Key takeaways
- Several measurement tools let you enter competitors and compare your brand with them on Gemini and Perplexity. Choose by four things: which assistants the tool covers, how competitors are entered, how often answers are collected, and how results are split by assistant.
- Read Gemini and Perplexity as two separate series. They often cite different sources for the same question, so one combined figure hides what each is doing.
- A tool measures; people do the work that changes the answers. If you would rather have the measurement run for you, the Snapshot sets your brand against three competitors.
Yes, tools for this exist. Several let you enter your competitors and compare your brand with them on Gemini and Perplexity answers, and this guide describes five of them from their own pages. The job here is to choose one that fits your buyer questions and to set it up so the comparison means something.
This guide does a different job from How to find out whether AI assistants recommend your competitors instead of you. That guide is the method: write the questions, ask every assistant more than once, record who is named and cited, and read the rate. This one is about picking and setting up a tool to do the counting for Gemini and Perplexity in particular.
What a comparison on Gemini and Perplexity measures
A comparison tool asks an assistant your buyer questions, reads each answer and counts how often each named company appears. The result is a rate for you and a rate for each competitor, for example named in 9 of 20 answers against 14 of 20. Two things make Gemini and Perplexity worth reading side by side rather than as one figure.
First, the two assistants answer from different places. In our own measurement, Gemini and Perplexity often cite different sources for the same question, so a competitor can be strong on one and absent from the other. Keep each assistant as its own series, and never add or average them.
Second, what you can see behind an answer differs. Perplexity shows the pages it cites. In our own collection of Gemini answers we can see which site a source sits on, but not always which page. A tool that reports pages cited by Gemini is worth a question about how it knows; a tool that reports sites is describing what is available. Mention, citation and recommendation explains why a mention and a citation are counted apart.
Four things to check before you choose a tool
1. Which assistants it covers. Look for Gemini and Perplexity named on the tool's own page, not only "major AI platforms". Check what Gemini means to that tool: the Gemini app, Google's AI Mode and AI Overviews are different surfaces, and some tools list them separately.
2. How competitors are entered. Some tools ask you to list them. Some also suggest competitors from the answers they collect. A suggested list can surface a company you had not thought of, and a typed list keeps the comparison stable from one month to the next. The best fit is a tool that lets you do both and then freeze the list you report against.
3. How often answers are collected, and from where. Answers change from run to run, so repeated collection gives a steadier rate than one pass. Ask whether collection is daily, weekly or monthly, and whether the tool reads the consumer website or an interface for developers, because the two can differ.
4. How results are shown. You want results split by assistant, by question and by competitor, with mentions and citations kept apart, and an export so you keep your own record. A single score with no split cannot tell you whether the gap is on Gemini or on Perplexity.
Setting up a comparison that holds over time
Start with three to five competitors you actually meet in deals, not the longest list you can build. Use the same buyer questions for every company, including questions that name no vendor, because those are where a shortlist forms. Building a buyer-question set covers how to write and freeze the list.
Freeze the question list and the competitor list before the first run. A figure only compares across months if both stay the same, and a change to either starts a new series. Then run the same set at least monthly and write down the date of each run.
If your main interest is Google's own surfaces, measuring visibility in AI Overviews and Gemini covers what Google's reports can and cannot show.
Tools that compare brands on Gemini and Perplexity
The lines below say only what each company's own page says it offers. They are listed in alphabetical order, not ranked, and nothing here says one is better than another. Each carries the date its page was last checked. Prices and plan limits change often, so they are left to each company's own pricing page.
Ahrefs Brand RadarMeasurement tool

Tools measure. The work that changes the answers is done by people, in your team or at an agency, and some teams pair the two.
The managed option: Answer Position
Answer Position is one option among these, and a different kind. It is a service we run, not software you log into. We ask the assistants your buyer questions, count who is named and cited, and give you a report.
The Snapshot is the fixed, one-off version: 30 to 50 buyer questions across three AI assistants, set against three competitors, with a standard report and a 30-minute walkthrough, at £995. The assistants are agreed before work begins, so say at the start if Gemini and Perplexity matter most to you.
The Monitor keeps the same set under watch: 50 buyer questions tracked every month, a monthly report with the five actions that matter most, and a call each quarter, at £595 a month, minimum 3 months. The work the report recommends stays with your team.
A free diagnostic looks at one question first, and the services page shows what each step includes.
What to do first
Write ten buyer questions and pick three competitors. Ask each question three times on Gemini and three times on Perplexity, and record, for each answer, which of the four companies is named and which sources are cited. That is sixty answers and an afternoon of work. It tells you whether a gap exists on one assistant, on both, or on neither, and it shows which of the four checks above matters most for the tool you need.
