Converts natural language questions into executable SQL queries by first inferring the schema structure from uploaded data files, then mapping user intent to appropriate SQL operations. Uses LLM-based semantic understanding to handle ambiguous column references, implicit joins, and aggregation requests without requiring users to write SQL syntax. The system maintains a schema cache per dataset to enable multi-turn conversations without re-parsing.

Automatically computes descriptive statistics, distributions, correlations, and runs appropriate statistical tests (t-tests, chi-square, ANOVA) based on data types and user questions. The system detects variable types (continuous vs categorical) and selects test families accordingly, then surfaces p-values, confidence intervals, and effect sizes with plain-language interpretation. Results are cached per dataset to enable rapid re-analysis.

Analyzes query results and data characteristics to automatically recommend and generate appropriate visualizations (bar charts, line plots, scatter plots, heatmaps, etc.). Uses heuristics based on data dimensionality, cardinality, and temporal properties to select chart types, then renders interactive visualizations using a client-side charting library. Users can override recommendations or request specific chart types via natural language.

Accepts data from multiple sources (CSV, Excel, JSON, Google Sheets, SQL databases) and normalizes them into a unified tabular format for analysis. Handles format detection, encoding inference, delimiter detection for CSVs, sheet selection for Excel files, and connection string parsing for databases. Data is loaded into an in-memory or cloud-backed data store with schema caching to enable fast re-analysis without re-parsing.

Maintains conversation history and dataset context across multiple turns, allowing users to ask follow-up questions that reference previous results without re-specifying the dataset or context. The system tracks which columns were used, what filters were applied, and what visualizations were generated, enabling natural dialogue like 'show me the same chart but for Q2' or 'drill down into the top 5 categories'. Context is stored per session with automatic expiration.

Generates structured reports containing analysis results, visualizations, statistical summaries, and interpretations, then exports them as markdown, PDF, or HTML documents. The system organizes results hierarchically (overview → detailed findings → supporting visualizations), includes auto-generated captions and interpretations, and allows users to customize report structure via natural language prompts. Reports are reproducible — they include the original questions and can be re-run on updated data.

Automatically scans uploaded datasets for data quality issues (missing values, duplicates, outliers, type inconsistencies) and flags anomalies using statistical methods (z-score, IQR, isolation forests). Generates a quality report showing issue prevalence, affected rows, and recommended remediation steps. Users can filter or exclude flagged rows before analysis, or request automatic imputation for missing values.

Allows users to filter and segment data using natural language expressions (e.g., 'show me sales over $1000 in Q3' or 'segment by region and revenue tier') without writing SQL WHERE clauses. The system parses natural language conditions, maps them to appropriate column filters, and applies them to the dataset. Supports complex filters with AND/OR logic, date ranges, numeric comparisons, and categorical matching. Filters are composable and can be combined across multiple turns.

Detects temporal patterns in time-series data and generates forecasts for future periods. The system likely identifies timestamp columns, aggregates data by time granularity (daily, monthly, yearly), applies statistical forecasting models (ARIMA, exponential smoothing, or simple trend extrapolation), and visualizes historical data with confidence-interval forecasts. May include seasonality detection and trend decomposition.

Generates plain-English explanations of query results, statistical findings, and visualizations, translating technical outputs into business-friendly language. The system uses an LLM to interpret numeric results, statistical significance, and chart patterns, then produces narrative explanations suitable for non-technical stakeholders. Explanations include context about what the numbers mean and why they matter.
