OstiumIAtrad is a lightweight Windows desktop app that translates text using a small AI language model running entirely on your own machine or local network — through Ollama, LM Studio, or any other OpenAI-compatible local server. No cloud API keys, no per-word pricing, no text ever sent over the internet.

It’s built for people who want quick, private translations without routing every sentence through a third-party service.

Features

• 100% local inference — every request goes to an AI server on your own machine or LAN; nothing is ever sent to the cloud
• Streaming output — the translation appears token-by-token as the model generates it, instead of a blocking wait
• 29 languages, plus automatic source-language detection
• One-click swap between source and target language (and text)
• Bring your own engine — works with any OpenAI-compatible local server: Ollama (recommended), LM Studio, llama.cpp’s server, text-generation-webui
• Live model picker — refresh and choose from whatever models are installed on the connected server
• Dark, modern interface, built natively in WinForms (no Electron, no runtime overhead)
• Zero external dependencies — no NuGet packages; only assemblies that ship with .NET Framework
• Portable settings — a small JSON file under %AppData%, nothing written to the registry
