AI Block Editor – Gutenberg Block Generator & AI Assistant vs Code Engine – PHP Snippets, AI Functions & Automation for WordPress

AI Block Editor adds a Gutenberg blocks assistant inside the WordPress editor. Describe what you want to add or change, and AI Editor will place, arrange, and update WordPress blocks directly in the editor. Use it for complex block layouts or simple edits. It supports the latest OpenAI models and lets you use your own API key. When your theme uses theme.json, AI Editor can follow your global styles, presets, and design tokens like colors, typography, spacing, and layout so generated blocks match your site’s design system. Major updates released in May 2026: theme.json style matching, selected block editing, and newer AI models with reasoning controls. Features Natural language block creation: Describe your desired content in plain language and the AI will handle the rest. Core Gutenberg blocks: AI Editor can use core Gutenberg blocks to create complete page sections and complex layouts, not just add single blocks one at a time. Selected block editing: Select one or more blocks in Gutenberg and ask AI Editor to update the selected content or layout. Custom block editing: Custom and third-party blocks can be edited after you add and select them. AI Editor uses the markup it can see for the selected block, so review the result because custom blocks may have private fields, dynamic rendering, or plugin-specific rules the AI cannot fully infer. Existing content lookup (WordPress 6.9+): AI Editor can look up existing WordPress posts, pages, and public custom post types for context, then use that text while helping you create or edit content. Theme-aware output: For themes that use theme.json, AI Editor can use your theme’s presets and editor settings to keep generated layouts consistent with your site’s colors, spacing, typography, and other design styles. Abilities API support: On WordPress 6.9+, connect custom WordPress Abilities API features to AI Editor so it can use site-specific data or actions while helping in the editor. Resizable sidebar: Drag the left edge of the AI Editor sidebar to make the chat panel wider. GPT model selection: Choose from the GPT models supported by AI Editor and available to your OpenAI account. Reasoning effort controls: Choose how much reasoning the model should use for faster simple edits or more careful complex layout work. Conversation context controls: Limit how many recent chat messages are sent with each request. Prompt caching: AI Editor keeps repeated system instructions stable so OpenAI prompt caching can reuse shared context when available, helping monitor API usage and reduce repeated input processing. Theme compatibility check: Review whether the active theme is a good fit for AI Editor’s Gutenberg and theme style workflow. BYOK: Use your own OpenAI API key. Language translation: Multilingual support. Prompt Examples “Add this article as a magazine-style layout using blocks: (paste article here).” “Create a layout for an About Us page, including sections for a mission statement, team members, and contact.” “Add 3 columns, each with a pricing plan.” “Create a table comparing the caffeine content of popular drinks.” “Rewrite this testimonial block to sound more concise.” “Update the selected columns for better balance.” Getting The Best Results Quickly add content blocks: Ask AI Editor to add headings, sections, buttons, lists, tables, columns, and other core blocks for your content. Turn full copy into blocks: Paste a full page draft or section copy and let AI Editor structure it into blocks. Use existing site content: Ask AI Editor to work from existing posts, pages, or custom post types when the request needs site context. With lower models or no reasoning, be explicit, such as “use the current page content as context” or “find posts about pricing and add a summary section.” Choose settings for the task: Select an available model and adjust reasoning effort based on the complexity of the requested layout or edit. Select the right amount of content: If the change depends on a parent layout, columns, group spacing, or surrounding section structure, select the whole relevant block or section and say what you want changed. Use narrow selections for simple edits: If you only need a specific text, button, heading, or single block changed, select just that block and give a direct instruction. Settings Navigate to Settings -> AI Editor to configure the plugin. OpenAI API Key: Add your own OpenAI API key. Requests are sent from your WordPress site to OpenAI. GPT Model: Choose the model AI Editor should use. Reasoning Effort: Choose none, low, medium, or high. Lower values are faster for simple edits; higher values can help with larger layouts or more careful restructuring but may take longer and use more tokens. Theme Style Context For AI: A short style note used as design direction. AI Editor can rewrite the active theme description with AI. Raw theme presets are handled separately, so this field should stay short and human-readable. Limit Conversation Context Sent To OpenAI: Turn on/off trimming of older chat messages before sending a new request. Max Messages In Conversation Context: Set how many recent messages are kept when conversation context trimming is enabled. The default is 50. Theme Compatibility For AI Editor: Run a compatibility check for the active theme. It reviews Gutenberg support, block theme signals, editor style support, and available theme presets so you can spot where manual cleanup may be needed. Note: AI Editor is powered by OpenAI’s GPT technology. For more information on the data handling and privacy aspects, please refer to OpenAI’s Privacy Policy and Terms of Service. Connect Custom Abilities On WordPress 6.9+, developers can connect custom abilities registered with the WordPress Abilities API to AI Editor. If your plugin or theme registers a custom ability, add an AI Editor config to the ability meta. Example: 'meta' => array( 'ai_editor' => array( 'action_name' => 'get_product_details', 'description' => 'Use this when the user asks for current product details from WooCommerce.', ), ) AI Editor will only use abilities that explicitly opt in. Keep ability results focused and avoid returning large private datasets or unrelated site data. Requirements PHP 7.0+ is recommended, WordPress 5.8+, with Gutenberg active. An OpenAI API key is required.

Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want: frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers. Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem, and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php and praying. I wanted a place where small bits of code are organized, safe, AI-assisted, and reusable everywhere. Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places: AI Engine: your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer. Workflow Engine: your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code. REST / External tools: give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 Snippets Manager Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets, all in one clean dashboard with tags, search, scope filters, and priorities. 🪄 AI-Assisted Coding Describe what you want in plain English and let AI Engine write the snippet: code, name, arguments, and scope included. Refine existing code or implement it straight from your comments. 🤖 Functions as AI Tools Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk. 🔀 Functions as Workflow Steps Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas. 🌐 External Access (REST) Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs. 🛡️ Safe Mode A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence. ⏰ Scheduling Run a snippet daily at a chosen time via WP-Cron (reports, cleanups, syncs) without touching the server crontab. 🧱 Code Blocks & Shortcodes (Pro) Drop PHP or JS straight into a post or page with a Gutenberg block or the [code-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults. Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard. ✨ The big idea: write once, use everywhere This is what makes Code Engine different. A Function snippet is not just code you call from other code. It’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once: 1. As an AI tool, for chatbots and AI agents With AI Engine active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents (Claude, Claude Code, ChatGPT, OpenClaw) can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill. 2. As a workflow step, for automation With Workflow Engine, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps: an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration. 3. As a REST endpoint, for the outside world Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed. Works beautifully with the Meow Apps family Code Engine is one engine in a connected set, each one useful alone, magical together: AI Engine: chatbots, content generation, and MCP. Turns your functions into AI tools. Workflow Engine: visual automation. Turns your functions into draggable steps. SEO Engine: smart, lightweight AI SEO. Social Engine: schedule and automate social posts. Why Code Engine? Reusable, not throwaway Other snippet plugins give you a place to paste code. Code Engine gives you a place to build capabilities that your AI, your workflows, and your external tools can all use. Native to WordPress Clean, fast, and built the WordPress way. No clunky external dashboards, no bloat. AI-native Write snippets with AI, expose them to AI. The whole loop lives in your wp-admin. Developer friendly REST API, MCP tools, function calling, scheduling, import/export, and plenty of filters to hook into. Cared for Part of the Meow Apps family, with regular updates and a real human behind it. 💕
