Chess Compass
It analyses using Stockfish NNUE. The interface is clean but has plenty of features and customization hidden in pop-up menus.
Most big websites have an analysis feature. Chess.com and Lichess are two of the most advanced. Here another game given to me on Chess.com. This one ends with an explosive tactical combination! Lichess running Stockfish NNUE analyzed the whole game in seconds and does a pretty great job of annotating it. Still you will learn more by annotating it yourself first. Then refer to the computer analysis and see what else was there that you missed.
Important: Convert what you find into your own terms of understanding. You are much more likely to remember what you learn. Also review your losses as well as your wins.
This is an amazing game sent to me on Chess.com. First I analyze as best I can. Then the powerful Stockfish analysis is presented here. What I want you to see is that while computers can tell you exactly where the game was won or lost, and give the exact correct moves. They may not lead to a good understanding of the position, and flow of the game. Analyze your games yourself with your best understanding of what is happening. Then use the computer in improve your understanding. That is much better than trying to memorize a great move from the computer that has no meaning to you.
