Ahrefs Brand Radar vs Amplitude AI Visibility (2026)

Ahrefs Brand Radar and Amplitude AI Visibility are both AI-visibility tools, but they were built for two different buyers and they show it in almost every choice the product teams made.

Brand Radar is an add-on inside Ahrefs' SEO suite. To turn it on, you already need an active Ahrefs subscription starting at €119/month (about $133), then €179/month (about $200) per AI surface on top, or €654/month (about $732) for all five bundled. A fully-loaded setup that tracks every supported AI engine therefore starts around €773/month (about $865) before any extra custom-prompt usage, which is well above most dedicated AI-visibility trackers in this index. In return you get AI-answer mention tracking across Google AI Overviews + AI Mode, ChatGPT, Perplexity, Gemini and Microsoft Copilot: five surfaces in total, joined to Ahrefs' existing backlink, keyword and site-audit data, plus a YouTube, TikTok and Reddit mention-tracking module that is currently bundled free while in beta. The catch is that Claude, Meta AI and DeepSeek are not tracked, the data refreshes on a roughly monthly cadence rather than daily, and the comparison data you get is mention volume and share-of-voice rather than the optimization guidance some rivals ship.

Amplitude AI Visibility takes the opposite bet. It is a free feature inside every Amplitude analytics plan, including the perpetual $0 Free tier, with 500 tracked prompts at that level and up to 5,000 on Enterprise. There is no separate AI Visibility price. The engine coverage is narrower: ChatGPT, Google AI Overview, and Claude (added on the page hero, though the in-page FAQ still names only ChatGPT and Google AI Overview as 'monitored in all plans'). Perplexity and Gemini are no longer called out anywhere on the public page. What Amplitude trades away in engine breadth it spends on connection to revenue. Because the feature sits inside Amplitude Analytics, it can join AI-referred visits to session replay, conversion and revenue data, segment AI-sourced visitors, and follow the path from mention to purchase via Global Agent or MCP, which is a connection dedicated visibility-only trackers in this index do not offer. AI Visibility 2.0 (April 2026) also added sentiment analysis, a Recommendations panel, and a Search Volume beta that prioritises tracked prompts by real demand.

So the real choice is where AI-visibility data should sit. If your team lives in Ahrefs for SEO, Brand Radar is the natural first read on AI answers and the only one of the two that also brings backlink, keyword and YouTube/TikTok/Reddit context into the same view. If your team lives in Amplitude for analytics, AI Visibility is the natural first read, costs nothing, and is the only one of the two that lets you attribute AI mentions to revenue rather than just volume. Neither product is built for buyers who are not already customers of the parent suite: Brand Radar requires Ahrefs, and Amplitude's full revenue-attribution differentiator only matters if Amplitude is already where your traffic and revenue data live.
