WorDrop - Offline Personal Safety & Automation

WorDrop is an offline, privacy-first Android application designed for personal safety, privacy, and automation. It continuously listens for custom "trigger words" (hotwords) and executes a configurable set of actions when detected.

Key Features

• Offline Speech Recognition: Powered by Vosk, identifying trigger words without internet access.
• Privacy First: All audio processing happens locally on the device. No audio is ever sent to the cloud.
• Custom Trigger Categories: Group multiple aliases (e.g., "Hey Assistant", "Computer") under a single category.
• Configurable Actions:
  • Media Control: Pause music/audio.
  • Haptic Feedback: Custom vibration patterns.
  • Visual Alert: Flash the torch/flashlight.
  • Privacy: Mute all audio, clear clipboard.
  • Safety: Loud siren (panic mode).
  • Automation: Launch apps.
• Sensitivity Control: Choose between "Fast" (instant response) and "Strict" (high accuracy) modes.
• Modern UI: Beautiful Material 3 design with full Dark Mode support and a clean Grid Dashboard.

Installation

1. Clone the repository:

   git clone https://github.com/Ayush12358/wordrop.git

2. Install dependencies:

   flutter pub get

3. Run on an Android device:

   flutter run

Usage

1. Download Model: On first launch, download the offline language model (approx. 50MB).
2. Add Triggers: Go to the "Trigger Categories" screen and add a new category (e.g., "Panic").
3. Configure Actions: * App Launch: Search for installed apps (e.g., "Spotify") to launch specific apps. * Safety: Select "Play Siren" or "Fake Call" for emergency scenarios.
4. Sensitivity Control: * Global: Set default sensitivity in Settings. * Per-Trigger: In Settings, enable "Per-Trigger Sensitivity", then customize each trigger (Fast/Strict) in the Edit dialog.
5. Start Service: Tap the central microphone button on the Home screen to start the background listening service.

Permissions

WorDrop requires the following permissions to function:

• Microphone: To listen for trigger words.
• Notification: To show the persistent background service notification.
• Flashlight: For visual alerts.
• Vibration: For haptic feedback.
• Overlay (System Alert Window): For certain background interactions.
