About

What is pi-card?

pi-card is an open-source project designed to create an AI-powered voice assistant running locally on a Raspberry Pi. It functions similarly to standard LLMs like ChatGPT in a conversational setting, but operates completely offline. Users can interact with the assistant using a customizable wake word or a physical button connected via GPIO. The system supports configurable conversation memory and can be enhanced with a camera to describe images and answer questions about them. It leverages cpp implementations like whisper.cpp for audio transcription and llama.cpp for vision capabilities, aiming for efficiency on Raspberry Pi hardware. Docker support is provided for easier setup, making it accessible for developers and hobbyists interested in local AI projects.

Best used for

Ideal for developers and students who need to build a custom voice assistant, run AI models locally on a Raspberry Pi, and experiment with offline conversational interfaces. Especially valuable for those interested in edge computing and hardware-integrated AI projects.

FAQs

What hardware is required to run pi-card?

To run pi-card, you will need a Raspberry Pi (preferably a Pi 5 Model B), a USB microphone, and a speaker. A camera and a camera connector are optional for vision capabilities, and a breadboard with a button is needed for button-based interaction.

Can pi-card operate completely offline?

Yes, pi-card is designed to run entirely on a Raspberry Pi, making it capable of operating completely offline. All conversational and vision processing is done locally on the device, without relying on cloud-based systems.

How can I customize the wake word for pi-card?

The wake word for pi-card can be customized by modifying the `config.py` file within the project. The default wake words include "raspberry," "barry," and "razbear," but you can change them to anything you prefer to personalize your assistant.
