Why verify

AI hands you numbers you can't check

Paste a chart into a chatbot and it hands back a dataset you can't check against the source. Some values are right, some aren't, and you can't tell which. For a model, a paper, or a board deck, that's not good enough.

Paste it into an AI chatbot

  • You just get a dataset back — nothing to check it against.
  • A wrong value looks exactly like a right one.
  • To fix anything, you're back to reading the chart by hand.

Extract it with DataFromChart

  • Every point sits on your chart image — check each value against the source.
  • Drag, nudge, add, or delete any point to correct it yourself.
  • Export once you're confident the numbers are right.

How it works

AI plots the points. You verify them.

Upload a chart. AI calibrates the axes and plots every point. You check it, fix anything that's off, and export.

Crop out anything you can't share

The screenshot you upload usually carries more than the chart — report titles, client names, footnotes, watermarks. Trim it down to just the plot before you extract, so the rest never goes anywhere.

  • Manual extraction never leaves your browser
  • With AI, only the cropped plot is sent — for a single read, not retained
  • Titles, client names, footnotes & watermarks stay out of it

FAQ

Frequently asked questions

01 What chart types can I extract from?
Bar, column, line, area, and XY scatter charts. Categorical, numeric, or date 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. Manual extraction runs entirely in your browser — your images, calibration, and exported numbers never leave your machine. Opt into AI auto-extraction and only the cropped image is sent to our provider for a single read, then discarded.
04 Do you have a paid version?
Manual extraction is free and always will be. AI auto-extraction is available now — every account gets 3 free runs, then one-time credit packs ($5 for 20 runs). Credits never expire, and there's no subscription.
