DeepLocal is a clean WPF desktop app that brings DeepL-style translation fully offline via Ollama. Two-pane UI, auto-detect, swap, and model picker (default: gemma3:12b). Built with .NET 8.
Interface inspired by DeepL: two panels (source → translation)
Auto-detect of the source language (the selector automatically switches to the recognized language)
Coherent swap (swaps texts and languages without forcing English)
Ollama model selector (default gemma3:12b; mistral:latest, aya-expanse:8b, gpt-oss:20b, gpt-oss:120b-cloud)
Quick actions: Paste, Copy, Translate
Tray app: starts minimized, double-click to show/hide, right-click menu
Window position anchored to the bottom-right when it reappears from the tray
Main supported languages (IT, EN, ES, FR, DE, PT, RU, HE, JA, ZH). For unsupported languages: “language not supported”
Windows 10/11
