Skip R, Python, and Excel. Describe your distribution parameters in plain language and get a professional bell curve graph back — ready for your paper, presentation, or exam.
Enter the mean, standard deviation, and what you want to highlight — confidence intervals, shaded regions, comparison curves, or grade distributions. Use natural language, not code.
The AI plots an accurate normal distribution curve with proper axis scaling, labels, and shading. You get a statistically correct graph within seconds.
Export as high-resolution PNG for slides and posters, or editable SVG for fine-tuning in Illustrator, Figma, or Inkscape. Paste directly into your report, thesis, or presentation.
Students · Researchers · Analysts
Whether you're studying for a stats exam, publishing a research paper, or running quality control in a factory — the same tool adapts to your needs.
From STAT 101 to advanced methods
You need a bell curve for your homework or exam prep — but you don't want to learn R or Python just to make one graph. Describe what you need and get a textbook-quality normal distribution in seconds.
Publish faster, visualize clearly
Your paper needs a clean normal distribution figure that meets journal standards. Instead of wrestling with ggplot or matplotlib, describe your parameters and get a publication-ready figure — editable SVG included.
Prep less, teach more
Stop building bell curve graphs by hand in Desmos or GeoGebra for every lesson. Describe the distribution once and get a clean, projector-ready graph with the shading and labels your students need.
Bell curve examples across disciplines
Every graph below was generated from a plain-text description. Click any example to load the same prompt and try it yourself.
z-scores with shaded confidence regions
Percentile ranges and population labels
Grade boundaries and letter grade regions
Control vs. treatment overlaid curves
95% CI around the mean with error interpretation
Specification limits and defect regions
Most bell curve tools make you enter parameters into rigid forms. This one reads your natural-language description — just like you'd explain it to a colleague.
Plain-Language Parameter Entry
Write 'IQ distribution with mean 100 and sd 15, shade top 2.5%' — the AI parses the parameters, calculates the thresholds, and plots an accurate curve. No programming, no spreadsheet formulas.
Proper Axis Scaling and Distribution Shape
Every bell curve uses the exact Gaussian probability density function. X-axis scales match your specified mean and standard deviation. Shaded regions correspond to the correct cumulative probability.
Confidence Intervals, Tails, and P-Values
Shade left-tail, right-tail, or two-tailed regions. Overlay the 68-95-99.7 empirical rule zones. Mark critical values, z-scores, or grade boundaries. The AI handles all the probability calculations.
Control vs. Treatment, Pre vs. Post
Plot two or more bell curves on the same axes to compare distributions. Show treatment effects, group differences, or pre-post changes with clear visual separation and labeled means.
Ready for Any Document
Download as high-resolution PNG (2K or 4K) for presentations, or editable SVG for Illustrator, Figma, and Inkscape. Every export is 300 DPI for print-ready quality in journals and posters.
Psychology, Education, Manufacturing, Finance
Generate IQ score distributions for psychology, exam grade curves for education, Six Sigma control charts for manufacturing, or return distributions for finance — no field-specific configuration needed.

Priya Nair
Statistics PhD Student, University of MichiganI needed five normal distribution figures for my dissertation chapter on hypothesis testing. Instead of writing ggplot scripts for two hours, I described each one here and had all five in under three minutes.
Dr. Marcus Webb
Assistant Professor of Psychology, UC DavisMy research methods students used to spend an entire lab session learning to plot bell curves in R. Now I point them here — they focus on interpreting the graphs instead of debugging code.
James Okonkwo
Quality Engineer, Automotive ManufacturingI use this for our weekly Six Sigma report. The specification limit shading and process capability labels are exactly what our plant manager expects. Way faster than Minitab for one-off graphs.
