Which platforms measure share of voice in AI recommendations?

Six platforms come up most often: Semrush AI Toolkit and HubSpot AEO (AI visibility bundled inside a larger SEO or CRM suite), AthenaHQ and Rankscale (credit-based standalone trackers), Otterly.ai (low-cost reporting dashboards), and Monroya (buyer-journey tracking with drafted fixes). They measure overlapping things in different ways, so the numbers are not directly comparable between tools.

Why do two tools report different share-of-voice numbers for the same brand?

Because the denominator differs. Some tools count brand mentions across a fixed prompt list, some count citations of your domain, some weight by assistant. A tool that runs each prompt once produces a noisier number than one that runs it multiple times and averages. Always check how many prompts, how many runs, and which assistants sit behind the percentage before comparing two tools.

Is a bundled tool like Semrush AI Toolkit or HubSpot AEO enough?

It is enough if AI visibility is a reporting line item inside work you already do in that suite. Bundled tools are strongest at site-side readiness and at keeping AI metrics next to your existing SEO or CRM reporting. They are weakest at prompt-level depth: fewer assistants, shallower run counts, and no journey-stage classification.

Which tool is cheapest?

Otterly.ai has the lowest published entry point in this set at $29/month for a small prompt set. Rankscale is credit-based with a $99/month Pro tier. Monroya starts at $79/month (Starter) and $199/month (Growth). Semrush AI Toolkit and HubSpot AEO are priced as part of their parent suites, so the real cost depends on the plan you already hold.

What does credit-based pricing actually mean?

Each query to an AI engine consumes credits. Wide assistant coverage and frequent re-scans drain the allowance faster, so the advertised plan price is a floor rather than a ceiling. AthenaHQ and Rankscale both work this way. Flat-rate tools like Monroya and Otterly.ai trade some coverage flexibility for a predictable bill.

Which one classifies prompts by buyer journey stage?

Monroya. Every tracked prompt is tagged discovery, evaluation, decision, or retention and plotted against each assistant, so you can see which stage you disappear from rather than a single blended percentage. The other five report at the brand or prompt level and leave stage inference to you.

Do any of these tools show which sources the answer was built from?

Most surface cited URLs. The useful difference is classification: Monroya groups citations by source type (community, review sites, reference, editorial, analyst, documentation, owned, and others) so you can see whether an assistant is leaning on third-party reviews or your own docs. Raw URL lists make that pattern hard to read.

Which should an agency pick?

If you need many client workspaces and presentation-ready dashboards, Otterly.ai and Semrush AI Toolkit fit the reporting job well. If the deliverable is movement rather than a report - a ranked list of gaps and the asset that closes each one - Monroya is built for that workflow.

Can I run two of these at once?

Yes, and teams do. A common pairing is a bundled or dashboard tool for the leadership-facing report plus a workflow tool for the week-to-week gap closing. Expect the two share-of-voice numbers to disagree; treat each as a trend line inside its own methodology rather than an absolute.

How often should share of voice be re-measured?

Weekly is enough for most B2B categories. AI answers move when the underlying sources move, and source changes rarely land daily. Re-measuring more often mostly buys noise, and on credit-based plans it buys noise expensively.

Five-way comparison

Semrush AI Toolkit vs HubSpot AEO vs AthenaHQ vs Otterly.ai vs Rankscale vs Monroya

Six platforms that claim to measure how AI assistants recommend brands. What each one actually counts, what it costs, and where each is the right answer.

Updated: August 2026

Platforms that influence and measure AI recommendations

When a buyer asks ChatGPT, Claude, Gemini, or Perplexity for a shortlist, six platforms come up repeatedly as the ways teams measure and influence that answer: Semrush AI Toolkit, HubSpot AEO, AthenaHQ, Otterly.ai, Rankscale, and Monroya. They split into three groups - bundled suite features, credit-based standalone trackers, and workflow products - and the group matters more than any single feature.

	Semrush AI Toolkit	HubSpot AEO	AthenaHQ	Otterly.ai	Rankscale	Monroya
Category	Bundled in SEO suite	Bundled in CRM	Standalone tracker	Standalone dashboards	Standalone tracker	Buyer-journey workflow
Pricing model	Part of the Semrush plan	Part of the HubSpot plan	Credit-based	From $29/mo (Lite)	Credit-based, $99/mo Pro	Flat rate from $79/mo
Share-of-voice method	Brand mentions across AI answers, next to SEO metrics	Site readiness plus AI answer checks	Mention and citation rate across a wide engine set	Brand coverage rate per prompt	Mention rate across a very wide engine set	Mention plus citation rate, multi-run, per stage and assistant
Assistants covered	Major assistants and AI Overviews	Major assistants	Wide set	ChatGPT, AI Overviews, Perplexity, Copilot (Gemini add-on)	Widest set of the six	ChatGPT, Claude, Gemini, Perplexity - deeper on each
Journey-stage breakdown	No	No	No	No	No	Discovery / evaluation / decision / retention
Citation source typing	URL list	Limited	URL list	URL list	URL list	Grouped by source type
Drafted fix per gap	Content tools, not gap-linked	Content tools, not gap-linked	No	No	No	One draft asset per scored opportunity

Bundled suites: Semrush AI Toolkit and HubSpot AEO

Both bolt AI visibility onto a platform you are probably already paying for. That is a real advantage: no new vendor, no new login, and the AI numbers sit beside the SEO or pipeline reporting your leadership already reads.

The trade-off is depth. Bundled tools lean toward site-side readiness - is your content crawlable, structured, and answer-shaped - plus a light layer of answer checking. You get a directional signal, not a prompt-level map. If the question is "are we AI-ready?", they answer it. If the question is "which of our 40 buying-stage prompts do we lose, on which assistant, and why?", they do not.

Credit-based trackers: AthenaHQ and Rankscale

Both sell breadth. Rankscale in particular covers more AI engines than anything else in this set, and AthenaHQ goes wide across assistants on a credit allowance. If your buyers are spread across many surfaces, or you work internationally where Copilot and regional engines matter, breadth is the right thing to buy.

Watch the credit math. Each engine query spends credits, so wide coverage plus frequent re-scans drains an allowance faster than the plan price suggests. Model your real prompt count and scan frequency against the included credits before comparing headline prices with a flat-rate tool.

Otterly.ai: the cheapest reporting layer

Otterly.ai has the lowest published entry price in the category at $29/month, with clean brand-coverage charts and competitor leaderboards. For a team whose deliverable is a monthly slide, it is hard to beat on cost per report.

It is a monitoring product. It tells you what happened; deciding what to do and writing the asset is your job. There is no journey-stage view and no drafting engine.

Monroya: share of voice by buyer-journey stage

Monroya measures the same underlying thing - how often you appear and get cited when buyers ask - but reports it as a matrix rather than a percentage. Every tracked prompt carries a stage (discovery, evaluation, decision, retention) and every assistant is a column, so the output is "you hold decision-stage prompts on Claude and vanish at discovery on ChatGPT", not a single blended number.

Citations are grouped by source type - community threads, review sites, reference pages, editorial, analyst, documentation, owned pages - so you can see what kind of source an assistant is leaning on, not just a list of URLs. Each gap becomes a scored opportunity with a drafted asset behind it.

Where Monroya is not the answer: if you need the widest possible engine list, Rankscale covers more. If you need the cheapest shareable dashboard, Otterly.ai wins. If AI visibility is one row in a report you already build in Semrush or HubSpot, the bundled toolkit is the lower-friction choice.

How to pick

Already in Semrush or HubSpot, and AI is a reporting line? Use the bundled toolkit. Revisit when someone asks which stage you are losing.

Need the widest engine coverage? Rankscale, then AthenaHQ. Budget on credits, not the sticker price.

Need a cheap, presentable dashboard? Otterly.ai.

Need to actually move the number this quarter? Monroya - stage-level diagnosis, ranked opportunities, and the draft that closes each one.
