Stacy's Brain helps marketers and growth teams find research-backed statistics and assess how much confidence to place in them. Search its collection of marketing insights by metric, channel, or question, and check each card’s source and reliability tier. The grading system distinguishes evidence such as peer-reviewed studies, controlled tests, vendor reports, surveys, and opinions, so you can weigh the methods and sample behind a claim before using it in a strategy or presentation. Save useful findings into collections, add notes, and share folders. Stacy’s Brain also connects with Claude to provide marketing figures with their source and reliability context.
