AI Chat AssistantSite owners and developers

Install and secure the AI chat widget

Allow the website domain, copy the bot-specific snippet, and diagnose a missing widget.

In the app→My Bots → select bot → Widget, then Embed

Install

  1. 1

    Add the exact website domain to Allowed Domains. Include a wildcard only when subdomains should also load the widget.

  2. 2

    Open Embed and copy the script containing the bot public token.

  3. 3

    Paste the script immediately before the closing body tag on the required pages.

  4. 4

    Clear site and CDN caches, then test in a private browser window.

<script
  src="https://app.k2mailer.com/widget/assistant.js?v=3"
  data-bot="YOUR_BOT_PUBLIC_TOKEN"></script>

If the widget does not appear

  • Confirm the bot is active.
  • Confirm at least one file or URL has completed indexing.
  • Confirm the page hostname matches an allowed domain.
  • Check that a content-security policy is not blocking the widget script or API requests.
  • Check the browser console and network panel for domain, token, CORS, or rate-limit errors.
