Agents

An agent is a single chatbot. You can run several — one per site, course, product, or audience — each with its own prompt, knowledge, look, and limits.

The system prompt

The system prompt is the agent's standing brief. It is read before every conversation and shapes tone and scope. Good prompts are specific:

State who the agent is and who it serves ("You help students of Intro to Optimisation").
List what it should do, and what it should refuse or defer.
Set the tone (concise, formal, friendly).

You do not need to tell the agent what language to use. It detects the visitor's language from the question and answers in kind.

Choosing the answer quality

On most plans you pick a quality tier rather than a raw model:

Base — fast and economical, the right default for most assistants.
Premium — a stronger model for harder reasoning. A Premium reply draws more from your monthly message allowance than a Base reply.

Where a tier supports extended thinking, the form shows an "extended thinking" hint. On the BYOK and Custom plans you instead pick the exact model and sampling settings yourself.

Reasoning

Some models can "think" before answering. When reasoning is available you can enable it for an agent, and optionally show the thinking to visitors as a collapsible "Thinking…" panel. When hidden from visitors, the reasoning is still kept for your own review in the conversation diagnostics.

Citations and moderation

Citations — when an agent is grounded in a library, it can show the sources behind each answer. Toggle this per agent.
Moderation — a built-in safety shield is always on. You can opt into additional categories for stricter filtering.

Managing agents

Edit an agent any time; changes apply to new messages immediately. Deleting an agent removes it and stops its embed from working, but never touches your conversation history or libraries.
