The short answer
What share of voice means in AI search.
What is share of voice in AI search?
Share of voice in AI search is your slice of all the brand mentions across a set of AI answers. You run a fixed set of buying questions, count how often each brand is named in the answers, and divide your mentions by the total mentions across every brand. A related number, answer share, is how often you are named as a percentage of the answers checked. Both are reported per engine, because ChatGPT, Perplexity, Claude and Gemini pull from different sources and rarely agree. This calculator does the math on counts you already have; to gather them automatically across five engines, run the AI Visibility Checker.

What you need
Three inputs, one ranked leaderboard.
You supply the counts, from a manual check or the AI Visibility Checker's report. The calculator ranks every brand and marks where you sit.
One number: how many AI answers you read across your prompt set. This is the denominator for answer share.
Add your brand and up to five rivals, with how many of those answers named each one. Mark which brand is yours.
The tool divides each brand's mentions by the total, ranks them, and shows your rank and the gap to the leader in points.

Share of voice is only meaningful against the same prompt set over time. Compare like with like, and measure per engine.
What good looks like
Same prompts, per engine, measured over time.
The number is easy to game and easy to misread. These are the things that make a share-of-voice figure worth trusting.
ChatGPT, Perplexity, Claude and Gemini pull from different sources. A single blended number hides the engine you are losing.
Share of voice only compares over time if the questions stay the same. Change the prompts and you change the number.
Your share only means something next to the brands the engines actually name. Include the ones that keep showing up.
A low percent in a crowded category can still be a strong rank. What matters is who is above you and by how much.
The point of the number is to move it. Re-measure the same set after the work lands, and watch the gap close.

What is share of voice in AI search?
Share of voice is your slice of all the brand mentions across a set of AI answers. You count how often each brand is named across a fixed prompt set and divide your mentions by the total mentions across every brand. It is reported per engine, because the engines pull from different sources and rarely agree.
How do I calculate share of voice for AI answers?
Read a fixed set of AI answers for your category, count how many name each brand, then divide each brand's mentions by the total mentions across all brands. This calculator does that math for you: enter the answers you checked and each brand's mentions, and it ranks every brand and shows your gap to the leader.
What is the difference between share of voice and answer share?
Answer share is how often you are named as a percentage of the answers checked. Share of voice is your mentions as a percentage of all brand mentions across those answers. Answer share tells you how present you are; share of voice tells you how present you are relative to everyone else. This tool shows both.
Is this calculator free?
Yes. It is free, needs no signup, and runs entirely in your browser, so nothing you enter is uploaded. To gather the counts automatically across ChatGPT, Google AI Overviews, Perplexity, Claude and Gemini, run the free AI Visibility Checker.
Where do I get the mention counts?
Two ways. You can read the answers yourself: ask your category's buying questions in each engine and tally who is named. Or run the AI Visibility Checker, which does this across five engines and reports the counts, then bring the numbers here to model scenarios.
What is a good share of voice?
There is no universal number. In a crowded category, being named in one in five answers can be a strong rank. What matters is your rank against the brands answering the same prompts and whether the gap to the leader shrinks after you ship work.
