Model and behavior settings

Your chatbot’s Settings section (under Advanced in the sidebar) controls the machinery behind answers. Most chatbots work well on the defaults; this page explains each knob for when you need it.

Settings → General

Setting	What it does
Description	An internal note about this chatbot, for your team.
Support Email	The reply-to address on emails SiteGPT sends to your visitors (like OTP verification). Falls back to your account email. Escalation and lead notification recipients are set in Human Support and Leads Settings.
GPT Model	The model that writes answers: GPT-4.1 Mini (default, fast) or GPT-4.1 (strongest). GPT-4.1 answers draw from your GPT-4.1 message quota; see Usage.
Number of History Messages To Be Considered	How many previous messages the chatbot re-reads when answering. Raise it for long, multi-step conversations; keep it low for one-shot Q&A.
Limit Messages Per Conversation and Max Messages Per Conversation	Cap a single conversation’s length. Useful against abuse and runaway usage.
Enable Page Context Awareness	Lets the chatbot know which page of your site the visitor is on, so “does this apply here?” style questions work.
Disable lead notifications	Stops the email that is sent for each new lead.
Disable smart follow up questions	Turns off AI-generated follow-up suggestions. See followups.

Settings → Advanced

Setting	What it does
TopK	How many passages of your content are retrieved per answer. Raising it gives the model more material at the cost of focus.
CSS Selectors	Site-wide default selectors to strip when crawling, for example `header, .footer, #nav`. Changes apply when links are retrained. Per-import selectors are in scrape options.

Chat modes

Settings → Chat Modes decides who answers first:

AI: the chatbot answers, and visitors can escalate to your team when human support is enabled.
Agent: every conversation starts with a human; the AI stays out of the way. Use this when you want SiteGPT as a plain live-chat inbox.

You can also take over any single conversation as a human from Chat History, whatever the mode.

Webhooks

Settings → Webhooks sends conversation events to your own endpoints, on plans and add-ons that include webhooks. See Webhooks for payloads and setup.

Danger zone

Delete Chatbot at the bottom of Settings permanently removes the chatbot, its content, and its conversations. See Delete your chatbot.
