Semrush AI Toolkit watches how your brand appears in AI answers and reports it. Reflexa puts an agent on the site and changes the site. Different jobs: one tells you where you stand, the other does the work that moves it. Below, what each does in its own words, side by side, and when each is the better choice.
From Semrush AI Toolkit's own site, read on 9 October 2026: Semrush AI Toolkit is the AI visibility add-on inside Semrush: a share-of-voice view of how often a brand appears across the engines it queries, beside the SEO data a Semrush subscriber already tracks. Engines it names: ChatGPT, Google AI Overviews, Gemini and Perplexity — Claude is not in its list; confirm the current list on Semrush's page. Pricing: sold as an add-on to a Semrush subscription; the current price is on Semrush's pricing page. https://www.semrush.com/
Reflexa puts an agent on the website — one middleware file on a coded site, a plugin on WordPress — that reads the pages the way Google and the AI engines read them (23 checks), applies the fixes the owner approves from inside the site, writes a page's title, description, opening or FAQ for approval, counts every AI visit page by page, and answers questions about the site. Every change is applied from inside the site and is reversible; nothing is applied without approval. The page check is free in a free account; Starter $49/month, Growth $149/month (five times the usage); Free keeps one site, paid plans do not count sites.

| What it is | is the AI visibility add-on inside Semrush: a share-of-voice view of how often a brand appears across the engines it queries, beside the SEO data a Semrush subscriber already tracks | puts an agent on the website — one middleware file on a coded site, a plugin on WordPress — that reads the pages the way Google and the AI engines read them (23 checks), applies the fixes the owner approves from inside the site, writes a page's title, description, opening or FAQ for approval, counts every AI visit page by page, and answers questions about the site |
| Engines | ChatGPT, Google AI Overviews, Gemini and Perplexity — Claude is not in its list; confirm the current list on Semrush's page | the checks are engine-agnostic — they test what every fetcher needs (robots.txt per crawler, raw HTML, structured data); AI traffic counts the crawlers of OpenAI, Anthropic, Perplexity and Google by verified user-agent and IP |
| On the site | no — a Semrush report | yes — the agent runs on the site and is bound to it by its token and a domain proof |
| Applies fixes | no — trend lines and recommendations | yes — four switches applied from inside (AI crawlers in robots.txt, Organization JSON-LD, sitemap, /llms.txt) and page text written and published on approval, every change reversible |
| AI traffic | no on-site counting | yes — every AI request the site receives, split into pages opened to answer someone, pages crawled to learn, and people who clicked through |
| Pricing | sold as an add-on to a Semrush subscription; the current price is on Semrush's pricing page | the page check is free in a free account; Starter $49/month, Growth $149/month (five times the usage); Free keeps one site, paid plans do not count sites |
A Semrush subscriber who wants an AI share-of-voice trend line next to the keyword and backlink data already there.
A company that wants the site itself made readable and recommendable — the crawler access, the structured data, the answer-first text — done on the site rather than listed in a report, with every AI visit counted from inside and a price that starts at free. Many teams run a visibility report beside it; the two do not overlap.
