Semrush shipped an AI visibility toolkit as a paid add-on to its SEO suite. Before adding another subscription, close the technical gates a free check covers — then decide if you still need it.
The toolkit tracks how often your brand appears in AI answers across ChatGPT, Perplexity, Gemini and AI Overviews, with prompt-level reporting and competitor share-of-voice. It's brand monitoring: it measures mentions, it doesn't fix the technical reasons you get none.
Who it's for: Agencies and in-house teams already paying for Semrush, monitoring many brands or clients weekly, who need share-of-voice reporting to justify budget.
A monitoring subscription tells you your share of AI voice; it assumes the pipes work. Most sites we check still have blocked AI crawlers, no schema and no llms.txt — which means zero mentions that no dashboard can explain. The free checker finds those in one run: per-bot crawler access, structured data, citability, scored 0–100 with a fix list.

Budget route before any paid tool: the free AI visibility check, the llms.txt generator, and the fix guides (allow AI crawlers, what AI visibility is). When you do outgrow free, the suites we'd shortlist: Mangools (best value) · Frase (content-to-AEO workflow). Some links are affiliate links.
