Classified Listing by RadiusTheme registers the rtcl_listing custom post type for every listing, with taxonomies rtcl_category and rtcl_location for category and location. Listing details live in wp_postmeta with keys like price, price_type, _rtcl_address, _rtcl_phone, _rtcl_email, _rtcl_website, and per-business hours stored as serialized arrays. Custom fields the admin defines through the plugin's form builder land in postmeta under their configured slugs.

SleekAI maps the rtcl_listing post type, both taxonomies, and the meta keys into the chatbot's system message. A visitor asking for plumbers in a specific city gets a filtered list with business hours, phone numbers, and pricing pulled live. The bot recognizes the price_type values (fixed, on call, negotiable) and answers accordingly. Listings marked as sold via the Mark as Sold feature are filtered out by default.

Generic chatbots can't see the rtcl_listing post type or its custom fields. They miss business hours, custom field data per category (like make/model for cars or bedrooms for real estate), and the dual-taxonomy structure. SleekAI's display conditions let you ship one bot on the listings archive and another on single listing pages, each with its own scope.

Classified Listing by RadiusTheme is one of the most flexible directory plugins on WordPress, supporting classifieds, business directories, real estate, cars, jobs, and service listings from a single rtcl_listing post type. That flexibility creates a chatbot opportunity: visitors landing on a directory site rarely know which filter combination produces the listings they want. A natural-language bot fixes that, but only if it can actually read the rtcl_listing rows, the dual rtcl_category and rtcl_location taxonomies, custom-field data per niche, and the serialized business-hours arrays.

SleekAI maps all of it directly. Buyers ask in plain English for businesses open right now, cars under a price, or rentals with a custom field value, and the bot returns real matches. Mark as Sold listings get filtered automatically from buyer-intent answers, while sellers see their sold inventory on a dashboard-scoped bot.

The AI-assisted form builder in Classified Listing 5.x means every site has different custom fields, and SleekAI handles that without code changes because it reads whatever slugs you mapped. Display conditions plus multibot let one site run separate bots for cars, real estate, plumbers, and any other niche the directory covers, each with its own scoped instruction. Token usage stays low because buyers ask short factual questions, and bring-your-own-key keeps directory operators in control of model and spend.
