Custom prompt

A prompt is the instruction or set of instructions given to the chatbot that guides how it processes and responds to user input.

Biel.ai provides three options for configuring your chatbot's behavior:

This is the recommended prompt that comes pre-configured with built-in restrictions and optimizations specifically designed for technical documentation and support interactions. It includes:

  • More restrictive to context: Only responds based on available context and documentation
  • Reduced hallucinations: Won't answer unless there's a high degree of certainty
  • Enhanced accuracy: Built-in safeguards for precise responses
  • Optimized processing: Advanced features for documentation handling

Trade-off: The assistant won't provide responses when it doesn't have sufficient information, even if it could potentially extrapolate from similar content.

Example: If you don't have installation docs for a specific framework but have docs for other frameworks, AI Assistant v2 won't provide a response rather than attempt to extrapolate.

Option 2: AI Assistant v1​

This option provides more freedom in responses while maintaining core safeguards. It includes:

  • More flexible responses: Extrapolates from available information and uses existing knowledge
  • Broader coverage: Attempts to provide helpful responses even with limited context
  • Creative problem-solving: Can make educated guesses based on similar scenarios

Trade-off: Higher potential for hallucinations and less accurate responses when information is incomplete.

Example: If you don't have installation docs for a specific framework but have docs for other frameworks, AI Assistant v1 will try to extrapolate and provide installation guidance based on similar patterns.

When to use each version
  • Use AI Assistant v2 when accuracy is critical and you prefer no response over potentially incorrect information
  • Use AI Assistant v1 when broader coverage is preferred and occasional inaccuracies are acceptable

You can extend either AI Assistant version by adding specific instructions. For example:

  • Adding a signature to every response
  • Including specific phrases in responses
  • Modifying the tone or style while maintaining core functionality

Option 3: Custom prompt​

For complete control over the chatbot's behavior, you can define your own custom prompt. This option allows you to:

  • Define the exact personality and behavior
  • Set specific response patterns
  • Customize the interaction style
  • Target specific use cases

Defining your own custom prompt gives you full control over the chatbot's behavior, but it may disable some of the platform's built-in safeguards and advanced processing features.
