winget install --id=xiaocang.EasydictforWindows -e Windows port of Easydict translation app. Supports 15+ translation services (Google, DeepL, OpenAI, Gemini, etc.), global hotkeys, multiple window modes, clipboard monitoring, and LLM streaming. Self-contained application with system tray support.
A Windows port of Easydict
This is a Windows port of Easydict, originally a macOS translation dictionary app. The project was developed using Vibe Coding - AI-assisted programming to migrate the Swift/SwiftUI codebase to .NET + WinUI 3.
Easydict supports Copilot+ PC enhanced local AI translation: on supported Copilot+ PCs with a 40+ TOPS NPU, translations run on-device via Phi Silica for fast, private output. Foundry Local is supported on regular Windows PCs, with OpenVINO NLLB-200 as an offline fallback — standard translation services remain fully available on every Windows device.
While the feature set is not yet complete compared to the macOS version, this port fills the gap for Windows users who want a convenient translation tool with global hotkey support and multiple translation services.

Copilot+ PC Enhanced Local AI Translation - Windows Local AI runs on-device with NPU acceleration via Phi Silica on supported Copilot+ PCs (40+ TOPS), Foundry Local on regular Windows PCs, or OpenVINO NLLB-200 as an offline fallback. Auto mode picks the best available provider; standard cloud translation services remain fully available everywhere.
OCR Screenshot Translate - Snipaste-style screen capture: press Ctrl+Alt+S to capture a screen region, auto-detect windows or drag to select, then OCR the text and translate. Uses Windows OCR API with configurable recognition language. Also supports silent OCR (Ctrl+Alt+Shift+S) that copies recognized text to clipboard without translating.
Mouse Selection Translate - Select text in any app (drag, double-click, or triple-click) and click the floating pop button to translate instantly in Mini Window
Grammar Correction Mode - AI-powered grammar correction that highlights errors and provides corrected text with explanations
Long Document Translation - Translate PDF, plain text, and Markdown documents with ML-based layout detection, formula protection, parallel processing, bilingual output, and translation cache
Dictionary Mode - Word definitions, phonetics, and example sentences powered by Google Dict and Linguee
MDX Dictionary - Import MDict (.mdx) dictionary files for offline word lookups with rich HTML rendering
