How to edit WordPress posts with Claude (and other AI)

AI is very good at rewriting prose, fixing copy, tightening intros, and grinding through the kind of edits nobody enjoys doing by hand. The problem is a chat window only ever sees the one post you paste into it. There’s no plugin that drops a model into the Block Editor, and wp-admin is a hosted panel behind a login. So you end up pasting posts in and out one at a time, with no view of the rest of the site and no diff before it ships.

So the fix is the obvious one: put your whole archive somewhere the AI can read it all at once. Connect WordPress to Spectersync in the browser and your posts open as clean, editable content. Run an AI recipe across the whole site, review what it changed as a diff, and publish back — including edits to posts you’ve already published, not only new drafts.

This is the hands-on version. If you want the bigger-picture case for AI plus WordPress, read the overview first.

A note before we start: Spectersync isn’t an AI itself. It’s the workflow and control layer that runs the model over your whole site and shows you every change before it ships. Browsing your content and reviewing diffs are free; only AI runs spend credits, and every workspace opens with 500 free.

The workflow, step by step

Connect your site. Follow the connect guide — you’ll create an Application Password in wp-admin and paste it into the Spectersync workspace. Nothing to install. Subscribe now for 500 free credits when your workspace opens.
Your archive lands in the workspace. Every post and page is clean, editable content with its title, slug, status, categories, tags, featured-image URL, and your Yoast or Rank Math meta title and description preserved.
Pick a recipe — or edit by hand. A two-word fix is free; you just edit the post and publish. For anything across the archive, run an AI recipe with your whole site as context.
Give it a specific instruction. Be clear about scope — one post or the whole archive — and about what you do and don’t want touched. Vague prompts produce vague edits.
Read the diff. This is the step that keeps your voice intact. Throw out anything that sounds like a robot, keep the lines that earn their place.
Review the dry-run diff. Before anything reaches WordPress, Spectersync shows you exactly which posts would be created, updated, or flagged as a conflict. After a big AI run this is the safety net you’ll be grateful for.
Publish back. If the diff looks right, push the edits to WordPress over the REST API. If there’s a conflict — you changed a post in wp-admin and the recipe changed it — Spectersync asks you which version wins instead of silently clobbering one. Every publish keeps a snapshot behind it.

Recipes that earn their keep

These are the kinds of jobs that are an afternoon by hand and minutes across the whole archive.

Rewrite the intro paragraph of every post to lead with the reader's
problem instead of a generic hook. Keep the same facts, keep my
voice, and don't touch anything below the first heading.

For any post whose meta description is empty, write a ~155-character
description based on the post body. Leave posts that already have
one alone.

In this single post, fix passive voice and cut filler words. Show
me the changes — don't rewrite sentences that are already clear.

Start narrow. Run a recipe on one post, check the result, then scale it to the archive once you trust the output. Don’t hand an untested recipe to five hundred posts and hit go.

You review the diff — that’s the whole point

The reason this workflow beats an auto-publishing AI plugin is the human in the loop. Nothing reaches your live site until you’ve looked at it. You read the diff in the workspace, you keep the lines you like, you send back the ones that sound generic, and only then do you publish. You’re never one click away from pushing AI slop to readers or to Google.

That matters most for posts that already rank or already get traffic. Most “AI for WordPress” plugins are publish-only — they generate new drafts and can’t safely touch what’s live. Because Spectersync is two-way, you can run a recipe over your three-year-old cornerstone post, improve it, review the change, and update it in place without breaking the URL, the canonical, or the meta you’ve already invested in.

Where this fits

Editing one post for clarity is the everyday case. The same setup scales straight into bigger jobs — for example, bulk-editing WordPress posts for SEO, where one recipe generates or rewrites meta descriptions, titles, and internal links across the whole archive at once, then you review and publish.

The mental model is worth holding onto: WordPress stays your publishing home, your Spectersync workspace is where the AI does the actual writing work, and you review every change before it ships. Spectersync just keeps the two ends honest so the edit you read in the diff is exactly the edit that lands on the site.

Prefer the desktop edition?

If you’d rather run the engine locally — your archive as plain .md files on your Mac, edited with Claude Code, your own scripts, or any tool, with nothing routed through our servers — that’s the desktop and open-source edition. The hosted webapp is the fastest way in. Subscribe now →
