Free and Simple Chess Analysis

experimentally built chess analysis app as a hobby project: g6chess.com

early alpha for now, with the main idea to keep it simple and easy to navigate for every player level (better use desktop for now)

to simplify the use, you can inject the "g6" before any chess.com or lichess.org game you just played and press enter. I own both g6chess.com and g6lichess.org domains so we'll get your redirect right to the analysis page built on top of my previous opensource involvements: ultrachess and ultrachess-React. explanation backend is closed-sourced for now, a bit too early for public, but planning to opensource it eventually too

main challenge is to make thoughtful formulas for move labeling, as it tends to overuse 'blunder' and 'best' when the settings are too rigid; and it's kinda tricky to train the LLM to explain the moves, even with comprehensive context. my personal impression is that taketaketake do it the best, but I spent just a few days for now, so we'll see where we end up

happy for any feedback and ideas:)
