Chess

Play chess on your Mac and get real-time coaching. Lumini sees your board and explains moves, strategy, and tactics.

Learn chess with Lumini watching your board

You're playing chess on chess.com, Lichess, or the Chess app on your Mac. You make a move. You're not sure if it was good. You wonder what your opponent might do next. Normally, you'd open a browser, find an engine, copy the position, analyze it, and come back — breaking your concentration completely.

With Lumini, you don't leave the board. Hold Ctrl+Option and ask: "Was that a good move?" or "What's my best move here?" Lumini sees your exact board position — the pieces, the colors, the clock if visible — and answers in plain English. No engine window. No analysis board. No tab switching.

How Tutor mode works for chess

Toggle on Tutor mode while playing. After you make a move and pause for a moment, Lumini will speak up. It might say: "You just moved your knight to f3 — that develops a piece and controls the center. Your opponent will probably respond with d5. Consider developing your bishop next." Lumini points at the squares it's talking about.

This is fundamentally different from a chess engine. An engine gives you a number (+0.3) and a list of computer moves. Lumini explains *why* a move is good or bad in human terms — development, center control, king safety, pawn structure. It's a chess coach, not a calculator.

What Lumini can see on your chess board

Lumini works with any chess interface on your Mac. It sees the board as an image and identifies positions. This works on: - **chess.com** — Live games, puzzles, lessons - **Lichess.org** — Open-source chess platform - **Chess app** — The built-in macOS Chess app - **Any chess PDF or webpage** — Analysis of positions in books or articles

Real coaching examples

  • **Opening help:** "I just played e4 and my opponent played the Sicilian. What should I do?" Lumini explains the Open Sicilian, the Alapin, and the Closed Sicilian — and points at the relevant squares.
  • **Tactics training:** You're looking at a tactics puzzle. "I think the answer is Bxf7+ but I'm not sure." Lumini sees the position, analyzes the sacrifice, and walks through the follow-up.
  • **Endgame guidance:** "How do I convert this rook endgame?" Lumini sees your king, rook, and pawns and explains the Lucena or Philidor position you're in.
  • **Post-game review:** "Analyze this game for me." Lumini sees the final position and your move history on screen, and gives a human-readable breakdown of key moments.

Lumini automates your chess workflow

Lumini can handle the administrative side of chess study: - "Create a note with the key lessons from this game" - "Search the web for Sicilian Dragon theory" - "Remind me to do tactics training at 7pm" - "Add Chess Club to my calendar for Thursday"

All hands-free while you stay at the board.
