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.
