Why AI visibility matters

A growing share of buying-intent questions never reach Google. They get asked to ChatGPT, Claude, and Gemini, and the answer those assistants give back decides whether your brand is even in the consideration set. If you're not mentioned, you're not on the shortlist — there is no page-two recovery the way there is in classic search.

This free check is the same first-pass diagnostic our paid tier runs against every tracked prompt. It uses the real provider APIs (no scraping, no proxies) and pulls structured citations out of the response so you can see which sources each model trusts. Pass our check and run the full audit to track visibility over time across dozens of prompts.

Frequently asked.

Which models are you actually calling?
OpenAI's gpt-4o-mini for ChatGPT, Anthropic's claude-haiku-4-5 for Claude, and Google's gemini-2.5-flash for Gemini. All three have search/grounding enabled, which is what produces the citation list. We use the same provider clients our paid tier uses — there's no scraping, screenshotting, or unofficial endpoint involved.
What does 'visible' mean here?
Visible means the model either mentioned your brand by name in its prose answer, OR cited a URL on your domain (subdomains count). Mentions and citations measure different things — citations mean the model trusted your content as a source; mentions mean the model knows your brand exists. Both are valuable; getting cited is the harder bar.
Why is the same prompt sometimes free?
We share an LLM response cache across all of our tools. If another visitor ran the same prompt against the same provider in the last 6 hours, you get that answer back instantly with no upstream call charged. You'll see a 'Served from cache' note when this happens.
What can I do with these results?
If a model didn't mention you, you have a content problem on that surface — the model doesn't know enough about you to bring you up. If you were mentioned but not cited, your brand is recognizable but you're not the source the model trusts; the fix is publishing more of the kind of authoritative content that grounded answers reach for. The full rank.ai platform tracks this across dozens of prompts so you can see whether changes you make are working.
How accurate is one check?
One sample is a snapshot, not a trend. LLM answers are stochastic — the same prompt run twice can produce slightly different mentions and citations. The paid tier averages 3 samples per provider per day so you can see the real visibility line over time. Treat this free check as a useful first read, not a final verdict.
Do you store my prompt or my domain?
The result is kept in our cache for 1 hour so you can re-open the page or share the link. Your prompt is normalized and used as a cache key against the LLM cache (so a popular prompt warms the cache for everyone). We don't sell or share inputs. If you provide an email, we'll send you the report and only follow up if we have something genuinely useful for you.
