Yes, ChatGPT can be customized, in two ways: giving it custom instructions or using data to train the AI.

These are two very different things, even though they sound similar.


There you go. ChatGPT’s custom instructions are one most helpful features.

  • Use these so you can tell ChatGPT the way you want it to answer your questions.
  • Avoid saying the same thing over and over again.
  • This is why people use custom instructions.
