## 説明

[Costello](https://costellohq.com) 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](https://platform.costellohq.com/app) 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).

## インストール

 1. In your WordPress dashboard, go to **Plugins  Add New** and search for “Costello”.
    Click **Install Now**, then **Activate**. (Or upload the `costello-ai-chat` folder
    to `/wp-content/plugins/` manually.)
 2. The **Settings  Costello Chat** page opens automatically after activation.
 3. Click **Connect to Costello** and approve — your widget goes live instantly. Prefer
    to do it by hand? Paste your Agent ID into the manual field instead.

## FAQ

### Where do I find my Agent ID?

Log in to [platform.costellohq.com](https://platform.costellohq.com/app), go to **
Integrations  Chat Widget**, and copy the Agent ID shown on the page.

### Can I disable the widget without uninstalling the plugin?

Yes. Go to **Settings  Costello Chat** and uncheck the **Widget status** checkbox,
then save.

### Does the widget load on every page?

Yes. The script is injected into `wp_footer` globally so it appears on all front-
end pages.
