Dicio is a free and open source voice assistant for Android that answers questions with both speech and on-screen feedback. It processes your requests on-device where possible, so you get assistant features like weather, timers, and calculations without sending everything to a company server.
Developer: DicioTeam (Stypox) · License: GPL-3.0 (open source) · Price: Free
Before you start: if you want a wake word other than the default "Hey Dicio", download a .tflite model from the Open Wake Word releases page or a wake word collection first, then import it in the app under Settings > Input and output methods > Import custom wake word.

Why isn’t Dicio Assistant on Google Play?
Dicio is published by its developers on GitHub and F-Droid, not on Google Play; there is an open GitHub issue discussing a possible Play Store release.
Is Dicio Assistant safe?
Dicio is open source under the GPL-3.0 license, and this page links to the official release built by the DicioTeam developers on GitHub. The app downloads small speech-to-text models (around 50MB) automatically from Vosk when needed, and it can request permissions for things like contacts, notifications, and the flashlight depending on which skills you use. Dicio Assistant comes straight from its developer rather than through Google Play, so it hasn’t gone through Google’s app review. As with any app, check the permissions it asks for and install it if you’re comfortable with them.
How to install
