The story behind this plugin

Every AI chat plugin on WordPress right now wants your money. $29/month here, $49/year there. "Free tier" that caps you at 100 messages then locks you out. Proprietary SaaS platforms that store your customer conversations on their servers, behind their paywall, under their terms.

Your visitors' data. Your API key. Their profit.

We looked at this and thought — why?

You already pay for your hosting. You already pay for your API key. Why are you paying a middleman to connect the two? Why does a plugin that literally proxies API calls need a $29/month subscription?

It doesn't.

SiteChat AI is the answer. One plugin. Zero subscriptions. Your server. Your keys. Your data. Your rules.

And it's free. Not "free trial." Not "freemium." Not "free for 14 days." Free. Today, tomorrow, forever. Because the WordPress community deserves better than what it's been given.

API keys never leave your server. The browser talks to WordPress. WordPress talks to the LLM. Your visitors never see your keys. No third-party SaaS ever touches your data.

Add your own LLM provider in 20 lines

The whole point of this plugin is that you are in control. Want to connect a new provider? Here's everything you need:

<?php
class My_Provider implements SiteChat_AI_Provider {

    public function get_id(): string    { return 'my_provider'; }
    public function get_name(): string  { return 'My Custom LLM'; }

    public function generate_response( array $messages, array $settings = [] ): string {
        $response = wp_remote_post( 'https://my-llm-server.com/v1/chat', [
            'body'    => wp_json_encode( [ 'messages' => $messages ] ),
            'headers' => [ 'Content-Type' => 'application/json' ],
        ]);
        $body = json_decode( wp_remote_retrieve_body( $response ), true );
        return $body['choices'][0]['message']['content'] ?? '';
    }
}

// Register it. Done. It shows up in the admin dropdown immediately.
add_filter( 'sitechat_ai_providers', function( $providers ) {
    $providers['my_provider'] = new My_Provider();
    return $providers;
});

That's it. No config files. No build steps. One filter hook and your provider is live.
