Nexoya connects ChatGPT to a Nexoya workspace so marketers can ask natural-language questions about marketing portfolios, campaign or adset contents, funnel steps, labels, events, performance metrics, daily trends, regression-based attribution, and budget optimization recommendations. The app helps users summarize marketing performance, compare periods and channels, inspect ROI and ROAS, reason about trends, and explain the latest optimization proposal without leaving ChatGPT. Access is scoped to the signed-in user's Nexoya account and team permissions.
