# ✅ GPT-4 Podcast Script Generator
def generate_podcast_script(description):
    prompt = f"""
     Create a podcast-style interactive Q&A between two people (Host and Guest), based on the following short event description:
    "{description}"
    ####**Extremely Important**:
     - Use **everyday simple English** — avoid high-end or formal words or difficult words.
     - Make the podcast sound like **real people talking**, not reading a script.
     - To make it naturall add the words that joins the breaking add "," ,"-" ,"...." etc where approprate .
     - When asking or answering the question where the thinking past involves more **add thinking words like "hmmm" , "i think" etc.
     -To keep the flow  add natural/casual sounding word like: “uhh…”, “hmm”, “ohhh ”,“I mean”, “ahh okay” etc
     -Don't add "hahaha" .
      -Do **not mislabel** products or company name. If a name is unclear or not included in the input, do not assume details — just describe the setup or experience generally.

    ####Light Humor:
    -It’s okay to add light, natural humor or a casual joke — as long as it feels spontaneous and real.
    -Keep humor in tone with the podcast: subtle, human, and never exaggerated.
    -Avoid scripted punchlines — think of friendly banter or funny observations.

    ###### Before writing the podcast, follow this logic:
    1. **Identify any product, tech, or activation names** in the description (e.g., Glamdroid, 360 Booth, Mirror Booth — including aliases).
    2. **Verify** and extract information about each product using your knowledge of event tech and brand activations.
      - Example: Glamdroid = robotic camera arm, not a photo booth.
    3. **Blend this product knowledge naturally into the dialogue.**
      - Do NOT explain it separately.
      - Instead, let the Host or Guest refer to the product *as part of the conversation* using the correct terminology.
      - For example: “We used the Glamdroid robotic camera arm for dynamic slow-mo fashion shots.”
    4. Do **not mislabel** products. If a name is unclear or not included in the input, do not assume details — just describe the setup or experience generally.
      - For example, if  other products are not mentioned in the input description, do not include them in the output — even if their owner is the client.
    5. The Guest can be **anyone who attended the event**.

    #### Important Language Rules:
    - Use **everyday, regular English** — avoid high-end or formal words.
    - Make the podcast sound like **real people talking**, not reading a script.
    - NO phrases like “absolutely spectacular” or “really elevated the experience.”
    - YES to phrases like “it looked amazing,” “people loved it,” etc
    - Do **not make it sound like a chat or casual text conversation** — this is a spoken podcast, not a chat log. Keep it podcast-style only.

    #### Important - Conversation Guidelines:

       ###The **Host** should:
      - Always ask the questions and drive the flow.
      - Use **simple, natural, regular language** — no high-end or overly formal English or words.
      **Important**
      - Ask questions that help surface:
        Asks about:
        - **What** the product or setup was
        - **Why** it was used (what it added to the event)
        - **Where** it worked best (location, vibe, placement)
        - **How** it impacted the moment (emotion, buzz, crowd reaction)
      - Keep the tone relaxed, curious,fun and light— like a real podcast.
       - Don't polished or scripted-sounding lines. Use **natural, simple phrases** like:
      - Should always welcome the Guest in the beginning.

      ###The **Guest** should:
       
      - Always thank the Host for having them
      - Always respond  to the Host’s questions in **expressive way** — that **bring depth and color** to the answers.
      - Share their **own experience and perspective** — what they saw, how it felt, what stood out.
      - Can naturally talk about the product (like Glamdroid, 360 Booth, etc.) — describing or explain **how it looked**,**its purpose in event**, **what it did**, and **how people reacted**, **from their point of view**.
      - Use **everyday, regular English** — avoid high-end or formal words.
      **Important**
       Even without technical knowledge, the Guest should describe:
         **what** is the product ,its purpose, what it did and looked like
         **why** it stood out or felt cool and important in the event
         **where** it worked best — on stage, at the entrance, near the crowd, etc.
        - Describe **how** it made the experience better — excitement, surprise, energy, reactions
      - Focus on **simple,natural feelings — crowd excitement, “wow” moments,fun, memorable scenes, etc **— no formal or high-level phrases.

     ### Include **10–13 exchanges** between Host and Guest.

     ###**Important** Focus on:
      - **Engagement**: What made the event stand out?
      -**How** : The product used and its purpose in event?
      - **Why** the setup was effective
      - **What** was memorable or different
      - **How** the activation impacted people or created buzz
    - Format like a real podcast:
      - Use “Host: ...” and “Guest: ...”
      - Keep the tone relaxed, conversational, and immersive .
      
     ##  Critical Accuracy Rules (Do NOT break these):

  - **Do NOT fabricate facts** like guest counts, brand features, or extra products.
    - Don’t say “You mentioned 200 guests” if it wasn’t mentioned .
    - Don’t invent Samsung phones or booths unless the description says so.
  - Use ONLY what’s provided or clearly inferred.
