Shape your chatbot with custom prompts

Defining a custom prompt in the Biel.ai LLM settings

Two teams with the same docs often want the chatbot to behave differently, so you can now write a custom prompt that shapes how yours answers.

A few ways this plays out:

  • Set priorities: tell it to point users to the migration guide first when they ask about upgrading
  • Flag limitations: tell it to say a feature is beta, or that self-hosting isn't supported, instead of guessing
  • Control tone and patterns: keep answers short and code-first, or always end with a link to the relevant page

You write it in Settings > Chatbot > Custom prompt, and it applies to every answer from the next question on. The custom prompt docs have examples you can adapt.

One tip: write rules around what users ask, not what you want the bot to be. "When someone asks about pricing, link to the plans page" fires reliably; "be helpful" does nothing.
