NearMitra – Open Source Android & Windows File Sharing, Local AI and Device Connectivity

NearMitra – Open Source Android & Windows Connectivity App

NearMitra is a free, open-source cross-platform connectivity application designed to connect Android smartphones and Windows PCs through local networking and supported peer-to-peer connections.

Built using Flutter, Kotlin, Go and web technologies, NearMitra combines wireless file sharing, device discovery, local messaging, Nearby AI, voice and video communication, and audio streaming in one connected workspace.

Unlike traditional file-sharing tools, NearMitra also allows an approved Android phone to interact with a locally hosted AI model running on a Windows PC, including models served through Ollama.

KEY FEATURES

1. Android & Windows File Sharing

Transfer files and folders wirelessly between supported Android and Windows devices over local network connections.

2. Nearby Device Discovery

Discover compatible devices through LAN, Wi-Fi Direct and supported peer-to-peer connectivity mechanisms.

3. Local Chat & Messaging

Exchange messages and supported attachments between connected devices.

4. Nearby AI with Ollama

Access a configured Ollama model running on a Windows computer directly from an approved Android device.

5. Voice & Video Communication

Make supported voice and video calls between connected devices, with permission-controlled media access.

6. Camera & Screen Sharing

Share supported camera streams or screen content after granting the required permissions.

7. Windows-to-Android Audio Streaming

Stream supported PC audio to an Android device using NearMitra's Wi-Fi Audio functionality.

8. Local-First Connectivity

Use supported nearby communication features without depending on cloud storage or a public internet connection.

9. Optional WAN Communication

NearMitra documents optional remote connectivity using separately configured Firebase Realtime Database and WebRTC infrastructure.

10. Open-Source Architecture

Explore and extend a GPL-3.0-only licensed project involving Flutter, Android native integration and Windows desktop services.

INSTALLATION & SETUP

1. Visit the official NearMitra website.
2. Open the Downloads section.
3. Download the published Android APK and Windows x64 installer.
4. Install the application on both devices.
5. Connect the devices through a supported local network.
6. Discover the nearby device and approve the connection.
7. Start using supported messaging and file-sharing functionality.

For Nearby AI, install and configure Ollama separately on the Windows PC, select a supported model and explicitly enable AI sharing for the approved Android device.

SYSTEM REQUIREMENTS

Compatible Android smartphone
Windows x64 computer for the published Windows build
Supported local network or peer-to-peer connectivity
Required device permissions for selected features
Ollama installed and configured for local AI functionality
Firebase/WebRTC configuration for optional WAN features

PRIVACY & SECURITY

NearMitra supports permission-controlled connections and local communication. However, not all local transport paths provide end-to-end encryption. Users should prefer trusted networks and review permissions before sharing sensitive information.

FUTURE ROADMAP

The NearMitra project outlines potential AI agent and Model Context Protocol (MCP) integration. These planned capabilities could expand the application into permission-controlled AI-assisted device workflows. However, AI agents and MCP integrations are not currently available features.

WHO SHOULD USE NEARMITRA?

NearMitra is suitable for Flutter developers, Android and Windows users, students, open-source contributors, local AI enthusiasts and anyone exploring wireless cross-device connectivity.

It is particularly useful for people who want to transfer files without USB cables, access desktop-hosted Ollama models from Android, communicate across devices and experiment with open-source networking technologies.
