Takt is a SwiftUI-based iOS app that automatically extracts event information from images and creates calendar events. The app uses iOS's built-in Vision framework for text recognition and provides a comprehensive calendar management system.
- Share from Anywhere: Share photos directly from Photos app, Safari, or any app
- Quick Capture: Snap a poster/flyer → Share to Takt → Auto-extract event
- Background Processing: Events extracted automatically when shared
- No App Switching: Process images without leaving your current app
Example Use Cases:
- Concert poster on street → Photo → Share to Takt → Event added
- Email screenshot → Share to Takt → Meeting extracted
- Restaurant flyer → Share to Takt → Deadline saved
- Voice dictation on-the-go when you can't type
- Multiple Input Sources: Import images from photo library, camera, or paste from clipboard
- OCR Text Recognition: Uses Vision framework for accurate text extraction

- Stage 2 - Natural Language (NSDataDetector): Natural dates ("Wed 31 Aug"), context-aware deadline detection
- Stage 3 - Apple Intelligence (Future): Semantic understanding, category detection (Concerts, Meetings)
- Deadline Detection: Automatically identifies and sets deadlines
- Event Naming: Intelligently extracts event names from text content
- Offline-First: All processing happens on-device, no backend required
