I don’t use WhatsApp, but this immediately made me think of my dad who doesn’t use any punctuation and frequently skips and misspells words. His messages are often very difficult to interpret, through no fault of his own (dyslexia).

Having an LLM do this for me would help both him and me.

He won’t feel self conscious when I send a, “What you talkin’ about Willis?” message, and I won’t have to waste a ridiculous amount of time trying to figure out what he was trying to say.
