Private Mind

Private Mind represents a new era of AI—powerful, personal, and completely offline. Built around the belief that AI should live entirely on your device, Private Mind opens the door to a new kind of experience: fast, secure, and fully private.

All conversations happen locally, with no data sent to the cloud and no internet connection required. There are no sign-ups, no subscriptions, and no hidden costs—just intelligent, customizable AI available anytime, anywhere.

Key Features

• Fully Private & Secure: All conversations and data stay on your device. Nothing is collected or shared.
• Free & Accessible: Use advanced AI models without subscriptions, accounts, or paywalls.
• Chat With Your Documents: Attach a PDF, TXT, Markdown, HTML or CSV file and ask about it. Retrieval and embeddings run on-device, and every answer links back to the passages it came from.
• Images & Voice: Send a photo to a vision-capable model, or dictate a message with on-device speech input.
• Branch Any Conversation: Fork a chat from any message to explore a different direction without losing the original.
• Customizable AI: Choose from supported models or add your own. Save system prompts as reusable presets and tune behavior per chat.
• Built-in Benchmarks: Test and compare models on performance, memory use, and speed — measured on your own hardware.
• Offline by Design: Once a model is downloaded, every feature works without an internet connection.

Installation

Private Mind is available in App Store and Google Play:

• App Store
• Google Play

Getting Started

You will need Node 20+, Yarn, and the native toolchain for your target — Xcode (iOS 17.0+) or Android Studio.

git clone https://github.com/software-mansion-labs/private-mind.git
cd private-mind
yarn

yarn ios       # build, install and launch on a simulator or device
yarn android

Models are not bundled with the app: they are downloaded from Hugging Face on first use, so the first run needs a network connection. Larger models need a device with enough free memory — the in-app model list marks which ones fit yours.

With a native build already installed, yarn start boots just the dev server.
