Getting a "can't verify the developer" warning?

If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.

Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.

Risk notice

The eSearch installers are not distributed through official app stores and are not signed by Apple or Microsoft. Windows SmartScreen or macOS Gatekeeper may show warnings. Please download only from official GitHub Releases or our site, and verify the SHA-256 checksum before installation. If you do not trust the source, do not install. Additionally, because it bundles Electron and AI models, the installer is large and may consume significant memory on lower-end devices.

Who it's for

Users who need a powerful screenshot tool with OCR, translation, and search in one
Linux desktop users looking for a full-featured screen capture alternative
Designers or writers who rely on pinning reference images for comparison
Content creators needing screen recording with cursor and keystroke overlay
Privacy-conscious users who prefer offline OCR processing

Who it's not for

Users who just need a lightweight screenshot utility and want minimal storage footprint
People still running Windows 7 or 8 (no longer supported)
Those who demand a native macOS experience and are sensitive to resource usage
Users with very limited disk space due to the large install size (Electron + AI models)

Install guide

Installation Guide

Choose the Right Package

Select the appropriate file based on your operating system and CPU architecture (usually x64; choose arm64 for ARM-based devices).

Windows
Recommended: eSearch-15.3.4-win32-x64.exe (x64) or eSearch-15.3.4-win32-arm64.exe (arm64)
Alternatively, grab the .zip archive and run eSearch.exe inside.

Linux
Recommended: eSearch-15.3.4-linux-x64.AppImage (x64) or eSearch-15.3.4-linux-arm64.AppImage (arm64)
Other formats: .deb (Debian/Ubuntu), .rpm (Fedora/openSUSE), .tar.gz (universal)
For AppImage: make it executable with chmod +x eSearch-15.3.4-linux-x64.AppImage, then run it.

macOS
Apple Silicon (M1/M2 and later): eSearch-15.3.4-darwin-arm64.dmg
Intel chip: eSearch-15.3.4-darwin-x64.dmg
The corresponding .zip files are also available.

Installation Steps

Windows: Double-click the .exe and follow the wizard.
macOS: Open the .dmg, drag eSearch.app into the “Applications” folder.
Linux: Install .deb with sudo dpkg -i <file>.deb; use sudo rpm -i <file>.rpm for .rpm; extract .tar.gz and run the binary inside.

First Run

eSearch sits in the system tray after launch.
The default screenshot hotkey is Alt+C (changeable in settings).
Some Windows systems may prompt you to install a dependency library on first launch. Click to download and install from Microsoft, then restart.
On macOS, if you see “cannot verify developer” or “damaged” warnings, go to “System Settings > Privacy & Security” to allow it, or right-click the app and select “Open”.

FAQ

Is eSearch free?

Yes. eSearch is open source under the GPL-3.0 license and completely free to use, with no built-in purchases or ads.

Which operating systems are supported?

eSearch supports Windows 10/11, mainstream Linux distributions, and macOS Catalina or later. Windows 7/8 are no longer officially supported.

How do I update to a new version?

Download the latest installer from GitHub Releases or OpenSoftHub and overwrite the existing installation, or uninstall first then reinstall. Consider backing up your settings first (settings can be exported).

Does offline OCR require an internet connection? What about online translation?

The built-in OCR runs completely offline. Searching, online translation, and cloud-based OCR services require network access. You can also download larger language models in settings.

What should I do if macOS says the app is “damaged” or cannot be verified?

This is a common warning for unsigned apps. Refer to the README: in “System Settings > Privacy & Security”, allow it to open, or right-click the app and choose “Open”. The exact steps vary by macOS version.
