Research Tools
Recover numeric data from a figure in a paper. Upload the image, calibrate the axes, click along the curve, and export the digitized values — your graph image and points stay in your browser. We'll ask for an email once before your first export, just to understand how the tool gets used.
Two clicks per axis maps pixels to real values.
Click along a curve; drag or edit any point after.
Overlay multiple curves and export CSV or Excel.
Select or create a dataset to view its points.
Click a button above, then click the matching reference point on the image. Enter the true axis value for each point on the right. Point selection advances automatically from X start to X end, Y start and Y end. The point just placed receives arrow-key control immediately; control transfers automatically when the next point is created. Click an existing marker to select it. Arrow keys nudge by 0.1 pixel for high precision (Shift + arrow moves 1 pixel).
No curve yet
Create a curve first, then switch to "Add Points" to start clicking on the graph.
Import a CSV or Excel file (X in the first column, Y in the second — a header row is fine) to overlay reference or simulation data. Not sure of the format? Grab the template above.
