Semrush AI Toolkit is the AI visibility extension from Semrush, one of the most recognized names in SEO since 2008. Semrush launched their AI Toolkit in late 2025 to help brands track visibility across ChatGPT, Google AI Mode, Perplexity, and Gemini.
If you're evaluating AI visibility tools, here's a detailed breakdown of how Semrush AI Toolkit works, what Semrush AI Toolkit costs in 2026, and how Semrush compares to Mentionable's full AI visibility stack.
How does Semrush AI Toolkit track AI visibility?
Semrush AI Toolkit is built around six core features that extend their existing SEO platform into AI search monitoring.
Visibility Overview provides a benchmark score for how visible your brand is across AI platforms. It works like Domain Authority, but calculated from AI search responses instead of backlinks.
Prompt Research is Semrush's version of keyword research for AI. You search their database for prompts relevant to your industry, see estimated "AI volume," difficulty scores, and which brands are getting mentioned. The goal is to identify high-opportunity prompts for content optimization.
Competitor Research lets you compare your AI visibility against up to 50 competitors. You manually add competitors and Semrush tracks share of voice across the AI platforms it covers.
Brand Performance monitors your share of voice, sentiment, and how AI describes your brand. Updated weekly. Prompt Tracking monitors your visibility on specific prompts with daily updates. AI Search Site Audit checks for technical issues that might prevent AI bots from crawling your site.
Semrush AI Toolkit currently tracks 5 AI platforms: ChatGPT, Google AI Mode, Google AI Overviews, Perplexity, and Gemini. It does not track Claude or Copilot (Microsoft). Copilot is only tracked in Semrush Enterprise AIO, the enterprise offer.
How much does Semrush AI Toolkit cost in 2026?
Semrush AI Toolkit costs $99/month per domain as a standalone product. That baseline includes 25 tracked prompts for one domain.
Extra domains cost $99/month each. Extra prompts and teammate seats are sold as paid add-ons. Tools that meter usage instead, such as RankScale, charge in credits.
For an agency managing 10 client domains, the cost would be $990/month before any prompt or teammate add-ons.
In 2026, Semrush also replaced its Pro, Guru and Business plans with an SEO + AI Search range. The SEO plan costs $139.95/month without AI prompts. Starter ($199/month), Pro+ ($299/month) and Advanced ($549/month) include 50, 100 and 200 tracked AI prompts, and Starter includes MCP access.
| Item | Cost |
|---|---|
| AI Toolkit (1 domain, 25 prompts) | $99/month |
| Additional domain | +$99/month each |
| Additional prompts, teammates | Paid add-ons |
| SEO plan (no AI prompts) | $139.95/month |
| Starter (SEO + 50 AI prompts, MCP) | $199/month ($165.17/month billed annually) |
| Pro+ (SEO + 100 AI prompts) | $299/month |
| Advanced (SEO + 200 AI prompts) | $549/month |
If you already need Semrush for SEO, a Starter, Pro+ or Advanced plan offers better value than buying the SEO suite and the AI Toolkit separately.
What does Semrush AI Toolkit do well?
Semrush's Prompt Research feature is genuinely useful for content strategists. It applies 16+ years of keyword research experience to AI prompts, with volume estimates, difficulty scores, and competitive data. If you're building an AI-focused content strategy, this depth of prompt data is hard to find elsewhere.
Geographic coverage is strong. Brand Performance supports 68,000+ locations worldwide, and prompt tracking covers 15+ regions. For global brands running international campaigns, this granularity matters.
The integration with Semrush's existing SEO tools means you can correlate traditional search rankings with AI visibility in one dashboard. If you're already paying for Semrush, adding AI tracking to the same workflow is seamless.
Competitor Research supports up to 50 tracked competitors per domain, which is useful for large brands in crowded markets who need to monitor a wide competitive landscape.

Why choose Mentionable over Semrush AI Toolkit?
Semrush AI Toolkit costs $99/month per domain for 25 prompts, and costs escalate quickly with add-on domains ($99 each) and extra prompts. Mentionable brings measurement, site work and external mentions into one tool, with an action plan that tells you what to do and in what order, without requiring an SEO suite subscription.
- An action plan, not just a dashboard. Mentionable reads your site, your Google Search Console data and what AI engines cite, then lays out one plan over 6 months: blocking technical fixes first, then the pages that sell, the pages that carry your prompts, buying guides and comparisons, and the sources to get mentioned on. Each action comes with its reason in real data. Semrush AI Toolkit gives AI-generated strategic recommendations in its Brand Performance report, and its AI Search Site Audit checks for technical issues that block AI bots.
- Pages drafted and rewritten. For a page to create, Mentionable drafts it from the Google top 3 and the pages AI engines cite, with JSON-LD, title and description tags, and the facts only you know highlighted instead of invented. An article to rework is rewritten from your live page. You copy it into your CMS, mark it published, and Mentionable shows when AI engines start citing it.
- Site health. Mentionable crawls your site every month and flags what stops AI engines from reading or citing it, in four levels. Pages that sell get a guided fix, and an applied fix is checked off at the next crawl.
- Claude included. Semrush AI Toolkit does not cover Claude. Mentionable includes Claude among the major AI engines it tracks.
- Measurement, site and mentions in one subscription. Semrush charges $99/month for 25 prompts on 1 domain, and each extra domain adds $99. Mentionable's brand plans, from €249/month, track the brand's questions across markets and add the monthly action plan for the site and the outreach that earns mentions.
- Automatic prompt generation. Semrush requires manually searching their prompt database. Mentionable scans the user's URL and suggests relevant prompts to choose from in minutes, with no research step.
- AI traffic analytics and source tracking. Mentionable's Google Analytics 4 integration shows the sessions ChatGPT, Perplexity and other AI sources send to the user's site. Mentionable also tracks which source domains LLMs cite in the user's category. Semrush AI Toolkit does not offer either feature.
- MCP integration. Mentionable ships an MCP server, like Semrush does from its Starter plan. Users can query their visibility data, including fan-outs, sources and backlink opportunities, directly from Claude, Cursor, ChatGPT, or Claude Code.
- AI assistant in the dashboard. Every Mentionable plan includes an AI assistant. You ask a question in plain words, such as why a competitor gets cited more often, and it answers from your project's data, then links to the page where you act. See the AI assistant.
- One-shot white-label GEO audit (agencies). Mentionable's agency offers include a client-ready GEO audit under your brand: competitor ranking, personas, competitor matrix, prompt coverage, recommendations, content ideas and top sources. Each section can be hidden, and the report is shared through a public link. A packaged deliverable for agencies that sell GEO to their clients.
Start tracking your AI visibility across the major AI engines with Mentionable's 7-day free trial, no credit card required.
