What is share of model (AI share of voice)?
Quick answer: Share of model is the percentage of AI answers about your category that mention or cite your brand versus competitors - your share of voice inside the models. It is the AI-era equivalent of share of search, and it predicts how often AI recommends you when buyers ask.
As buyers research inside ChatGPT, Perplexity and Google AI, being named in the answer is the new ranking. Share of model measures how often that happens for the questions that matter to your business.
You measure it by running your category prompts through the engines and counting mentions and citations for you and each rival, tracked over time. A rising share of model means AI increasingly recommends you.
