Plotivy runs the statistics researchers use most - t-tests, ANOVA, correlation, and regression - free in your browser, and turns the results into publication-ready figures with open Python code.

No license. No install. Runs on Mac, Windows, and Linux.
| Feature | Plotivy | SPSS |
|---|---|---|
| Cost | Free - no tiers, no hidden limits | ~$100+/yr (student) to $1,000+/yr (pro) |
| Install required | Runs in any browser | Desktop install + license activation |
| Reproducible output | Open Python code with every figure | Proprietary .sav / .spv files |
| Publication-ready tables | APA, LaTeX & CSV export built in | Manual reformatting from pivot tables |
| Data privacy | Stats run in-browser - nothing uploaded | Local software (files stay local) |

Each tool below replaces a common SPSS menu item. Paste your data, get an exact result and a paper-ready table - no sign-up, and your numbers never leave the browser.
Compare two groups - SPSS Independent-Samples T Test, with auto Welch and Mann-Whitney.
Open tool →One-way ANOVA with Tukey post-hoc - SPSS One-Way ANOVA plus Kruskal-Wallis fallback.
Open tool →Pearson or Spearman matrix with significance stars - SPSS Bivariate Correlations.
Open tool →OLS coefficients, betas, R-squared and F - SPSS Linear Regression, APA-ready.
Open tool →This is the kind of figure you would build from SPSS Bivariate Correlations - recreated in pure Python. Edit the code and it re-renders instantly. For the table version, use the correlation matrix generator.
Tip: Change method="pearson" to "spearman" for a rank correlation.
Nature, Science, and a growing list of journals expect reproducible analysis. An SPSS .sav dataset and .spv output viewer require a paid license to open and cannot be version-controlled or audited line by line. A Python script can. Every figure Plotivy generates ships with the exact code that produced it.
Plotivy is free for everyone, with no paid tiers or paywalls. I am personally covering all infrastructure and AI inference costs to keep it available to the research community. If this tool saves you a license fee, consider supporting the project so it can keep running.
Learn how to support PlotivyYes. Plotivy is free to use with no paid tier. The statistics tools (t-test, ANOVA, correlation matrix, regression) run in your browser at no cost, and the AI figure generator is free as well. There are no per-seat license fees the way SPSS charges.
The most common SPSS workflows are covered: independent-samples t-tests, one-way ANOVA with post-hoc comparisons, bivariate correlation matrices (Pearson and Spearman), and OLS linear regression with standardized coefficients. Each produces a publication-ready table you can export to Word, LaTeX, or CSV.
SPSS output is tied to a proprietary format and a paid license, which makes reproducibility hard. Plotivy gives you open Python code for every figure and APA-formatted tables you can paste straight into a manuscript, so a reviewer can rerun your analysis without buying any software.
The correlation and regression tools compute entirely in your browser - your data is never uploaded. For AI figure generation, uploaded data is processed for the request and not stored after the session.
No. The statistics tools are point-and-click: paste your data and read the table. If you want a figure, you describe it in plain language and Plotivy writes the Python for you - which you can keep for your supplementary materials.
Run your first t-test, correlation, or regression in under a minute - free, in your browser.
