Free statistics calculators, every step shown

Stats Workbench Pro / API (coming soon)

We are planning a paid Pro / API option for people who run the same analyses again and again at work. It is not available yet. If it sounds useful, leave your email below and we will tell you when it opens.

What stays free

Nothing that is free today moves behind Pro:

  • Every calculator on the site, with all of its options, steps and worked examples.
  • Copying results, sharing a link that reopens the calculator with your numbers, and printing or saving the result as PDF.
  • Your data stays in your browser. The free calculators never upload what you type.

What Pro / API would add

  • Whole-file analysis: open a CSV file and run descriptive statistics, tests or regressions on many columns at once, instead of pasting one list at a time.
  • Report export: the results of a session as one formatted document (tables and steps) to attach to a report.
  • A JSON API: the same calculations from your own code or spreadsheet scripts. Each calculator already has a fixed input and output format, so the API would return exactly what the page shows.

There is no price yet and nothing to buy. Joining the list is free and does not commit you to anything.

We will send one email when it opens and will not use your address for anything else; see the privacy policy.
