Which AI visibility tools let me run a free first audit without a sales demo?

You don't need a sales call to see whether AI platforms describe your brand correctly. Self-serve signup exists in this category, but vendors change their plans often, so the reliable test is to open each tool's signup page and see whether it asks for a card, a call, or nothing.

Two no-demo options are on hand: the free checker on this site runs up to three buyer questions and scores the answers, and 99Visibility's Free plan costs $0 and needs no card. Neither is the only route. Use whichever you start with as a benchmark for the rest.

What matters more than the price tag is what the first audit actually shows you. A free audit is worth your time if it tells you something specific and fixable. It is not worth your time if it hands you one number with no explanation. Our free GEO audit guide walks through the order to check things in: access first, then accuracy.

A good first audit answers four questions in plain terms.

Which engines, scored separately

Google says AI Overviews and AI Mode "may use different models and techniques" and can return different links. ChatGPT, Perplexity, Gemini and Claude differ even more. A single blended score hides an engine that ignores you behind one that names you. Look for one result per platform.

Which questions it asked

The audit should list the exact prompts it ran. Without them, you can't tell whether a result reflects the engine or the prompt choice.

What it got wrong

The strongest finding is a named error: a wrong price, an old product name, a competitor confused with you. "AI doesn't know you" is not a finding.

Whether crawlers can reach you

This is where the evidence is firmest. Check for:

• Per-bot robots.txt rules. OpenAI's crawler page says each setting is independent: GPTBot governs training, OAI-SearchBot governs ChatGPT search.
• Firewall or CDN blocks. A CDN can return 403 to a crawler that robots.txt allows.
• JavaScript-only content. Vercel found ChatGPT and Claude crawlers fetch JavaScript files but don't execute them, so content rendered only in the browser may be invisible to them.
• Snippet controls. noindex, nosnippet, max-snippet:0 and data-nosnippet keep content out of AI answers, and they are often inherited by accident.

An audit that ties each finding to a fix is doing more than tracking. See tracking tools vs fixing tools for that distinction.

Some free audits look thorough but rest on claims the primary sources contradict. Close the tab if you see any of these.

• An "AI rank" or position in Google AI. Google's own report exposes impressions only. There is no position data to check such a number against. Our page on why there's no AI rank to track explains the gap.
• An E-E-A-T score. Google says E-E-A-T "isn't a specific ranking factor". There is no score to measure.
• "Add schema to get cited." Ahrefs' matched test of 1,885 pages found AI Overview citations fell 4.6% after schema was added. Existing markup does no harm, but it is not a lever for AI answers.
• "Publish an llms.txt." Google says Search ignores it, and no engine documents reading it.
• "Allow GPTBot so ChatGPT finds you." GPTBot is for training. ChatGPT search uses OAI-SearchBot.
• Any promised outcome. A critical survey of 45 GEO studies (arXiv, July 2026) found no technique with a stable, cross-platform causal effect on discoverability. A tool that guarantees citations is guessing.

Run the audit, then work through this list before you close the report.

1. Read the prompts. Are they questions a real buyer would ask? If you can't see them, discount the score.
2. Find one engine-specific result. If everything is blended, you can't act on it.
3. Find one wrong fact. Check it against your own site. If your site states it inconsistently, that's your first fix.
4. Check the access section. Does it name which bots were allowed, blocked, or turned away by a firewall? Confirm one result yourself by opening your robots.txt.
5. Check the fixes. Each recommendation should point at a specific page or setting. Generic advice ("improve authority") doesn't count.
6. Note what it costs to repeat. A first audit is a snapshot. Look at what AI visibility tools cost per month if you want the same check run on a schedule.

If two tools pass this list, compare them with the method in how to evaluate GEO tools.

Be plain with yourself about the limits.

• Small samples. Three questions show whether you appear, not how often. Treat a free result as a direction, not a trend.
• Retrieval state. As of October 2026, ChatGPT decides per question whether to search the web, and Claude.ai search is a user toggle. An answer given without search reflects the model's training cutoff, which nobody can change this quarter.
• Personalisation. Logged-in answers can use memory. Results from your own account may not match what a buyer sees.
• Scores across tools. Every vendor's score is its own model. Don't compare one tool's 60 with another's 60.

The next move is simple: fix the access and accuracy problems the audit found, then rerun it. If you're replacing a tool you already pay for, our checklist for switching AI visibility tools covers what to carry over.

Is a free AI visibility audit accurate enough to act on? It is accurate enough to find broken things. A blocked crawler, a firewall returning 403, or a wrong price in an AI answer is a fact you can verify and fix. It is not large enough to measure how often you appear across all buyer questions. Use the free audit to find specific errors and access problems, then decide whether you need repeated checks.

Do I need to give a credit card for a free AI visibility audit? It depends on the vendor, and policies change. 99Visibility's Free plan needs no card, and the free checker on this site needs no signup card either. For other tools, open the signup page and see what it asks for before you enter details. A card requirement isn't a problem in itself, but it should be stated up front.

Why does my free audit score differ between tools? Each tool asks different questions, calls different models, and weights results its own way. Some answers come from live web search and some from the model's training data, and tools rarely control for that the same way. A score is a vendor's model of visibility, not a shared measurement. Compare the specific findings, such as wrong facts and blocked crawlers, rather than the headline numbers.

What should I fix first after a free audit? Fix access first. Check that robots.txt allows the search bots you care about, such as OAI-SearchBot and PerplexityBot, that your CDN or firewall doesn't block them, and that key facts like pricing appear in the HTML before JavaScript runs. Then correct any facts stated inconsistently across your own pages. These are the changes in your control with the clearest documented mechanism.
