Structure Viewer is a WordPress file explorer and AI context builder for developers — browse, inspect, view source code, and export the complete file structure of any installed plugin or theme, directly from your WordPress admin dashboard. No FTP, no cPanel, no server access needed. Open any file, read its source code with syntax highlighting, search across your entire codebase, and export the full file tree as TXT, JSON, XML, PDF, or clipboard copy — all without leaving WordPress. And if you work with any AI coding tool — ChatGPT, Claude, Cursor, Copilot, Gemini, or anything else — Structure Viewer is the missing first step. Export your plugin’s complete structure as ready-to-use AI context in one click, and give your AI the full codebase map before you ask it anything. — 🤖 Built for AI-Assisted Development Modern coding workflows look different than they did two years ago.
