Tool comparison
Ahrefs Brand Radar vs Semrush AI Toolkit
The two dominant SEO-suite add-ons for AI visibility tracking — one priced as a bolt-on to a base Ahrefs plan, the other sold as its own toolkit.
Side by side
| Ahrefs Brand Radar | Semrush AI Toolkit | |
|---|---|---|
| Base requirement | Requires a base Ahrefs plan (from $129/mo) before Brand Radar pricing applies | Sold as a standalone toolkit at $99/mo per domain — no separate SEO subscription required, though it can bundle into Semrush One |
| Realistic monthly cost | $398/mo (select platforms) or $699/mo (all platforms) on top of the base plan — $528-828/mo total; reviewers cite $828-1,148/mo for full coverage | $99/mo for 25 prompts on one domain; +$60/mo per 50 extra prompts, plus separate domain/user add-ons |
| Engines tracked | AI Overviews, AI Mode, ChatGPT, Copilot, Gemini, Perplexity and Grok, plus beta YouTube/TikTok/Reddit mention tracking — no native Claude | ChatGPT, Google AI, Gemini and Perplexity only — no native Claude or Copilot |
| Prompt data source | Built on a real-query dataset (474M+ monthly prompts) rather than synthetic prompt generation | Prompt research generated as part of the toolkit, capped at 25 on the base plan |
Which should you choose?
Semrush AI Toolkit is the cheaper way in — $99/mo with no separate base-platform purchase required — but it caps out at 25 prompts on one domain and tracks four engines, missing Copilot entirely. Ahrefs Brand Radar tracks more surfaces (including Copilot and beta social platforms) and is built on real search-query volume rather than synthetic prompts, but only once you're already paying for a base Ahrefs subscription, which pushes realistic full coverage north of $800/month. If you're not already an Ahrefs or Semrush customer, factor in the base-platform cost before comparing the headline add-on prices directly.

Frequently asked questions
Do I need a full Ahrefs or Semrush subscription to use either?
Ahrefs Brand Radar requires a base Ahrefs plan (from $129/mo) before its add-on pricing applies. Semrush AI Toolkit is sold as a standalone toolkit at $99/mo per domain and does not require a separate core Semrush subscription, though it can also be bundled into a Semrush One plan.
Which tracks more AI engines?
Ahrefs Brand Radar covers more named surfaces — AI Overviews, AI Mode, ChatGPT, Copilot, Gemini, Perplexity, Grok, plus beta YouTube/TikTok/Reddit tracking. Semrush AI Toolkit tracks four: ChatGPT, Google AI, Gemini and Perplexity. Neither tracks Claude natively.
Which is cheaper for a single domain?
Semrush AI Toolkit's $99/mo entry price is lower than Ahrefs Brand Radar's realistic all-in cost, which starts around $528/mo once the required base Ahrefs plan is included — but Semrush's 25-prompt cap on that entry tier is tight for larger catalogs.
