I’m excited to share the beta release of Amender, a new WordPress plugin designed to make editing content as flexible as styling pages with Microthemer.
What is Amender?
Amender is a new kind of content editor for WordPress. It works directly on the final page output, so it doesn’t matter where your content came from: theme templates, plugins, page builders, Gutenberg blocks, shortcodes, or even custom PHP.
If it renders on the page, you can edit it.
Amender fills a gap that no other WordPress tool currently does.
You can make changes visually by clicking and editing text or elements, or you can ask the built-in AI assistant to do the work for you. Prefer speaking to typing? Just hit the microphone icon and dictate your request.
Want to tweak a heading inside a third-party form? Remove an unwanted section added by a plugin? Add your own styles or scripts without touching theme files? Amender lets you do all of that visually, with AI, or by writing HTML, CSS, or JS directly.
But just to be clear: Amender is not a page builder.
It’s not trying to replace tools like Elementor or Bricks. It doesn’t offer drag-and-drop widgets for building full page layouts from scratch. Instead, Amender is designed to help you edit, refine, and extend the content you already have.
You can:
Add, remove, or adjust sections on any page
Format content with the built-in rich text editor
Use the AI assistant to insert more complex components (like sliders, tabs, or accordions)
Fine-tune the output of themes and plugins that don’t give you full control
In short, Amender augments your current WordPress stack, it doesn’t compete with it.
Of course, developers can use Amender to replace entire pages if needed, but the visual controls are geared toward editing snippets of content here and there.
Who’s Amender For?
Non-technical users
If you’re not comfortable with code, no worries. You can:
Click to edit text and images directly on the page
Use the AI assistant to make changes by describing them in plain English
Dictate your requests if you prefer talking to typing
Make ambitious changes you never thought possible by yourself
Developers
If you are comfortable with code, Amender gives you a ton of power (and if you’re not, the AI assistant can do everything below):
Edit any WordPress content regardless of how it was created
Switch between AI + visual editing seamlessly
Edit HTML, CSS, JS without touching theme/plugin code
Run lightweight custom JS functions without boilerplate
Event-based interactivity: make things happen on hover, scroll, click, etc.
Lazy load any asset and remove unused code for better performance
Speed up your site: lazyLoad content, clean out unused code
Built-in support for popular JS tools: GSAP, Alpine.js, and THREE.js
Tailwind-friendly: live visual Tailwind updates if you prefer utility-first styling
NPM in WordPress: import and manage JS libraries easily, no bundling needed
Transparent changes: all edits are logged, undoable, and only go live when you hit “publish”
Performance metrics: server-side processing time and page weight is calculated
Amender is like a universal child theme for any kind of WordPress output.
Why I Built Amender
When a theme or plugin doesn’t quite do what you need, or what your client expects, you’re often stuck with an uncomfortable decision:
Start over with a different tool or a fully custom solution
Modify the source code, but sacrifice future updates
Accept the limitation and explain why it can’t be changed
None of these are ideal. I built Amender to offer another option. A clean, upgrade-safe way to make precise changes to any WordPress page, without having to ditch a tool that saves you a ton of time getting you 90% there.
Another motivation was the rise of AI. The top AI models are getting impressively good at writing code. But there’s a missing link. How does that code actually make it onto your site? How do you go from “here’s the code” to “this is now live”?
Amender provides that connection. It gives the AI a way to apply changes directly to your site, safely and in context, with full control and undo support.
Common Questions and Concerns
Will this slow down my site?
Performance was a key priority from the start. Server-side HTML edits typically take under a millisecond to process. For every site, Amender shows the actual time taken. On the front end, Amender’s core JavaScript is just 16KB. It also reports the size of any user-added JS or CSS, including packages imported via the built-in npm manager, so you stay in full control of what gets loaded.
Is this a security risk?
All content editing plugins introduce some degree of risk, as seen in the many vulnerability reports published by Wordfence for page builders, form plugins, and e-commerce tools. But there are a couple of reasons why there have never been any known exploits of Microthemer in its 10+ year lifespan, which also apply to Amender.
Microthemer and Amender are both limited to administrator roles. No other role (e.g. contributor) can access the interface or save changes. I have resisted requests to support varying user roles for this added security benefit.
In production, you can copy some code to your theme’s functions.php file, or use a mini plugin (now called “Microloader”) to apply the changes without having the editor installed. Microloader just loads assets made with the editor, and so drastically reduces the surface area for malicious attacks.
Will it break anything?
Amender doesn’t overwrite your original files or database content. All changes are added as a layer on top, and are fully reversible. You can preview changes, undo individual edits, and return your site to its exact original state at any time. Nothing is permanent. Even published changes can be rolled back any time.
Will clients have access to this?
Amender is a powerful plugin. If you’re working on a client site, you probably don’t want them accidentally undoing your work.
As mentioned, only administrators can access Amender. Other roles (like editors or contributors) won’t see the interface at all. If your client does have admin access, the safest option is to install Microloader on the live site. This applies your changes without keeping the editor active.
You can temporarily reinstall Amender whenever you need to make further edits, then remove it again once you’re done.
How do I know what changes Amender has made?
Amender logs every change made to each page. The review panel shows exactly what’s been added, removed, or modified, with quick links for editing or deleting any change.
What about AI accuracy?
The built-in AI assistant is capable of impressive changes. I’ve spent a lot of time testing and improving the assistant, and will continue to do so. But like all AI tools, it isn’t perfect.
For simple text and style changes, you can expect it to work almost all of the time.
With animations, it should produce a working effect the majority of the time. Further prompts may be needed to e.g. set the desired speed and scale of movement.
Complex layout adjustments are still a bit hit and miss. I’ve made progress by giving the model the ability to analyse the page like a developer, but more work is needed to ensure it uses these abilities consistently.
The good news is that Amender lets you preview and refine the AI’s output before publishing anything. And the “Retry” option (undo -> resubmit prompt) can really lighten your load when you’re pushing the boundaries of what it can do.
Do I need to know how to code?
No. You can use the visual editor or ask the AI assistant to make changes for you. But if you are comfortable with code, Amender gives you full access to HTML, CSS, and JS.
Try It Free: Pay When You Publish
Amender is built to be explored without pressure. You can test all of its features freely. Make changes, experiment, undo, preview, and only pay once it’s completed the job successfully.
If you delete your changes or deactivate the plugin, your site goes back to exactly how it was. Nothing is overwritten. Nothing is lost.
This is a new kind of system, and it’s completely fair to be sceptical. Can it really edit anything? Will the AI assistant understand what I mean? The best way to find out is to try it. And if it doesn’t work for your use case, you’ve lost nothing.
It’s worth pointing out that I don’t get paid unless Amender solves your problem. This reflects the confidence I have in what it can do. And once you’ve discovered this for yourself, permanently low price plans should make buying a license a no-brainer.
I’d Love Your Feedback
This is an early release, and you’re among the first to hear about it. If you give Amender a spin, I’d love to hear your thoughts, good or bad. What works well? What feels rough? What’s missing?
