Ahrefs Brand Radar has two halves: an index of 514 million prompts you can search for any brand, and custom prompts you track yourself, metered in checks. Mentioned is free to start, runs Claude, ChatGPT and Gemini on us, and ranks what to fix first. Here’s what each one publishes.

Sources: ahrefs.com/brand-radar, ahrefs.com/pricing and mentioned.at/pricing, read October 28, 2026. Ahrefs’ pages show the $699 “for all models” figure beside the custom-prompts price without saying what it buys; check with Ahrefs before you budget on it.
Ahrefs meters custom prompts in checks. Its own footnote: “Each prompt is checked daily on every selected platform. 5 prompts on 1 platform = 150 checks/mo.” So daily tracking costs about 30 checks per prompt per platform each month, and Claude costs 8 checks per update. That gives these monthly ceilings for prompts tracked daily:
Track the same prompts on three platforms and divide by three; add Claude and each daily Claude update costs eight times as much. Checking weekly instead of daily stretches each package about seven times further. Mentioned has no meter: each plan includes its weekly runs on Claude and Gemini.
Ahrefs Brand Radar fits an SEO team already paying for Ahrefs that wants market-wide AI share from a large index, Google’s AI surfaces, and AI data next to its backlink and keyword work. Mentioned fits a B2B marketing team without an Ahrefs seat that wants to start free, cares most about what ChatGPT, Claude and Gemini say to buyers, and wants the next fix ranked for it.
On October 28, 2026, paid Ahrefs plans included Brand Radar custom prompts: 5 prompts and 150 checks a month on Lite ($129), 10 and 300 on Standard, 20 and 600 on Advanced. Extra custom-prompt packages started at $50 a month for 2,500 checks, and the AI Visibility Index cost $199 a month.
Ahrefs lists Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot, with Claude available. A Claude update uses 8 checks, against 1 for one prompt on another platform.
Mentioned has a free plan that needs no other subscription: 5 tracked queries, each five buyer questions, asked weekly on Claude and Gemini on our keys, plus 3 checks on us. It doesn’t cover AI Overviews, AI Mode or Copilot, and it has no market-wide prompt index.
Ahrefs’ pricing page says tracking one prompt on one platform in one location uses one check. Prompts are checked daily on each platform you select, so 5 prompts on one platform use 150 checks a month.
