-0047B3?style=for-the-badge&logo=windows&logoColor=white){kind=icon}
A full-featured screenshot, annotation, OCR, translation, screen-recording and sharing tool for Windows. CyberSnap combines a floating capture widget, an annotation editor, multilingual text recognition, local image search, video trimming, and multi-destination upload, all in a single .NET 9 / WPF desktop application.
Free and open source (GPLv3): no ads, no tracking, and no data collection. Just enjoy it.
Most screenshot tools either do too little or bury features behind a paywall. CyberSnap gives you professional-grade capture, editing, and sharing, including OCR, translation, and 7 upload destinations, all in a free, open-source package with a polished, modern design.

Download the Inno Setup installer and follow the wizard. The installer registers .csnp file associations, creates shortcuts, and offers to start with Windows.
Windows may show a SmartScreen warning the first time you run the CyberSnap installer: this is an unsigned hobby app, so Windows hasn't built reputation for the file yet. This is expected; the source is public so you can inspect exactly what it does. The same can appear when launching the portable build.

Originally forked from OddSnap by jasperdevs. CyberSnap has since been extensively rewritten and expanded by CyberGems.
This project also builds on open-source components including Tesseract OCR, ZXing, SQLite, and Inno Setup, thanks to their authors and maintainers.
I’ve spent countless hours building and refining CyberSnap for my own use. I recently decided to share it with the world as part of the CyberGems set of free and open-source tools.
If you’d like to support future updates, I’d truly appreciate it. You can also show your support by starring the repo on GitHub. Thank you! 🙏
