Before you start
Before you start you need one thing: the address of your website.
No card, no account setup questionnaire, nothing to install first.
Step by step
Paste your website address. The agent reads your pages and writes its own role, tone and greeting, and collects your content as its knowledge.
Look over what it produced. The role, the tone, the answer length, the welcome message and the suggested questions are all editable. Change what you disagree with.
Add anything the site does not say. Files, a few question and answer pairs, and any rules about what it should always or never do.
Pick a theme and adjust the colours so it matches your site.
Copy the code and paste it into your site. Platform-specific instructions are linked below.
