AskCSV

AskCSV is a browser based CSV analyzer that answers questions about your data in plain English. You drop in a CSV or TSV file, ask something like which products drive the most profit or what changed from April to June, and it returns a calculated result along with a table or chart. The language model runs on your own device, turns your question into a query, and DuckDB executes that query locally, so the file contents are not sent to AskCSV servers. It suits analysts, operators and small business owners who want quick answers from exported spreadsheets without building pivot tables, and anyone who needs to keep sensitive data on their own machine. Conversations and files stay in the browser until you delete them, and the site explains how to inspect network requests to verify that claim. The first use downloads an AI model of roughly 1.8 GB, and a WebGPU enabled browser is required to run it. The Free plan costs $0 and includes 10 successful analyses per month, one CSV at a time, with files, chats, print and dark mode, and no account is needed. Failed attempts do not count against the limit. The Pro plan costs $5 per month and adds unlimited successful analyses, export of ZIP bundles and chart PNGs, a deterministic two file join or stack, and an ad free app. Pro requires Google sign in and payment through Stripe, and you can cancel at any time.
