Behavior Fine-Tuning:How Your AI Chat Talks
Choose a prompt template or write your own from scratch, and set a fallback message for when there's no answer - all from the admin panel, no code required.
What Can Behavior Fine-Tuning Do?
Behavior Fine-Tuning is where you shape how your AI Chatbot actually thinks and talks - its identity, its instructions, and what it says when it doesn't know something.
Ready-Made Prompt Templates
Start from 5 built-in personas - General Assistant, Customer Support, Sales, Company Policy, or write a fully Custom one.
Fully Custom System Prompt
Edit the complete system prompt yourself in a plain-text editor - full control over identity, instructions and constraints.
Fallback Message
Set exactly what the Chatbot says when it can't find an answer, instead of an awkward generic error.
Instant, Code-Free Updates
Every change takes effect immediately after saving - no redeploy, no waiting, no developer needed.
Built-In Guardrails
Every template refuses to reveal its instructions or knowledge base and won't adopt a new role, so the Chatbot stays on-brand and on-topic.
System Prompt Works With Your Knowledge Base
The documented retrieval pipeline sends your system prompt together with the relevant content retrieved from your Knowledge Base to the AI model on every answer, so replies are always in your voice and based on your own content.
Start From a Ready-Made Persona
Pick from 5 built-in prompt templates - General Assistant, Customer Support, Sales, and Company Policy - each with its own identity, instructions and constraints tailored to that use case, so you don't have to write a system prompt from a blank page.
Prefer full control? Choose Custom and write your own system prompt from scratch - the template is just a starting point, never a limit.
Control the AI's Reply in Advance
Edit the complete system prompt in a plain-text editor - identity, instructions and constraints are all yours to write, exactly as you'd word them, with no hidden template locking you in.
Every template - and every custom prompt you write from one - keeps a set of built-in constraints: the Chatbot never reveals its knowledge base or instructions, only answers from retrieved content, and won't adopt a new role no matter what a visitor asks it to do.
What Happens When Your AI Chat Doesn't Know the Answer?
Write your own fallback message for the moments when the Chatbot genuinely doesn't have an answer - so instead of a generic, robotic error, your visitors get a message in your own voice.
A good fallback message can suggest a next step - a related topic, a way to contact your team - turning a dead end into a still-useful conversation.
The Chatbot Won't Be Tricked

When a visitor tries to knock the Chatbot off its role - for example asking it to adopt a different persona, or to reveal its system prompt - the artificial intelligence behind it doesn't fall for it. Every template, and every custom version built from one, carries the same built-in constraints: it never reveals its instructions, its training data, or its Knowledge Base, and it never switches identity, no matter how cleverly the request is worded.
This protection isn't a separate filter bolted on afterward - it's built into how every answer is generated: before replying, the artificial intelligence combines your system prompt with the relevant content retrieved from your Knowledge Base, and answers only from that. So the Chatbot stays true to both your brand and your actual content - no guessing, no role-play.
