PlotCh.at

In your browser, PlotCh.at lets you upload a picture of a chart and ask questions about what it shows.

PlotCh.at is an AI charting and data analysis chatbot that reads plots, graphs and other visual data from images and answers in plain language.

Behind it sit Google's Deplot and large language models.

Deplot first turns the image into a table of underlying values, and the language model then uses that table to explain the data in response to your questions.

That approach is handy when you only have a screenshot or a figure from a report and no access to the original spreadsheet.

You get a table to work from, plus a conversation about it.

As with any chart-to-table conversion, it is sensible to check extracted numbers against the image before relying on them.
