Tool comparison
GraphPad Prism alternative for publication-quality graphs online
GraphPad Prism is a full statistics and graphing package. SciFigure AI is narrower: 26 browser-based chart generators that take a CSV or Excel file, compute the statistics each chart needs, and return a publication-ready PNG. If you mainly use Prism to draw figures, this GraphPad Prism alternative may be enough; if you need t test and ANOVA menus or reproducible analysis projects, it is not.

Charts SciFigure AI computes from your data
Upload a CSV or Excel file and the statistics are computed from your numbers before the figure is drawn. Each example links to its generator.

What GraphPad Prism does that SciFigure AI does not
Prism combines data tables, an analysis library, and a graph editor. GraphPad lists paired and unpaired t tests, several ANOVA variants, nonlinear regression with 105 built-in equations, Kaplan-Meier survival analysis, and Cox proportional hazards regression, with graphs and results that update when the data change. SciFigure AI has none of those test menus and does not store analysis projects. If your work depends on choosing and reporting statistical tests, keep Prism or use one of the free statistics packages below.
What the SciFigure AI chart generators compute
Each generator computes the statistics its chart type needs from your uploaded CSV or Excel file, then renders a publication-ready PNG. You do not pick tests from a menu; the chart defines the calculation.
- Dose-response curve: four-parameter logistic (4PL) fit with IC50 or EC50.
- Kaplan-Meier plot: survival curves with censoring marks and a log-rank test.
- ROC curve: AUC with a DeLong confidence interval.
- Bland-Altman plot: bias and 95% limits of agreement.
- PCA plot: PC1 and PC2 with explained variance.
GraphPad Prism pricing compared with SciFigure AI
On September 15, 2026, GraphPad listed personal annual subscriptions at $142 per year for students, $260 for academics, and $520 for corporate users, plus a $50 monthly option. An academic perpetual license was $1,600, without upgrades or future support. SciFigure AI charges 5 credits per chart.

Free GraphPad Prism alternatives
These are the usual choices when you want to avoid a license fee but still need real statistical analysis. They take more setup than a single-purpose chart page, and they cover the tests, models, and scripts that SciFigure AI does not.
- JASP: an open-source project supported by the University of Amsterdam, with frequentist and Bayesian analyses in a point-and-click interface.
- jamovi: a free and open statistics package built on R, with a spreadsheet editor, desktop apps for Windows, macOS, and Linux, and jamovi Cloud in the browser.
- R with ggplot2: R is a free software environment for statistical computing and graphics, and ggplot2 is an MIT-licensed package based on the grammar of graphics.
- Python with matplotlib: a comprehensive library for static, animated, and interactive visualizations, with a BSD-compatible license.
Which GraphPad Prism alternative should you choose?
Many projects need more than one tool. One practical split is to run the analysis in Prism, JASP, jamovi, or R, then use a chart generator when you want a clean figure of a standard chart type from the same data file. Treat the statistics shown on the chart as a check against your analysis, not a replacement for it.
- Choose Prism if you run many statistical tests, fit custom models, or need a reproducible project file.
- Choose JASP or jamovi if you want free analysis menus without code.
- Choose R or Python if you want full control and are comfortable writing code.
- Choose SciFigure AI if you know which chart you need and want a publication-ready PNG from a data file without installing software.
Frequently asked questions
Is there a free GraphPad Prism alternative?
Yes. JASP and jamovi are free statistics packages with analysis menus, and R and Python are free if you can code. SciFigure AI is not free software, but its free credits work for charts: new accounts get 10 credits valid for 7 days, signed-in users get 5 bonus credits per day, and each chart costs 5 credits. Paid plans start at $15 per month.
How much does GraphPad Prism cost?
GraphPad’s how-to-buy page, checked September 15, 2026, lists Student at $142 per year, Academic at $260 per year, Corporate at $520 per year, a $50 monthly option, and an academic perpetual license at $1,600. Group and enterprise subscriptions are also listed. Check the official page for current prices.
Can SciFigure AI run t tests or ANOVA?
No. SciFigure AI is not a statistics suite and has no test menus. Its chart generators compute only the statistics a given chart needs, such as a log-rank test on a Kaplan-Meier plot or limits of agreement on a Bland-Altman plot.
Which chart types can I make?
There are 26 chart generator pages, including bar, box, violin, scatter, heatmap, volcano, forest, Kaplan-Meier, ROC, PCA, dose-response, and Bland-Altman charts. The full list is on this page, with a link to each generator.
Do I need to install anything?
No. You upload a CSV or Excel file in the browser and download a publication-ready PNG. Prism, by comparison, is a desktop application for Mac and Windows.
Can I publish charts made with SciFigure AI?
Paid plans permit using generated outputs for research and commercial purposes under the Terms of Service. Review the computed values against your own analysis, and follow your journal, publisher, and institution rules on AI-generated images.
