Read the full description

Qi is a native macOS app for reviewing Go games with KataGo. It runs AI analysis locally using Metal acceleration, so you can review your games without relying on a cloud service. You can open SGF files, explore win rate changes, find mistakes, and export game records to PDF for printing or sharing. I built Qi because I wanted a straightforward way to study my own games on Mac. It’s an ongoing project, and I’m working on making game review more useful for players of all levels.

Could you build this?

Yes A native macOS SGF viewer that runs the open-source KataGo engine locally is achievable by bundling the engine binary and writing the UI, SGF parsing, and PDF export in Swift.
