One place to review all my chess games

[Picasso]

I play chess on both Chess.com and Lichess depending on who I'm playing with, and reviewing games has become a bit of a mess. One site gives me one style of analysis, the other gives me something different, and sometimes I just have a PGN from somewhere else. I'd rather use the same review for everything and see move grades, accuracy, the evaluation graph, and explanations without worrying about how many games I've already analyzed that day. Is there a free analyzer where I can keep reviewing games from different sources without hitting a daily limit?

You could also run Stockfish locally if you don't mind a more basic interface. A desktop GUI like Scid vs. PC will take PGNs from anywhere and you can analyze as many games as you like, since nothing is tied to an account or daily quota. You won't get the same polished explanations as some web tools, but for unlimited engine analysis it does the job.

Some analyzers throw a wall of engine lines at you and call that a review, which isn't all that useful unless you already know exactly what you're looking for. It's a lot better when the tool actually walks through the game and gives you something readable instead of making you decode everything yourself. You can do unlimited chess analysis for free here: https://chessgrader.com/ . You can bring your games over regardless of where you played them, so there's no need to jump between different review systems. And you can keep working through a whole batch in one sitting rather than getting cut off after a handful of games.
