Key Takeaways
- AI visibility tools tell you whether AI engines like ChatGPT, Perplexity, and Google AI Overviews actually mention and cite your site.
- They split into two kinds: off-site monitors that watch the AI answers themselves, and an on-site layer that tracks AI crawlers and referrals hitting your own site.
- Off-site SaaS monitors like Profound and Otterly.ai measure share of voice, brand mentions, and sentiment across many engines, and they are paid.
- The free RankReady plugin is the on-site layer for WordPress: it logs which AI crawlers visit, flags citation candidates, and tracks real AI referral traffic.
- The two are complementary. Most WordPress owners should start with the free on-site layer, then add an off-site monitor when budget allows.
A client called me last quarter convinced their SEO was working. They ranked on page one for their main terms, traffic looked steady, and the dashboards were green. Then a prospect told them, “I asked ChatGPT for the best option and you weren’t on the list.” Nobody on the team could say whether that was true, because nobody was looking. They could see Google. They were blind to everything an AI assistant said about them.
That blind spot is what AI visibility tools exist to fix. As more people ask an assistant instead of scrolling a results page, the question shifts from “where do I rank” to “do the AI engines mention me, and are they citing my pages.” This guide explains what AI visibility tools do, the two very different kinds you will run into, and how a WordPress site can start measuring this without a big budget.
What Is an AI Visibility Tool?
An AI visibility tool measures how present your brand and content are inside AI-generated answers. Instead of tracking a blue-link position, it answers questions like: when someone asks ChatGPT or Perplexity about your category, does your name come up? Which of your pages get cited as sources? How often, and how does that compare to competitors?
This is the measurement half of answer engine optimization. You can do all the right on-page work, but without visibility data you are guessing. The tools turn “I think we show up sometimes” into a number you can track over time.
Two Kinds of AI Visibility Tools
This is the distinction that saves you money and confusion. AI visibility tools fall into two camps that measure different things.
Off-site monitors watch the AI answers themselves. They run prompts across many engines, then report whether you appear, how your share of voice compares to rivals, and what the sentiment is. They see the conversation happening out in the models, which your own analytics never will.
On-site tools live inside your website. They cannot see what ChatGPT says about you, but they can see something just as useful: which AI crawlers actually fetch your pages, which posts those citation-hungry bots return to, and how much real traffic arrives from AI assistants. One watches the answer; the other watches your site.
| Tool | Type | What it watches | Price |
|---|---|---|---|
| Profound | Off-site SaaS | Answers across 9 engines plus AI Overviews: share of voice, citations, sentiment | Demo / freemium, pricing not public |
| Otterly.ai | Off-site SaaS | Brand mentions and citations across ChatGPT, AI Overviews, Perplexity, Gemini, Copilot | From $29/month, free trial |
| RankReady | On-site WordPress plugin | AI crawler hits, citation candidates, real AI referral traffic to your site | Free |

The Tools, and What Each Is Best For
Profound is an off-site platform that tracks your brand across Perplexity, ChatGPT, Claude, Gemini, Grok, Microsoft Copilot, Meta AI, DeepSeek, and Google AI Overviews. Its Answer Engine Insights show how you are represented in AI conversations, alongside prompt volume data, agent analytics for how bots crawl you, brand sentiment, and source citations. It is an external SaaS you log into separately, and pricing is demo-led rather than published. Best for larger brands that need cross-engine share-of-voice and sentiment in one place.
Otterly.ai monitors ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Gemini, and Claude. It combines AI prompt research, search analytics for brand appearance, brand mention and citation tracking, competitor benchmarking, and content auditing to find why AI skips certain pages. It is a paid SaaS with a free trial, starting at $29 per month. Best for small and mid-size teams that want off-site monitoring without an enterprise contract.
RankReady is the on-site layer, a free WordPress plugin rather than an external dashboard. It logs which of the 31 AI crawlers it tracks actually visit your site, flags your posts as citation candidates when citation-focused bots return to them, and reports real AI referral traffic arriving from ChatGPT, Perplexity, Claude, Gemini, and Copilot. It also scores each post against 22 AI-readiness signals so you can fix what is holding a page back. Best for WordPress owners who want to measure crawler and referral reality and improve their pages, for free, on their own site.
What to Actually Track
Whichever tools you pick, a few metrics matter more than the rest. Citations, meaning which of your pages get used as sources, are the closest thing to a ranking in AI search. Share of voice tells you how often you appear versus competitors for the prompts that matter. AI referral traffic is the real visits landing on your site from assistants, the bottom-line proof that visibility converts. And crawler access is the quiet prerequisite: if the AI crawlers cannot reach a page, none of the rest can happen.
Notice that the first two live off-site and the last two live on your own site. That is exactly why the two kinds of tool complement each other rather than compete. A site audit that ignores AI crawler access now leaves a real gap.
How to Start on WordPress
If you run WordPress, start with the on-site layer because it is free and it covers the metrics you own. Install RankReady, let it log AI crawler activity and referrals for a couple of weeks, and use the per-post readiness score to fix your most important pages. That alone tells you whether AI engines can reach and understand you, which is the foundation everything else sits on.
Once you have that baseline and a budget, add an off-site monitor like Otterly.ai or Profound to see how you actually show up in the answers across engines. RankReady is free forever, GPL-2.0, runs on WordPress 6.0+ and PHP 7.4+, keeps zero telemetry, and works alongside Rank Math, Yoast, AIOSEO, and SEOPress, so adding it does not disturb your existing SEO setup.

The Honest Take
No visibility tool earns the citation for you. They are mirrors, not magic. A monitor that tells you a competitor owns the answer is only useful if you then improve the page, the schema, and the depth that made the competitor citable in the first place. Measure first so you stop guessing, but keep the work where it belongs: on content worth quoting.
For most WordPress sites the sensible path is simple. Get the free on-site picture, fix the pages that matter, and add a paid off-site monitor when the stakes justify it. Visibility is the scoreboard. The content is still the game.
