03 — Strengths & limits

Prominara

Strengths

Standalone: Pro ($149/month) tracks 50 prompts on ChatGPT, Perplexity, Gemini, Google AI Overviews, and Google AI Mode with no SEO suite underneath
When you change a page, its prompts are re-asked 3 times in 3 phrasings and compared against untouched control prompts; the verdict is a probability with a range and an evidence grade
Headline visibility rate excludes prompts that already name your brand, so the number reflects being found rather than being asked about
Page-level AI-readiness audits with prioritized fixes, plus an AI writer that drafts briefs and full pages from the sources AI cites for each prompt
Flags answers that state wrong facts about your brand and gives a correction plan
White-label reports, client portal, and multi-client workspaces for agencies

Limitations

No market-wide index: Prominara measures the prompts you track, not hundreds of millions of pre-collected prompts
Checks weekly at most; Brand Radar custom prompts can run daily
5 AI surfaces; no Claude or Microsoft Copilot
No backlink, keyword, or rank-tracking tools
Newer, smaller company

Ahrefs Brand Radar

Strengths

Index of 492M+ prompts lets you benchmark any brand with no setup
Custom prompts cover Claude as well as the six index platforms
Daily cadence available for custom prompts
Sits next to Ahrefs backlink, keyword, and site audit data
Every paid Ahrefs plan includes a small daily custom-prompt quota (5 prompts on Lite)

Limitations

Requires a paid Ahrefs plan; Lite starts at $129/month before any Brand Radar index
Each AI platform index costs $199/month; all indexes cost $699/month
Index question sets are re-tested monthly on a 90-day reporting window
No published method for measuring whether a specific content change moved AI visibility

The verdict

Which tool wins, for whom.

Ahrefs Brand Radar answers "how visible is this brand across AI, compared with the market?" Its 492M-prompt index and daily custom prompts, including Claude, make it a strong benchmarking tool for teams already paying for Ahrefs. Prominara answers a narrower question: did the change you shipped move AI visibility for the prompts you care about? It re-asks each changed prompt 9 times, compares against prompts you did not touch, and reports a probability with a range. It also audits pages, drafts content from cited-source evidence, and checks AI answers for wrong facts about your brand. Covering every AI platform in Brand Radar costs $828/month ($129 Lite plus $699 for all indexes); Prominara Pro covers its 5 surfaces for $149/month.

Choose Prominara if

You want a dedicated AI visibility workflow without an SEO suite underneath, you need to show which content changes moved AI visibility, you want AI to draft while your team decides what goes live, or you run an agency and need white-label reports.

Choose Ahrefs Brand Radar if

You already pay for Ahrefs, you need market-wide benchmarks across hundreds of millions of prompts, or you need Claude, Copilot, or daily readings for your custom prompts.

04 — Questions

Frequently asked.

01Is Prominara a good Ahrefs Brand Radar alternative?

Yes, if you need to improve and measure your own AI visibility rather than benchmark the market. Prominara tracks your prompts on 5 AI surfaces, audits pages, drafts content, and reports whether each change worked. Ahrefs Brand Radar offers a 492M-prompt index, daily custom prompts, Claude and Copilot coverage, and the full Ahrefs SEO suite.

02How much does Ahrefs Brand Radar cost?

As of October 2026, Ahrefs Brand Radar requires a paid Ahrefs plan (Lite $129/month and up) and costs $199/month per AI platform index or $699/month for all indexes. Custom prompt packs cost $50 to $250/month on top. Prominara is standalone at $29, $149, or $299 per month with a 14-day free trial, and Pro ($149) includes all 5 of its AI surfaces.

03Can I use Ahrefs Brand Radar without an Ahrefs subscription?

04Does Ahrefs Brand Radar track Claude?

Yes, through custom prompts. Ahrefs Brand Radar's AI Visibility Index covers AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, and Copilot, and its custom prompts add Claude. Prominara tracks ChatGPT, Perplexity, Gemini, Google AI Overviews, and Google AI Mode, and does not track Claude or Copilot.

05Does Ahrefs Brand Radar measure whether content changes worked?

Ahrefs Brand Radar shows visibility trends but does not publish a method for attributing a change to a specific page update. Prominara re-asks each changed prompt 3 times in 3 phrasings, compares against untouched control prompts, and reports a probability, a range, and an evidence grade at 7, 14, and 28 days. The method is published at prominara.com/methodology.

06Ahrefs Brand Radar vs Prominara for agencies?

Prominara includes white-label reports from its $149 Pro plan and adds unlimited reports, a client portal, and multi-client workspaces on its $299 Agency plan. Ahrefs Brand Radar does not list white-label AI visibility reports or a client portal on its Brand Radar page.

07Can I use Prominara and Ahrefs together?
