  You could try
  
  [PGN ChessBook](https://pgnchessbook.org/)
  
  Which is a free app that can be installed from SourceForge or from the Windows app store.
  
  It finds blunders, then automatically annotates games by inserting variations and adding comments to the blunder moves, as described on
