๐Ÿ’Ž Elysia's Code Companion v1.2.2

Your AI Dev Partner - Chat, Analyze, Build Together

Version License Built

"Code companion in your browser - AI-powered code analysis" ๐Ÿ’œ "Built by Elysia Suite โ€” Because coding is better together"

๐Ÿ’™ What is Elysia's Code Companion?

Elysia's Code Companion is a standalone web app that brings the power of AI code analysis to your browser. Open any folder, chat with the AI, get insights, find bugs, and improve your code - all without leaving your browser.

๐ŸŽฏ Why This App?

Problem: You can't always be in VS Code, but you still want AI help with your code.

Solution: A browser-based code companion that:

  • โœ… Reads local folders (File System Access API)
  • โœ… Analyzes code structure
  • โœ… Chats with you about your code
  • โœ… Finds bugs & suggests improvements
  • โœ… Works offline (after initial load)
  • โœ… No backend needed (100% client-side!)

โœจ Key Features

๐Ÿ“‚ File System Access

  • Open any folder on your computer (Windows 11 Edge/Chrome supported!)
  • Browse files in elegant tree view
  • Preview code with syntax highlighting
  • Search files instantly

๐Ÿ’ฌ AI Chat Interface

  • Stream responses in real-time (like VS Code!)
  • Natural language queries about your code
  • Context-aware (AI "sees" your files)
  • Markdown rendering + code syntax highlighting

๐Ÿง  Smart Analysis

  • /scan - Full project analysis
  • /analyze [file] - Deep dive into specific files
  • /tree - Project structure visualization
  • /stats - Language/file type statistics

๐ŸŽจ Code Viewing & Artifacts

  • Fullscreen Code Viewer - Read code comfortably in large modal
  • โœจ Artifacts Preview - Live HTML preview (like Claude.ai!)
  • Auto-resolve CSS/JS dependencies
  • Syntax highlighting in viewer

Tips & Tricks

๐Ÿ’ก Keyboard Shortcuts:

  • Ctrl + O โ€” Open folder picker
  • Ctrl + K โ€” Focus search box
  • Ctrl + Enter โ€” Send message (when chat input focused)
  • Arrow Up/Down โ€” Navigate file tree (when tree focused)
  • Enter โ€” Open selected file in tree
  • Escape โ€” Close modals

๐Ÿ’ก Smart Tips:

๐Ÿ’ก Mention specific files in your questions - the AI will include them in context automatically

๐Ÿ’ก Use /scan first when opening a new project - gives the AI full context

๐Ÿ’ก Preview files by clicking in the tree - see code with syntax highlighting

๐Ÿ’ก Search files using the search box - fast filter

๐Ÿ’ก ๐Ÿ” Fullscreen Viewer - Click the magnifying glass icon in preview to read code in large modal

๐Ÿ’ก โœจ Artifacts Mode - For HTML files, click the sparkle icon to preview live in browser (like Claude.ai!)

๐ŸŽจ Code Viewer Features

Fullscreen Code Viewer:

  • Large, comfortable reading view
  • Full syntax highlighting
  • Copy entire file with one click
  • Quick switch to Artifact mode (for HTML)

โœจ Artifacts Preview (HTML Live Preview):

Artifacts are live HTML previews - just like Claude.ai! ๐ŸŽจ

Instead of just reading HTML code, you can see it rendered with full interactivity.

How to use:

  1. Open any .html file in the tree
  2. Click โœจ (sparkle icon) in preview panel
  3. Or click ๐Ÿ” (fullscreen) then โœจ

Features:

  • โœ… Renders HTML in sandboxed iframe (safe!)
  • โœ… Auto-loads CSS from <link> tags
  • โœ… Auto-loads JS from <script> tags
  • โœ… Relative paths resolved automatically
  • โœ… Fully interactive (buttons, forms, animations work!)
  • โœ… Refresh with ๐Ÿ”„ button anytime
  • โœ… Switch to code view with ๐Ÿ“ button

Example:

If your index.html has:

<link rel="stylesheet" href="styles.css" />
<script src="app.js"></script>

Elysia automatically finds and inlines both files! No manual setup needed.

Perfect for:

  • ๐ŸŽจ Previewing static websites
  • ๐Ÿ“ฑ Testing responsive designs
  • ๐ŸŽฎ Checking interactive components
  • ๐Ÿ’Œ Viewing email templates
  • ๐Ÿ“Š Data visualizations

Security: Runs in sandbox with allow-scripts allow-same-origin - isolated from main app.

๐ŸŽจ Customization

Change Theme

Edit styles/main.css - all colors defined in :root variables:

  • Grok 4.1 Fast (recommended - fast & smart)
  • Claude Opus 4.5 (thoughtful & detailed)
  • GPT-5.1 (creative & versatile)
  • DeepSeek v3.1 (budget-friendly)

Change Max Files

Settings โ†’ "Max Files to Analyze" (default: 100)

Increase for large projects, decrease for performance.

๐Ÿ› Troubleshooting

"File System Access API not supported"

Solution: Use Chrome or Edge browser (not Firefox/Safari)

"Failed to open folder"

Solution:

  1. Make sure you're using a compatible browser
  2. Grant permission when browser asks

"API error: 401"

Solution: Check your OpenRouter API key in Settings

Chat not streaming

Solution:

  1. Check internet connection
  2. Verify API key is valid
  3. Try different model

Files not showing

Solution:

  1. Make sure folder has text files (.js, .py, .md, etc.)
  2. Binary files are skipped automatically
  3. Check "Max Files" setting

๐Ÿš€ Future Improvements (v2.0 Ideas)

  • Multi-folder support (open multiple projects)
  • Diff viewer (before/after code changes)
  • AI code generation + inline editing
  • Export analysis reports (PDF/Markdown)
  • GitHub integration (clone repos directly)
  • Architecture diagram auto-generation
  • Performance profiling
  • Security vulnerability scanning
  • Dark/Light theme toggle
  • Mobile support (responsive++)
