📦 Installation

The following covers how to obtain, run and extend the software; see Native/README.md for details:

Software Download

Go to SnowAir Releases, expand Assets, download SnowAir.exe, and double-click to run — no installation required.

Configuration, language and plugins live in %AppData%\SnowAir\ by default; to keep them next to the program instead (so you can move the whole folder to a USB drive and keep your settings), place an empty file named config.json next to SnowAir.exe — delete the file to restore the default.

Open-Source Scope

SnowAir itself is open source under the Apache License 2.0. It depends on a customized Ling branch with unpublished implementation, which is not distributed here, so building from this repository alone is not supported.

To run SnowAir, download SnowAir.exe from SnowAir Releases.

Offline Components

Includes offline OCR, offline translation and other components, downloaded on demand and not bundled with the installer: you can download the required components and language packs under "Plugin Integrations", then enable them in "Feature Settings" to recognize Chinese, English and UI screenshots offline — no internet connection needed, and the engine is released as soon as it is done, so it never holds memory long-term.

Command Line

When launched without arguments, it **only sits in the system tray on standby** and does not automatically enter capture mode:

SnowAir.exe                     # Tray standby, default
SnowAir.exe --auto-quit=true    # Quit right after capturing
SnowAir.exe --enter=pin         # Enter pin after selecting a region
SnowAir.exe --enter=long        # Scrolling capture
SnowAir.exe --enter=video       # Screen recording
SnowAir.exe --enter=tray        # Tray only, same as default behavior

Capture entry points: click the tray icon, and choose capture / open settings / do nothing under "Feature Settings → Tray Single Click"; or use the global hotkey F1; running the exe again opens the settings center.

✨ What's New

🛣️ Roadmap

Keep refining annotation and screen-recording capabilities, improve OCR / translation service integration, and advance the settings center and toolbar appearance editor.

🔒 Privacy Statement

SnowAir is a local tool and does not upload any screenshots or text by default; network access is used only for checking updates, online OCR / translation services, and plugin downloads.
