Free GEO diagnostic or paid audit: which do you need?
By The Venoh team · Last updated September 25, 2026
Free AI visibility checks are genuinely useful, and for some companies they are enough. A paid diagnostic earns its price only when you need to know why you are missing, who is winning instead, and exactly what to publish. Here is how to tell which situation you are in.
What the free options give you
- Jasper GEO Diagnostic is free with no account. According to Jasper, it tests ChatGPT, Claude and Gemini and returns scores for brand presence, citation rate and sentiment, with per-model breakdowns, competitor analysis and page-level recommendations.
- GeoAnalyzer gives a free 0-100 GEO/AEO score, and a 15-25 page PDF report for $19.
If you only want to know whether AI engines mention you at all, start with one of these. It costs nothing and answers that question.
What a paid diagnostic adds
| Question you need answered | Typical free score | Venoh diagnostic ($400) |
|---|---|---|
| Do AI engines mention us? | Yes | Yes: around 30 buyer questions, each engine asked twice |
| Which engines were tested? | Usually a fixed set | ChatGPT, Perplexity, Gemini and Claude, named in the report with the date |
| Were the questions unbiased? | Varies | Category questions never name you; brand questions are asked separately |
| Who shows up instead of us, and how often? | Sometimes | Competitor share of voice, per engine and per question |
| Which pages do the engines rely on? | Rarely | The most-cited URLs in your category, marked as competitor, review/list site or publisher |
| Is what AI says about us correct? | Sentiment only, in some tools | Each factual statement checked against your own site; contradictions flagged with the quote |
| Can AI crawlers read our site? | Rarely | robots.txt checked for 13 AI crawlers, plus llms.txt, sitemap, FAQ and structured data |
| What exactly should we publish? | General recommendations | FAQ answers drafted from your own pages, ready-to-paste structured data, comparison page outlines |
| Is every number real? | Depends on the tool | Counted by software from the raw answers; the written findings are checked by a separate model before delivery |
When to pay, and when not to
- Don't pay if a free score shows you are already cited often for your key questions and nothing looks wrong.
- Pay if you are missing from answers to questions your buyers ask, you don't know who is winning them, or AI engines describe your company incorrectly.
- Pay if you need something your team can act on this week: specific pages to write, content drafted from your own facts, and markup to paste.
Either way, treat any AI visibility result as a dated snapshot. Answers change with wording and over time, and nobody can guarantee what an engine will say.
Frequently asked questions
Is there a free GEO diagnostic?
Yes. Jasper offers a free GEO Diagnostic with no account required, testing ChatGPT, Claude and Gemini, and GeoAnalyzer offers a free 0-100 score. They are a good first check of whether AI engines mention you.
