Dicio is a free, open-source voice assistant designed for Android that prioritizes on-device processing to ensure user privacy. It supports a wide range of tasks, from weather updates and media control to hands-free calling and navigation, without relying on cloud-based data storage.
Key Features of Dicio
- Effectively replaces Google Assistant for basic tasks like reminders, app launches, and voice commands.
- Handles hands-free calls with consistent reliability.
- Limitations include incompatibility with Android Auto and certain functionality gaps (e.g., email/sms composition, note-taking).
Dicio operates entirely on the user’s device, eliminating the risk of third-party data tracking. This makes it a strong contender for users concerned about privacy, especially as Google phases out its Assistant service.
Getting Started with Dicio
The app is available on the Google Play Store. After installation, users must grant microphone permissions and download the required speech-to-text model. Initial setup is straightforward, requiring only basic permissions and model downloads to activate the wake word.

To use Dicio, simply activate it with a wake word (pronounced “diss-eee-oh”) followed by a command. Testing revealed it performs well in areas like weather checks, media control, and navigation, though some features like call logging and app launch reliability vary.
Customization and Limitations
Within Dicio’s settings, users can adjust language preferences, themes, and wake word settings. However, advanced features like custom wake words require command-line setup, which may not be ideal for all Android users. Current drawbacks include the absence of Android Auto integration and incomplete support for certain app interactions.
While Dicio cannot yet send messages or take notes, its active development suggests potential for future enhancements. For now, it serves as a viable local alternative to Google’s cloud-dependent services, particularly for privacy-conscious users.
