The fastest way to feed your codebase to AI — and the easiest way to understand what you’re feeding it.

If you’ve ever copy-pasted a plugin folder into ChatGPT, Claude, Cursor, or Copilot, you already know the problem. AI tools are only as good as the context you give them. They can’t fix what they can’t see. And manually opening files, copying paths, and pasting them one by one — for every prompt, on every project — is the silent tax on AI-assisted development.

Structure Viewer is the missing first step. Browse any plugin or theme on your WordPress site, see its complete file tree at a glance, and export the entire structure as a single clean tree — TXT, JSON, XML, or one-click clipboard copy — that drops directly into any AI prompt as ready-to-use context. No FTP, no cPanel, no zipping folders, no guesswork.

Whether you’re prompting an AI to refactor a plugin, audit third-party code, generate tests, write documentation, or trace a bug through someone else’s theme — the conversation goes better when the AI knows the whole map up front.

🤖 Built for AI-Assisted Development

Modern coding workflows look different than they did two years ago. You’re working alongside an AI, and your AI works better when it has structural context. Structure Viewer is designed for exactly that workflow:

Tree-format exports purpose-built for LLM context windows — clean ASCII, no markdown noise, token-efficient
One-click clipboard copy — emoji tree format that pastes into any AI chat with perfect alignment
Filter before you export — exclude node_modules, vendor, build artifacts, or anything you don’t want bloating your context
Read source inline — open any file in the browser modal, copy the snippet you need, paste into your AI conversation
Pro: Comparator — diff two versions of a plugin and feed only the changed lines to your AI for targeted code review
Pro: FlatPack — extract just the PHP, just the JS, or just the CSS from any plugin and hand the AI a focused codebase
WP-CLI exports — script structure dumps directly into your AI agent’s working directory

Stop pasting one file at a time. Give the AI the whole map first, then ask better questions.

Interactive tree view — expandable folders with icons for every file type (PHP, JS, CSS, images, JSON, XML, and more)
Searchable item picker — switch between All Plugins, individual plugins, All Themes, and individual themes instantly
Live tree search — type to filter files in real time, jump between matches with next/prev navigation
File type tag strip — one click to show only PHP files, only CSS, only images — whatever you need

🚀 Structure Viewer Pro

Unlock two powerful Pro tools for developers who need to go deeper.

🔀 Comparator — Know Exactly What Changed

Ever updated a plugin and wondered what actually changed? Comparator shows you a precise, color-coded, line-by-line diff between any two versions — so you can audit updates, review customizations, and catch unwanted changes before they cause problems.

Compare two plugin ZIPs side by side
Compare an installed plugin or theme against any uploaded ZIP
Compare two individual files for a targeted spot-check
Added lines in green, removed in red, changed lines clearly highlighted
Works on large plugins and minified CSS/JS files — auto-tokenizes before diffing
Expand/collapse per-file diff blocks to focus on what matters

📦 FlatPack — Extract Only What You Need

Need just the CSS from a plugin? Or all the PHP files for a code review? FlatPack extracts any plugin or theme ZIP and flattens it into a single, clean download — no nested folders, no hunting through directory trees.

Upload any plugin or theme ZIP and see all its files in a live preview instantly
Filter by PHP, CSS and JS, images, or any custom extension — preview updates live
Only the filtered files are included in the output ZIP
Smart collision-safe naming: duplicate basenames get a folder prefix automatically
Download a single flat ZIP in seconds
