Chart Caption Writer

Describe what your chart shows and get three pieces of text: a caption for the report, screen-reader alt text, and a one-line takeaway for the slide. Unpublished figures stay on your device, nothing is uploaded.

Describe your chart

What it plots, the axes, and the key numbers or trend you see

Caption, alt text, and takeaway

Your caption, alt text, and slide takeaway will appear here.

Alt text is the part worth getting right. Screen-reader users depend on it, so check that the alt text leads with what the chart shows and the actual values rather than saying "a chart of the data"; that is the most common accessibility failure in reports. The model only knows the numbers you typed, so verify every figure it repeats against the real chart before publishing, and be careful that the takeaway line does not claim a cause when your data only shows a correlation.
