Specter for WordPress

Edit your whole WordPress site
with any AI, in one pass.

Specter pulls your WordPress posts and pages down to a folder of local markdown. Now Claude, ChatGPT, Gemini — or your own scripts — can read every post at once, rewrite at scale, and Specter streams the changes back over the WordPress REST API.

◎

Every WP post in one folder

Posts, pages, drafts, scheduled — all as plain markdown files. Any AI you point at the folder sees the whole archive while it edits.

⇄

Block Editor stays out of the way

Edit posts as markdown, not as Gutenberg blocks. Round-trip preserves title, slug, tags, categories, status, dates, featured image, Yoast/Rank Math meta.

Why WordPress operators reach for Specter

The Block Editor is good for one post. You have thousands.

WordPress is the workhorse of the open web — and the most painful platform on this list to run modern content operations on. The Block Editor was built for handcrafted pages, not bulk work. The REST API is comprehensive but times out on long runs. AI plugins paste GPT output straight into the editor with no quality control and no view of the rest of your site. Specter sidesteps all of that: pull your whole site into markdown, point any AI at the folder, and stream the changes back over the REST API in the background.

What you can do

The bridge between WordPress and everything else

Specter isn't an AI and it isn't a CMS. It keeps your live WordPress site and a folder of local markdown perfectly in sync — so every other tool you own can finally reach your content, all of it, at once.

◎

Full-archive context for AI

Every WordPress post and page lives in one folder of plain markdown. Point Claude, ChatGPT, or Cursor at that folder and the AI sees every post at once — so it can weave accurate internal links and match your tone across the whole site.

⚡

Bulk operations that don't crash

Run an AI pass across thousands of posts — rewrite intros, fix product mentions, regenerate Yoast/Rank Math meta, swap CTAs. Specter streams the result back through the WP REST API without timing out.

⇆

Migrate to or from WordPress

Specter speaks the same markdown to WordPress, Ghost, and Shopify. Pull from WP and push to Ghost (or vice versa) by changing where the same folder syncs.

✦

Any AI, no lock-in

Claude, ChatGPT, Gemini, Copilot, your own scripts — they all read the same markdown on disk. Specter is the bridge; you bring the intelligence.

⇄

Two-way sync

Edit locally → Specter pushes. Edit in WP admin → Specter pulls down. Posts round-trip with full frontmatter, tags, categories, status, dates, featured image URL.

👁

Dry-run preview

Preview Sync before you commit. See which WordPress posts would be created, updated, or flagged as conflicts.

🔒

Application Passwords, never your main login

Specter authenticates via WordPress Application Passwords. Stored in the macOS Keychain. Revoke from your WP admin any time.

📁

Plain markdown, no lock-in

Standard YAML frontmatter. Your content stays yours on your disk. Cancel any time and keep every file.

How it works on WordPress

Three steps. No drama.

Generate an Application Password

In WordPress admin: Users → Profile → Application Passwords. Name it "Specter" and copy the password — you'll only see it once.

Paste it into Specter

Open Specter, add a WordPress site, paste your site URL, username, and the Application Password. Specter tests the connection before continuing.

Pick a folder and write

One picker. Each WordPress post and page becomes a markdown file with full frontmatter. Edit in Obsidian or VS Code, or hand the folder to Claude. Save. Specter pushes back.

FAQ

WordPress questions, answered

Does Specter work with WordPress.com?

WordPress.com Business or higher (where the REST API is enabled and Application Passwords work). The free, Personal, and Premium tiers don't expose what Specter needs. Self-hosted WordPress works on any plan — anywhere you control the install.

What about the Block Editor and page-builders?

For standard posts, Specter converts Gutenberg blocks ↔ markdown cleanly. For Elementor, Divi, Beaver Builder, and other page-builder pages, the body comes through as the underlying HTML — Specter doesn't try to round-trip page-builder layouts (they're not really markdown content). Bulk-edit those in the page-builder itself.

Does Specter touch WooCommerce data?

No. Orders, customers, products, inventory, and Stripe are out of scope. Specter syncs posts and pages only. Product descriptions are not currently in scope — that's tracked on the roadmap.

What about Yoast or Rank Math?

The primary SEO fields — meta title, meta description, canonical — round-trip in the frontmatter of each post. Plugin-specific advanced fields (schema overrides, social cards) are not currently synced.

Will Specter overwrite edits made in the WP admin?

Not without asking. Specter flags conflicts (where both you and WordPress changed the same post since the last sync) and shows you both versions. You can set a default if you'd rather not be interrupted.

Does it work with multisite?

Each site in a multisite network is treated as its own connection. Add one Specter connection per network site you want to sync.
