How it works
Enter a comma-separated brand list and a target prompt. The tool simulates per-assistant share of voice for each brand and averages it into a composite. Use the view to benchmark a category or watch a head-to-head race.
Why share of voice
- Raw mention counts are meaningless without a denominator - share of voice normalises for category size and assistant scope.
- A 30% share of voice across all four assistants is the threshold at which you become the default recommendation for most long-tail variations of the prompt.
- Breaking out share per assistant exposes hidden weaknesses - you might dominate ChatGPT and be invisible on Gemini.
