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 (Anthropic) or Grok (xAI).
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 cost $60/month per 50 prompts. Adding a teammate with their own 50 prompts costs $258/month.
For an agency managing 10 client domains, the cost would be $990/month before any prompt or teammate add-ons.
| Item | Cost |
|---|---|
| AI Toolkit (1 domain, 25 prompts) | $99/month |
| Additional domain | +$99/month each |
| Additional 50 prompts | +$60/month |
| Teammate (50 prompts) | +$258/month |
| Semrush One bundle (SEO + AI) | From $165/month |
Semrush One bundles the AI Toolkit with their full SEO suite starting at $165/month. If you already need Semrush for SEO, the bundle offers better value than buying both 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.

What does Mentionable offer beyond basic tracking?
Mentionable is a complete AI visibility platform that goes well beyond mention monitoring. Here's what Mentionable includes in every plan:
Automatic prompt generation. Mentionable scans any website URL using AI and generates 15-20 relevant prompts based on the site's content and competitive landscape. No manual keyword research or prompt guessing needed. Users select which prompts to track, edit them, or add custom ones.
5 LLMs with no add-ons. Every Mentionable plan includes ChatGPT, Claude, Perplexity, Gemini, and Grok. There are no paid add-ons for additional LLMs. All 5 are scanned on every tracking run.
Competitor intelligence. Mentionable doesn't just check if your brand is mentioned. Mentionable's analysis pipeline extracts and normalizes every competitor mentioned alongside your brand, across all prompts and all LLMs. The competitor dashboard ranks them by mention frequency and shows exactly which prompts and which LLMs mention each competitor.
Source and citation tracking. Mentionable tracks every source domain that LLMs cite when answering prompts in your category. The sources page shows which websites AI considers authoritative in your space, and highlights whether your own domain is being cited or not.
Content opportunity analysis. Mentionable's fan-out pipeline uses AI to decompose each tracked prompt into 5 related search queries, deduplicates them across all prompts, clusters them by topic and intent type (comparative, how-to, definitional, transactional), and ranks them by priority. Each cluster represents a content piece to create or optimize for better AI visibility.
AI traffic analytics. Mentionable provides a tracking pixel that identifies website visits coming from LLMs. Since most AI-referred traffic appears as "direct" in Google Analytics, Mentionable's pixel correctly attributes visits from ChatGPT, Perplexity, Gemini, Grok, and Claude.
Sentiment analysis. Every prompt result includes sentiment classification (positive, neutral, or negative) per LLM, so brands know not just if they're mentioned, but how they're mentioned.
Mentionable Starter costs €29/month for 15 prompts across 5 LLMs. Mentionable Pro costs €89/month for 50 prompts and 3 projects. All plans include a 7-day free trial with no credit card required.
