PubSpy is a website research and AdSense discovery platform built around a Chrome extension and a private case-study workspace. It helps users examine a live website by collecting visible page evidence, such as headings, calls to action, pricing signals, links, structure, and colors, then organizing that material into a consistent 30-section analysis. Reports cover products, target users, business models, growth opportunities, risks, differentiation, and possible MVP plans, with public-web research and sources used to distinguish observed facts from estimates, hypotheses, and unknowns. Users can ask follow-up questions, save case studies, and export reports in several file formats.

PubSpy also provides publisher-ID and related-domain lookup, ads.txt checks, domain registration dates, traffic signals, CSV workflows, and link extraction. Its publisher dashboard shows domains associated with synced AdSense IDs, while noting that incomplete coverage is not proof of no relationship. Free, account-free AdSense tools offer guidance on approval readiness, eligibility, and ban risks without guaranteeing Google decisions.
