What it does
Runs language models, image generation and speech recognition on the device itself, with acceleration for Snapdragon and similar chips, so nothing needs a connection and nothing leaves the handset. Android only. Phone-sized models are noticeably less capable than desktop or cloud ones, image generation is slow enough to be impractical on many devices, battery drains quickly and the models themselves take several gigabytes.

Box FAQ
- Is Box free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use Box?
- You install it like a normal desktop app. No command line involved.
- Does Box work on a phone?
- Yes, it works on a phone.
- Can Box run offline?
- Yes. Everything happens on your own machine, so your data is never sent to an outside server. That makes it usable for material you cannot share externally.
- Can I use Box commercially?
- The project does not state a clear licence, so commercial use cannot be confirmed here. Check the official page or ask the author before using it at work.
