AskCSV

AskCSV lets users drop a CSV, TSV, or Excel file into the browser, ask business questions in plain English, and receive calculated answers and charts. The page states that an on-device AI model interprets questions into safe queries, DuckDB runs the query, and AskCSV explains the result. The page states that file data stays in the browser and is not sent to AskCSV servers. Free use includes 10 successful analyses per month without an account; Pro is listed at $5/month with unlimited analyses, exports, and two-file combine. Asking custom questions requires a one-time download of an AI model of 0.9 to 1.8 GB, cached in WebGPU-enabled browsers. The page also suggests verifying the data boundary via browser network inspection, and notes Google and Stripe are used only for Pro.
