What Evertune is, and who it is for
From visibility to paid media. Evertune covers four steps: explore what buyers ask, measure visibility, act through content and affiliate partners, and advertise inside and beyond the AI conversation, including ChatGPT ad campaigns.[2]
Deep sampling, real prompts. It samples each prompt up to 100 times per model and grounds its prompt strategy in EverPanel, a panel of over 150 million user prompts.[2]

Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.
