Nexus Helper

About

Nexus Helper is a developer-focused Chrome extension that captures rich, structured context from any web page and formats it for AI-assisted code editors like Cursor, Antigravity, VS Code, Windsurf, and Zed.

A floating, draggable widget lives on every page and generates XML-tagged context optimized for AI models -- including routes, framework detection, component trees, error traces, API response shapes, viewport info, performance hints, and more.

KEY FEATURES:

Floating Widget
Draggable, resizable widget with 3 states (collapsed capsule, expanded, maximized). Sleek glassmorphic minimized state with a breathing health dot. Hover to expand quick-action buttons. Keyboard toggle with Alt+N.

AI Context Engine
Generates structured context across 15 sections: task prompt, framework info (Next.js, Nuxt, Vite auto-detected), page location, route params, related source files, layout chain, component tree, UI state, structured errors, data fetching, API response shapes, accessibility tree, viewport info, performance hints, and DOM snapshot.

Context Presets & Auto-Detection
One-click presets: Auto, Bug Fix, UI, Full, Minimal. As you type, Nexus Helper auto-detects your intent (bug fix, styling, performance, API, accessibility, routing, form) and highlights the matching preset. A floating intent badge gives real-time feedback.

API Docs Integration
Sign in with Firebase (email/password or Google) and access your published API documentation from NexusDocer directly inside the extension. Search and attach endpoints, folders, or entire collections to your AI context. Smart auto-suggest finds matching API endpoints as you type keywords like "implement" or "integrate".

Default Editor & Auto-Copy
Choose your default editor (Cursor, Antigravity, VS Code, Windsurf, Zed). When you click "Open Editor", context is auto-copied to your clipboard, ready to paste.

Token Counter
Real-time estimated token count with color-coded warnings (green/yellow/red) to help you stay within model limits.

Quick Capture
Copy route, copy screenshot, copy context, open editor -- all in one click from the minimized action bar.

Debug Panel
Real-time error and network monitoring with search and filtering.

Project Indexing
Auto-detects project path from React fiber, indexes files, and resolves routes to source files.

Additional
Clipboard history, recent routes, speech-to-text input, autocomplete for routes (/) and files (@), ghost text suggestions, export/import settings.
