Frequently Asked Questions

Why does EiSen require macOS Screen Recording permission?
To capture pixels outside of its own window, macOS security architecture requires explicit Screen Recording access. EiSen operates entirely on-device and never sends screenshots, OCR text, or analytics over the network.
Is EiSen compatible with Apple Silicon and Intel Macs?
Yes! The current release v0.1.1 is compiled specifically for Apple Silicon (M1, M2, M3, M4 and newer) on macOS 11.0+. Universal and Intel builds are supported by building from source or subsequent release updates.
How does the OCR feature work without an internet connection?
EiSen uses Apple's native Vision framework via high-performance Rust bindings. It leverages the Apple Neural Engine directly on your Mac, delivering blazing fast OCR without a single byte leaving your computer.
Why doesn't EiSen appear in my Dock?
EiSen is configured as a macOS Accessory Application. It lives quietly in your menu bar (status bar) at the top of your screen to stay out of your way until you need it.
How do I update to newer versions of EiSen?
To maintain zero background network activity, EiSen intentionally does not include an automatic background updater. Simply download the newest DMG release from GitHub or via eisen.a302.link/download.
