Widget & plugins

Add the CatéGPT assistant to any website. Two ways to show the chat — you can use both.

Two modes: a bubble at the bottom of the page, or the chat directly inside a page.

ℹ️

To get a site key, sign in and open the Embed the plugin page. See also the API documentation.

Download the plugins

⬇ WordPress (.zip)⬇ TYPO3 (.zip)⬇ PrestaShop (.zip)

Any site (HTML / other CMS)

A · Floating bubble

<script
  src="https://categpt.chat/embed/widget.js"
  data-site-key="cgpt_site_YOUR_KEY"
  data-language="en"
  data-accent="#c9a227"></script>

Paste this at the very bottom of your pages (just before </body>) or via Google Tag Manager.

B · Embedded chat in a page

<div data-categpt-inline
  data-site-key="cgpt_site_YOUR_KEY"
  data-language="en"
  data-height="600"></div>
<script src="https://categpt.chat/embed/widget.js" defer></script>

Paste this block exactly where the chat should appear.

Attributes

Attribute	Default	Description
`data-site-key`	—	Site key (required).
`data-language`	browser language	fr, en, de, it, es, pt, pl.
`data-accent`	`#c9a227`	Accent colour.
`data-position`	`right`	`right` or `left` (bubble).
`data-height`	`520`	Embedded chat height (px).

“Saint of the day” card (free, no account)

Show the saint and feast of the day (liturgical-colour dot, feast name, short excerpt, link to the day’s page) on any website. Unlike the chatbot, this card is completely free: no site key, no account.

<script src="https://categpt.chat/embed/saint-card.js" data-locale="en" defer></script>
<div data-categpt-saint-card></div>

The <div data-categpt-saint-card> block marks where the card renders; when absent, it is inserted right after the <script> tag. data-locale accepts fr (default), en, de, it, es, pt, pl. The displayed date follows the visitor’s timezone; when the day’s data is unavailable the card simply does not appear.

WordPress

Download the plugin (.zip) above.
In the admin: Plugins → Add New → Upload Plugin, choose the .zip, “Install Now”, then “Activate”.
Open Settings → CatéGPT and paste your site key.
Bubble: tick “Enable the bubble”. Embedded chat: insert the [categpt] shortcode in a page or post.

Shortcode options: [categpt language="en" height="600"].

💡

The WordPress plugin settings are bilingual (French / English) and follow your site’s language. The widget language also follows the site language by default.

TYPO3

Install the categpt extension (.zip above or Composer) and activate it.
Bubble: include the “CatéGPT — Widget” static template in your root template, set plugin.tx_categpt.siteKey in Constants and clear the cache.
Embedded chat: add a “Plain HTML” content element with the embedded chat block above.

PrestaShop

Download the module (.zip) and install it: Modules → Module Manager → Upload a module.
Bubble: click “Configure”, enable the bubble and paste your key.
Embedded chat: create a CMS page, switch to code mode and paste the embedded chat block above.

Security

ℹ️

The publishable key (cgpt_site_…) is locked to the domains you provide: it only works on your sites. For a server-side model, the WordPress plugin can use a secret key (proxy mode) that is never exposed to the browser.

Continuity to categpt.chat

The widget answers concisely and offers to see the full answer and continue the conversation on categpt.chat. The visitor arrives “fresh” (the 3 anonymous questions are not consumed by this handoff).

Billing

Usage-based (prepaid or subscription depending on your contract). Tracking is done in the CatéGPT console.

Privacy

ℹ️

The widget sets no cookie. Questions are kept pseudonymised. The “Powered by CatéGPT” attribution is part of the widget.

Troubleshooting

The widget doesn’t appear. Check that the site key is correct and that your site’s domain is in the allowed origins for that key.

“origin_not_allowed”. The domain the request comes from isn’t allowed for this key — tell the CatéGPT team.

The embedded chat doesn’t show. Make sure both the <div data-categpt-inline> and the <script> tag are present, and that your editor didn’t escape the HTML (use code / HTML mode).

Nothing happens on click. The key may be suspended or the balance depleted — check in the CatéGPT console.
