Where this sits among the 47 tools we list in Local AI
- Works without using a terminal27 of 47
- No API key required45 of 47
- Keeps your data on your own machine34 of 47
- Runs on a phone alone3 of 47
Only 2 of the 47 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
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?
- We could not confirm this. The publisher does not state it clearly, so we have not verified whether what you make with it may be used commercially. Ask the publisher before relying on it.
