When to choose each
Choose Spotaq when

Choose Ahrefs Brand Radar when
You need to explore a large index of search-backed AI prompts, connect AI visibility to search demand and SEO research, or track your own prompts within an existing Ahrefs workflow.
Side-by-side comparison
Both measure AI answer visibility. These differences help match the product to the work your team needs to do.
| Question | Spotaq | Ahrefs Brand Radar |
|---|---|---|
| Starting point | Run a free brand check without signup. | Preview a brand in the AI Visibility Index or configure Custom Prompts on an eligible plan. |
| Prompt approach | Uses buyer-intent questions for a brand baseline and shows missed prompts. | Combines a large search-backed prompt index with user-defined Custom Prompts; index coverage can be thinner for little-searched brands. |
| Evidence | Shows mentions, recommended competitors, AI answers, and cited domains. | Reports mentions, citations, AI share of voice, estimated impressions, and underlying AI responses. |
| Wider workflow | Focused audit, action list, and weekly monitoring on paid plans. | Connects AI visibility with Ahrefs search-demand and SEO data, including broader web, YouTube, and Reddit views. |
How to evaluate them fairly
If your brand is new, test the exact buyer questions you care about rather than assuming a large pre-collected index will include them. Ahrefs itself distinguishes its Index from Custom Prompts for low-search-volume or niche brands. Check each plan's current prompt allowance before comparing costs.
Compare the underlying answers for the same buyer questions. Scores can use different prompts, engines, sampling windows, and denominators. Neither product can guarantee an AI recommendation or citation.

Questions buyers ask
Does Ahrefs Brand Radar measure AI answers?
Yes. It tracks brand mentions, citations, share of voice, and AI responses through its Index and Custom Prompts. It should not be described as an SEO-only tool.
Is the Ahrefs Index the same as custom prompt tracking?
No. The Index draws from search-backed prompts and has existing data; Custom Prompts follow questions you define from setup onward. They answer different questions, particularly for niche brands.
Can I compare the two products' visibility scores directly?
No. Use the same buyer questions and inspect the actual answers, sources, and sampling dates. Different prompt sets or denominators can produce different scores.
