Capture Engine

Smart Crop & Instant Multi-Monitor Selection

Trigger with double-tap Option (⌥⌥) on Mac, or PrintScreen (PrtScn) on Windows. If PrintScreen is occupied, EiSen automatically uses Ctrl + Shift + 5. EiSen targets the display under your cursor, lets you nudge the crop with arrow keys, and exports crisp PNGs.

  • ✓ Fine-tune crop dimensions with keyboard arrows
  • ✓ Multi-display aware with zero coordinate offset bugs

Frequently Asked Questions

Does EiSen support both macOS and Windows?
Yes! Starting with v0.2.0, EiSen is fully cross-platform with first-class support for macOS (macOS 11.0+ on Apple Silicon and Intel) and Windows (Windows 10 and Windows 11 64-bit). Both platforms benefit from native capture pipelines, native on-device OCR, and instant zero-latency performance.
Why does EiSen require macOS Screen Recording permission?
To capture pixels outside of its own window, macOS security architecture requires explicit Screen Recording access. On Windows, no such permission prompt is required. On both systems, EiSen operates entirely on-device and never sends screenshots or data over the network.
Is EiSen really a 100% free alternative to CleanShot X, Shottr, and ShareX?
Yes! EiSen was created specifically as a free, open-source, privacy-first alternative. It provides clean menu bar/system tray captures, pixel-level magnification, numbered step annotations, redaction blur, and instant offline OCR without paying $29+, buying monthly subscriptions, or configuring 100 overwhelming menus.
How does OCR work on Windows without cloud APIs?
On Windows, EiSen leverages the native Windows.Media.Ocr engine via modern WinRT bindings. On macOS, it uses Apple Vision and the Apple Neural Engine. Both engines process text 100% locally on your machine with zero cloud connectivity and zero cost.
Can I customize hotkeys on Windows?
Yes! EiSen on Windows prefers PrintScreen (PrtScn). If Windows or another app already owns that key, EiSen automatically switches to Ctrl + Shift + 5 and shows both supported choices in Settings.
How is EiSen different from traditional screenshot apps or cloud capture tools?
EiSen is a native Rust screen capture utility that works offline and keeps screenshots, OCR text, and annotations on your computer. The v0.2.5 Windows NSIS fallback download is 2,599,622 bytes (2.60 MB); this is the installer file size, not the installed app size. Microsoft Store package size varies.
How do I update to newer versions of EiSen?
Windows installations from Microsoft Store receive Store-managed updates. The direct NSIS installer and macOS DMG do not include an auto-updater; download newer direct releases from GitHub or eisen.a302.link.

macOS

Version 0.2.6 • Apple Silicon • DMG download 4.37 MB • macOS 11.0+

Windows

Version 0.2.5 • Windows 10/11 (64-bit) • Microsoft Store • Direct unsigned NSIS fallback

Windows direct-download note

The Microsoft Store version is the recommended Windows install and receives Store-managed updates. The direct NSIS .exe fallback is unsigned, so SmartScreen may show Unknown publisher or Windows protected your PC, and managed devices may block it. Verify the SHA-256 sidecar on GitHub Releases before running.
