Frequently Asked Questions
What is a system prompt?
A system prompt is the initial instruction given to an AI that defines its role, personality, capabilities, and constraints. It shapes how the AI responds to every user message and is essential for creating consistent, on-brand chatbot experiences.
Can I customize the generated prompt?
Absolutely! The generated prompt is a starting point. Copy it and modify any part to better fit your specific needs, add company-specific information, or adjust the tone and behavior.
What AI platforms does this work with?
The generated prompts work with any AI platform that accepts system prompts, including OpenAI (ChatGPT/GPT-4), Anthropic (Claude), and other LLM providers. The format is universal and platform-agnostic.
Should my bot admit it's an AI?
It depends on your use case and audience expectations. Being transparent about AI nature builds trust, but some scenarios benefit from a more natural, conversational style. Our identity options let you choose what works best for you.
How do I test my chatbot prompt?
Start by testing in a development environment with various user queries. Check that the bot maintains its personality, handles edge cases appropriately, and provides helpful responses. Iterate based on real user feedback once deployed.
