Every tool in this category measures roughly the same thing — how often assistants name your brand. What separates them is how many questions and assistants you get for the money, and whether anything helps you change the number afterwards.

Three things are worth knowing before you pick one.
Profound's $99 plan watches ChatGPT and nothing else. The moment you want to know what Perplexity or Google's AI Overviews say about you — which is the whole point for most buyers — you are on the $399 plan. Semrush's $99 covers 25 prompts and charges $60 for each additional 50. Read the engine count and the prompt count together; on their own, both mislead.
Twenty-five prompts sounds like plenty until you write them out. A single category needs the "best", "cheapest", "for small teams", "alternative to", "compared to" and "what do people complain about" variants before the number means anything, and one run of that is a dozen prompts. Measuring a handful of questions once a month tells you very little, because assistants are non-deterministic and the same question returns different names on different days.
This is the real gap. Every tool on that list will tell you that you are named in 30% of answers and that a competitor is named in 70%. Only Profound's $399 tier bundles anything that changes it — six articles a month — and that is the most expensive mainstream plan in the category. Everywhere else, the dashboard is the product and the work is yours, or your agency's at $2,000–5,000 a month.
Work backwards from what you will do with the number.
If you just want to know where you stand, run a one-off audit rather than starting a subscription. Nothing changes week to week at first, and a single measurement across a dozen questions and two assistants tells you as much as a month of daily charts.
If you have a content team already, buy measurement and feed the gaps to your writers. A $29–99 tool plus people who can act on it beats an expensive tool nobody reads.
If you do not have anyone to do the writing, a measurement-only subscription will sit there telling you the same bad news every week. That is the case where paying for the work makes more sense than paying for the chart.
Whatever you buy, make sure it separates these, because they are different problems with different fixes:
Mention rate — how often your brand name appears in the answer. Citation rate — how often the assistant actually links to your site as a source. We audited Ghost as a test and found it named in 91.7% of answers while ghost.org was cited in only 12.5%. The assistants talked about Ghost constantly, using Substack, Wix and WordPress pages to do it. A tool reporting one blended "visibility score" hides exactly that.
