WP Engine is taking a tool it built for its own hosting customers and handing it to the rest of the WordPress world. Smart Search AI, previously locked behind a WP Engine hosting subscription, is now available to any site running WordPress, regardless of who hosts it.
The tool tackles a fairly specific annoyance: keyword search on websites tends to fall apart the moment someone types a question instead of a phrase, or misspells something, or searches using different words than whatever’s actually on the page. Smart Search AI runs on semantic search instead, meaning it tries to match meaning and intent rather than exact wording, so a visitor typing a loosely worded question still has a decent shot at finding what they’re actually looking for.
There’s a business case underneath the usability pitch, too. People who use a site’s search bar are engaging far more actively than someone just browsing around, and WP Engine says that intent runs two to three times higher for search users. For sites with large or messy content libraries, better search can directly translate into more people actually finding, and acting on, what they came for.
Ramadass Prabhakar, WP Engine’s chief technology officer, called search one of the most overlooked parts of a website’s experience despite how much it actually shapes engagement. Opening the tool beyond WP Engine’s own customer base, he said, is meant to get it in front of a much wider slice of the WordPress community.
On the technical side, Smart Search AI runs on infrastructure separate from the site itself, so it doesn’t slow anything down even as it indexes new content in real time. It works natively with Advanced Custom Fields and WooCommerce, and it also connects to headless WordPress setups through WPGraphQL and REST APIs. There’s an additional piece here worth noting: an MCP server, currently in open beta, that lets site owners expose their live content to external AI agents in a controlled way.
Melanie Clarke, website manager at Mitie, said customer interviews during a recent site redesign turned up a recurring complaint: people simply couldn’t find what they needed and left. She said Smart Search AI changed that pattern noticeably once it went live.
Smart Search AI is available now for any WordPress site.
