Learn how to write effective system prompts and initial messages for your AI assistants

Larsaai.com uses a System Prompt to guide how your AI assistant interacts with callers. Crafting an effective prompt is key to smoother, more accurate phone conversations.


​1. System Prompt vs. Initial Message

  • System Prompt: Overall instructions and context. Example:
    “You are the Support Bot for TechMasters Inc. Greet politely, ask for a name, handle basic troubleshooting, and transfer the call if the issue is complex.”

  • Initial Message: The first thing the AI says, especially for inbound. Example:
    “Thank you for calling TechMasters! How can I assist you today?“


​2. Clarity & Structure

  • Be Specific: Outline the main purpose, tone, and steps you want the AI to follow.

  • Use Examples: Show sample dialogues. “If the user says they have a billing question, ask them for their invoice number.”

3. Handling “Unknown” Cases

  • If a user asks about something off-topic, decide whether the AI should:

    • Provide a default response: “I’m not sure, let me transfer you…”

    • Gather more details.


4. Keep It Short & Focused

  • A short prompt often works best; too-long instructions can make the AI slower or prone to “hallucination.”

  • If you have lengthy content, consider a knowledge-base or chunk your text with headings.



Tip: Periodically review your transcripts to see where the AI might need more or fewer instructions.
