Costello AI Chat

Costello is an AI receptionist that qualifies leads and answers questions in real time via a chat widget on your site.

This plugin injects the Costello widget script on every page of your site. No coding required — click Connect to Costello, approve, and you’re live.

Features:

• One-click connect — link your Costello account with a single button, no copy-pasting.
• Enable / disable toggle without touching any code.
• Works with any theme.
• No build step, no dependencies.

Getting started:

1. Install and activate this plugin.
2. The Settings → Costello Chat page opens automatically.
3. Click Connect to Costello and approve the connection. Your widget goes live instantly on every page.

Prefer to do it by hand? You can paste your Agent ID manually instead — find it in your Costello dashboard under Integrations → Chat Widget.

External services

This plugin connects your site to Costello, an external AI chat service operated by Costello, to provide the live chat widget. A Costello account is required to use the plugin.

The plugin relies on the Costello service in two ways:

• Loading the chat widget. On every front-end page, the plugin loads the widget script from https://platform.costellohq.com/widget/v1.js, tagged with your Agent ID. When a visitor opens the chat, their messages are sent to Costello to generate replies. The conversation data visitors enter (such as their questions, name, or contact details) is processed by Costello.
• Connecting your site. When you click “Connect to Costello”, the plugin sends your site’s URL to https://platform.costellohq.com/connect/wordpress so you can approve the connection and receive your Agent ID. No data is sent to Costello until you actively connect or a visitor uses the widget.

Use of the Costello service is governed by Costello’s Terms of Service (https://costellohq.com/terms) and Privacy Policy (https://costellohq.com/privacy).
