Semrush AI Toolkit vs Ahrefs Brand Radar in 2026: which is best

If you already pay for Semrush or Ahrefs, the question is fair: why add a subscription when your suite ships an AI visibility module. The answer comes down to caps, and they are lower than the marketing suggests. Details below were read on their own pages on 16 September 2026.

Semrush: $99, but per domain and per seat

Semrush's AI visibility module lists at $99/month. That covers one domain and 25 tracked prompts, across ChatGPT, AI Mode and Gemini.

Two details change the total. Each additional domain costs another $99. More importantly, every team member who needs access requires their own licence, also at $99. At three people across two brands you are in a completely different price bracket. An extra 50 prompts costs $60.

Semrush also runs a free checker with no login, capped at three uses a day, which remains the most complete free offer in the category right now.

Ahrefs: bundled, with tight caps

Ahrefs includes Brand Radar in its paid plans, which sounds more generous. The caps tell a different story: 5 prompts and 150 checks a month on Lite at $129, 10 prompts and 300 checks on Standard at $249, 20 prompts and 600 checks on Advanced at $449.

Five tracked prompts cannot measure a category. To go beyond, Ahrefs sells add-ons: custom prompts from $50, an AI Visibility Index at $199/month, and a $699 tier covering all platforms. Their engine coverage is the broader of the two, though: AI Overviews, AI Mode, ChatGPT, Copilot, Gemini and Perplexity, with Claude available as an add-on.

When the suite is enough, and when it stops being enough

• Enough if you want to watch a dozen brand prompts and stay inside one tool.
• Enough if your SEO team is the only stakeholder and a single licence covers it.
• Not enough once several people need the data, because of Semrush's per-seat billing.
• Not enough if you have a catalog: neither documents product-level tracking or a Shopify integration.
• Not enough if you must report revenue: neither documents revenue attribution.

The question worth asking

These modules are designed as a natural extension of SEO work: track a brand, spot cited domains, adjust content. For that job they are coherent and well built. They are not designed around a product catalog, because that is not what these suites do.

If your question is "does my brand get cited", stay with your current vendor and save a subscription. If your question is "which of my 400 products show up, which ones are missing an attribute, and what is it worth", you are shopping for a different class of tool.
