Technical scan versus brand-visibility platform
AI Crawl Score and the Semrush AI Visibility Toolkit are sometimes shortlisted together because both mention “AI search,” but they answer different questions: one checks whether a site is technically fetchable and well-marked-up, the other tracks whether a brand is mentioned inside AI-generated answers.
What Semrush AI Visibility Toolkit does
According to Semrush’s own feature documentation, the toolkit includes a Visibility Overview that assesses a brand’s presence across LLM answer engines and Google’s AI Overviews, a Brand Performance module tracking share of voice and sentiment, Prompt Research that surfaces the prompts people ask AI tools in a given topic, and a Domain Overview that benchmarks mentions and citations alongside classic organic metrics. It also includes an AI Search Site Audit component aimed at technical issues that could block AI bots. This is a subscription product inside the larger Semrush suite, built around recurring brand and prompt tracking rather than a single-scan technical check.
What AI Crawl Score does
AI Crawl Score does not track brand mentions, prompt volume, or sentiment inside AI answers at all. Its free readiness checker performs a bounded raw-fetch scan of up to five pages, reporting robots.txt directives by crawler identity, sitemap presence, JSON-LD structured data, and basic delivery problems like redirects or blocking responses. It is a diagnostic for “can a crawler reach and parse this,” not a monitor for “is my brand showing up in ChatGPT answers.”
Side by side
| Question | AI Crawl Score | Semrush AI Visibility Toolkit |
|---|---|---|
| Tracks brand mentions in AI answers | No | Yes |
| Checks robots/sitemap/structured data | Yes | Partial, via its site-audit module |
| Prompt-level research | No | Yes |
| Ongoing monitoring | No, point-in-time scan | Yes, recurring |
| Cost | Free | Paid Semrush subscription |
| Scope | Single site, bounded sample | Brand across the open AI-answer surface |
Which one fits your situation
If the need is “did my last deploy break robots.txt or remove a canonical tag,” a free AI Crawl Score scan answers that in under a minute with no subscription. If the need is “how often does ChatGPT mention our brand compared to competitors, and which prompts trigger that,” that is squarely a brand-visibility tracking job the Semrush toolkit is built for, and AI Crawl Score makes no attempt to measure it. Google’s own AI-features guidance treats technical fundamentals and content quality as foundational to any AI-era visibility, so the two categories are complementary rather than substitutes: a technically broken page will not earn citations no matter how well a brand-tracking tool measures the gap.

Frequently asked questions
Can AI Crawl Score tell me if ChatGPT mentions my brand?
No. It does not query AI answer engines or track brand mentions; it inspects what a crawler would fetch from your own site.
Is the Semrush toolkit a replacement for a technical crawl audit?
Its AI Search Site Audit component covers some technical issues, but a dedicated raw-fetch check like the AI Crawl Score scanner is narrower and free to run on demand.
