Voice AI for WordPress and WooCommerce

Vocalia and Zellia turn your website into something visitors can talk to — out loud, in real time.

Vocalia works on any WordPress site. It answers questions, guides visitors to the right page, and books appointments — all by voice.

Zellia is built for WooCommerce. It helps shoppers find products, filters your catalogue, adds items to the cart, and looks up order tracking — like a salesperson who never sleeps.

Both run on your own OpenAI key. You pay OpenAI directly for what you use. We never add a markup.

2. How it works

It’s a conversation, not a chatbot.

Most WordPress AI plugins are text chatbots: the visitor types, the bot replies with text. Vocalia and Zellia are different — the visitor speaks, and the agent speaks back, naturally, in real time.

And it doesn’t just talk. It acts on your site: opens pages, filters products, adds to the cart, checks an order. The conversation does the work.

Bring your own OpenAI key (BYOK).

You connect your own OpenAI API key. Conversations go straight from your visitor’s browser to OpenAI using that key. This means:

  • You pay OpenAI directly — we take no cut of your usage
  • Your data isn’t routed through a third-party platform
  • You stay in control of your own account and costs

Most small sites spend just a few dollars a month on OpenAI.

3. Requirements

Before you start, you’ll need:

  • A WordPress site (for Zellia, WooCommerce installed and active)
  • An OpenAI account with an API key
  • A Vocalia or Zellia license (or both)

No servers to manage, no coding required. If you can install a plugin and paste two keys, you can run this.

4. Getting started

Four steps to a working voice agent:

  1. Install the plugin. Download the ZIP from your welcome email, then in WordPress go to Plugins → Add New → Upload Plugin.
  2. Activate your license. Paste the license key from your email into the plugin settings.
  3. Connect OpenAI. Paste your OpenAI API key. This is what powers the voice.
  4. Describe your agent. In plain language, tell the agent how it should behave — its name, its tone, what it should help with. No code.

That’s it. Your agent is live on your site.

Once installed, each plugin includes full in-app documentation with a searchable guide covering every feature — appointments, product actions, order tracking, multi-agent setups, and more.

5. Vocalia — what it does

Vocalia is your voice agent for any WordPress site:

  • Answers questions using a knowledge base you control
  • Guides visitors to the right page by voice
  • Books appointments — checks availability in your Google Calendar, reserves the slot, sends the invite
  • Speaks any language — lock it to one, or let it follow the visitor
  • Multiple agents — run different agents on different pages

Full setup steps for appointments, the knowledge base, and multi-agent configuration are inside the plugin’s documentation.

6. Zellia — what it does

Zellia is your voice agent for WooCommerce:

  • Finds products by voice — «show me summer bags under 200»
  • Filters and sorts your catalogue visually as it talks
  • Adds to cart and guides the shopper to checkout
  • Tracks orders — the customer asks «where’s my order?» and gets an answer
  • Captures customer details so you can follow up

Full setup steps for shopping actions and order tracking are inside the plugin’s documentation.

7. Troubleshooting

The agent shows an error / says keys are missing.
Open the plugin’s Test Connection tool. It tells you exactly what’s missing — usually the license key or the OpenAI key. Make sure the license key matches the one in your welcome email exactly.

I updated the plugin and it stopped connecting.
Updating never deletes your settings — they’re stored safely in WordPress. If it disconnects, check that your license key is still the correct one from your email.

The agent replies in the wrong language.
In the agent settings, you can lock it to a specific language or let it follow whatever the visitor speaks.

Appointments or order tracking aren’t working.
These need a Google setup with a Sync Secret. Follow the step-by-step guide inside the plugin — it walks you through it and includes a test button to confirm the connection.

8. Frequently asked questions

Do I need an OpenAI account?
Yes. Both plugins run on your own OpenAI API key — see How it works. You pay OpenAI directly for what you use, and we never add a markup. Most small sites spend just a few dollars a month.

What’s the difference between Vocalia and Zellia?
Vocalia works on any WordPress site: it answers questions, guides visitors, and books appointments. Zellia is built for WooCommerce: it searches your catalogue, filters products, adds to cart, and tracks orders. See Vocalia and Zellia for the full breakdown.

Is this a chatbot?
No. Your visitor speaks and the agent speaks back, in real time — and it takes actions on your site rather than just replying with text. More on this under How it works.

Do I need to know how to code?
No. Install the plugin, paste your license key and your OpenAI key, and describe how the agent should behave in plain language. The four steps are in Getting started.

What languages does it support?
You can lock an agent to a specific language, or let it follow whatever language the visitor speaks — automatically.

Does it work with my theme or page builder?
Yes. The agent runs as an overlay on your site, independent of your theme, so it works with any WordPress theme or builder.

How much does OpenAI cost me?
It depends on usage, but most small sites spend only a few dollars a month. Because you use your own key, you see and control those costs directly in your OpenAI account — we never touch them.

What happens to my data?
Conversations go straight from your visitor’s browser to OpenAI using your key. We don’t store transcripts. Your OpenAI key is encrypted on our server and never saved in your WordPress database.

Something isn’t working — where do I start?
Open the Test Connection tool inside the plugin; it tells you exactly what’s missing. Common fixes are in Troubleshooting, and each plugin includes a full searchable guide.

Is there a refund policy?
Yes — 60 days, no questions asked.
