The short answer
How RankX AI and Semrush differ, in one screen.
Semrush is a full SEO and marketing suite that also sells its AI Visibility Toolkit alone, from $99 a month per domain billed annually, with extra users from $45 a month. RankX AI is an AI visibility and SEO platform from $49 a month with three seats included. Semrush suits teams that need its full keyword and backlink suite.
Choose RankX AI if
AI visibility is the job and you want it without buying a suite, or more than one person needs access. RankX AI includes three seats at the entry tier, where Semrush charges from $45 a month for each user beyond the first on plans that start at $117.33.
Choose Semrush if
You need a full SEO and advertising suite. The Semrush keyword database, backlink index, competitor and advertising research, and 500 to 5,000 daily tracked keywords are built for teams whose work centres on classic SEO and paid search. RankX AI is built for AI visibility and the fixes behind it, without the suite.

The head to head
Which product wins on which criterion?
Figures come from Semrush's published pages, read 1 October 2026. Every row names the product it favours.
| Criterion | RankX AI | Semrush | Favours |
|---|---|---|---|
| Entry price for AI search tracking | $49 a month | $99 a month per domain billed annually for the AI Visibility Toolkit, or $165.17 inside the SEO suite | RankX AI |

| AI prompts tracked | 25 to 100 per project by plan, daily to monthly per prompt | 25 a day on the AI Visibility Toolkit; 50, 100 or 200 a day on the suite plans | Semrush |
| Google keywords tracked | 100 to 1,000 by plan | 500 to 5,000 daily | Semrush |

What those rows mean in practice
Seats are included rather than charged for
Semrush publishes additional users from $45 a month. RankX AI includes three seats on the $49 Starter, ten on Growth and 25 on Pro. A three-person team is one invoice on RankX AI and, on Semrush's published rates, the base plan plus two user fees.
Every assistant is named, and there are seven surfaces
RankX AI publishes exactly which surfaces it watches: ChatGPT, Claude, Gemini, Grok, Perplexity and Microsoft Copilot in its prompt checks, plus Google AI Overviews on your tracked keywords. Semrush's AI Visibility Toolkit pricing names four, ChatGPT, Google AI, Gemini and Perplexity, and its suite plans list more without naming them.
You are not buying a suite to get the AI half
Semrush's AI search tracking sits inside a marketing platform priced from $117.33 a month billed annually. If AI visibility, rank tracking and site audits are the whole job, RankX AI does that job from $49 without the advertising research, PPC tooling and social features you would not open.
The right fit
Where Semrush is the better choice.
Each product suits a different buyer, and the comparison is only useful if it says which. Here is the buyer Semrush suits best.
The Semrush SEO dataset is its core product
Its keyword database, backlink index and competitive research are among the largest available and have been built over many years. RankX AI is built for AI visibility, rankings and site fixes rather than link research, so for link building or competitor backlink analysis, Semrush is the tool for that job.
Far more tracked keywords, and daily AI prompt checks
Semrush tracks 500 daily keywords at entry and 5,000 on Advanced, and its suite plans track 50, 100 and 200 AI prompts a day. RankX AI tracks 100 to 1,000 keywords by plan and runs each prompt on the schedule you set. Teams that need that raw tracking volume at those tiers are the Semrush buyer.
It is the tool your team already knows
Semrush is the default in most SEO teams, with training, integrations and a hiring pool built around it. A team that already runs Semrush well can add its AI Visibility Toolkit and judge whether the prompt allowance covers the job, or run RankX AI beside it for the AI half.

Questions
Semrush, answered
The questions people ask before choosing between RankX AI and Semrush.
Does Semrush track AI visibility?
Yes, two ways. Semrush sells an AI Visibility Toolkit on its own, from $99 a month per domain billed annually with 25 prompts tracked daily, and includes AI visibility tracking in its SEO + AI Search plans at 50, 100 or 200 prompts a day. The toolkit's pricing page names mentions from ChatGPT, Google AI, Gemini and Perplexity. Read on 1 October 2026.
Is RankX AI a replacement for Semrush?
For AI visibility, rank tracking, site audits and publishing, yes, with three seats included from $49. For deep keyword and backlink research, the Semrush suite is built for that job, because RankX AI focuses on AI answers, rankings and the fixes behind them. Many teams run both.
Which is cheaper for a small team?
RankX AI, on published rates. Semrush's AI Visibility Toolkit is $99 a month per domain billed annually, its SEO plans start at $117.33 billed annually with one user, and additional users start at $45 a month. RankX AI's Starter is $49 a month with three seats included, and Growth is $99 with ten.
Can I use both?
Yes, and many teams do. Semrush covers the keyword and backlink research, and RankX AI covers the six assistants and Google AI Overviews by name, with a published MCP server so your own AI assistant can query the data directly.
