A bolt-on AI module inside an SEO suite inherits that suite’s data model, which is built around rankings. Purpose-built trackers model answers instead, and the two produce different numbers for the same brand.
The practical question is not which is better. It is whether you already pay Semrush, because that changes the arithmetic more than any feature does.
What is actually being compared?
Semrush’s AI visibility product is the AI Visibility Toolkit, sold as an add-on to an SEO subscription rather than on its own. Rivarise is a standalone tracker. That difference in shape drives most of what follows.
| Rivarise | Semrush AI Visibility Toolkit | |
|---|---|---|
| Sold as | Standalone product | Add-on to an SEO plan, or bundled in Semrush One |
| Entry price | $69/mo | $99/mo per domain, billed annually, plus the SEO plan |
| Cheapest realistic total | $69/mo | Bundled from $165.17/mo billed annually |
| Prompts at entry | 30 per day | 25 tracked prompts |
| More prompts | Higher tier: 50, 100, 250 per day | +50 prompts for $60/mo |
| Engines | 4 at $69, 9 at $349 | ChatGPT, Google AI, Gemini and Perplexity |
| Refresh | 5 runs per prompt per engine per day | Prompt tracking updated daily; Brand Performance weekly |
| Free plan | Yes, permanent, no card | No free trial for the toolkit |
| Extra seats | Included from Growth up | From $45/mo per additional user |
The row worth reading twice is the third. The $99 headline is not the price of tracking AI visibility with Semrush; it is the price of adding it to a subscription you also have to hold. Their own bundle, which includes both, starts at $165.17 a month billed annually.
What does “inherits the data model” actually mean?
It sounds like an abstraction and it has concrete consequences.
An SEO suite is built around a domain, a keyword, and a position. Those three objects run through everything: the database, the reports, the exports, the mental model of the people who built it. When AI visibility arrives as a module, it lands in that structure, and the natural way to express it is as a domain’s performance against a set of prompts, tracked over time, in a shape that looks like rank tracking.
A purpose-built tracker starts from the answer instead. The primary object is an answer: its full text, the brands it named, the order it named them in, the sources it cited. Position is not a field, because an answer has no positions.
Familiar, easy to report to anyone who has used rank tracking, and it quietly implies a scoreboard the format does not have.
Less familiar, harder to summarise in one number, and it preserves the thing you will want in three months: what was actually said.
Where is Semrush genuinely the better choice?
Three situations, and the first is common enough that it decides most of these evaluations.
The marginal cost of adding AI visibility is $99 rather than a new vendor, a new contract and a new login. That is a real advantage and we cannot match it.
Search and AI visibility in the same interface, exported together, presented to the same stakeholder. Genuinely easier than reconciling two tools.
Site audit, backlinks, keyword research and AI readiness in one place. Buying us as well means paying for two things that overlap.
Where is Rivarise better?
$69 against a bundle starting at $165.17. If AI visibility is the only thing you want, you should not have to buy an SEO suite to get it.
Five runs per prompt per engine per day, stated. “Updated daily” does not tell you how many times a prompt was asked, and that number decides whether a rate means anything.
Nine engines including Grok, DeepSeek and Meta AI. Their toolkit names ChatGPT, Google AI, Gemini and Perplexity.
Kept for your plan’s history window, so you can go back and ask a question of old data that you had not thought of at the time.
Does either cover the engines that matter?
Both cover the ones that publish how they work, which is the set most B2B buyers actually use.
Semrush’s toolkit names ChatGPT, Google AI, Gemini and Perplexity. Those span two retrieval families: OpenAI and Perplexity run their own crawlers and indexes, while Google’s surfaces are grounded in the Search index with “no additional requirements to appear in AI Overviews or AI Mode” beyond ordinary eligibility. That is a defensible core.
Where we go further is at the edges: Claude, Grok, DeepSeek and Meta AI at the top tier. Whether those matter is a question about your buyers rather than about either product. Four engines covering where your market actually is beats nine covering places it is not, and we would rather say that than sell you a number.
Do the two produce different numbers?
They will, and the difference is not a bug in either.
Two tools sampling the same prompt at different frequencies, across different engine sets, will report different visibility for the same brand on the same day. A tool asking once a day and one asking five times will disagree, and neither is lying. The variance is real: ask the same engine the same question repeatedly and the named brands move.
If you run both, expect them to disagree. The useful question is not which is right, it is which one told you how it got its number.
What about prompt volume?
The units are different enough that a like-for-like comparison needs care.
Semrush’s base toolkit includes 25 tracked prompts, expandable by 50 for $60 a month. Rivarise’s Starter includes 50 prompts a day, and higher tiers reach 75 and 80. A “tracked prompt” and a “prompt per day” are not the same unit, and the multiplier between them is the run frequency, which is exactly the number that is published on one side and not the other.
The safe way to compare is to decide how many distinct questions you need to watch, then ask both vendors how many times each of those questions is asked per engine per day. One of the two answers is on a pricing page.
Twenty-five prompts is also worth examining on its own terms rather than as a number to beat. For a single product in one category it is workable, particularly if the prompts are chosen carefully. It becomes tight the moment you want to cover several buyer personas, more than one geography, or a second product line, and the expansion pack at $60 for fifty more prompts is priced such that a serious prompt set moves the total meaningfully.
What do buyers usually ask about the two?
If you want the wider category rather than this one comparison, the twelve-tool roundup covers every option with dated, linked pricing, and it groups them by shape so the bolt-on versus purpose-built distinction is easier to see across the whole market.
