LLM visibility checker: does ChatGPT, Gemini, Perplexity or Google's AI Overview recommend your brand?

How often, and how early, AI assistants such as ChatGPT, Gemini and Perplexity name your brand when someone asks for a recommendation in your category, and which sources they rely on. It is measured on answers, not on rankings: in the example, Brooklinen was named in 16 of 18 category answers but first in only 8.

Ask the same buyer questions on a fixed schedule and count the brands each answer names. Run this check once, then ask Nolyn in the same conversation to repeat it every week: it becomes a weekly scheduled task that asks the same 8 questions to ChatGPT, Gemini, Perplexity and Google's AI Overview, so changes in your mentions show up week to week. Each weekly run uses credits like a manual one.

A check of what AI answer engines say about your brand and category: whether you are named, against whom, with what verdict, and which sites the answers cite. This tool runs a small, repeatable one: 8 fixed questions on 4 engines, with every share shown with its count, the sources listed by domain and 3 to 5 gaps with actions.

Yes, as one of the four engines. Google shows an AI Overview for some searches and not others, and that changes too: in the example, 6 of 8 questions had one. A question without an overview is reported as “no AI Overview shown”, which is itself worth tracking week to week.

AI answers are generated fresh, depend on the web results the engine pulls that moment, and differ by location and account. Two runs an hour apart in the example disagreed on several brands: Gemini named Brooklinen in 3 of 5 category answers in one and 5 of 5 in the other. That is why the check asks fixed questions and is best read as a weekly trend, not a single score.

Start from what the answers cite. If an engine leans on a few review lists (Perplexity cited goodhousekeeping.com in 7 of 8 answers in the example), being in those lists matters more than your own blog. Make the claims the answers repeat about you easy to verify on your own pages, and check whether your site is cited at all; the gaps in each report name the lists and claims to work on.

No, the default check asks the engines live. Services that estimate brand mentions across large prompt sets exist (for example DataForSEO's LLM mentions data); Nolyn can query them on request, but each lookup costs about 20 credits and covers fewer engines, so they are not part of this check.

Reading this page and the example is free. Running a check needs a Nolyn account: sign in with Google and new accounts get 100 one-time free credits, no card. The example used 57 credits, so one check fits in the free credits; a weekly check uses credits each week.

Yes. Add your city and the category questions become “best med spas in Austin, TX” and so on. The engines are still asked from the United States without a precise location, so answers can differ from what a phone in your city shows.

Reading this page and the example is free. Running a check needs a Nolyn account: sign in with Google and new accounts get 100 one-time free credits, no card. The example run used 57 credits and about 22 minutes (39 for the 32 answers, 18 for the analysis), so it fits in the free credits; four runs of the brief that day used 55 to 68. A weekly check uses credits each week, the same as a manual run.

To run it, yes: sign in with Google. It is free and asks for no card. You can read the example and fill in the form before signing in.
