Analyze with Chess Masti

Analyze with Chess Masti — your post-mortem starts in one click. Stop letting your blunders die undiagnosed. Stop copy-pasting PGNs. Stop wishing you had a coach. The extension you've been waiting for slips into Lichess and Chess.com, sits quietly in the top nav, and — the second your game ends — opens a real, live, talking AI chess coach with your game already on the board. Free. No account. No paywall. No "you've used 3/10 analyses this month." Just chess. ──────────────────────────────────────────── THE PROBLEM EVERY CHESS PLAYER HAS HAD You just lost a 50-move bullet game on Lichess. The blunder was somewhere around move 28 but it could have been move 14 — you don't actually know. The "Rematch" button is right there. So is "New Opponent". So is "Tournament". So is the rabbit hole. You don't analyze. You click rematch. You lose again, faster. You know — somewhere in the back of your head — that the games you play and don't review are wasted reps. That you're not getting better, you're just paying the rating-points tax for the same mistakes. But analysis is friction: you have to find the share button, copy the PGN, find a tool, paste it, click around. By the time you've done that, the next game has started and the question you cared about — "why did I blunder that?" — is gone. That's what we got tired of. So we fixed it. ──────────────────────────────────────────── WHAT THIS EXTENSION DOES, EXACTLY A single orange button — "♟ Analyze with Chess Masti" — slides into the top navigation bar of every Lichess and Chess.com game page. Between DONATE and the search icon on Lichess. In the equivalent slot on Chess.com. The button does ONE thing: when you click it, your game opens for AI coaching on chessmasti.com in a new tab. Behind the curtain, three things happen in maybe a hundred milliseconds: → The extension recognizes you're on a game page (not a profile, not a forum, not a homepage). → It reads the PGN of the game — from Lichess's public game-export API on lichess.org, or directly from the moves panel on chess.com. → It opens chessmasti.com/analysis with your PGN already loaded, and your coach is waiting. No popup. No settings. No background script. No remote server of its own. It is, by design, the smallest possible extension that turns "I should analyze this" into "this is being analyzed." ──────────────────────────────────────────── THE COACH YOU CAN ACTUALLY TALK TO This is not a "move classifier." Chess.com's built-in Game Review will tell you that move 14 was a Blunder, that move 7 was Excellent, and that your accuracy was 78%. It will not tell you why. It will not answer follow-up questions. It cannot. Chess Masti is a chat. You type "why did I lose move 14?" and the coach answers — grounded in the actual position, with the actual engine evaluation, in plain English calibrated to how you like to be taught (you set the tone in your profile: serious, friendly, brutal, whatever). → Ask why a specific move was a blunder. → Ask what tactic you missed. → Ask "what should I study based on this game?" → Ask "would my opening have held up if my opponent had played sharper?" → Ask "show me the endgame technique I should've used." → Ask anything. The coach has access to every move, every Stockfish evaluation, the full game tree, your saved coaching preferences, your favorite openings, and your study goals. It answers like it's been watching your chess for years — because by the third game, it has. ──────────────────────────────────────────── THE THING NOBODY ELSE HAS: A HALLUCINATION VALIDATOR If you've ever used an LLM-based chess tool, you've watched it confidently tell you that "your knight on f3 attacks the bishop on d5" when there is no knight on f3. LLMs lie about chess constantly. They invent pieces, fabricate threats, invent illegal moves with the same easy confidence they use for the moves that actually exist. We built a layer that catches this. Every single response from the coach — every paragraph, every move reference, every piece-and-square claim — is parsed and checked against the live chess.js board state before it ever reaches you. Claims that don't match reality get rewritten or discarded. The response you read is the response that's actually true. This is the difference between a chess coach that sounds confident and one that's actually correct. It's the difference between "wow this AI is amazing" and "wait, that's not actually what happened." It's the work everyone else skips because it's annoying to build. We built it anyway, because we care about being right. ──────────────────────────────────────────── INSIGHTS YOU CAN SHARE WITH ONE LINK After the coach finishes its initial walkthrough, every critical moment of the game becomes its own insight card — a discrete unit of "here's what happened on move 14, here's why it mattered, here's what to study next." Each card has its own permalink. Send your friend the link to your move-14 blunder card. They click it. They see exactly what you saw — the position, the engine evaluation, the coach's explanation — without anyone paying for a fresh AI call. The whole experience is built for sharing because chess is more fun when you can show someone the exact moment you got mated. ──────────────────────────────────────────── PUZZLES BUILT FROM YOUR ACTUAL BLUNDERS After a coaching response, three puzzles render directly inside the chat bubble. Same board, same UI, no navigation away. They are not generic. They are picked from a curated graph database of over 100,000 Lichess puzzles — quality-filtered for popularity, play count, and rating-deviation tightness, structured across 46 tactical themes and 4 difficulty bands — and then re-ranked by FEN cosine similarity to the position you just got wrong. In English: the puzzles you get are the puzzles that look like your mistake. You solve three of them. The next time the pattern shows up in a real game, your hands know it. ────────────────────────────────────…
