What it does
Runs open-weight language models locally so conversations never leave the device, with builds for desktop and mobile and an OpenAI-compatible endpoint for wiring it into your own tools. Local models are less capable than hosted services, need substantial memory, and on a phone you are limited to small models with noticeable battery cost. Actively developed and still changing.

Atomic-Chat FAQ
- Is Atomic-Chat free?
- The source is open, but the build distributed through the app store may be a paid download. Check the store listing before installing.
- Do I need to install anything or write code to use Atomic-Chat?
- You install it like a normal desktop app. No command line involved.
- Does Atomic-Chat work on a phone?
- No. It needs a computer.
- Can Atomic-Chat 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 Atomic-Chat 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.
