Which AI visibility modules are sold on their own: five platforms compared, and the three where your prompt allowance is set by your SEO spend

Of five platforms that sell an AI visibility module, read on their own pages on 20 October 2026, two state plainly that the module can be bought on its own and three sell it only inside a subscription you are buying for other reasons. SE Ranking's FAQ says SE Visible is available standalone, independent of an SE Ranking subscription. HubSpot's page says its AEO product needs no HubSpot subscription. Ahrefs says Brand Radar's custom prompts are "Free for every paid Ahrefs Lite plan and above", so you have to be an Ahrefs customer first. Frase sells AI Visibility as a feature of its content plans, and Semrush sells its AI work as modules inside the SEO and AI Search ladder. That split matters more than any feature table, because in the three bundled cases the number of questions you may track is chained to a limit about keywords, backlinks or articles.

The one question, and the five published answers

Platform, read 20 Oct 2026	Can the AI module be bought on its own	What the AI allowance is chained to	Engines the module names
SE Ranking, as SE Visible	Yes. Its own FAQ states it is available standalone	Prompts tracked daily, a line of its own on the plan table	Google AI Overviews, AI Mode, ChatGPT, Gemini in its product navigation
HubSpot, as AEO	Yes. Its page states no HubSpot subscription is required	A single flat monthly rate, also folded into two Marketing Hub tiers	ChatGPT, Perplexity, Gemini
Ahrefs, as Brand Radar	No. Custom prompts are free for every paid Ahrefs Lite plan and above	Which Ahrefs plan you hold: a daily custom prompt quota of 5, 10 or 20	Six platforms in the index, plus Claude through custom prompts
Frase, as AI Visibility	No. It is a feature of the content plans	The content tier, which also sets articles a month and audit pages	Two at entry, three on the next tier, five on the one above
Semrush, as its AI modules	No. Sold inside the SEO and AI Search ladder	A tier whose AI prompt line rises only when websites and keywords rise	Named per module on its own pages

Why a chained allowance costs more than it looks

Take Ahrefs, which publishes the clearest arithmetic in this group. Its page states that "Each prompt uses 1 check per platform, location and update" and that "Claude consumes 8 checks per update", and the included daily custom prompt quota is 5, 10 or 20 depending on which Ahrefs plan you hold. So the number of buying questions you may watch is a function of how much backlink and keyword tooling you bought, and if the engine you care about is Claude, one platform spends your allowance eight times quicker than the others.

None of that is a criticism of the product, and the bundling is generous rather than mean: the prompts are included in a subscription you were already paying. The point is narrower. A buyer who needs forty questions watched daily across four engines is making a decision about an Ahrefs plan, not about an AI visibility plan, and those two decisions have different right answers.

Frase's version of the same chain is the engine list. Read on 20 October 2026, its AI Visibility tracks two engines on the entry tier, three on the next and five on the one above, while the same steps move articles a month from 10 to 40 to 100, so a buyer who wants Claude read is buying a hundred articles a month to get it. Semrush's version, from our own audit of its ladder published earlier today, is that the AI prompt line rises only when the website and keyword allowances rise with it.

What standalone actually buys you, and what it does not

Unbundled is not automatically the better purchase. Three things are genuinely easier when the AI module is sold on its own. You can size it to your question list, usually twenty to sixty questions for one product in one market, instead of to a keyword ceiling. You can cancel it without losing anything else, because a separate invoice gets reviewed and a line inside a suite stops being noticed. And you can run it beside the suite you already have, which is the only way to see that two readings of one brand disagree because the question lists differ.

And two things are better bundled. The monthly report assembles itself when the AI numbers sit in the same account as the organic keywords, and one invoice and one login is a real saving for a small team. If your AI answers are a secondary curiosity rather than a pipeline question, the module you already pay for is the right answer, and this page is a reason to go and read its current prompt line rather than to buy anything.

The deeper reason the two readings differ is where the questions come from, which is set out in a rank tracker versus an AI visibility tool. That page had no durable inbound link from any body on this site when we counted on 20 October 2026: 3,456 internal links across 2,050 stored bodies against 1,960 live pages, with 911 pages, 46.5 per cent, carrying none.

Where these platforms beat us on this exact question

We sell a single purpose product in this category, so unbundling is the trivial yes for us and it would be dishonest to score ourselves first on a criterion we cannot fail. Here is where we lose instead.

• Our own cheapest plan is bundled the same way. Read on our pricing page on 20 October 2026, the entry plan at the bottom of our ladder is a writing plan with no AI app checks in it at all, and the cheapest plan that watches AI apps is two steps up. We are pointing at a packaging habit we have too.
• SE Ranking publishes a free logged out check with a stated daily limit of 5 attempts, an AI visibility API among seven named APIs, and MCP skills for Claude. We document no MCP endpoint.
• Ahrefs publishes the unit arithmetic in full, the Claude multiplier included, so a buyer can compute next month's consumption before a sales call. We publish our unit and no checks per engine formula beside it.
• Frase publishes SOC 2 Type II, GDPR, SSO and SAML. Our pricing page carries none of those four lines and publishes one full access login per plan.
• Four of the five publish history depth or an export route by tier. We publish no history depth at all.

How to settle it for your own case in twenty minutes

1. Write your buying questions, with your own company name absent from every one. Count them, then multiply by the engines you need and the cadence you want. That is your unit demand, and it is the only number that makes two quotes comparable.
2. Open the AI module inside whatever suite you already pay for and read its current allowance line. Not the feature tick, the number.
3. If the number fits, you are finished and you have spent nothing. If it does not, ask whether that suite will sell you more of the AI half without more of the other half. Two of the five above say yes in writing.

Questions buyers ask about buying the AI module separately

Can I buy SE Visible without SE Ranking?

Its own FAQ says yes, that SE Visible is available standalone and independent of an SE Ranking subscription. The wider platform is reviewed separately in our SE Ranking review, which sets out the six limits that define each self serve tier.

Is Ahrefs Brand Radar free?

Its custom prompts are included in a paid Ahrefs plan rather than free on their own, with a daily quota of 5, 10 or 20 by plan and larger check based packages sold on top. The two detailed comparisons on this site are Peec AI versus Ahrefs Brand Radar and Otterly.AI versus Ahrefs Brand Radar, and both go through the metering in detail.

Is SE Ranking good for AI visibility, or do I need something dedicated?

It is good for it, and the honest test is your prompt count against the prompts tracked daily line on the tier you would buy. Because the AI side is sold standalone, you can also take the AI half and leave the SEO half, which is the route a team with an existing rank tracker usually wants.

What should I ask a suite vendor before upgrading for the AI module?

What the current prompt or check allowance is on the tier I would move to, what happens to the history behind a question when I edit its wording, and which engines sit on that tier by name. The third changes most often.

Which is cheaper overall?

Neither, consistently. A bundled module is cheaper when your question list is short, because you are already paying for the subscription. A standalone product is cheaper when your question list is long, because you are not buying keyword and article capacity to reach it. Compute your unit demand first and the arithmetic answers itself.

Three bundled platforms, three differently shaped bills for the same need

The thing this comparison makes visible is that three buyers with identical AI requirements end up owning three unrelated products. The one at Ahrefs is buying a platform tier, because the daily custom prompt quota of 5, 10 or 20 is attached to it. The one at Frase is buying a hundred articles a month, because that is the tier where Claude and Gemini appear. The one at Semrush is buying websites and tracked keywords, because its AI prompt line rises only with them. None of the three wanted any of that, and all three will be renewing it for years. The standalone route at SE Ranking and HubSpot avoids that by letting the AI number be the thing you are actually buying, and the cost of taking it is a second login and a second report to assemble. That is the whole trade, and it is a packaging decision you make once and live inside for a long time.
