Re: software for alt text?

I'd second what Sarah said.

Part of having a text alternative is knowing whether the text serves
the *equivalent
purpose* to the non-text content (image, etc.). A machine-based solution
isn't yet at a point where it knows what the purpose behind the non-text
content is all the time, so having a human check over things is still the
best option.

Taking images as an example, all I use a tool for is to catch images that
are missing their *alt attribute*. When I see those I know to check the
content around the images to see if there's an alternative there (and also
know to highlight that an alt attribute needs adding, whether we add text
to the attribute or not). I'll then manually check every image that *does* have
an alt attribute to make sure it makes sense for the purpose of the image.
I wouldn't trust a machine or software to do that kind of nuanced check,
yet.
