PinMe - Intelligent Screen Capture & Extraction

Project Overview

PinMe (supreme) is an Android application designed to intelligently capture screen content and extract key information (e.g., pickup codes, train tickets, verification codes) using Vision Large Language Models (LLMs). The extracted information is then presented via Meizu Flyme's Live Notifications (Capsule) or a standard Android AppWidget for quick access.

Technology Stack

• Language: Kotlin
• UI Framework: Jetpack Compose (Material3)
• Architecture: Modern Android Architecture (Compose + Room + Coroutines)
• Database: Room (SQLite abstraction)
• Networking: OkHttp (for LLM API communication)
• AI/LLM Integration: OpenAI-compatible API client (supports Zhipu AI, SiliconFlow, Custom)
• Key Android APIs:
  • MediaProjection: For screen capture.
  • AccessibilityService: For silent/background capture.
  • Glance: For building AppWidgets with Compose-like syntax.
  • NotificationManager: For system and Flyme-specific notifications.
