Statistical Graph Maker
Make Statistical Graphs From Your Data — With the Stats Built In
FigureGuild's Graph Builder turns your raw data into publication-ready statistical charts. Paste your data, pick a chart type, and the right statistical test runs automatically — no coding, no separate stats software.
Statistics computed from your real data — never invented
t-test, one-way and two-way ANOVA with post-hoc corrections, Mann-Whitney U, Kruskal-Wallis — all computed locally in your browser by our own deterministic code. The AI never generates, alters, or guesses a statistical value.
Significance brackets and asterisks are placed automatically based on the actual p-values from your data. Not estimates. Not approximations. Real statistics from your real numbers.
You never need to verify whether the AI hallucinated a p-value, because the AI never touched your data.
Statistical charts, not just drawings
Each chart type is designed for scientific publication with the appropriate statistical test built in. Not decorative — data-driven.
Bar & Column Charts
Individual data points, mean ± SD/SEM, and automatic significance brackets with t-test or ANOVA.
Box & Violin Plots
Full distribution with quartiles, IQR, and outlier points. Mann-Whitney or Kruskal-Wallis computed automatically.
Scatter Plots
Regression lines, R², Pearson or Spearman correlation — all computed from your actual data points.
Kaplan-Meier Survival
Log-rank p-value, confidence intervals, and at-risk table computed from your survival data.
Volcano Plots
Differential expression with FDR threshold and fold-change cutoff. No AI-generated gene labels.
Heatmaps
Hierarchical clustering and Z-score normalization computed from your expression matrix.
PCA Plots
Variance-explained percentages and 95% confidence ellipses computed from your multivariate data.
Forest Plots
Weighted squares, confidence intervals, and pooled estimate diamond — all derived from your effect sizes.
Editable, never rasterized
Charts export as editable vectors — every label, axis value, and significance bracket stays as editable text and shapes. No rasterization. No locked layers. No AI-generated text that you can't fix.
Other tools advertise "editable SVG export" because their AI generates text and then tries to correct errors. FigureGuild doesn't generate your data — it plots it. Every label, value, and statistic comes straight from your raw data unchanged.
Export at journal DPI: PNG, PDF, SVG, or TIFF at 300, 600, or 1200 DPI. Sized to your journal's column width (Nature, Cell, Science, and custom dimensions).
A web-based Prism alternative
No installation. No license renewal. No IT approval. Paste your data from Excel, choose your chart, and get a publication-grade statistical figure in seconds.
FigureGuild covers the core statistical charting workflow of GraphPad Prism — with the added benefit of multi-panel assembly, AI graphical abstracts, and a web-based workspace that works on any device.
Free to try. Export for Nature, Cell, Science, eLife, PLOS, and PNAS with one-click journal presets.
Frequently asked questions
What statistical tests does FigureGuild run?
FigureGuild computes t-tests, one-way and two-way ANOVA with post-hoc corrections, Mann-Whitney U, Kruskal-Wallis, and log-rank tests for survival curves. All statistics are computed locally in your browser from your raw data — never generated or guessed by AI.
Can I use FigureGuild instead of GraphPad Prism?
Yes. FigureGuild covers the core statistical charting workflow of Prism: paste data, choose a chart type, run the appropriate statistical test, and export at journal DPI. It's web-based with no installation or license required, and includes multi-panel assembly and AI graphical abstracts that Prism doesn't offer.
What chart types are supported?
Bar and column charts, box plots, violin plots, scatter plots with regression, Kaplan-Meier survival curves, volcano plots, heatmaps, PCA plots, and forest plots. Each chart computes the appropriate statistical test automatically.
Are the statistics accurate? Can I trust them?
Yes. Statistics are computed locally by our own deterministic code from your raw data. The AI never generates, alters, or guesses a statistical value. Significance brackets and p-values are derived directly from your data points, not estimated or hallucinated.
