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 20 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.
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.
If it's a chart, we read it.
Linear, logarithmic, date/time, reciprocal. Pick the scale and Plotion calibrates accordingly. Mixed scales? Multi-axis? Ternary? Yes, yes, yes.
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.
- → axis-tick alignment
- → curve variance σ
- → effective DPI of source
- → AI-vs-manual disagreement δ
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.
