Sectioneer

Sectioneer adds a curated, theme-aware page-building experience to the WordPress block editor — a section library, one-click insert, and optional AI section generation and editing. It is built entirely on WordPress’s public extension points (SlotFills, block filters, the command palette, the Abilities API and the WordPress AI Client), so it installs as an ordinary plugin and keeps working across core upgrades. It never forks core or replaces the editor.

Open any page or post (or the Site Editor), click the Sectioneer icon in the top-right toolbar, and the Sections panel appears.

Features

• Section library — ready-made sections (hero, features, call to action, and more) with search and one-click insert.
• Theme-aware insert — inserted sections adopt the active theme: raw colors are remapped to the nearest theme.json palette token, so sections never look “pasted in”.
• AI section generation (optional) — describe a section in plain language and Sectioneer generates valid block markup for it, seeded with your theme’s design tokens. Select a block first to revise it in place instead of inserting a new one.
• Safe by construction — all inserted markup (curated or AI-generated) is parsed and rebuilt against registered block types; unregistered or unsafe blocks are dropped.
• One consistent home — every feature lives in a single Sectioneer editor sidebar, in both the post editor and the Site Editor, with a first-run guide so it’s easy to find.

The curated section library works on its own. AI generation is an optional enhancement that degrades gracefully when no AI provider is configured.

AI section generation and external services

Sectioneer does not bundle any AI provider, contain any API keys, or make any external requests on its own. It registers a WordPress Ability and calls it through the WordPress AI Client; the underlying provider is resolved on your own site.

To enable AI generation you install and configure a separate WordPress AI provider plugin (for example AI Provider for Google, AI Provider for OpenAI, or AI Provider for Anthropic) and supply that provider’s API key. When — and only when — you click “Generate”/”Update”, your prompt text and the slugs of your active theme’s design tokens (color and font-size names) are sent to whichever AI provider you configured, via the AI Client running on your site, and the generated block markup is returned. That request is governed by the terms and privacy policy of the AI provider you chose. If no provider is configured, Sectioneer shows a notice and the AI controls are disabled — nothing is sent anywhere.
