Publicator AI
Publicator AI is an AI-powered content marketing platform that researches keywords, writes SEO-optimised articles in your brand voice, and publishes them straight to your WordPress site on a schedule you control. This is the official WordPress companion plugin. Once you install it and connect your site to your Publicator AI project, every piece of content you approve in the Publicator AI dashboard appears on your blog automatically — fully formatted, with the right categories, tags, featured image and SEO meta tags already in place. No copy-pasting. No CMS context-switching. No broken HTML. Why use Publicator AI? Most WordPress site owners juggle a separate AI writer, an SEO plugin, an image generator and a copy-paste workflow. Publicator AI replaces that loop with a single platform that: Researches what your audience is actually searching for and turns it into a content plan you can edit. Writes long-form articles that match your brand voice, tone and length preferences. Generates or sources featured images so every post ships ready to publish. Publishes directly to WordPress via this plugin — instantly or on a future schedule. Keeps your taxonomies in sync so the AI knows which categories and tags actually exist on your site. Writes the SEO meta (title, description) and hands it to Yoast, Rank Math or All in One SEO automatically. What this plugin does Connects your WordPress site to your Publicator AI project with a single sign-in flow, or by pasting an API key copied from your Publicator AI dashboard — pick whichever fits your account type. Receives finished posts from Publicator AI and creates them as native WordPress posts (status: published or scheduled). Re-publishes updates idempotently using an external ID, so re-running a publish never duplicates content. Sideloads the featured image into your Media Library with proper alt text. Resolves and creates categories and tags on the fly, and syncs the full taxonomy back to Publicator AI on demand. Writes SEO title and meta description into Yoast SEO, Rank Math or All in One SEO automatically — whichever you have active. Exposes a small, locked-down REST API namespace (publicator-ai/v1) authenticated with a project-scoped key — no Application Password or admin credentials are ever sent over the wire after the initial setup. Ships a clean, modern settings screen — no buried admin pages, no clutter. Security All requests to the Publicator AI platform go over HTTPS to our Supabase Edge Functions. The plugin stores only a session token and a project-scoped API key. Your Publicator AI account password is never stored. Inbound REST requests are validated with a hashed-comparison check against the per-project API key. Deactivating the plugin tells the Publicator AI platform that the connection is offline, so scheduled posts can pause cleanly. Who is it for? Content teams running AI-assisted publishing at scale. SEO agencies managing multiple client sites who want one dashboard instead of N WordPress logins. Solo bloggers and SaaS marketing teams who want a steady cadence of well-optimised content without hiring a full editorial team. More information and full documentation: https://publicator.ai/ External Services This plugin connects to external services to provide its functionality. By installing and activating the plugin, you agree to the following: 1. Publicator AI (https://publicator.ai/) The core service this plugin integrates with. Used for authentication, project management, content publishing, and taxonomy synchronisation. Privacy Policy: https://publicator.ai/privacy-policy Terms of Service: https://publicator.ai/aszf Cookie Policy: https://publicator.ai/cookie-policy 2. Supabase (https://supabase.com) Publicator AI uses Supabase as its backend infrastructure. The plugin communicates directly with Publicator AI’s Supabase Edge Functions (https://wfjirakgiglsowunllsq.supabase.co/functions/v1/) to handle authentication, project data, and taxonomy synchronisation. No Supabase credentials are stored in the plugin — the Edge Functions handle all authentication internally. Data sent, and when: Administrator email address and password — sent once during sign-in. Credentials are not stored by the plugin; only the returned session tokens are stored in the WordPress options table. WordPress site URL and plugin version — sent when an administrator connects a project. Category and tag names, slugs and IDs — sent when an administrator manually triggers a taxonomy synchronisation. Connection status (connected / disconnected) — sent on connect and disconnect. Theme appearance settings (colours, fonts, font sizes, content width, button radius) — detected from the active theme and sent to Publicator AI, either automatically (to pre-fill personalisation) or when an administrator reviews and approves them via the “Synchronize appearance” button. These describe the theme’s design tokens only; no visitor or personal data is included. No data is sent automatically or without a deliberate action by the site administrator. End-user (visitor) data is never collected or transmitted. Privacy Policy: https://supabase.com/privacy Terms of Service: https://supabase.com/terms
