A visibility score on its own does not tell you if you are winning. Share of Voice compares your mention rate against your tracked competitors, per engine, so you know exactly where you stand.

Visibility score
0% in Claude
Sample data shown for illustration.
AI share of voice is your portion of all brand mentions across the answers you track. Visibility OS counts every brand named in each response, including competitors you did not add yourself, and reports your share of that total per engine and over time.
Share of voice is calculated from the brands actually named in tracked answers, not from an estimate.
Competitors are discovered from your domain at setup, and you can add or remove any of them.
Share is broken out per assistant, because a brand can lead in one engine and be absent in another.
Period-over-period comparison uses the same prompt set, so a change in share reflects the answers and not a change in method.

Because share differs by assistant
A 40 percent visibility score can be a strong lead or a distant third place. It depends entirely on what your competitors are scoring on the same prompts.
The same prompt often surfaces several brands in one answer. Share of Voice tells you what fraction of those mentions were actually you.
A competitor can be gaining ground on an engine you are not watching closely, and Share of Voice is what surfaces that before it becomes a pattern.
Tracking share over time shows whether a content or PR push actually moved the needle relative to competitors, not just in absolute terms.
Different engines can favor different competitors entirely. Comparing share per engine, not just blended, is what shows you where the real gap is.
Share of Voice is built from the same real checks every other metric uses, nothing separate to set up.
Every check records which competitors from your tracked list were also mentioned in the same answer, alongside you.
Your mention rate and each competitor's mention rate are totaled across your prompt set, per engine and over a trailing window.
Your mentions divided by total mentions across you and your competitors gives a share percentage you can track day over day.
