What is a WordPress AI chatbot plugin?
A WordPress AI chatbot plugin adds an AI assistant to a WordPress site from the WordPress admin, without editing theme files. The assistant answers visitors' questions from the site's own content.
Aivastark's plugin needs one setting, your Widget Key. The agent it loads is trained on your site, answers in 80+ languages, and hands the conversation to your team when a visitor asks for a person.
What Aivastark does on WordPress
One field
Paste your Widget Key and save. The agent is live on every front-end page.
Site-wide or per page
Leave the key empty and use a shortcode to load the widget only where you want it.
Customise inside wp-admin
Connect the plugin to your account and adjust the widget without leaving WordPress.
What the plugin does
Install once, live on every page
Paste your Widget Key in the plugin's settings and the agent loads on every front-end page. Prefer a few pages? Use the shortcode instead.
- Shortcode for a single page: [aivastark key="YOUR_WIDGET_KEY"].
- The script loads asynchronously, so it stays out of your Core Web Vitals.

Aivastark → Settings
ExampleLive on every front-end page
Or on one page only
[aivastark key="YOUR_WIDGET_KEY"]Run it without leaving wp-admin
Connect the plugin to your Aivastark account and Aivastark opens as a full-screen app inside WordPress: the Widget editor, Inbox, Knowledge base, Leads and Analytics, already signed in.
- Display rules pick the pages, devices and visitors that see the widget, and how early it loads.
- Your agent's name, colours and persona on every plan; hide the Aivastark badge on Scale; custom white-label arrangements on Enterprise, on request.

Know your logged-in visitors
Turn on “Know your logged-in visitors” and the agent knows which signed-in user it is talking to. The identity is verified with a signature, so a visitor can't pretend to be someone else. Available on Growth and above.

Questions about Aivastark on WordPress
How do I add an AI chatbot to WordPress?
Install the Aivastark plugin from Plugins → Add New and activate it, then paste your Widget Key under Aivastark → Settings and save. The agent appears on every page of the site.
Is the plugin free?
Yes. The plugin is free and GPL-licensed, and Aivastark's Free plan is permanent and needs no card. Paid plans start with a 7-day trial.
Do I need an OpenAI or ChatGPT API key?
No. The AI is included in your Aivastark plan; the only thing the plugin needs is your Widget Key.
Does it work with WooCommerce?
Yes. The plugin puts the agent on your store, and you connect WooCommerce separately from the Aivastark dashboard so the agent can read your catalogue and orders.
What are the requirements?
WordPress 5.8 or later and PHP 7.4 or later. The plugin is tested up to WordPress 6.8.
Can I show it on only some pages?
Yes. Leave the site-wide key empty and add the shortcode [aivastark key="YOUR_WIDGET_KEY"] to the pages where the widget should load.
Will it slow down my WordPress site?
No. The widget script loads asynchronously, so it stays out of the critical rendering path.
