Deep Dive
Workflow Differences
Prism guides you through a structured workflow: choose a graph type, enter data into a formatted table, and select analysis options from menus. This is excellent for standard experiments (e.g., dose-response curves) as it reduces the chance of selecting the wrong test.
Plotivy is more free-form. You upload your data and describe what you want. "Perform a one-way ANOVA and plot the results as a bar chart with error bars." The AI interprets this and writes the code. This is faster for custom analysis but requires you to know what you're asking for.
Reproducibility
This is a key differentiator. Prism saves your work in a proprietary `.prism` file. Plotivy generates open-source Python code.
If you need to share your analysis with a colleague who doesn't have a Prism license, they can't open your file. With Plotivy, you can send them the Python script, and they can run it anywhere (even if they don't use Plotivy).
Prism Capabilities for Free
Plotivy handles the core visualizations that biological researchers rely on Prism for. And it does it for free.

GraphPad Prism vs R: The Coding Question
Many researchers compare GraphPad Prism vs R when deciding between a GUI tool and code-based analysis. Here's how they compare:
| Aspect | GraphPad Prism | R / Python | Plotivy |
|---|---|---|---|
| Learning Curve | Low (GUI) | High (Programming) | Low (Natural Language) |
| Reproducibility | Medium (.prism files) | High (Scripts) | High (Python export) |
| Flexibility | Limited to built-in | Unlimited | High + Editable Code |
| Cost | $199-599/year | Free | Free |
The best of both worlds: Plotivy gives you the ease of a GUI (describe what you want in plain English) while generating R/Python-quality reproducible code. No programming knowledge required, but you get full code access.
