AI Models
Four models. One choice.
Pick the model that fits your use case. Switch at any time, no retraining needed.
GPT-4o Mini
The default model. Quick responses, low cost, and surprisingly capable for most support and FAQ use cases.
GPT-3.5 Turbo
Proven and consistent. Good at following precise instructions, especially useful when you need predictable answers.
GPT-4o
The best balance of intelligence and speed. Handles nuanced questions, longer context, and complex knowledge bases.
System Instructions
Write the rules.
The AI follows them.
A system prompt is a set of instructions your chatbot reads before every conversation. It sets the role, tone, and limits.
Only answer questions about Acme products and services.
// If the answer isn't in your knowledge base, say:
"I'm not sure about that, please contact us at support@acme.com."
Be friendly and concise. Never mention competitors.
Response controls
Tune how the AI responds
Temperature
Controls randomness. Low temperature = consistent, predictable answers. High temperature = more varied and creative responses. For support use cases, keep it low (0.3–0.5). For creative or conversational bots, try 0.7–0.9.
Max Tokens
Limits how long the AI's responses can be. One token is roughly ¾ of a word. For short, punchy answers, like a chat widget, 250–500 tokens works well. For detailed explanations, go higher.
Prompt templates
Start from a template
Pick a pre-written prompt for your use case and customise from there.
Best practices
What makes a good
system prompt?
Four things every well-configured chatbot has in its instructions.
Give it a name and a role
Start with: "You are [name], a [role] for [company]." This anchors every response. Vague personas give vague answers.
Define what it should NOT do
Add a "never" line: "Never discuss competitors. Never give legal advice." Guardrails prevent off-topic responses.
Set the tone explicitly
"Be friendly but concise" or "Be professional and formal." Don't assume the AI will guess the right tone for your brand.
Handle the unknown gracefully
Tell it what to say when it doesn't know: "If you're unsure, say so and ask the user to contact support." Honesty builds trust.
Use case examples
Real prompts for real results
Resolve 80% of questions before they hit your inbox
Cover returns, shipping, FAQs, and account questions automatically. The AI stays on-topic and knows when to hand off.
Collect name and email before diving into detail
Every visitor who starts a chat becomes a captured lead, even if they leave without buying.
Help shoppers find the right product, fast
Guide visitors from question to the right product page. Reduce bounce rate on category pages.
Good vs bad config
The difference is in the details
Most chatbots fail because of vague instructions, not bad AI. Here's what that looks like in practice.
