AI tools with real business use cases?

Aside from the usual suspects (ChatGPT, Bard, ...) which AI tools have a valuable use case in a business or job?

Most AI tools I see being paraded in viral tweets and YouTube videos seem gimmicky (e.g. an app for turning you into a robot when you use the front camera).

They're interesting, they're cool, they're new, but ultimately I don't see valuable use case for them.
