About ChessGrandMonkey

🐒♟️

ChessGrandMonkey started with a simple idea: chess data should be fun, free, and easy to understand. No paywalls, no confusing jargon, no sign-up required. Just useful tools and honest analysis for players who want to get better.

What we do

We build chess tools that thousands of players use every month. Our ELO converter helps you understand what your Chess.com rating means on Lichess or FIDE. Our percentile calculator shows where you stand compared to everyone else. And our IQ calculator? That one is just for fun - don't take it too seriously.

We also dig into chess ratings so you can understand what any rating actually means. Whether you are a 600 just starting out or an 1800 trying to crack 2000, we have guides that break it all down.

On top of that, we cover major chess tournaments and news, from the Candidates to the World Championship. No clickbait, no filler - just the stuff that matters.

Why a monkey?

Because chess is already full of serious-looking websites with dark themes and stock photos of old men staring at boards. We think chess can be serious and fun at the same time. The monkey reminds us (and you) not to take things too seriously. Blunder a queen? Even grandmasters do that sometimes. Dust yourself off and play the next game.

The goal

We want to be the most helpful chess companion on the internet. Simple tools that work, honest analysis, and a friendly vibe. That's it. No hidden agenda, no subscription traps. Just a bunch of chess-loving monkeys trying to make the game more accessible for everyone.
