AI Share of Voice Calculator

AI share of voice is the part of AI answers, mentions or citations that goes to your brand instead of your competitors. It is counted across a fixed set of buyer questions. GetIntel, an AI visibility tracker, built this calculator to divide your counts three ways: by all brands' mentions (share of voice), by the answers you checked (mention rate) and, if you add them, by first mentions and citations.

Why does the denominator change the answer so much?

Because one AI answer names several brands. GetIntel's AI Software Index holds 9,978 ChatGPT and Gemini answers across 126 software categories, collected for the 6 August 2026 edition. In a median category, the leading brand appeared in 91% of answers but held only 17% of the mentions shared among that category's leaderboard of 9 or 10 brands. No category leader held more than about a quarter. In CRM software, HubSpot appears in 86% of answers, yet its share of voice among the five leading brands is 25%:

Mention rate tells you how often you show up at all. Share of voice tells you how much of the conversation is yours once competitors appear too. First mentions are the closest thing to a recommendation: across the 126 categories, the median category's most-often-first brand was named first in 40% of answers. In a GetIntel test of one brand across 60 prompts and four AI engines (10 July to 10 August 2026), its share of voice came out anywhere from 0.94% to 40% on identical data, depending only on the denominator. That study is in how to measure share of voice in generative engines.

How should you count?

Use a fixed list of buyer questions, the same engines and the same dates for every brand. Count each answer once per brand, however many times it repeats the name. Include every competitor that appears, because the share of voice column only divides among the brands you enter. Then report one number with its denominator beside it, every time. The category leaderboards in the AI Software Index show these rates for 126 categories, and GetIntel's AI visibility tracking collects the counts daily.
