ScreenLingo

Project Overview

ScreenLingo is a Windows desktop tool focused on local screenshot OCR, error translation and screenshot Q&A. Select an English code error on screen and release the mouse to get local recognition and a translation, making English errors easy to understand quickly. Built with Electron, its OCR runs locally and normal translation only sends the recognized text; to keep asking about a screenshot, you can configure an OpenAI-compatible vision model.

Select an English error and see the explanation in Chinese the moment you release the mouse.

Key Features

• Screenshot translation: Alt+Shift+S to select and translate, with local OCR plus online translation
• Clipboard translation: Alt+Shift+T translates already-copied text directly
• Screenshot Q&A: keeps asking about the error cause or fix direction; requires a vision model
• Adaptive networking: detects v2rayN proxy or direct connection automatically, or set it manually
• Tray resident: stays in the system tray after closing, ready whenever you need it

Target Audience

• Developers who frequently deal with English code errors
• Learners and office workers who need quick on-screen translation
• Local developers working in v2rayN proxy environments

Quick Start

1. Download the latest version from Releases, unzip and run 截译 ScreenLingo.exe
2. Choose a translation service in Settings on first use
3. Press Alt+Shift+S in any window and drag to select an English error
4. Release the mouse and wait for the local OCR and translation result

Core Advantages

• Local OCR: recognition runs on your machine with a bundled English model, balancing speed and privacy
• One-shot translation: one shortcut from selection to result
• Proxy adaptive: works whether v2rayN is on or off, with no manual switching

Notes

• Screenshots are sent to the vision model only when you actively use "screenshot Q&A"; normal translation sends text only
