Specter for WordPress
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.

Why WordPress operators reach for Specter
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
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.
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.
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.
Specter speaks the same markdown to WordPress, Ghost, Shopify, and Webflow. Pull from WP and push to Ghost (or vice versa) by changing where the same folder syncs.
Claude, ChatGPT, Gemini, Copilot, your own scripts — they all read the same markdown on disk. Specter is the bridge; you bring the intelligence.
Edit locally → Specter pushes. Edit in WP admin → Specter pulls down. Posts round-trip with full frontmatter, tags, categories, status, dates, featured image URL.
Preview Sync before you commit. See which WordPress posts would be created, updated, or flagged as conflicts.
Specter authenticates via WordPress Application Passwords. Stored in the macOS Keychain. Revoke from your WP admin any time.
Standard YAML frontmatter. Your content stays yours on your disk. Cancel any time and keep every file.
How it works on WordPress
Step
In WordPress admin: Users → Profile → Application Passwords. Name it "Specter" and copy the password — you’ll only see it once.
Step
Open Specter, add a WordPress site, paste your site URL, username, and the Application Password. Specter tests the connection before continuing.
Step
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.
