I got tired of my chess engine saying “mistake” without telling me why, so I built an app that explains it

Every time I reviewed one of my games, the engine would flag a move as a mistake and show me some line like Nf5. That was it. No reason, no idea behind it. I’d click through the moves for a while, still not get it, and close the tab. So I started building something to fix that for myself, and over the last few months it turned into Plyra Chess. It’s a desktop app for Windows and Mac, and you can use it for free. You load a game and it walks you through the moments that actually decided it

痛点：国际象棋引擎只会标出“mistake”并甩出一串如 Nf5 的变例，却不解释为什么错，业余棋手看不懂也无法转化成棋力提升。

目标用户：Chess.com / Lichess 上的业余棋手（大致 1000-2000 分），有复盘习惯但读不懂引擎线路、想稳定涨分的人

证据：“the engine would flag a move as a mistake and show me some line like Nf5. That was it. No reason, no idea behind it.” / “It’s live now with a free tier and paid plans for people who want more reviews and explanations.”

变现：订阅制：免费每月少量复盘额度，付费解锁无限自然语言讲解、账号弱点周报与个性化训练计划；也可做按次付费的深度复盘包

MVP：两周版：用户输入 Chess.com/Lichess 用户名或上传 PGN → 用 Stockfish 找出失分最大的 5 步 → 调用 LLM 把引擎主变例翻译成 2-3 句人话讲解 + 一句改进建议，输出一页「本周最常丢分的 3 个模式」报告

竞品：Chess.com Game Review、Lichess 内置分析、Aimchess、DecodeChess、Chessable、Plyra Chess（本帖产品本身）

摘要：作者因不满引擎只标“失误”不解释，独自利用业余时间做出桌面应用 Plyra Chess，用自然语言讲解关键局面，并可连接 Chess.com/Lichess 账号生成弱点分析和训练计划，目前有免费层与付费套餐，但未披露任何付费用户或收入数据。帖子本质是竞品发布，侧证了「引擎解释不清」这一痛点真实存在，但 Chess.com、Lichess、Aimchess 等已占据该赛道，竞争空间有限。
