• Xcode 16+
• ~100–500 MB storage for speech models

Architecture

Dictus is organized into three Xcode targets:

Target	Role
DictusApp	Main app — onboarding, settings, model manager
DictusKeyboard	Keyboard extension — custom keyboard + dictation trigger
DictusCore	Shared framework — App Group storage, models, preferences

The app and the keyboard extension communicate through an App Group (group.solutions.pivi.dictus). WhisperKit runs inside DictusApp (the keyboard extension has a ~50 MB memory limit), and an audio bridge handles cold start so dictation works seamlessly from the keyboard.

Contributing

Contributions are welcome — see CONTRIBUTING.md. Good entry points:

• good first issue and help wanted in Issues

• Translations & locale tuning (FR is the reference; EN / DE in progress)

Privacy

Dictus collects no user data. All speech processing happens on your device. See our Privacy Policy.
