Why did that move lose?
Paste a game from Lichess, Chess.com or your own notation and see what each move cost — and which part of the position paid for it.
Moonforge scores positions from named terms — material, king safety, pawn structure, mobility — so a review can say which of them a move gave away. Engines built on neural networks cannot: their evaluation is a single number with no parts to name. Nothing you paste leaves your browser.
