What Brand Radar does
Brand Radar has two products. Custom Prompts runs the prompts you write on the AI platforms you pick, daily, weekly or monthly, and starts recording on the day you add a prompt. The AI Visibility Index draws on prompts Ahrefs collected and answers for them, with history back to 2025 for AI chatbot responses and to August 2024 for Google AI Overviews.
Ahrefs puts the size of the prompt database at more than 525 million on its Brand Radar and pricing pages, while its help article from 3 September 2026 says more than 405 million. Beta sources include YouTube, TikTok and Reddit, which are free while in beta for Lite and above and become a chargeable add-on afterward, according to the help article.
Ahrefs also offers Web Analytics for AI traffic, which is free, and Bot Analytics for AI crawler visits, which is free while in beta.
Ahrefs Brand Radar pricing in 2026
The pricing page counts usage in checks. One check is one prompt on one platform in one location. Claude uses 8 checks for each update.
Included with Ahrefs plans. Every paid plan includes custom prompt checks. Prices are those shown by default on the pricing page, which says annual payment saves up to 17%.
| Ahrefs plan | Price a month | Checks included | Prompts daily |
|---|---|---|---|
| Lite | $129 | 150 | 5 |
| Standard | $249 | 300 | 10 |
| Advanced | $449 | 600 | 20 |
| Enterprise | $1,499 | From 2,500 | From 83 |
Extra users cost $40 on Lite, $60 on Standard and $80 on Advanced, with one user included.
Standalone custom prompt packages.
| Package | Price a month | Checks | Overage per check |
|---|---|---|---|
| Basic | $50 | 2,500 | $0.020 |
| Growth | $100 | 7,000 | $0.015 |
| Scale | $250 | 25,000 | $0.010 |
AI Visibility Index. The Brand Radar page lists it at $199 a month with 83 prompts a day, 2,500 checks a month and all platforms, with overage at $0.020 a check. It lists $699 a month for all models under Custom Prompts. The help article reads these prices differently: $199 for one platform per index and $699 for all platforms, including 2,500 custom checks.
On how Brand Radar is sold, the pricing page says it is available standalone with an Ahrefs Free account, while the help article says the AI indexes need an add-on to any paid plan. Ahrefs says it never runs discounts and lists no Brand Radar trial.
Engines, refresh and history
The index covers Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot. Custom Prompts adds Claude, using Claude Sonnet 4.6 with web search. The pages disagree on Claude: the pricing block says the index has Claude available, while the help article and FAQ say Claude is for custom prompts only. Grok is listed in the help article, but the article says new data collection for it is paused.
Custom prompts run daily, weekly or monthly per platform. The index refreshes chatbot data monthly and AI Overviews every few days.
What Brand Radar does well
Brand Radar publishes deep history. The index holds chatbot responses back to 2025 and AI Overviews back to August 2024, which lets you see where a topic stood before you started tracking. Custom prompts are bundled into every paid Ahrefs plan, so an Ahrefs customer can start without a new contract.
Brands and domains are unlimited for AI visibility. The standalone packages publish their overage rates, and API and MCP access come with Lite and above. Ahrefs also states its own limits: the index works best for established brands or topics with search demand and may have limited coverage when search volume is low.
Where Brand Radar falls short
The package contents are unclear. The $199 and $699 prices read differently on the Brand Radar page and in the help article. So does the question of whether Brand Radar is standalone or an add-on.
Index data is monthly. Chatbot data in the index refreshes once a month, which is slow for noticing a change after an edit. Only custom prompts run daily.
Included checks go fast. Lite's 150 checks equal 5 prompt checks a day, which is 5 prompts on one platform. Tracking one prompt on six platforms daily uses 180 checks a month.
Seats cost extra. One user is included and more start at $40.
No trial and no discounts. You pay before you can test it on your own prompts.
Little coverage for small brands. Ahrefs says so itself.
Who Brand Radar fits
Brand Radar fits a team that already pays for Ahrefs and wants AI visibility beside keyword and backlink data, or an established brand that wants to study a category through the index. The standalone packages suit someone who wants to track their own prompts without the rest of the suite.
It fits less well a small brand with little search demand, or a team that needs daily answers on many platforms at a fixed monthly price.
Other tools to weigh against Brand Radar

Peec AI starts at $95 a month for 50 prompts on three models, with unlimited users. See the Peec AI review.

SearchSeal. SearchSeal costs $79 a month for 60 questions on Starter, $179 for 150 on Pro and $399 for 400 on Max, with unlimited brands sharing one question pool. It asks every question each day on AI Overview, ChatGPT, Gemini and Perplexity, and saves each answer with its mentions and returned source links. It has no index of prompts collected beyond your own questions. SearchSeal does not track crawler traffic or human visits from AI tools, and a returned source link is not proof the answer used that page. See SearchSeal vs Ahrefs Brand Radar. SearchSeal sells a competing product.
Is Ahrefs Brand Radar worth it?
It is worth it if you use Ahrefs already: the included checks cost nothing extra and the index adds history you cannot build yourself. If you are buying only for AI tracking, price your prompt list in checks first. Prompts times platforms times locations times days a month gives the number, and the packages' overage rates show what going past it costs.
Ask Ahrefs which reading of the $199 and $699 prices applies to your account before you pay.
