I'm building a web browser [1] that tries to make the semantics of the web automateable, so its goals are kind of aligned with blind people in regards to semantics and extraction.
My knowledge of how blind people use the web is kind of outdated, though. Is JAWS still a thing?
(My web browser is far from being stable, lots of things don't work yet and there's a ton of work left)
Edit: To answer your other question, yes, JAWS is still maintained and widely used, but it's not as dominant as it once was. On Windows, the NVDA open-source screen reader is quite popular, and the built-in Narrator screen reader is on the rise (though of course I'm biased, since I worked on it). iOS with its built-in VoiceOver screen reader is also quite popular among blind people, at least in the US.
