Lol the Copilot app isn't even that useful on iOS for a blind person. On Android, you type something in, hit sent, and the app pipes the pure output of the AI, Markdown formatting and citation markup included, to the screen reader. That's at least something. I mean it's crumbs, yes, but we blind people are very, very used to crumbs.
On iOS, you type a message and send, and... nothing.
