Ahrefs Brand Radar measures brand mentions and share of voice across AI answer indexes, sold as pre-built indexes per platform from about $129 a month, with a free tier included. Buyers who need the actual AI answer behind one buyer question, not an aggregate index number, look elsewhere.
The two things that send an Ahrefs Brand Radar buyer looking elsewhere are price and evidence depth. Brand Radar's AI indexes are sold per platform on top of the entry tier, so a team that wants broad coverage across several AI surfaces can end up paying for each index separately rather than one flat price. The other gap is depth: Brand Radar reports mentions and share of voice as a category-wide trend line, which is useful for watching a market move, but it does not hand you the specific AI answer, the competitor named instead of you, or the source that answer cited.
Bottom line: if you already track SEO in Ahrefs and just want a directional AI trend line next to it, Brand Radar fits. If you need the sentence that cost you a mention, you need the raw answer, not the index.
Our full ranking, the 10 best AI visibility tools in 2026, covers ten vendors in depth. Here is how the tools an Ahrefs Brand Radar buyer compares most often stack up side by side:
| Tool | Engines measured | How answers are shown | Free tier | Starting price | Who it fits |
|---|---|---|---|---|---|
| Ahrefs Brand Radar | Sold as pre-built AI indexes per platform, up to 6 | Mentions / share of voice | Yes, included with a free Ahrefs account | ~$129/mo entry; indexes ~$199 each or ~$699 for all six | Teams that want AI share of voice next to existing Ahrefs SEO data |
| Profound | ChatGPT, Gemini and Google AI Overviews on the trial; Claude and others on higher tiers | Composite scores; agent-run credits | No ongoing free plan (one-time trial) | see vendor pricing page | Enterprise teams wanting agent-level analytics |
| Semrush AI Toolkit | ChatGPT, Google AI, Gemini, Perplexity, no Claude | Share of voice + sentiment | No standalone free tier | see vendor pricing page | SEO teams already paying for Semrush |
| Peec AI | 3 of 6 models per plan, from a pool of ChatGPT, Google AI Mode, AI Overviews, Copilot and Gemini; Claude not listed | Visibility % + cited sources per prompt | Free trial only | see vendor pricing page | Teams that want to build a large, custom prompt set |
| Scrunch AI | 6 engines bundled into one tier, not individually published | Visibility + readiness score, with content fixes | Partial free trial for content work | see vendor pricing page (reported ~$250/mo) | Enterprise content teams inside or near the Sitecore ecosystem |
| Reflexa | ChatGPT, Claude, Perplexity | Raw AI answer + sources attached to every finding | Yes, first check free, no card, ~3 min | $49/mo | Teams that want a measurement they can defend, not a black-box index |
Proof: engine and evidence details above reflect each vendor's own published tier information as surveyed in our wider 10 best AI visibility tools ranking, September 2026, including Ahrefs Brand Radar's reported ~$129/month entry tier and per-index add-on pricing. This run could not reach the vendors' own pricing pages (network blocked), so prices beyond what is already published on our own site are left to the vendor's own page rather than guessed or copied from a review site. Reflexa's price is published on our own pricing page.
Note: engines and indexes listed are each vendor's own published tier limits, not a claim about what they technically can query; a higher tier usually unlocks more.
Ahrefs Brand Radar and Profound both report on AI mentions at scale, but for different starting points. Brand Radar sits inside the Ahrefs product a team may already use for SEO, and it adds AI indexes as a priced extra rather than a core bundled feature. Profound is built specifically for AI visibility from the start, with agent-traffic analytics and a wider set of engines unlocked on its higher, enterprise-priced tiers.
Pick by starting point: Ahrefs Brand Radar for a team that already lives in Ahrefs and wants AI mentions as one more index; Profound for a team starting from scratch on AI visibility with an enterprise budget.
Reflexa is the one in this comparison that attaches the complete AI answer and its sources to every finding, per engine. Ahrefs Brand Radar reports mentions and share of voice across its AI indexes, which shows a brand's relative position in a category but not the exact sentence an engine used to skip it, the way Reflexa's public AI Visibility Index does. Profound, Semrush AI Toolkit, Peec AI and Scrunch AI each report a score, a percentage or a share-of-voice figure as the primary output too.
Why it matters: you cannot fix an answer you cannot read. A share-of-voice index tells you whether you are trending up or down in a category; the raw answer tells you which sentence, which competitor and which source cost you the mention.
We asked ChatGPT, Claude and Perplexity 100 real buyer questions about AI visibility tools in September 2026 and counted the names in all 300 answers. This is the same kind of measurement these tools sell, run on their own category:
| Tool | Answers naming it (of 300) |
|---|---|
| Profound | 94 |
| Semrush | 67 |
| Otterly.AI | 49 |
| Peec AI | 49 |
| Ahrefs | 39 |
| SE Ranking | 21 |
| Scrunch AI | 19 |
Proof: Reflexa AI Visibility Index, September 2026 (100 buyer questions about AI visibility tools, 3 engines, 300 observed answers, counted by name).
Read it as rank, not market share: 39 of 300 is roughly one in eight answers, fifth of the seven tools we tracked, ahead of SE Ranking and Scrunch AI but well behind Profound and Semrush, which lines up with Brand Radar's position as an add-on to an existing SEO workflow rather than a standalone AI visibility product.
You can shortlist an Ahrefs Brand Radar alternative without buying anything yet:
Reflexa, Profound, Semrush AI Toolkit, Peec AI and Scrunch AI are the tools buyers compare Ahrefs Brand Radar against most often. Which one fits depends on whether you want the actual AI answer behind one buyer question instead of an aggregate share-of-voice number, and whether you want to pay per AI index or one flat monthly price.
Ahrefs Brand Radar fits a team that already tracks SEO rankings in Ahrefs and wants AI mentions as a category-wide trend line next to that data. Profound fits an enterprise analytics team that wants agent-traffic data and a wider set of engines on its higher tiers. Neither publishes a full per-answer evidence log the way Reflexa does.
Ahrefs Brand Radar sells its AI indexes per platform rather than one fixed bundle, so which specific engines are covered depends on which indexes you buy. Confirm the current index list and what each one measures on Ahrefs' own pricing page before assuming ChatGPT, Claude and Perplexity are all included.
Reflexa attaches the full raw AI answer and its sources to every finding, for ChatGPT, Claude and Perplexity. Ahrefs Brand Radar reports mentions and share of voice across AI indexes, which is useful for a category-wide trend line, but it does not publish a complete answer-by-answer evidence log the way Reflexa does.
Reflexa's first check is free, no card required, and takes about three minutes, with Claude included from the start. Confirm Ahrefs Brand Radar's current pricing on its own site, since its reported entry price of about $129/month does not include the per-platform AI index add-ons, and self-serve tiers in this category change often.
The free check reads your pages the way ChatGPT, Claude and Perplexity read them — 23 structural checks, evidence attached, no card needed.
