Init Live Search is a modern, lightweight, and fully accessible live search solution for WordPress — now with tag-aware matching, SEO metadata support, ACF integration, WooCommerce product filters, and customizable UI presets.

Perfect for content-heavy blogs, WooCommerce stores, or even headless sites. Every interaction is fast, fluid, and designed to work across devices.
It also brings AI-powered related posts and an advanced keyword generator — giving your visitors smarter ways to discover content.
