AI visibility tools compared
Updated 5 October 2026
AI visibility tools differ on four things that matter: which assistants they ask, which questions, where the question is asked from, and how often. Prices run from free one-off checks to several hundred dollars a month. Most of the difference in what they report comes from the questions they ask rather than the price.
The four things that actually differ
- Which assistants. Some check one, some check ten. ChatGPT, Perplexity, Gemini and Claude disagree often enough that missing one leaves a real gap.
- Which questions. The biggest driver of the result. A generic category question can make a well-recommended business look invisible — see how to check.
- Where from. Assistants answer for the person asking. A tool asking from the wrong country tests a market you are not in.
- How often. A one-off check is a snapshot. Answers move week to week.

Which to use
You want a free one-off look
HubSpot's grader if you want a brand-perception reading from what the models already know. Ask All Four's free check if you want to see live answers to real customer questions, from a UK location, across all four assistants. Cited's free tier is generous if you will set your own questions.
You are a UK business wanting to know if you are being recommended
The question and the location matter more than the number of engines. Ask All Four drafts the questions from your own website, asks from your location, and includes Claude at the entry price — which Semrush and HubSpot do not cover, and Profound reserves for Enterprise.
You want many engines and many prompts
Cited and Profound cover the most engines, including Google's AI Overviews and AI Mode, which Ask All Four does not. Semrush runs 25 prompts daily. If breadth of tracking is the priority, those are stronger.
You are an agency
Cited's Agency tier and Profound's Enterprise are built for portfolios of clients.
Where Ask All Four is narrower
To be plain about it: Ask All Four checks four assistants, not ten, and does not cover Google AI Overviews or Copilot. It asks three questions, not twenty-five. It runs weekly, not daily. Those are choices — three questions drafted from your own site are worth more to a small business than twenty-five generic ones, and weekly is often enough to catch a change before it costs you — but if you need breadth, the tools above offer more of it.
See what all four say about you.
Three questions your customers actually ask, put to ChatGPT, Perplexity, Gemini and Claude from your location. Free, about twenty seconds, no account.

Which AI visibility tool is best?
The one that asks the questions your customers ask, from where they are. Engine count and prompt volume matter less than whether the questions are the right ones.
Is there a free AI visibility checker?
Yes. HubSpot's AI Search Grader is free and one-off, Cited has a free tier, and Ask All Four's check is free with no account.
Do I need daily tracking?
Most small businesses do not. Answers do move constantly, but the changes worth acting on persist for weeks. Weekly catches them.
Why do different tools give me different scores?
Mostly because they ask different questions. A tool asking a generic category question will usually report lower visibility than one asking what your customers actually type.
