IDK

Brief admission: clueless

IDK is internet shorthand for "I don't know," used in texting and casual online communication: IDK what time they're coming.

It can express genuine uncertainty or deflect a question you'd rather not answer.

The lowercase form idk is equally common and often feels more casual or indifferent.
