Your position after 29. Qd2. Black is already pressing.

Stockfish + Maia. Objective meets human.
Stockfish finds the best move. Maia models how humans actually play. Together they pinpoint the moments that decided your game — not just the blunders.
Key Moment Identification
A living picture of your game.
After every review, the coach updates what it knows about you: the habits costing you games, the strengths you can lean on, the leaks you're closing. By week three, it's naming progress you hadn't noticed.
“Three weeks ago you were collapsing your king’s cover in every endgame. I haven’t seen it once in your last 9 games. You fixed it — and your rating climbed 47 points while you weren’t counting.”

Practice on the positions you actually lost.
Every weakness the coach finds comes with a drill built from your own games — the exact move where it went wrong. Try again, and see what your move really does. Then the coach hands you the two or three things to keep in mind before you play.

By week three, it's naming progress you hadn't noticed.
EloCoach keeps a living picture of how you play: the habits costing you games, counted game by game; the strengths you can lean on; the losses each pattern actually decided. Every review starts with the coach already knowing your history, so you never re-explain yourself. And when a weakness finally disappears, it's the first to point it out.
It also knows the difference between a hunch and a confirmed pattern — a single odd game gets watched quietly, not announced as a flaw, until it actually repeats.
Seeing your own progress named back to you is what makes the work feel worth it.

Battle story · Tactical · Game-aware
Reads each game as a battle: where the pressure started, where it cracked, and the one move that decided it. Remembers your habits across sessions, and gets sharper every time you play.
“What’s costing me the most rating points right now?”
“Middlegame impatience. You’re pushing for the win before the position is ready — three games this week were winning at move 25 and gone by move 35. That’s not endgame technique, that’s a decision pattern. Let’s fix the leak.”
ApolloLive
Principled · Structural
Coaches through the laws of chess, not just moves. Every recommendation traces back to a named principle, and to rules of thumb you can use in any position.
“I played 3.Qh5 to attack early. It felt aggressive.”
“Development before attacks — always. Your queen came out on move 3 and spent four moves running from threats. Two principles broken in five moves. Let's rebuild from the first pawn.”

Frequently asked questions.
What is EloCoach?
EloCoach is an AI-powered chess coach app. Connect your Chess.com or Lichess account and EloCoach analyzes your real games, then coaches you in natural conversation — remembering your habits, goals, and progress across every session, not just the game in front of it.
How does EloCoach analyze my games?
EloCoach combines two engines: Stockfish finds the objectively best move in any position, while Maia — trained on millions of human games — predicts what a player at your rating would actually play. Comparing the two pinpoints the moments that actually decided your game, not just the biggest blunder.
Which chess platforms does EloCoach connect to?
Chess.com and Lichess. Sign in with Lichess or add your Chess.com username once, and EloCoach automatically pulls in your recent games — no PGN files to upload or export.
What makes EloCoach different from a normal analysis board or engine?
A standard engine gives you a static evaluation and moves on. EloCoach keeps a persistent memory of you across sessions — it tracks recurring habits, the goals you've set, and the weaknesses you're closing, and calls out real progress (“you haven't made that mistake in 9 games”) instead of starting from zero every time you open the app.
What does a game review actually look like?
Tap a game and the board comes up with the analysis running underneath — that part is free and unlimited, every game. When you spend a coach diagnosis on it, you can start reading the coach's take as soon as it's ready, no waiting for a spinner to finish. Swipe up for the full breakdown: exact opening line, not just the family name, and the moments Stockfish and Maia disagreed on laid out move by move. It's one continuous thread, not a separate summary screen and a separate board screen.
What's the difference between a game review and a coach diagnosis?
A game review is the analysis itself — the board, the evaluation timeline, and the moments Stockfish and Maia disagreed on. That runs on your phone, costs nothing to run, and is unlimited on every tier, including free. A coach diagnosis is the coach reading that analysis and telling you what it means for you specifically, in your own coaching thread. That's the part that's metered: free includes 5 diagnoses a month, each with 5 follow-up questions.
Can I choose a coaching style?
Yes. Two coaches are live today: EloCoach, who reads each game as a battle and finds the move that decided it, and Apollo, who coaches through the principles that apply in any position. You can switch between them any time. More styles — from patient and encouraging to tough love and opening specialists — are coming with the coach network.
Is EloCoach free to use?
Yes. The free tier includes 5 coach diagnoses a month, each with 5 follow-up questions, and no credit card is required. Analyzing your games is unlimited and always will be. Paid tiers, which add more diagnoses and deeper follow-up conversations, arrive after public launch — beta users get first access and the best rates.
What platforms is EloCoach available on?
EloCoach is available now on Android, with iOS coming soon.
Is my game data and account information private?
Yes. EloCoach only stores the account, game, and conversation data needed to coach you, and acts as data controller under GDPR. See our Privacy Policy for full details on what's collected and why.
