I coded chess.com game review and made it free

Let me know if you have any questions.

There must be a bug; it's not saying my moves are brilliant.
Is there any chance this will be folded in to the LiChess Open Source code?
Good idea.

I just tested it by compare a game review done by SF16 against your tool (with the same deep) and...., I think you need to improve the code because it shows me some moves that are imprecision as good moves and things like that. A move that give you a -0.6 by any means can be a good move, after 2 or 3 moves like that u are lost.

Also, it will be great if you add a sidebar with the move list of the game, engines recommendations, accuracy, moves time, etc... SF17 is not in beta so it will be a great idea to change it also.

Recommendations:

This tool is a great idea, however I think it has no point to waste resources by implementing SF (at least in the game review) in your server to do the analysis. Lichees already are doing that. You can ask for the png of a game review that has been already analyzed and then, according to the advantage changes for each moves, add your icons showing if that move was good or bad. Also, I don't know if the lichess api has access to the opening book, if it is true you can add the icons for the book moves also.

You can make this project as open source and post it at github, so many ppl could help you to improve it.
Great stuff, well done.

I am also working on a chess related web project, so I know how incredibly hard it is to get the UI right, or even halfway decent. It has made me appreciate the immense amount of work that has been done both here on lichess and on the Other Place, both of which feel pretty natural and seamless. Unlike my project, for now :)

I'm not sure whether you want specific bug-related feedback; if you do, I'd strongly recommend something like Github so you can have actual issue tracking, but I did find a couple of UI quirks which would be worth fixing imho.

First, if you accidentally click 'Load' in the middle of a review, there's no way to cancel out of it, so tough luck, you're loading a new game now even if you weren't done with the one you already had loaded.

Second, if you load a PGN from file into 'Review', wait for review to be done, then click 'Analyse', then go back to 'Review', tough luck, you've lost your game and need to reload it.

Still, nice work, and do keep us posted with updates etc as they come.
