# UX Plan: Desktop-Only Transcription Listing & Details Interface

## Overview
This document outlines the UX design for a desktop-only web application that allows users to view and manage their video transcriptions and multiple AI-generated summaries.

## Proposed Solution: Integrated Single-Screen Layout

### 1. Three-Column Master Layout

```
[Sidebar List 25%] | [Main Content 50%] | [Details Panel 25%]
```

#### Left Sidebar - Transcription List
- **Vertical scrolling list** of all transcriptions
- **Each list item displays:**
  - Video thumbnail & title
  - Channel name
  - Duration
  - **Summary count badge** (e.g., "3 summaries")
  - Processing status icons
  - Last activity timestamp
- **Top controls:**
  - Search bar
  - Filter dropdown (by date, status, summary count)
  - Sort options

#### Center - Selected Video Details
- **Video Header Section:**
  - Title, channel, date, duration
  - Video thumbnail or mini player
  
- **Summary Selector Tabs:**
  - Horizontal tabs for each summary
  - Tab information:
    - Generation timestamp
    - AI model used (DeepSeek, GPT, Claude)
    - Summary type (Standard/Educational/Executive)
  - "+ New Summary" tab for generating additional summaries
  
- **Active Summary Content:**
  - Full summary text with sections
  - Key points highlighted
  - Confidence scores displayed
  - Word count and reading time
  
- **Actions Bar:**
  - Export (PDF, Markdown, Word)
  - Share
  - Regenerate
  - Delete

#### Right Panel - Interactive Transcript
- **Synchronized Transcript Viewer:**
  - Timestamped segments
  - Click any timestamp to copy shareable link
  - Search within transcript
  - Auto-highlight if video is playing
  
- **Video Preview** (optional mini player at top)
  
- **Metadata Section:**
  - Processing times
  - Token counts
  - Model parameters used
  - Cost estimation

### 2. Key Interactions

#### Summary Management
- **Tab Navigation:**
  - Click tab to switch between summaries instantly
  - Hover tab for tooltip with full metadata
  - Right-click tab for context menu (delete, rename, set as default)
  - Drag tabs to reorder preference

#### Comparison Mode
- **Activation:** Shift+Click two summary tabs
- **Display:** Center panel splits vertically
- **Features:**
  - Side-by-side summary display
  - Synchronized scrolling
  - Difference highlighting
  - Merge capabilities
- **Exit:** ESC key or click single tab

#### Keyboard Shortcuts
- `↑/↓` - Navigate transcription list
- `1-9` - Quick switch between first 9 summaries
- `N` - Generate new summary
- `E` - Export current summary
- `C` - Toggle comparison mode
- `/` - Focus search
- `Space` - Play/pause video (if player active)
- `T` - Toggle transcript panel

### 3. Visual Design Decisions

#### No Modals Approach
- All interactions happen in-place within the three columns
- Settings/options appear as slide-down panels within their column
- Confirmations use inline alerts, not modal dialogs
- Forms expand inline rather than opening new windows

#### Information Density
- **Compact list items:** 60px height to show more transcriptions
- **Thin summary tabs:** 32px height to accommodate many summaries
- **Collapsible sections:** In right panel for space efficiency
- **Adjustable column widths:** Drag to resize panels

#### Visual Hierarchy
- **Active states:**
  - Active transcription: Left border accent color
  - Active summary tab: Colored background
- **Status indicators:**
  - Processing: Animated spinner
  - Complete: Green checkmark
  - Error: Red exclamation
- **Typography:**
  - High contrast for important actions
  - Muted colors for inactive elements

### 4. Enhanced Features

#### Smart Summary Display
- **Auto-detection:** Identify summary type from content
- **Color coding:**
  - Blue = Standard summary
  - Green = Educational summary
  - Purple = Executive summary
  - Orange = Custom summary
- **Quality indicators:**
  - Star rating (1-5)
  - Confidence percentage
  - "Best" badge for highest-rated
- **Version tracking:** Show edit history

#### Bulk Operations
- **Multi-select mode:**
  - Checkbox appears on hover
  - Select all/none controls
  - Selection count display
- **Bulk actions:**
  - Delete multiple
  - Export as batch
  - Re-process selected
  - Archive old transcriptions

#### Advanced Filtering
- **Filter options:**
  - Has transcript
  - Has summary
  - Multiple summaries (2+, 3+, etc.)
  - Date range picker
  - Specific AI model
  - Summary type
- **Saved filters:**
  - Save current filter as preset
  - Quick filter buttons: "Today", "This Week", "Needs Summary"

### 5. Component Structure

```typescript
// Main layout component structure
<div className="flex h-screen">
  {/* Sidebar List */}
  <TranscriptionSidebar 
    transcriptions={transcriptions}
    selectedId={selectedId}
    onSelect={setSelectedId}
    filters={filters}
    onFilterChange={setFilters}
    className="w-1/4 border-r"
  />
  
  {/* Main Content */}
  <SummaryViewer
    transcription={selectedTranscription}
    summaries={summaries}
    activeSummary={activeSummary}
    onSummaryChange={setActiveSummary}
    comparisonMode={comparisonMode}
    onComparisonToggle={toggleComparison}
    className="w-1/2"
  />
  
  {/* Details Panel */}
  <TranscriptPanel
    transcript={transcript}
    metadata={metadata}
    videoUrl={videoUrl}
    showVideoPlayer={showVideoPlayer}
    className="w-1/4 border-l"
  />
</div>
```

### 6. State Management

```typescript
interface TranscriptionState {
  // List state
  transcriptions: Transcription[]
  selectedId: string | null
  filters: FilterOptions
  sortBy: SortOption
  
  // Summary state
  summaries: Summary[]
  activeSummaryId: string | null
  comparisonIds: string[]
  
  // UI state
  sidebarWidth: number
  detailsPanelWidth: number
  showVideoPlayer: boolean
  transcriptSearchQuery: string
}
```

- [ ] Smooth animations and transitions
- [ ] Error states and empty states
- [ ] User preferences persistence
- [ ] Accessibility audit (WCAG 2.1 AA)

### 8. Technical Considerations

#### Performance
- **Virtual scrolling** for transcription list (react-window)
- **Lazy loading** for summary content
- **Debounced search** (300ms delay)
- **Memoization** for expensive renders

#### Data Management
- **Local caching** of frequently accessed summaries
- **Optimistic updates** for better UX
- **Background sync** for new transcriptions

- **Current API:** Extend to support multiple summaries
- **Chat System:** Link to chat view from transcription
- **WebSocket:** Real-time updates for processing status

### 9. Success Metrics

- **Load time:** < 2 seconds for initial view
- **Interaction delay:** < 100ms for tab switches
- **Summary generation:** Clear progress indication
- **User efficiency:** < 3 clicks to any summary
- **Discoverability:** All features accessible via UI or keyboard

### 10. Future Enhancements

- **AI-powered search:** Natural language queries across all content
- **Summary templates:** User-defined summary formats

- **Analytics dashboard:** Usage patterns and insights
- **API access:** Programmatic access to summaries

## Conclusion

This desktop-focused design maximizes screen real estate while eliminating modal interactions. The three-column layout provides efficient access to all transcriptions and summaries while maintaining context. The no-modal approach ensures all interactions happen in-place, creating a smooth and uninterrupted workflow for power users.
