Conversational query

Ask a question in plain language. Sema classifies intent, plans SQL grounded in your glossary and verified joins, runs it read-only against your warehouse, and auto-charts the result.

What you see

• A streamed answer with an auto-selected chart (bar / line / stat / map).
• A plan inspector — the SQL, tables, joins, assumptions and a confidence score.
• Follow-up actions — Save as report, Watch as alert, Promote to signal.
