## FAQ
### What does Quell-Code do?
Quell-Code is a software engineering company focused on artificial intelligence. We build AI agents, RAG systems and automations, install local language models and develop web and mobile apps as well as the server infrastructure behind them.

### Can AI models run locally without the cloud?
Yes. Open language models can run on your own hardware. We pick model size and quantisation to match your server or GPU, connect your documents via RAG and deliver an internal interface or API — with no data flowing to third parties.

### Which technologies does Quell-Code use?
Among others Python, TypeScript, JavaScript (React, Vue, Nuxt, Next.js, Node.js), PHP/Laravel, Kotlin, Java, Swift, Objective-C, Dart/Flutter, React Native, Lua, T-SQL, MySQL, MongoDB, SQLite, TensorFlow.js, OpenCV, WebSockets, Asterisk and Linux and Windows servers.

### How does a project start?
With a no-obligation conversation about your goal and starting point. You then receive an assessment of feasibility, architecture and effort. We build in short iterations with working increments.
