SchemaSketch

SchemaSketch is a web app (with optional desktop agent) that turns real-world datasets into clear, shareable data relationship diagrams and “data story” visuals. Connect a database or upload CSV/Parquet, and it profiles tables, detects keys, joins, and anomalies, then generates an interactive entity-relationship map plus a lineage-style flow chart showing how fields relate and where quality breaks. It’s not a BI dashboard tool; it’s a visualization layer for understanding data structure fast—especially when inheriting a legacy warehouse or integrating acquisitions. The AI assists with naming, grouping, and explaining relationships in plain English, but users can override everything and export to docs, tickets, or diagrams. The MVP focuses on one job: help teams stop guessing how data fits together before they build reports, pipelines, or models.
