Yes there is. Go to live chess and find the analysis board. From there paste your pgn and click on start(go). This will show the game as if you've just finished playing a live game. You can choose to analyze from there.
To copy the text from your pgn file open it with a text editor such as notepad, or google docs if you're on android. Or you could just copy as is from whichever site you were playing the game.
Hey guys, do you know if I can upload pgn to chess.com for accuracy check?? Is there a way to do this if the game was played on another website?
