Official app preview
What it is
JASP is free statistics software for students and researchers. You open a spreadsheet, click the analysis you want, and the results update as you change options, with no programming. JASP says it is "a free cross-platform software program with a state-of-the-art graphical user interface" and "an open-source project supported by the University of Amsterdam". Its GitHub page says it is aimed at people used to SPSS. It was named in honour of the statistician Sir Harold Jeffreys.
Is it free?
Yes. The download page says "Entirely for free, no strings attached", and that JASP is released under the GNU Affero GPL v3 licence, "which guarantees that JASP will always be (for) free". The FAQ describes two parts under slightly different open-source licences (GPLv2 for the analysis engine and AGPL v3 for the desktop app).
What you can do with it
- Run standard analyses by clicking: JASP lists classical (frequentist) and Bayesian versions of standard analyses.
- Live results: it says all results update dynamically, with a spreadsheet layout and drag-and-drop interface.
- Open your files: CSV, Excel, SPSS, SAS, Stata, R data and Minitab files, per the FAQ.
- Copy to Word: it supports APA format and lets you copy graphs and tables into Word.
- Works offline: the download page says no internet connection is needed to run JASP.
- Where: Windows, macOS, Linux and ChromeOS, per the download page. The Windows version is also in the Microsoft Store.
What to watch out for
- It is a large install. The download page says about 4 GB of free disk space and at least 4 GB of memory, with 8 GB recommended.
- Newer systems only. It needs a 64-bit system and does not support 32-bit-only systems. For Windows it lists Windows 10 22H2 and certain Windows 11 versions.
- Optional AI helper (new in version 0.98, July 2026). JASP says the AI feature is optional and must be switched on in Preferences, where you enter an API key. The release notes say the assistant works with "any OpenAI-compatible API", including OpenAI, Anthropic, Mistral, OpenRouter and local models. That means you need your own account with an AI provider, and that provider's price and data rules apply. JASP itself stays free. We did not test the AI helper.
Privacy and data
- JASP's FAQ answers "Does JASP violate my privacy?" with "No, JASP will never collect any user-identifiable information."
- The FAQ says JASP runs its R code inside a Windows sandbox with an allow-list of folders it may use.
- If you switch on the AI helper, the chat talks to the AI service you choose, so read that service's privacy terms. This is our note, not a JASP statement.
India
- We saw no country limit on the download page. We did not test it from India.
