Opal

Opal is a Google-developed AI assistant that helps users analyze, explore, and understand data directly in the browser. It connects to data stored in Google Sheets, CSV files, and other structured sources, then uses natural language queries to generate insights, summaries, and visualizations. Users can ask questions in plain English—such as identifying trends, comparing segments, or checking performance over time—and Opal translates these questions into appropriate data operations without requiring SQL or advanced analytics skills.

Key capabilities include automated chart and table generation, quick descriptive statistics, and guided explanations of what is happening in the data. Opal can highlight outliers, surface notable changes, and suggest additional questions to deepen analysis. It supports iterative exploration, allowing users to refine questions and drill down into specific subsets or dimensions.
