Friend: Open-Source AI Wearable with 24h+ on single charge

Assembled	Dissembled

 

Friend is an AI wearable device that records everything you say, gives you proactive feedback and advice. Features:

• Real-Time AI Audio Processing: Leverage powerful on-device AI capabilities for real-time audio analysis.
• Low-powered Bluetooth: Capture audio for 24h+ on a small button battery
• Open-Source Software: Access and contribute to the pin's software stack, designed with openness and community collaboration in mind.
• Wearable Design: Experience unparalleled convenience with ergonomic and lightweight design, perfect for everyday wear.

Structure

There are 2 different apps in these repositories located in different branches and folders. Our goal is to merge them into one big project.

• Standalone Branch or Folder "AppStandalone": Standalone version of the app that doesn't require any hardware to use it. Try example here used by thousands of people.

• AppWithWearable Branch or Folder "AppWithWearable": Wearable-connected version of the app that requires the "Friend necklace" to use it.

• [Main Branch] Branch that contains firmware, hardware, designs and both apps
