AI extraction · margin of error included

From pixels
to numbers.

Drop any chart image. Plotion places the axes, traces every series, and ships the dataset with a computed margin of error. Built for researchers who cite their sources.

Drop. Describe. Done.

The whole loop, from a screenshot in someone else's paper to a CSV in your hand. Adjust anything mid-flight with a drag.

Drop a chart image

PNG, JPG, SVG, GIF, WebP, BMP. Up to 10 MB. Crop right in the browser before any pixels leave your machine.

Describe what you see

A short sentence is enough. "x is years, y is in thousands, log scale on y." Plotion uses it to seed the axis calibration and the AI starting points.

"y is thousands of people"
/03

Verify, export, cite

Every point is draggable. Margin-of-error follows you in real-time. CSV, XLSX, JSON, Python, MATLAB. The σ column comes along.

7 chart families · 4 axis scales

If it's a chart, we read it.

Linear, logarithmic, date/time, category. Pick the scale per axis and Plotion calibrates accordingly. Multiple series on one chart? Mixed scales on X and Y? Yes and yes. XY, Bar, Pie, Polar, Ternary, Geo and Scale-bar are all live today.

An honest number,
not vibes.

Plotion computes ±% from axis-tick alignment, curve variance, and your image's effective resolution. Reviewers stop asking "how accurate is this?" because the answer is right there.

Drag the slider.

Higher resolution images give Plotion more pixels to lock onto. Watch the margin shrink as the source quality goes up. The number you ship in your paper is the same number you see here.

  • curve variance σ
  • effective DPI of source
  • AI-vs-manual disagreement δ
export · 6 formats · σ included

Ship it your way.

One click to CSV, XLSX, JSON, Python list, MATLAB matrix, or a clipboard-ready paste for Google Sheets. Every format ships with the σ (margin) column attached.
