jamovi vs Celeus: how the two tools compare
jamovi is a free, open source desktop program you drive from menus. Celeus runs in your browser and suggests a method for your data. Dated, sourced comparison.
Written by Celeus, which makes one of the two tools compared. Facts about jamovi come from jamovi's own pages and were last checked on .
jamovi is a free, open source statistics program. You choose an analysis from its menus, set the options in a dialog, and read the results; nothing needs to be programmed. It runs as a desktop app or in the browser through jamovi Cloud, and each analysis can show the R code that produced it.
Celeus starts from your data instead of a menu. After you upload a file, it suggests methods that fit the dataset’s structure, and you can ask the AI for a suggested test. The calculations run in R, not in the AI model, and each run downloads as one package: the plan, the exact R script, the seed, session info, the results and an audit log. Celeus has no desktop app and does not work offline.
The two overlap less than it may seem. jamovi suits people who already know which test they want and value a free, local tool. Celeus suits people who want help choosing the method and a record of exactly how each result was produced.

|---|---|---|
| Price and free tier | The desktop app is free. jamovi Cloud has a free Guest plan, a Priority plan priced by region, and custom quotes for teams and institutions. (jamovi, as of ) | Free plan; Pro is $19 a month for one researcher. |
| Where it runs | A desktop app for Windows, macOS and Linux (Chromebooks through Flathub), and jamovi Cloud, which runs it in a web browser. (jamovi, as of ) | In a web browser. No desktop app and no offline mode. |
| How the method is chosen | Point and click: you pick an analysis from a menu and set its options in a dialog, with no programming. (jamovi, as of ) | Celeus suggests methods that fit your dataset's structure, and the AI suggests a test when you ask for one. The statistics run in R, not in the AI model. |
| AI involved, and what of your data reaches it | Not compared | The AI model receives: column names, types and variable labels stored in your file; summary statistics, including each numeric column's minimum and maximum; category names, with small counts withheld; aggregate results of your analyses; text you write: chat messages, research questions, notes and codebook descriptions; dataset names (by default, the name of the file you uploaded). It never receives: your uploaded file; data rows or data tables. |
| Reproducibility output | Each analysis can show the R code behind it, and one file keeps the data, the analyses, their options and the results together. (jamovi, as of ) | The plan, the exact R script, the seed, session info, the results and the audit log, in one download. |
| File formats it opens | Opens SPSS, SAS, Stata, CSV and Excel files, among others. (jamovi, as of ) | CSV, TSV or Excel on every plan; SPSS, Stata and SAS on paid plans. |
| Breadth of methods | Common analyses such as t-tests, ANOVA, regression, frequencies and factor analysis are built in, and more can be added from a community library. (jamovi, as of ) | 40 statistical methods. |
| Licence | Free and open source, for any use including commercial work. (jamovi, as of ) | Proprietary hosted service. |
Who each tool suits
jamovi: Students, teachers and researchers who want a free point-and-click program on their own computer, including offline work, and who like to see the R code behind each analysis.
Celeus: Researchers who would rather not pick the test from a menu: you upload a dataset in the browser, get methods suggested for its structure, and download a reproducible package for each run.
Where jamovi is the stronger choice
- It works fully offline on the desktop, and your data files and analyses never leave your computer. (jamovi, as of )
- It costs nothing for any purpose, and its source code is open for anyone to inspect or build on. (jamovi, as of )
- You can run R inside the app with your data already loaded, and its analyses are also published on CRAN as the jmv R package. (jamovi, as of )
- Every student can install it at home for free, which makes it easy to adopt for a first statistics course. (jamovi, as of )
