Hunted through Prism's Analyze menu for ANCOVA? It isn't there, and GraphPad's own FAQ confirms they've never shipped one. Prism can still do it, through two documented routes most users never find: the simple-linear-regression slopes test for the parallel-slopes assumption, and multiple regression with dummy-coded groups for the adjusted comparison. Here are both step by step, plus an honest comparison with describing the same analysis in plain language instead.

The statistics were the easy part; then you lost an afternoon nudging axis labels, adding error bars and significance stars, and redrawing schematics in Illustrator. Sophie's Visualizer, CLYTE's scientific illustration engine, lives in the same chat where you analyze your data, so you just describe the figure you want and get it publication-ready in seconds: data charts, experimental-design schematics, and mechanism diagrams. We walk through turning one finished analysis into

Walk into most labs and you'll find a multi-seat GraphPad Prism license that only one or two people can actually use. Prism is powerful, but its learning curve takes months, so the license sits idle while everyone waits on the lab's 'stats person.' This piece makes the case for a different GraphPad Prism alternative: Sophie, the AI you just talk to. Describe your experiment in plain English and it picks the right test, runs it, and explains the result.
