Can AI even read your site?
Before AI can recommend you, it has to discover, trust, and read your site. This free AI visibility check runs 15 checks against your live domain and shows exactly what to fix.
What this AI visibility checker measures
AI assistants do not rank pages — they retrieve them, read them, and answer in their own words. Three things have to be true before your business can appear in that answer, and the scan tests all three against your live site.
Can AI discover you?
Whether the AI crawlers can reach your pages at all.
robots.txt rules for GPTBot, ClaudeBot, PerplexityBot and Google-Extended, sitemap presence and validity, and whether your key pages are reachable without JavaScript.
Can AI trust you?
The signals models lean on when deciding whether to repeat a claim.
HTTPS, structured data, a clear organisation identity, author and contact information, and whether your pages state who you are and what you sell in plain terms.
Can AI read you?
Whether your content survives the trip into a model's context window.
Server-rendered text versus client-only rendering, heading structure, title and description quality, content depth, and whether your answers appear near the top of the page.
How to read your result
The scan returns a pass, warn or fail against each check, ordered so the blocking problems sit at the top. Work down from there — an AI crawler barred in robots.txt makes every other finding academic, and a site that renders its content only in the browser is invisible to most retrieval regardless of how good the writing is.
Legibility is where AI visibility starts, not where it ends. Once AI can read you, the question becomes whether it actually names you — and who it names instead. That is a measurement over time rather than a single scan: the AI visibility score turns it into one 0–100 number, built from four public weights, comparable week over week.
If you want the fixes as a working checklist rather than a report, the legibility-to-tickets playbook hands the findings to an AI agent that files them in your tracker, and our guide to answer engine optimization covers what to do after the technical blockers are gone.
AI visibility checker FAQ
What is an AI visibility checker?
An AI visibility checker measures whether AI assistants like ChatGPT, Claude, Gemini, Copilot and Perplexity can find, trust and read your website — and whether they mention your brand when someone asks a question you should win. This one runs the legibility half instantly and free: it inspects your live domain against the technical and content signals AI systems rely on, then tells you what is blocking you.
Is the AI visibility check really free?
Yes. The scan runs 15 checks against your live domain with no account, no card and no email required. You paste a domain and read the result. Ongoing monitoring — daily prompts across every platform, competitor tracking and sentiment — is the paid product, but the checker itself is free to run as often as you like.
Do I need to install anything on my site?
No. The checker works from your domain alone — it fetches your pages the way an AI crawler would. Nothing is added to your site and no code or DNS change is needed. The optional traffic tracking in the paid product uses a one-line script, but that is separate from this scan.
How is this different from a normal SEO audit?
An SEO audit asks whether Google can rank your page in a list of ten blue links. This asks whether a language model can retrieve your page, understand it, and repeat what it says in a single answer with no list at all. The overlap is real — both want crawlable, fast, well-structured pages — but AI systems weight things SEO tools ignore: server-rendered text, explicit entity naming, answer-first structure, and whether your robots.txt admits the AI crawlers by name.
Does a good legibility result mean AI will recommend me?
No, and any tool claiming otherwise is overselling. Legibility is the precondition, not the outcome: if AI cannot read you, it certainly will not cite you, but being readable does not make you the answer. Knowing whether you actually get named — and who gets named instead — takes running the questions your buyers ask across the platforms, repeatedly, and watching what comes back.
Which AI platforms does MentionOwl cover?
ChatGPT, Claude, Gemini, Copilot, Perplexity, Google AI Mode. Perplexity and Google AI Mode return web-grounded references we can verify. The ChatGPT, Claude, Gemini and Copilot sources are model simulations — we preserve the full answer and label the source contract honestly rather than presenting an inline URL as proof of retrieval.
How often should I check my AI visibility?
Run the legibility scan whenever you ship a significant site change — a migration, a rebuild, a new framework — since those are what silently break crawler access. Brand mentions are a different rhythm: model answers shift week to week without you touching anything, so they need watching on a schedule rather than checking once.
Readable is the start. Recommended is the goal.
MentionOwl asks 6 AI platforms what they say about your business — every day — and hoots when the answer changes.
