Modern Matrix messenger based on FluffyChat codebase.

QuikxChat is a fork of FluffyChat with redesigned UI and additional features. Built with Flutter, it provides secure messaging through the Matrix protocol with end-to-end encryption.

Beta - Active development, expect bugs and breaking changes.

• Security: End-to-end encryption (E2EE) by default

• AI Features: Voice-to-text transcription for voice messages (optional)
• Customization: Custom themes, wallpapers, color schemes, font sizes
• Translation: Built-in message translation (beta)
• Multi-account: Support for multiple Matrix accounts
• Notifications: UnifiedPush integration for privacy-focused notifications
• Cross-platform: Android, Linux, Windows, Web support

• ✅ Android (5.0+)
• ✅ Linux (AppImage, tar.gz)
• ✅ Windows (tested)
• ✅ Web
• ❌ iOS/macOS (removed)

To enable AI-powered voice-to-text transcription:

1. Create a .env file in the project root:

V2T_SECRET_KEY=your_secret_key
V2T_SERVER_URL=https://your-server.com

2. Build with environment variables:

# The build scripts automatically load .env file
./scripts/build_apk_release.sh
./scripts/build_linux_release.sh
./scripts/build_appimage.sh

Or run in development:

./run_linux.sh

# Install dependencies
flutter pub get

# Android (with AI features if .env exists)
./scripts/build_apk_release.sh

# Linux AppImage
./scripts/build_appimage.sh

# Linux tar.gz
./scripts/build_linux_release.sh

# Web
./scripts/build_web.sh

# Run with AI features (loads .env automatically)
./run_linux.sh

# Or run manually
flutter run -d linux
flutter run -d chrome
flutter run -d android

# Run with AI features manually
source .env
flutter run -d linux \
  --dart-define=V2T_SECRET_KEY="$V2T_SECRET_KEY" \
  --dart-define=V2T_SERVER_URL="$V2T_SERVER_URL"
