The short answer
How RankX AI and Otterly.ai differ, in one screen.
RankX AI and Otterly.ai both track brand mentions in AI search. Otterly.ai starts at $29 a month for four engines, with Claude, Gemini and Google AI Mode sold as add-ons. RankX AI starts at $49 a month with seven surfaces included, plus Google rank tracking and site audits.
Choose RankX AI if
Claude, Gemini or Grok matter to you, because all three are included rather than sold as add-ons, and you want Google rank tracking, site audits and content publishing on the same plan instead of a separate SEO tool beside your AI tracker.
Choose Otterly.ai if
Budget is the binding constraint or your team is large. Otterly.ai is the cheapest published entry in the category at $29 a month, and every tier carries unlimited team members.
The full price
What do Otterly.ai and RankX AI cost?
RankX AI starts at $49 a month with 3 seats. Otterly.ai's published tiers are below, in their own words.
| Tier | Price | What it covers |
|---|---|---|
| Lite | $29 a month, or $25 billed annually | 15 search prompts and 1,000 GEO URL audits a month |
| Standard | $189 a month | 100 search prompts and 5,000 GEO URL audits a month, with API and MCP access; an extra 100 prompts is $99 a month |
| Premium | $489 a month | 400 search prompts and 10,000 GEO URL audits a month, with API and MCP access; an extra 100 prompts is $99 a month |
| Enterprise | Custom | Starting from 1,000 search prompts, with single sign-on and a dedicated customer success manager |
Every tier includes the same four AI engines, ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, with unlimited team members, and annual billing takes roughly 15 percent off each price.
The line to read carefully is the engine list. Claude, Gemini and Google AI Mode are not in it: they are add-ons, published between $9 and $439 a month depending on the tier and the engine, so the $29 headline and our $49 one are not covering the same ground.
The head to head

What those rows mean in practice
Claude and Gemini are included, not extras
RankX AI tracks ChatGPT, Claude, Gemini, Grok, Perplexity and Microsoft Copilot in AI visibility checks, plus Google AI Overviews, on every plan including the $49 Starter. Otterly.ai includes four engines and sells Claude, Gemini and Google AI Mode as add-ons published from $9 to $439 a month. Compare the coverage you actually need, not the headline price.
A real site audit, not a URL-level GEO check
Otterly.ai publishes GEO URL audits, capped at 1,000 URLs a month on Lite. RankX AI runs a full technical site audit with JavaScript rendering from the Growth plan up, which is a different job: one scores pages for AI readiness, the other finds the crawl, index and performance faults underneath them.
The SEO half is included rather than absent
Otterly.ai is an AI search monitor and does not track Google rankings, research keywords or publish content. RankX AI does all three on the same plan, so a team replacing one subscription is not left buying a second tool for the work the first one surfaced.
The right fit
Where Otterly.ai is the better choice.
Each product suits a different buyer, and the comparison is only useful if it says which. Here is the buyer Otterly.ai suits best.
A lower entry price, and unlimited seats on every tier
At $29 a month, or $25 billed annually, Otterly.ai is the cheapest published entry in the category, and every tier carries unlimited team members. For a large team that needs four engines watched on a small budget, Otterly.ai is built for that brief.
More tracked prompts at the top, and flat prompt top-ups
Otterly.ai publishes 400 search prompts on Premium against 100 per project on RankX AI Pro, and sells another 100 for $99 a month on Standard and Premium. RankX AI funds everything from one credit allowance, so the same budget moves between prompts, rank checks, audits and drafts; a buyer who only ever wants more prompts may prefer a flat top-up.
ChatGPT Ads tracking, and API access from Standard
Otterly.ai publishes ChatGPT Ads tracking on all tiers and API, MCP and Agent Analytics access from Standard upward. RankX AI publishes an MCP server covering visibility, rankings, audits, research and publishing, and reports sponsored product cards inside AI Shopping. Teams whose main question is who advertises on ChatGPT across a whole prompt set will find that report on Otterly.ai.
