What QueryZy is

A tool for people who have a data file and a question but no interest in query syntax. You drag in a CSV, JSON, Arrow or Parquet file, ask in plain language, and get answers, charts and exports.

The stated design keeps files on your own computer, which matters when the data cannot be uploaded elsewhere.

What you can do with it

  • Import data by drag and drop or URL
  • Ask questions in plain language
  • Plot results as charts
  • Export result tables and charts
  • Work with large datasets
  • Get prompt suggestions while exploring

Who it is for

  • Business users who avoid SQL and pivot tables
  • Analysts doing a quick first look at a file
  • Anyone with data they cannot upload to a cloud service
  • Small teams without a data stack

What to watch out for

  • Verify the claim that files stay local before uploading anything sensitive
  • AI-generated queries need checking against the actual data
  • It is exploration, not a governed reporting layer
  • Confirm what the free trial includes and what happens after it ends

Pros & cons

  • No query language needed

FAQ

What files does it read?

CSV, JSON, Arrow and Parquet files, imported by drag and drop or from a URL.

Does my data leave my computer?

The stated design keeps files on your machine, but verify the current behaviour before uploading sensitive data.

Do I need to know SQL?

No. Questions are asked in natural language.
