Sernicola Labs AI Friendly – llms.txt, Markdown & Schema

Sernicola Labs AI Friendly is a GEO/AEO content publishing toolkit, not only an llms.txt generator. It combines machine-readable content, selective publishing controls, versioned output, and semantic identity in one local WordPress workflow. The plugin provides:

• Dynamic /llms.txt generation.
• Public .md endpoints for published content.
• Optional static Markdown files with regeneration workflows.
• Inclusion and exclusion rules for post types, taxonomy terms, templates, URL patterns, and noindex/password conditions.
• Admin tools for preview, snapshots, diagnostics, and bulk operations.
• WooCommerce Product schema completion for Google merchant listings: brand, shipping details, return policy, and price validFrom.
• Automatic Event, Course, and Service schema for any post type, mapped from custom fields, ACF, taxonomies, or fixed values, with per-post overrides.
• Optional Semantic Schema JSON-LD layer with multi-type organizations, related publications, event series, brands and sub-organizations, repeatable contacts, Place/Geo, opening hours, certifications, generic identifiers, automatic Breakdance FAQPage, WordPress-powered OfferCatalog sources, and Yoast/Rank Math graph extension.
• Local-first operation without external API calls, subscriptions, analytics, or transmitted usage data.
• Automatic migration of settings, content exclusions, custom schema, and snapshots from AI Friendly versions prior to 2.1.

Privacy AI Friendly does not contact external services and does not transmit analytics or usage data. Its activity log is stored only in the local WordPress database, contains technical events without user identifiers, and retains at most 200 entries. Optional regeneration emails are sent through the site's configured WordPress mail system only when enabled by an administrator. ACF field extraction is disabled by default. Enable it only when the text values of all ACF fields attached to included content are intended for public .md output. When the plugin is deleted from WordPress, its settings, activity log, generated files, snapshots, scheduled events, and plugin-specific post metadata are removed.

1. Upload the plugin zip from Plugins > Add New > Upload Plugin.
2. Activate the plugin.
3. Open Settings > AI Friendly.

When moving from the old ai-friendly package, leave it installed and activate sernicola-labs-ai-friendly. The new plugin imports the available data and safely deactivates the old version. The temporary Content Hub summary disappears automatically after an error-free regeneration and removal of the old plugin. A network-active legacy copy is deactivated automatically only when the new plugin is network-activated too.
