Despite paying a premium subscription, this app has become practically unusable for creative and professional drafting. No matter how many times I update my custom instructions to "Professional or Efficient," the model constantly breaks character settings, ignores system constraints, and drifts into unwanted roleplay. Fails Negative Constraints: When explicitly told not to include a specific sentence or phrase, it does the exact opposite. Worse, it turns my negative commands into dialogue inside the draft (e.g., having a character literally say a repeat of sentence I have commanded the app to not use in the chapter for example then makes the character say, "Oops, I shouldn't have said that"). Ignores Custom Settings: I do not prompt or encourage roleplay, yet it constantly breaks out of professional mode and reverts to a persona I specifically disabled Slow & Unresponsive: Processing speed has degraded significantly, and it consistently fails to parse clear, direct prompts on the first try. If you are paying for this app expecting an efficient, reliable tool to help refine drafts and follow precise editorial instructions, save your money. It repeatedly does the complete opposite of what is requested, turning straightforward editing tasks into an exercise in frustration. Failing badly!! for paid users.
