Security & Privacy

What data moves, what stays local.

WP Chat AI connects your WordPress site to OpenAI using your API key. Potent Pages does not receive or store visitor questions, conversations, API keys, usage logs, or rate-limit data from the plugin.

Website content sent to OpenAI

To answer questions, WP Chat AI may send relevant excerpts from your WordPress posts, pages, configured business context, and indexed content to OpenAI as prompt context. Content may also be sent to OpenAI when embeddings are generated for site search.

Visitor questions sent to OpenAI

Visitor questions are sent to OpenAI so OpenAI can generate a response. The plugin uses your OpenAI API key, so those requests belong to your own OpenAI account.

Local conversation storage

Chat conversations are stored locally by the plugin on your WordPress site. They are available to you through your site and are not transmitted to Potent Pages.

No Potent Pages visitor data collection

WP Chat AI itself does not send visitor data, chat history, API keys, or usage records to Potent Pages.

API key protection

Your OpenAI API key is stored in your WordPress database as a plugin setting. Access should be limited through normal WordPress administrator permissions, secure hosting, database access controls, and HTTPS for admin sessions.

Rate limiting identifiers

The plugin uses visitor IP addresses or related request identifiers locally to enforce per-minute and per-hour rate limits. This helps reduce abuse and control OpenAI API costs.

No plugin telemetry or tracking

The plugin does not include third-party analytics, telemetry, advertising pixels, or tracking scripts.

Your OpenAI account terms apply

Because AI requests are made through your OpenAI account, OpenAI’s API policies, data handling, and billing terms apply to the content and questions sent to OpenAI.

Questions

Frequently asked questions.

Key details about compatibility, pricing, customization, performance, and content retrieval.

Will this work with my WordPress theme?

WP Chat AI is designed to work across WordPress themes without disrupting the existing page layout.

Is the plugin really free?

Yes. The plugin itself is free to install and use. OpenAI API usage is separate and requires funds in your OpenAI account.

Do I need an OpenAI API key?

Yes. The plugin uses OpenAI’s API to generate chatbot responses, so your own API key must be entered in the settings.

How does it find relevant answers?

The plugin retrieves the five most relevant posts or pages from your site and provides that content to OpenAI as context for the response.

Can I customize the chatbot?

Yes. You can customize the title, colors, initial message, additional context, transition delay, and default open or closed state.

How does rate limiting work?

You can restrict requests per minute and per hour based on the visitor’s IP address, helping prevent excessive usage and unexpected costs.

Will the chatbot slow down my site?

The response generation runs through OpenAI’s API, while embedding-based search is used to locate relevant content efficiently. The plugin is designed to minimize its effect on normal site performance.

What happens when my API balance runs out?

The chatbot will stop generating answers until more funds are added to the connected OpenAI API account.

Can I add information beyond my page content?

Yes. Additional context can be attached to each query, including product details, service descriptions, policies, or promotional information.

Does WP Chat AI send data to Potent Pages?

No. Plugin usage data, conversations, API keys, and rate-limit records stay on your WordPress site and are not sent to Potent Pages.

Install WP Chat AI and give visitors a direct, conversational path to the information already available on your WordPress site.
