Paste any game and get Stockfish-powered, plain-English feedback on every move — what you missed, why it mattered, and exactly what to play instead.
The Problem
Every player hits a ceiling. Usually it’s not lack of talent — it’s lack of honest, clear feedback.
You blunder the same tactic in game after game — but without knowing why you missed it, you'll keep missing it.
The winning move was right there. You didn't see it. The engine shows you '-3.2' but never explains what you overlooked.
The best coaching tools cost $20/month. You just want to understand one game. You shouldn't need a subscription for that.

ChessPilot is a patient coach, not a cold engine.
It speaks human — so you can focus on learning, not deciphering eval strings.
How It Works
Step 01
Paste a PGN, enter a game URL from Chess.com or Lichess, or upload a file. Any format works.
Step 02
Stockfish 18 analyses every move at depth 22+. ChessPilot translates the results into plain English coaching.
Step 03
Understand your patterns, track your progress, and train the exact weaknesses your games reveal.
See the Difference
The same position. Two very different ways of telling you what happened.

Blunder on move 18
Moving your king to d2 walked right into a discovered attack. Your bishop on c1 was blocking the rook’s defence of d1 — after Kd2, Black’s knight on f3 forks your king and queen.
Better Move
Qh5 — attacks f7, threatens checkmate, keeps all pieces defended.
Focus Area
King safety during open positions. Practice puzzles involving discovered attacks.

What Players Say
“Finally an analysis tool that tells me WHY a move was bad. I've been stuck at 1400 for a year — understanding my mistakes is changing everything.”

“The opening explorer helped me fix a gap in my Ruy Lopez prep in one session. Clear, structured, and free — can't ask for more.”
“Puzzle Rush is addictive. I set a new streak every week. But the analysis is the real gem — I finally stopped playing the same knight blunder.”
“No account, no paywall, no excuses. I shared it with my club and six people jumped in that same day. It just works.”
