The Problem

Stop Guessing Why You Lost

Every player hits a ceiling. Usually it’s not lack of talent — it’s lack of honest, clear feedback.

Repeating Mistakes

You blunder the same tactic in game after game — but without knowing why you missed it, you'll keep missing it.

Missed Opportunities

The winning move was right there. You didn't see it. The engine shows you '-3.2' but never explains what you overlooked.

Locked Behind Paywalls

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

Three Steps to Clarity

1

Step 01

Import Your Game

Paste a PGN, enter a game URL from Chess.com or Lichess, or upload a file. Any format works.

2

Step 02

Get Instant Analysis

Stockfish 18 analyses every move at depth 22+. ChessPilot translates the results into plain English coaching.

3

Step 03

Improve Your Play

Understand your patterns, track your progress, and train the exact weaknesses your games reveal.

See the Difference

Engine Output vs. Real Coaching

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.

Clear explanation. Actionable next step. That’s coaching.

What Players Say

Trusted by Improving Players

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.

AK

I couldn't justify paying for Chessable or a coach. ChessPilot gives me the same depth of feedback for free. It's genuinely remarkable.

SB
Sana B.
1150 Elo

The before/after comparison with a plain-English coaching note next to each blunder is exactly what I needed. Super clean interface too.

MR
Marcus R.
1680 Elo

Used to paste my games into Lichess, stare at the eval bar and learn nothing. ChessPilot actually explains the plan behind each move.

EP
Elena P.
980 Elo

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.

TD

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.

YC
Yuki C.
1340 Elo

No account, no paywall, no excuses. I shared it with my club and six people jumped in that same day. It just works.

NF

I'm a casual player. Chess.com's analysis confused me. ChessPilot speaks to me like a patient coach. I actually look forward to reviewing my losses now.
