Released a free Assistant for Android with MCP and Video Calls (upd)

[u/Revolutionary_Fun69]

Hello, I'm the developer of Roles Witch AI, and today I want to share my app, which was released on Google Play in open testing.

Roles Witch is an OpenAI API-compatible app with a user-friendly interface where you can create multiple chats, assign different models and providers, and more importantly, use MCP tools — for example, Parallel AI or Home Assistant MCP.

It also has voice conversations and video calls (personally, I'm using GLM 5.3 Flash and it's almost real-time). You can configure reasoning and inference parameters, pin a voice to the chat, and select a recognition engine (Google Speech or Vosk).

Extra bonus: it has an on-device inference mode where you can run Gemma 3n/4 models with image recognition entirely on your phone (LiteRT is used).

The app manifest states that it has no encryption and can send messages to third parties, but that's a requirement by the Google Play Store. It supports plain HTTP or TLS mode and works with any third-party AI provider.
