ClarAI vs Ahrefs
Best for teams that want brand monitoring backed by a very large independent prompt corpus and have the budget for a suite-level plan. Below is how the two products actually differ, with credit where Ahrefs has earned it.
Who Ahrefs Brand Radar are
Ahrefs Brand Radar is the AI visibility module inside Ahrefs, and its moat is corpus scale. When we read its page on 13 October 2026, Ahrefs put the database at 475M+ total monthly prompts, the largest shares from Google AI Overviews and AI Mode. For a team that wants brand monitoring backed by one of the largest independent web datasets, Brand Radar is a serious offer.
Pricing sits at the suite level: when we re-read the page on 14 October 2026 with its currency set to US dollars, Custom Prompts started at $50 per month as an add-on (included free in paid Ahrefs plans), the all-models tier was published at $699 per month, and the AI Index add-on at $199 per month, all on top of an Ahrefs base plan. The page otherwise prices in the visitor's currency (it showed EUR 47, EUR 654 and EUR 179 to our fetch). The comparison with ClarAI is monitoring scale on one side and a lower-cost action-plus-honesty product on the other.

| Dimension | Ahrefs | ClarAIEarly access |
|---|---|---|
| Pricing | Custom Prompts from $50 per month as an add-on (free in paid Ahrefs plans); the all-models tier is published at $699 per month and the AI Index add-on at $199 per month, on top of an Ahrefs base plan. Dollar figures as the page showed them with its currency set to US dollars on 14 October 2026; it otherwise prices in the visitor's currency. | Free tier with 1 brand project, or Pro at $99 per month (early access pricing). |
| Delivery model | Self-serve, as the Brand Radar module inside the Ahrefs suite. | Self-serve product. The specialist work is done by agents inside the product, with your team reviewing and approving the output. |
| Engines covered | The page names ChatGPT, Gemini, Microsoft Copilot, Perplexity, Google AI Overviews and Google AI Mode, with Claude available on the AI Visibility Index, where a Claude update uses 8 checks (read 13 October 2026). YouTube, TikTok and Reddit are bonus sources for Ahrefs customers, free while in beta. | Three engines: ChatGPT, Gemini and Claude. Google AI Overviews is built but not switched on yet. |
| Monitoring depth | Corpus-scale: 475M+ total monthly prompts by Ahrefs' own figure (read 13 October 2026), the largest shares from Google AI Overviews and AI Mode. | Prompt-level monitoring built from your personas and buying stages, with per-engine sample counts, citation tracking, competitor share, and run-over-run history. |
| Action layer | Positioned as brand monitoring inside the Ahrefs suite; a built-in layer that drafts and routes the fixes is not part of the offer in our research. | Built in: an action plan executor, a content engine with 11 deliverable types, and a community CRM with reply drafting and approval routing. |
| Honesty features | Publishes large corpus and check-volume figures. Per-run sample-size or variance disclosure on your brand's scores: not published in our research. | Coverage badges (for example, 4 of 72 prompts measured), measured vs unmeasured prompt scores, per-engine sample counts, and the raw answers plus citations behind every number. |
| API and white-label | Part of the Ahrefs platform, which has its own API surface; Brand-Radar-specific API and white-label terms are not published in our research. | Programmatic API with scoped keys, plus an MCP server for AI assistants. On the Agency plan, white-label PDF reports carry your agency's name and logo, and each client can get a read-only report link. Not built yet: that link on your own domain, and your branding inside the app. |
The honest recommendation
Choose Ahrefs if
- You want brand monitoring backed by one of the largest independent web datasets; a corpus Ahrefs puts at 475M+ monthly prompts has real scale.
- You already use Ahrefs or want AI visibility to sit inside a mature SEO suite.
- You have budget for a suite-level Ahrefs plan plus its AI add-ons.
- You need monitoring breadth and corpus scale more than a built-in tool to produce the fixes.
Choose ClarAI if
- You want the tool to also produce the fix: drafted content, executed tasks, and community replies routed through approvals, not monitoring alone.
- You want sample-size and coverage disclosure on every number, with the raw answers one click away, rather than a corpus figure standing in for confidence.
- You want a $99 self-serve entry rather than a suite-level plan approaching four figures a month.
- You are comfortable being an early user of a new product. ClarAI is pre-launch; Ahrefs is an established suite.
The structural difference: corpus scale vs action plus honesty
Ahrefs' corpus is a real advantage. A database of 475M+ monthly prompts, by Ahrefs' figure, is something no tool at ClarAI's price can match, and we do not pretend to.
ClarAI's bet is that for most brands the binding constraint is not a bigger corpus. It is that nobody does the work the monitoring implies, and that a large dataset figure is not the same as disclosed confidence on your own numbers. So ClarAI puts the budget into the action layer and the honesty layer: an executor that drafts the fixes, a content engine for the deliverables, community tools that carry drafts to an approval queue, and coverage badges plus sample counts on every score, at $99 per month.
If you want corpus-scale brand monitoring inside a mature suite and the budget fits, Brand Radar is a strong choice. If you want the monitoring wired to the doing, with every number backed by visible receipts, that is ClarAI.
