You don't need a full Ahrefs or Semrush subscription for AI visibility. Both sell it as add-ons on a paid base plan. When it pays off, and when to go dedicated.
Quick answer
No, you don't need a whole SEO suite for AI visibility. Ahrefs Brand Radar and the Semrush AI Visibility Toolkit are share-of-voice add-ons that ride on top of a paid base plan, so the real price is base + add-on (Ahrefs base ~$129+/mo plus a $398/$699 Brand Radar tier; Semrush base plus a ~$99/mo Toolkit) as of June 2026. If you already live in Ahrefs or Semrush for SEO and just want share-of-voice in the same dashboard, the add-on is convenient. If you're starting from the AI-visibility question, a dedicated monitor (Otterly ~$29/mo, Peec ~€89/mo) does share-of-voice cheaper — and for the serve/track side (llms.txt, bot logs, WebMCP) you need a dedicated tool like Crawlytics ($29.99/mo) regardless, because the suites don't do it and both publicly dismiss llms.txt. Buy the add-on if you're already paying for the suite. Otherwise go dedicated: a monitor plus a serve/track tool, usually for less than the add-on alone.
The question I get from people new to AI search is almost always framed as a subscription decision: "I already pay for Ahrefs, do I just turn on the AI thing?" or "Should I get Semrush for this?" The honest answer is that the framing is slightly off. AI visibility isn't a feature you flip on inside a suite you already own. It's a separate add-on with its own price, and there's a cheaper, more capable path if you build the stack deliberately instead of defaulting to the suite you happen to be logged into.
I run Crawlytics, which sits on the serve-and-track side of this market, not the share-of-voice side. So take my read with that disclosure in mind. But the pricing math here isn't a matter of opinion, and the gap in what the suites do versus what AI visibility actually requires is structural. Let me lay it out.
"Do I need Ahrefs or Semrush for AI visibility" is really two questions wearing one coat.
The first is about share of voice: how often do ChatGPT, Perplexity, Gemini, and Google AI Overviews mention your brand versus your competitors when someone asks a buying question? That's the metric Brand Radar and the AI Visibility Toolkit sell. It's also the metric every dedicated monitor sells. Share of voice is a crowded, well-defined category, and the suites are late, premium-priced entrants in it.
The second question is about serving and fixing: is your site actually readable to AI fetchers, are you publishing an llms.txt, which bots are crawling you, and can agents transact on your site? None of that is share-of-voice. None of it is something Ahrefs or Semrush do. And it's the half of AI visibility you can actually control with engineering, rather than just measure. The distinction between measuring AI search and serving it is the same one I draw in AEO vs SEO vs GEO.
So the real decision isn't "Ahrefs or Semrush." It's "do I bolt share-of-voice onto a suite I already pay for, or do I assemble a dedicated stack that covers both halves for less." The rest of this post is the evidence for that decision.
Ahrefs Brand Radar (ahrefs.com) is the AI-search add-on to the Ahrefs suite. It tracks how often your brand appears in AI answers, built on Ahrefs' search-backed prompt data, and shows trends over time and against competitors. If you've used Ahrefs for keyword and backlink work, it lives in the same interface you already know, which is the genuine appeal.
Three things to be clear-eyed about, as of June 2026:
Ahrefs also offers a free AI Visibility Checker with no signup, which is a fine way to sample the data before you commit to anything. Use it. Just don't mistake the free checker for the paid product.
Semrush (semrush.com) packages its AI features as the AI Visibility Toolkit, again an add-on rather than a standalone plan. It covers brand mentions across AI engines, share-of-voice trends, and recommendations, and like Ahrefs it slots into a dashboard SEO teams already use daily.
The cost and coverage picture, as of June 2026:
Semrush also has a free AI visibility checker, same logic as Ahrefs: a good sampler, not the paid tier.
Here's the part that decides the question for a lot of people. Both Ahrefs and Semrush are measurement layers. They tell you whether you're mentioned. They do not give you the levers to change it on the technical side, and three specific levers are simply absent from both:
No llms.txt — and they argue against it. Neither suite generates or serves an llms.txt file, the emerging convention for telling AI crawlers which pages matter and how to read them. More pointedly, both Ahrefs and Semrush have publicly dismissed llms.txt as ineffective. That's a defensible editorial position to hold, but it means if you do want to publish and serve llms.txt, the suites are not just silent on it, they're philosophically opposed. You'll need a dedicated tool either way.
No WebMCP or agent commerce. Neither suite touches the agentic-web layer, where in-browser AI agents discover tools on your site and act on them. That category is new and still settling, but it's zero coverage from both Ahrefs and Semrush.
Bot/log tracking is gated or estimated. Ahrefs' real-log bot tracking is a Cloudflare-only beta. Semrush's AI traffic is third-party estimates. Neither gives most users clean, first-party, server-log visibility into which AI bots fetched which pages, when, and how often. That signal is the foundation of knowing whether your serve-side work is landing.
So even if you buy the add-on, you've solved exactly one half of AI visibility: the monitoring half. The serve-and-fix half is untouched, and you'll be shopping for a second tool regardless of which suite you picked.
This part is genuinely situational, so here are the decision rules I'd actually use.
The pattern underneath these rules: the suite add-on wins on convenience for existing suite users, and loses on cost and capability for everyone else.
If the rules above point you toward dedicated, here's the stack and roughly what it costs, so you can compare apples to apples against base + add-on.
1. A share-of-voice monitor. This is your replacement for Brand Radar / the AI Visibility Toolkit. Otterly starts around $29/mo and Peec around €89/mo as of June 2026, both purpose-built for prompt-sampling share-of-voice across AI engines. Either one gives you the "am I mentioned, and how do I compare" signal that the suite add-ons sell, usually at a lower price than a suite base plan alone. I round up the affordable options in the best AI brand monitoring tools and, for the sub-$50 bracket specifically, in the best AI visibility tools under $50.
2. A serve-and-track tool. This is the half the suites don't cover, and it's where Crawlytics fits. Crawlytics ($29.99/mo Visibility) generates and serves your llms.txt, serves clean HTML and markdown to AI fetchers, and reads your own server logs to show exactly which AI bots fetched which pages. Because one tool both generates the llms.txt and reads the logs, it can show your llms.txt coverage gap — pages you declared that no bot actually fetched — which a standalone generator structurally can't. The Commerce tier ($49.99/mo) adds WebMCP agent commerce with conversion attribution. Full disclosure: this is my product, and on the share-of-voice side it's deliberately not a competitor — Crawlytics does not do multi-prompt brand-mention sampling, which is exactly why you pair it with a monitor rather than replacing one.
Run the math against a real scenario. A monitor at $29/mo plus Crawlytics Visibility at $29.99/mo is roughly $59/mo and covers both halves of AI visibility. Ahrefs base ($129+) plus a Brand Radar tier (~$398) is north of $500/mo and covers only the monitoring half. Even Semrush base plus the ~$99 Toolkit lands well above the dedicated pair, and still leaves you needing a serve/track tool. The dedicated stack isn't just cheaper on the share-of-voice line, it does strictly more. You can see how Crawlytics is priced in full on the pricing page, and a broader build of the dedicated approach in the best Profound alternatives.
The one honest caveat: if you genuinely value having AI visibility inside the SEO dashboard your team already opens every morning, that integration has a value the savings might not beat. That's the real trade, and only you can price it.

No. Ahrefs Brand Radar is an add-on to a paid Ahrefs base plan, so you would be buying a full SEO suite plus an add-on just to track AI share of voice. If you already use Ahrefs for SEO it is a reasonable bolt-on, but if AI visibility is your starting point, a dedicated share-of-voice monitor handles that job for far less, and you still need a separate tool to serve llms.txt and read your own bot logs.
As of June 2026 Ahrefs Brand Radar is sold as an add-on with tiers around $398 and $699 per month, and it requires an active Ahrefs base plan (around $129+/mo) underneath it. So the realistic all-in cost is base plan plus the add-on, not the add-on price alone. Check ahrefs.com for current pricing, which changes.
It is worth it mainly if you already pay for Semrush and want share-of-voice data inside the same dashboard. The AI Visibility Toolkit is roughly a $99/mo add-on on top of a Semrush base plan, and its AI traffic numbers are third-party referral estimates rather than your own server logs. If you are not already a Semrush user, a standalone monitor gives you the same core share-of-voice signal for less.
For share-of-voice monitoring specifically, dedicated tools like Otterly (around $29/mo) and Peec (around €89/mo) are cheaper than a suite base plan plus an add-on. For the serve-and-fix side — generating and serving llms.txt, reading your own AI-bot server logs, and agent commerce — you need a dedicated tool like Crawlytics ($29.99/mo Visibility), because the suites do not do those jobs at all.
No. Neither Ahrefs nor Semrush generates or serves an llms.txt file, and both have publicly argued that llms.txt is ineffective or a distraction. They are measurement layers, not publishing layers. If you want to publish and serve llms.txt and then verify which AI bots actually fetch those pages, you need a tool built for that, such as Crawlytics.
