Open DuckDB Web Shell Why this one
Let an assistant help write a query, then calculate the answer against your file instead of trusting arithmetic in a chat response. The browser engine needs no database server.
Try this first
Import a small made-up CSV. Give an assistant just its column names, ask for a row-count or total query, review the SQL and compare its answer with a few known rows.
How it helps your AI
Use AI for query drafting and DuckDB for the actual calculation. Inspect the query and verify a small example before trusting a result.
