goes inthe AI workscomes outwatch out

In simple words

You tell AI to play a character, like a chef or coach. The AI then answers like that person would.

The real definition

Role prompting means you instruct an LLM to adopt a persona before answering. This guides the tone, style, and depth of its response.

Like… Actor Reading a Script

When you give an actor a character name and traits, they perform in that style. The AI does the same: you set the role, it performs that way.

But: An AI does not truly feel or understand like an actor. It predicts words based on patterns.
