KOZ SEO Core generates document titles, meta descriptions, canonical URLs, robots directives, Open Graph and Twitter metadata, JSON-LD schema, hreflang links and WordPress sitemap controls.
It also provides /llms.txt, /.well-known/koz-ai-manifest.json, a read-only inventory of other SEO plugins and a limited accessibility audit. Existing settings and post metadata from the former UA FREE package remain in place and are reused automatically.
The plugin was originally developed for the UA FREE charitable foundation website, which remains a production environment for the suite. The software is independently owned and maintained by Tony Kozyriev (ramirkz).
Part of the KOZ Suite
KOZ SEO Core is one focused module of the broader KOZ Suite, a family of independent WordPress plugins that share a common KOZ administration experience and visual identity.
Each KOZ plugin remains independently installable, so site owners can use only the modules they need or combine several modules into one toolkit.
Current public KOZ plugins:
- KOZ SEO Core — technical SEO, schema, sitemaps, AI discovery and OpenAI Vision image ALT.
- KOZ Copy Actions — accessible copy-to-clipboard actions for selected WordPress content.
- KOZ URL-Only Comment Spam — privacy-first local moderation for URL-only comment spam.
- KOZ Static Translate — AI-powered multilingual translation with Microsoft Azure AI Translator and static language routes.
- KOZ Translate Diagnostics — read-only health checks and privacy-safe diagnostic reports for KOZ Static Translate.
- KOZ 404 Guard & URL Intelligence — privacy-safe 404/410 diagnostics, controlled same-site redirects and URL intelligence.

External services
The optional AI Vision ALT workflow uses the WordPress 7.0 AI Client with the OpenAI provider configured by the site administrator under Settings Connectors. KOZ SEO Core does not store an OpenAI API key.
Only when an administrator explicitly starts AI Vision analysis, the selected image file and a short prompt that may include the parent page title are sent through the configured OpenAI connector for image analysis. No visitor data is sent by this feature. The rest of KOZ SEO Core works without this service.
