Questions about Ask Csv

How does Ask Csv work?

Ask Csv turns CSV files into answers while keeping the data local and private in the browser. It uses DuckDB and on-device AI to interpret questions into SQL, can generate charts from the data, and does not require creating an account.

Is Ask Csv free?

Ask Csv has a free plan, but it is limited to ten successful queries each month and does not support combining or stacking CSV files. The Pro plan costs $5 per month and adds unlimited analyses, exports and no ads.

Does Ask Csv upload data to the cloud?

No. Ask Csv runs all computations locally, so CSV data never leaves the browser and no cloud upload is needed. The trade-off, as the reviewer notes, is that analysis is limited to on-device queries.

What are the downsides of Ask Csv?

Ask Csv requires an initial AI model download of around 1.8GB, which slows the first use, though the model is cached for faster future sessions. The free plan is limited to ten successful queries a month and does not support multi-file operations.

What are some alternatives to Ask Csv?

Toolio lists Awan LLM and AIthenticate as alternatives to Ask Csv. Awan LLM provides unlimited tokens and unrestricted use of large language models for a monthly charge, while AIthenticate focuses on ensuring transparency and compliance.
