Fullmoon is an open-source app that brings a local AI to your iPhone, iPad, Mac, and Vision Pro. This app allows you to use AI chatbots like Claude or ChatGPT on the go without relying on cloud servers from Anthropic or OpenAI. Instead, Fullmoon uses an open AI model, which is easy to set up and use.
Upon starting Fullmoon, you need to select an AI model. The options are limited to two versions of Meta’s free AI model, Llama 3.2. After downloading the model, you can start asking questions immediately. Even on an older iPhone 13, responses are quick and without noticeable delay.
The interface of Fullmoon is similar to other AI chat apps, featuring a text field for prompts and a menu to switch between different chat sessions. However, unlike apps from OpenAI or Claude, Fullmoon lacks features like file uploads and voice output. It also cannot generate images or perform web searches. Despite these limitations, Fullmoon provides solid answers in both English and German.
Fullmoon can be integrated into Apple’s Shortcuts, allowing you to automate tasks with custom prompts, even without an internet connection, since the AI runs locally on your device.
While Fullmoon is not a full replacement for ChatGPT due to its limited functionality, it is a useful tool for those who want access to a large language model without privacy concerns. For desktop users, there are more powerful alternatives like LM Studio, which might be slightly more complex to use but offer greater capabilities.
Overall, Fullmoon is a convenient option for mobile users who prioritize privacy and want a local AI solution. It works smoothly on both mobile and desktop platforms, though exploring other tools may be beneficial for more advanced needs.
