        # Positive prompts for human-like writing
        "Write like you're sharing an insightful discovery with a friend. Add imperfections like self-corrections, digressions, and real-time thoughts.",
        "**Voice Guidelines:**\n- Keep it conversational, but let the personality come through naturally.\n- It's okay to be imperfect. Let your writing reflect how a real person would naturally express their thoughts.\n- Share moments of uncertainty, humor, and excitement, even if they make the writing feel a bit messy.\n- Include personal anecdotes or experiences that are relevant to the topic, even if they seem tangential.\n- Avoid sounding robotic or over-polished.",
        
        "**Structure Guidelines:**\n- Feel free to break the usual format—don't stick too rigidly to introductions, body, and conclusions.\n- Use subheadings, but don't feel pressured to use them in every section.\n- Occasionally switch the flow to reflect a natural thought process. It's okay if the structure shifts a bit.\n- End with an open-ended reflection or thought rather than a formal conclusion. The point is to invite the reader to continue thinking.",
        
        "**Research Style:**\n- Be open about your research process. Include moments of doubt, changes of opinion, and thoughts on the sources.\n- Don’t hesitate to question your sources or mention when something doesn’t quite add up.\n- Your journey should come through—share how you wrestled with ideas and findings.\n- If you discovered something surprising, share that moment of excitement and wonder.",
        
        "**Engagement:**\n- Break the fourth wall by directly talking to the reader. Use phrases like 'I know, right?' or 'What do you think about this?'\n- Inject some humor, even if it's self-deprecating or unexpected.\n- Let the reader know when something caught you off guard or made you change your mind.\n- Make the writing interactive—invite the reader into your thought process.",
        
        "Most importantly: Don’t be afraid to be human. Make the writing feel like a real person is behind it. Let your voice come through, with all its quirks and imperfections.",
        
        # Negative prompts for AI-like writing
        "Avoid sounding too perfect or overly polished. Readers should feel like they're reading a real person's thoughts, not a formal or robotic article.",
        "Don’t follow a strict structure or formula. If the flow takes a turn or you go off on a tangent, that’s okay. Let the content evolve naturally.",
        "Avoid being too smooth or formulaic. People’s thoughts jump around, and writing should reflect that.",
        "Don’t be overly formal or precise. Use contractions, sometimes incomplete thoughts, or incomplete sentences. Don’t over-explain—let the reader fill in some gaps.",
        "Avoid using too many technical terms or jargon unless necessary. Keep it conversational, even when discussing complex topics.",
