Yo I just tried chess.day and lowkey it’s kinda awesome 🤯
Took about 1:30 for the main review, then a tiny wait at the end (~30 sec) to hit 100%
Loved the Top 3 Best Moves feature, makes you feel like a pro for once
Animations while loading are actually kinda satisfying
The review itself felt solid, really liked seeing both good plays and blunders highlighted
Would love to see maybe a faster load for super long games, but honestly still pretty dope. Definitely gonna save my games there
Thanks brother, means a lot. If you want to speed up the analysis choose 1 best move option, then only the best moves will be shown in game reviews but it speeds up the time of analysis a lot. The 3 best move option needs more time, it's cool if you want to see what other decent options you could play but if you need only best moves to show and like speed them i advice to use option for best moves in game reviews only to speed it up.
PS. If you want the games to be auto saved to library, just log in and all the games will be stored in Library automatically. 
I build website where you can generate free game reviews of your chess.com or lichess.org games and store them in one place, you can try it on "chess.day". Let me know what you think 🤔
