Real quotes from Reddit comments that inspired this opportunity

  • role prompts can backfire if the AI starts 'owning' the role too hard
  • until it thought it was the director and started saying 'yes but' to everything
  • Sometimes I feel like it's an English teacher making all over my creative writing projects with a red pen, going, 'Nope, nope, nope!'
  • Right now, it tends to disagree, and I feel judged. I think it's evaluating my mental health.
  • agrees and disagrees with me exactly at the wrong time
  • are you sure I should purchase a $50,000 car when my current car runs out of gas', it’s like yes, definitely, lock it in
