What's the best general purpose AI companion prompt that combines the advantages of roleplay but also feels more like genuine connection? Something you can just turn on when you want to talk to someone and feel comforted or understood. But something with more agency, like a character.

Best ways to really change the character and avoid GPTisms and excessive lecturing?
