Chess Muscle Developed by people who really care about their users, Chessify has the horsepower to do chess analysis no PC can. I'm currently analyzing with over 1000 cores, all working silently online!

I paid a subscription but I spend time sending bug reports... The chessify website offers users the option to store chess files in pgn format and analyze games with very strong cloud based chess engines. Although the idea is good, the implementation so far is rather poor with the pgn user interface still in development and very buggy. When I informed their tech service of my problems, I was asked to record my screen and the bugs ! I was already a paying customer ! So if you feel like paying a membership to help chessify debug their user interface, this is the site for you ! I recommend waiting 1 year or 2 until their product is stable before spending any money on Chessify. At the moment, it's still very much work in progress...

Very helpful!!! Very helpful!!! Chessify is very helpful for a tournament player. It offers lots of features for preparation, tho I particularly appreciate their cloud analysis which is the strongest I've ever seen. I also like that they're improving their website now and you can use different chess databases when preparing openings. I recommend it to anyone trying to improve their game.

Reliable Cloud Engine Chessify offers some powerful cloud engines that make chess analysis a lot more efficient--very useful tool for professional players. Their new database web app is also quite promising as a place to store opening files/analyses. The team is quite dedicated and extremely responsive as well.

Chess site review Excellent chess website with tons of games and amazing analysis possibilities despite the lag!
