Workflow

Four steps from chart to data

One chart, four screens. Drop it, calibrate the axes, plot each point, walk away with clean data.

01

Upload

Drop in a PNG, JPEG, or SVG. Drag from a screenshot tool, paste from clipboard, or pick a sample chart. The source format doesn't matter.

Calibrate

Drag the axis reference lines onto the gridlines and enter the min/max. AI auto-detect Coming soon will handle calibration in one pass.

FAQ

Frequently asked questions

01 What chart types can I extract from?
Bar, column, line, area, XY scatter, and combo charts. Categorical or numeric x-axes. Linear or logarithmic y-axes. Single- or multi-series — labeled and exported together.
02 How accurate is the extracted data?
A careful operator on a clean chart image typically achieves under 1% mean absolute error of the y-axis range — an order of magnitude better than current vision LLMs.
03 Do you store the charts I upload?
No. Extraction runs entirely in your browser. Your chart images, calibration, and exported numbers never leave your machine.
04 Do you have a paid version?
Not yet — DataFromChart is free. A paid tier with AI auto-detect, batch processing, and team features is on the roadmap; the core extraction workflow will stay free.
