A cross-platform desktop PDF reader with Gemini translation

Download pre-built binaries from Releases page.

• macOS: Download .dmg file
• Linux: Download .deb or .AppImage file
• Windows: Download .msi file

Pedaru is not signed with an Apple Developer certificate. When you try to open the app, macOS may show an error saying the app is "damaged" or "can't be opened".

To fix this, run the following command in Terminal before opening the .dmg file:

xattr -r -d com.apple.quarantine Pedaru_x.x.x_aarch64.dmg

This is a temporary measure until the app is properly signed.
