ready outline with H2 headings and key points, important keywords and GEO recommendations. All based on what already ranks, so you write content ChatGPT and Perplexity cite.
Nordic Citation Checker
FREEIs your business listed in krak.dk, dineo.dk, gulesider.no, hitta.se, eniro.se and Trustpilot? Local citations are an important trust signal for AI search — and no international GEO tool checks the Nordic directories. We do.

What a GEO tool does
Three jobs: measure whether AI can use your site, diagnose what blocks it, and tell you what to fix first.
Measure. AI assistants answer with the sources they can find, read and trust. A GEO tool checks the signals that decide this: can AI crawlers access your site at all (robots.txt), is your content readable without JavaScript, do you publish an llms.txt, is your structured data in place, and do your pages answer questions directly? The free GEO test scores 15 such dimensions in 60 seconds.
Diagnose. The most common failures are invisible from a browser. When we scanned 465 search-visible business websites in July 2026, 89% had no llms.txt — and a meaningful share served AI crawlers little or no readable text at all, because their content only exists after JavaScript runs. Your site can look perfect to you and be an empty shell to GPTBot. That is exactly what the AI Readability Check makes visible.
Fix — with honest expectations. Technical GEO work is measurably worth doing: research from Princeton and Georgia Tech (Aggarwal et al., KDD '24) found up to a 40% visibility lift in generative engines. But our own data also shows its limit. Across 576 AI answers, businesses that AI cited as a source had clearly higher technical scores (p=0.000) — while technical score made no difference to who AI recommended (p=0.988). Technical work gets your pages used as a source; being recommended also depends on reputation, sector and demand. Any tool promising you customers from technical fixes alone is promising too much.
About the numbers
Data collected by Geoa in July 2026: 465 search-visible business websites in Denmark across three sectors, and 576 questions put to ChatGPT, Gemini, Claude and Perplexity with web search enabled. None of the businesses are Geoa customers. Full method in the analysis.
When free is enough
The free tools give you a snapshot and a to-do list. A paid platform does the watching and fixing for you.
| Free GEO tools | Paid GEO platform | |
|---|---|---|
| GEO score | One-off snapshot, run it whenever you like | Re-scored on a schedule, with history over time |
| AI mentions | Manual check, one AI answer at a time | Monitored across ChatGPT, Claude, Gemini and Perplexity |
| llms.txt | Generated once — you upload and maintain it | Kept up to date through the WordPress or Shopify integration |
| Fixes | A checklist tells you what to do | Auto-Fix applies the technical fixes for you |
| Competitors | Public benchmark of 40 Nordic companies | Your own competitors, tracked continuously |
| Price | Free — no login, no card | From €39/month, 14-day free trial, no card |
An honest rule of thumb: if you want to know where you stand and are happy to do the work yourself, the free tools cover you. The platform is for when you want it measured, monitored and fixed without thinking about it.
Questions & answers
What is a GEO tool?
A GEO tool measures and improves your visibility in generative AI answers — ChatGPT, Claude, Gemini, Perplexity and Google's AI Overviews. Where an SEO tool tracks your Google rankings, a GEO tool checks whether AI systems can find, read and cite your website: crawler access, llms.txt, structured data, readable content and brand signals. GEO stands for Generative Engine Optimization.
Are these GEO tools really free?
Yes. Every tool on this page is free to use — no login, no credit card, no trial countdown. They are how we show what Geoa measures. The paid product is the platform on top: continuous monitoring, weekly scoring and automated fixes, from €39 per month with a 14-day free trial, no card required.
Which free GEO tool should I start with?
Start with the AI Visibility Checker. It takes 60 seconds, scores your site across 15 technical dimensions and hands you three concrete fixes. Then run the AI Readability Check — if AI crawlers cannot read your site, nothing else matters until that is fixed.
Do free GEO tools work for any website?
The technical checks work on any public website, in any language — they read your site the way AI crawlers do. One exception: the Nordic Citation Checker covers Nordic business directories (krak.dk, gulesider.no, hitta.se, eniro.se and more), so it is most useful if you operate in Denmark, Norway or Sweden.
What is the difference between free GEO tools and a paid GEO platform?
Free tools give you a snapshot: where you stand right now, and what to fix — you do the fixing yourself. A paid platform does the work continuously: it re-scores your site on a schedule, tracks whether AI actually mentions you over time, monitors competitors and applies technical fixes automatically. If you just want to know where you stand, the free tools are enough.
Which AI engines do the tools cover?
Geoa measures visibility in ChatGPT, Claude, Gemini, Perplexity and Google's AI Overviews. The technical checks apply across engines, because the underlying signals — crawler access, structure, citability — are largely the same.
Does GEO matter if I already do SEO?
Yes — and your SEO work is not wasted. A technically sound, crawlable site is the shared foundation. But GEO optimises for a different outcome: being cited inside the AI answer rather than ranking in a list of links. Research from Princeton and Georgia Tech (KDD '24) measured up to a 40% visibility lift in generative engines from GEO methods — work that classic SEO does not cover.
