This is the official Snow Shot repository, maintained by mg-chao. The repository is named Snow Apps because it also contains Snow Image Viewer and shared libraries. The previous mg-chao/snow-shot address redirects here. The official website is snowshot.top.

Get packages from GitHub Releases. The official download page helps select an architecture and also provides the maintained Gitee mirror.

Choose the full edition for text, table and QR recognition. The Windows offline installer includes the default OCR resources. Choose Mini for a smaller package focused on capture, annotation, pinning and recording; text OCR resources download when needed, and table/QR recognition is omitted. Mini has no offline installer. See package selection and setup.

Windows users can also install from the Microsoft Store.

Download the installer from Snow Shot releases. Install the offline Windows x64 package from the WinGet community repository with:

winget install --exact --id mg-chao.snow-shot --source winget

This package includes published beta versions and the default OCR resources. See WinGet release support for upgrades, removal, and maintainer setup.

Install the portable package with Scoop from the official Extras bucket:

scoop bucket add extras
scoop install extras/snowshot

The Scoop package follows stable releases and includes the default OCR resources. Quit Snow Shot before running scoop update snowshot; use Scoop rather than the app's built-in updater. Settings and history persist across upgrades and ordinary uninstall. See Scoop release support for removal, data locations, and maintainer setup.

Apple silicon and Intel Macs running macOS 15 or later can install the stable full edition with:

brew update
brew install --cask mg-chao/tap/snow-shot
brew upgrade --cask snow-shot
brew uninstall --cask snow-shot

Installation reuses Snow Shot's local signing identity and may request Keychain access and macOS privacy permissions. See Homebrew installation and migration for existing installations, custom app directories, and recovery.

1. Launch Snow Shot. On macOS, grant screen recording permission when requested.
2. Press F1, select a region or window, and use the toolbar to annotate it.
3. Copy, save or pin the result. Ctrl+F1 (Command+F1 on macOS) starts a capture that copies the confirmed selection directly; F3 pins clipboard content.

These are the default shortcuts. If your keyboard uses function keys for media controls, use Fn or assign another binding in Snow Shot's shortcut settings. Existing custom bindings take precedence. Read the step-by-step guide for setup and troubleshooting.

Yes. Snow Shot is licensed under GPL-3.0-or-later. The repository contains other components under their own licenses; see the license table below.

Standard text recognition runs locally once its model resources are installed. For an offline Windows setup, choose the full offline installer. Translation and optional online or AI features have separate network and provider requirements. See offline OCR and the privacy policy.

The published desktop packages currently target Windows and macOS. There is no official Linux package. Source availability does not imply Linux runtime support.

Use this repository's Releases or snowshot.top. Forks and third-party download sites may describe older versions. Report problems against the version and package you actually installed.

Snow Apps contains the Snow Shot app (snow_shot/), Snow Image Viewer (snow_image_viewer/), shared Qt/C++ libraries, and Rust components in snow-crates/. See AGENTS.md for build commands and repository rules, Windows ARM64 build support, and macOS build support. User documentation lives in docs/guide/.

snow-crates/crates/simd-paddle-ocr-rs/ is a Git submodule with its own repository, history, branches, and releases. Snow Apps records the exact OCR commit to check out. The submodule is excluded from the Snow Crates Cargo workspace so it retains its own pinned nightly toolchain and lockfile. Run its Cargo commands from the submodule directory.

After cloning Snow Apps, initialize the submodule from the repository root:

git submodule update --init --recursive

For a new clone, git clone --recurse-submodules initializes it automatically. Submodule updates normally check out a detached HEAD. Before editing OCR code, switch to main or a feature branch inside the submodule:

git -C snow-crates/crates/simd-paddle-ocr-rs switch main

Follow the submodule's README and AGENTS.md for its build and validation commands. Commit and push OCR changes to its own repository first, then record the new revision in Snow Apps:

git add snow-crates/crates/simd-paddle-ocr-rs
git commit -m "build(ocr): update simd paddle ocr submodule"

This is a multi-license repository. See LICENSE.md for the repository-level scope rules and third-party material policy.

Synchronized and bundled third-party materials retain their upstream licenses. See Ant Design Qt third-party notices and Snow Shot third-party notices.
