When someone asks an AI assistant about your category, your site is either in the answer or it is not. AI visibility tools exist to measure that: whether assistants like ChatGPT, Google's AI Overviews, Perplexity and Copilot can reach your pages, and how often they cite you next to competitors. It is a different question from search ranking, and the tools that answer it run from free checks to enterprise platforms.
What does an AI visibility tool do?
Most tools do some mix of three jobs:
- Crawler access. Whether AI crawlers such as OAI-SearchBot, Claude-SearchBot and PerplexityBot are allowed to read your pages at all.
- Share of voice. How often AI answers cite you across a set of tracked prompts, next to named competitors.
- Fixes. What to change so you get cited more, from content structure to the rendering and robots issues that keep crawlers out.
Pure rank-trackers do the first two. Broader tools add the third.

Where does each tool fit?
- Profound is the repeated enterprise pick, built for wide engine coverage and deep reporting.
- Peec AI is a credible mid-market option, and one of the few with transparent, published pricing.
- Auditaar goes the widest here. Where the dedicated trackers monitor prompts, Auditaar reads the whole site across six pillars, so a free AI visibility check from a URL leads into a full audit and the recommended fixes, not tracking alone. The free check needs no sign-up, and the Deep Dive is a one-time $499, not a subscription.
- AthenaHQ is strong on query discovery and share-of-voice tracking for mid-sized and smaller teams.
- Otterly AI is the budget-friendly choice for simple AI-mention tracking.
- Semrush AI Visibility Toolkit is an add-on to the Semrush platform, the sensible pick if your team already lives there.
- Writesonic pairs content generation with tracking, for teams that want to write and measure in one place.
How do you choose an AI visibility tool?
- Just want to see where you stand? Start free: a free AI visibility check plus Google Search Console's AI performance reports and Bing Webmaster Tools.
- Need ongoing monitoring across many prompts and engines? A dedicated tracker, sized to your budget.
- Already on an SEO platform? Add Semrush's toolkit before buying a separate product.
- Want the fixes, not just the score? Pick a tool that goes past tracking into recommendations.
How can you measure AI visibility for free?
You do not need a paid tool for a baseline. Run your category prompts ("best [your category] 2026", "[you] vs [competitor]", "what is [category]") in ChatGPT and Perplexity, and log which domains get cited. If you never appear, that is the gap to close. Then run a free AI visibility check to see whether crawlers can even reach your pages, since a site AI cannot read is a site AI cannot cite.
AI visibility tools FAQ
What is the best free AI visibility tool?
There is no single best, but a strong free baseline combines a no-sign-up check of whether AI crawlers can reach your site with Google Search Console's AI performance reports and Bing Webmaster Tools. Auditaar's free AI visibility check covers the first from just a URL.
Is AI visibility the same as SEO?
No. SEO is about ranking in a list of links. AI visibility is about being cited inside an AI-generated answer. A page can rank first and still never be quoted, which is why the tools are separate.
How long does it take to improve AI visibility?
Expect 60 to 90 days. Citations build as AI engines re-crawl the sources they trust, so changes show up gradually rather than overnight.
AI visibility starts with being readable: if an AI crawler cannot reach or parse your pages, no tool can make it cite you. Run a free AI visibility check to see where your site stands, or read what an AI visibility score measures.
