<h3>External Services</h3>
This plugin connects to an API provided by Cohere (https://cohere.com) to perform AI-powered filtering of WordPress posts and custom post types. It sends the prompt entered by the admin to Cohere’s <code>/v2/chat</code> endpoint. The API responds with a set of WP_Query arguments based on understanding of the prompt.
<h3>Details of the API integration</h3>
<ul>
<li>
What the service is: 
The plugin integrates with the Cohere Chat API (https://cohere.com), a third-party AI service that specializes in natural language understanding and generation.
</li>
<li>
What it is used for: 
The API is used to analyze admin-entered prompts and return relevant WP_Query arguments. These are used by the plugin to filter posts or custom post types intelligently, enabling semantic searching in the WordPress admin area.
</li>
<li>
What Data is Sent:
<ul>
<li>The prompt entered by the WordPress admin is sent to the Cohere API. No personal user or customer data is collected or transmitted.</li>
</ul>
</li>
<li>
Why the data is sent: 
The data is sent so that the Cohere API can understand the context of the content and the user’s intent behind the prompt. This allows it to return accurate WP_Query arguments to filter posts, instead of relying on simple keyword-based filters.
</li>
<li>
When Data is Sent: 
Only when the admin enters a prompt in the plugin interface and initiates the filter action
</li>
<li>
How Data is Sent: 
Data is sent via a secure <code>wp_remote_post()</code> request to <code>https://api.cohere.com/v2/chat</code>
</li>
<li>
Terms and Privacy:
<ul>
<li><a href="https://cohere.com/terms-of-use" rel="nofollow ugc">Cohere Terms of Use</a></li>
<li><a href="https://cohere.com/privacy" rel="nofollow ugc">Cohere Privacy Policy</a></li>
</ul>
</li>
</ul>
This API connection is essential for the plugin’s AI features to function. If you choose not to use the AI filtering functionality, the rest of the plugin remains functional.

WCAPF – Ajax Product Filter for WooCommerce


Purchased the pro version but realised it didn't have the feature I was looking for, so I requested for a full refund. However, I only got a partial refund because the seller said that they will not refund the gateway fee. It is not fair to consumers because it wasn't stated anywhere else on the website when I purchased. In the T&C page it also mentioned full refund without any clause.



Those interested can go to archive.org to find their T&C page in case they updated it.


No Full Refund


I tested recently most of the filter plugins and many of them have problems with product ordering, pagination and "and/or" relations. WCAPF was the only solution that covers al the problems I had before. Even the free version is much more powerful than most over the other premium solutions.



Mainul, keep up the great work!
