The Artifact news reader app on iOS uses this premise to provide one of the truly useful implementations of LLMs I've seen in the wild so far. You can mark a title as clickbait, and the app will use AI to generate a new title, usually one that is more usefully descriptive.

It's not perfect, sometimes the generated title is still totally clickbait and I've seen a couple instances of it being completely wrong or hallucinating a detail. But generally it's pretty neat.

The app also uses the same tech to summarize articles into a few bullets which I don't use as often but is also neat.
