You bring your own AI key
Chatzio does not include or resell AI usage. You create a free or paid account at OpenRouter, generate an API key, and paste it into the plugin settings. All AI requests are billed to your OpenRouter account. Messaging is unlimited on the free plugin.
Chatzio Pro (optional add-on)
The free plugin is fully functional on its own. The optional Chatzio Pro add-on (from https://chatzio.pro) adds premium tooling and integrations:
- Live WooCommerce order tracking inside chat
- Back-in-stock (“Notify me”) restock notifications
- Automatic content sync, AI embeddings and semantic knowledge search
- Resource Library (PDF / Word upload)
- Advanced analytics (heatmap, intent, funnel)
External services
This plugin connects to the OpenRouter API (https://openrouter.ai) to generate chat replies. OpenRouter is a third-party AI gateway.
- What is sent and when: When a visitor sends a message in the chat widget, the plugin sends that message and recent conversation history from the same chat session to OpenRouter so the AI can generate a reply. Each request also includes your site URL and site title in the request headers (used by OpenRouter for attribution).
- Authentication: Requests are authenticated with the OpenRouter API key that you enter in the plugin settings. No requests are made until a key is configured.
- Nothing is sent until used: No data is sent to OpenRouter on install or activation, only when the chat is actually used.
Your use of OpenRouter is subject to their terms and privacy policy:

FAQ
-
Do I need an API key?
-
Yes. Chatzio uses your own OpenRouter API key so that AI usage is billed to your account and your data stays under your control. You can get a key at https://openrouter.ai/.
-
Does it work with WooCommerce?
-
Yes. When WooCommerce is active, Chatzio shows product cards, product recommendations, and an “add to cart” action. Live order tracking in chat and back-in-stock (“Notify me”) restock notifications are part of the optional Chatzio Pro add-on.
-
Is any data sent to third parties?
-
Only to the OpenRouter API you configure, and only when the chat is used. See the “External services” section above for details.
-
Where is chat data stored?
-
Conversations, leads and analytics are stored in your own WordPress database. You can set a data-retention period in the settings to automatically delete old records.
