Semrush is a name you probably know. They've been in the SEO game since 2008 and have built one of the most comprehensive marketing toolkits out there. In late 2025, they launched their AI Visibility Toolkit to help brands track how they appear in AI search results.
If you're considering it, here's what you need to know.
How Semrush AI Toolkit works
The toolkit is built around six main features.
Visibility Overview gives you a benchmark score of how visible your brand is across AI platforms. Think of it like Domain Authority, but for AI search.
Competitor Research lets you compare your AI visibility against competitors. You can track up to 50 competitors to see where you're winning and where you're getting outranked.
Prompt Research is their version of keyword research for AI. You find prompts in your industry, see their "AI volume", difficulty, and which brands are getting mentioned. The idea is to find high-opportunity prompts and create content to rank for them.
Brand Performance tracks your share of voice, sentiment, and how your brand is being described across AI platforms. Updated weekly. Prompt Tracking monitors your visibility for specific prompts with daily updates. And AI Search Site Audit checks for technical issues that might prevent AI bots from crawling your site properly.
What it costs
The standalone AI Visibility Toolkit is $99/month per domain.
That's the baseline. Want to track another domain? Add $99/month. Need more than 25 prompts? Add $60/month for 50 more. Want a team member with their own prompts? $258/month for one teammate with 50 prompts.
If you're an agency managing 10 clients, you're looking at $990/month just for the AI toolkit. Before any add-ons.
Semrush also offers Semrush One, a bundle that combines their classic SEO toolkit with AI visibility. It starts at $165/month for the Starter tier, which might make sense if you need both. But if you're just looking for AI visibility tracking, you're paying for a lot of features you won't use.
What Semrush does well
Coverage is solid. They track ChatGPT, Google AI Mode, Google AI Overviews, Perplexity, and Gemini. That's the major AI platforms.
The depth of data is impressive. The Prompt Research feature is genuinely useful if you're doing content strategy. It's basically keyword research adapted for AI, and Semrush has years of experience making that kind of data actionable.
Geographic reach covers 15+ regions, and Brand Performance supports 68,000+ locations worldwide. If you're tracking a global brand, this matters.
If you're already a Semrush user, having AI visibility in the same dashboard makes sense. You can see how your traditional SEO and AI visibility correlate.
Where Mentionable takes a different approach
We built Mentionable for a different use case.
Semrush is an enterprise tool for marketing teams running full-scale SEO operations. You need to manually research and define which prompts to track.
Mentionable works differently. You enter your URL, we suggest 15-20 relevant prompts based on what you offer. You pick which ones to track, or add your own custom prompts. Then we monitor those across 5 LLMs: ChatGPT, Perplexity, Grok, Gemini, and Claude.
Semrush charges $99/month per domain. Mentionable's Starter plan at €29/month includes 1 project, Pro at €89/month includes 3 projects, and the Agency plan at €179/month has unlimited projects.
Different approaches for different needs. With Semrush, you do extensive prompt research, then set up tracking. With Mentionable, we suggest prompts to get you started fast, but you can track whatever you want.
Which one fits you?
Semrush AI Toolkit makes sense if:
- You already use Semrush for SEO and want everything in one place
- You need enterprise-level data: 50+ competitors, 68,000+ locations, sentiment analysis
- You have budget for $99+/domain and aren't price-sensitive on add-ons
- You want to do AI "keyword research" and build a content strategy around prompts
- You run an agency with clients who need comprehensive reporting
Mentionable might be better if:
- You want to start free and see results before paying anything
- You care about purchase-intent visibility, not brand sentiment
- You're a solopreneur or small team without enterprise needs
- You want simple answers, not another dashboard to learn
- You want unlimited projects on Agency plan (€179/month) vs $99/domain
The bottom line
Semrush AI Toolkit is a powerful tool for teams that need comprehensive AI visibility data integrated with their SEO workflow. If you're already in the Semrush ecosystem and have the budget, it's a logical addition.
But if you're a solopreneur or small business owner who just wants to know if AI is sending you clients, Semrush is probably overkill. You'll pay $99/month minimum for features you won't use, and you'll spend time learning a dashboard when you just want answers.
Try Mentionable with a 7-day free trial. Run a scan. See if you're visible on the queries that actually drive revenue. Pro at €89/month gives you 50 prompts across all 5 LLMs. You can always upgrade to enterprise tools later if you need them.
