Everything you need for AI-assisted debugging
Nexus Helper captures every detail AI needs to understand your app — from framework versions to API documentation, all in one click.
Floating Widget
Draggable, resizable widget with 3 states. Collapses to a breathing dot, expands on hover, remembers your position.
AI Context Engine
Generates 16 structured context sections — framework info, routes, errors, network, UI state, API reference, performance, and more.
API Docs Integration
Attach API endpoints, folders, or collections from NexusDocer. Full request/response details included in AI context.
Smart API Auto-Suggest
Type "implement login" or "integrate payment" and matching API endpoints appear automatically as suggestions.
Firebase Authentication
Sign in with email/password or Google to access your API docs. Secure token management with auto-refresh.
Intent Auto-Detection
Analyzes your prompt keywords and automatically selects the right context preset. Bug fixes, UI tasks, API implementation — all covered.
XML-Formatted Output
Context is formatted in clean XML tags that AI models parse perfectly. Task, framework, errors, UI state — all structured.
Error & Network Capture
Automatically captures console errors with stack traces and network requests with timing, status, and response shapes.
