Meet Ziuk, Your Personal AI Chess Assistant
Chess engines can tell you that a move was a mistake. Understanding why is a different story.
Today, we’re introducing Ziuk, Chessify’s new AI chess assistant.
You can open a game or position and simply ask what you want to know:
- “Why was this a mistake?”
- “What is White’s plan here?”
- “Can Black still hold?”
- “Analyze this game for me.”
And you can ask in your own language.
But Ziuk isn’t just an AI that knows about chess. It can use the tools already inside Chessify to find the answer.
It can work with the position on your board, use Chessify’s cloud Stockfish and Lc0 engines, search our game databases, and bring that information together into an explanation you can actually understand.
So instead of running an engine, checking the evaluation, looking through lines, and then trying to figure out what all of it means, you can just ask.
More Than Engine Evaluation
Suppose the engine suddenly changes from +0.3 to −1.2.
Normally, you know something went wrong. You can follow the engine line and see the better move, but that still doesn’t necessarily tell you what you misunderstood about the position.
It can look at the position and the analysis behind it and explain the idea: maybe you weakened an important square, missed a tactical resource, traded the wrong piece, or chose the wrong plan entirely.
And because it’s a conversation, you don’t have to stop at the first answer.
Ask why. Ask what you should have noticed. Ask what the opponent is threatening. Ask it to explain the position more simply.
Chess Analysis in Your Own Language
Chess has always had a language problem that engines couldn’t solve.
The evaluation +0.8 looks the same whether you speak English, Armenian, Spanish, French, or Japanese. The explanation doesn’t.
With Ziuk, you can ask your question in the language you actually think in and get the explanation in that language too.
There are no special commands to learn. Just ask the question the way you would ask a coach.
It Can Work With Your Chessify Workspace
Ziuk doesn’t live in an empty chat window.
It can work with the position on your board and use Chessify’s chess tools when it needs them — including our cloud engines and game databases.
You don’t have to decide which engine to run, which lines to check, or where to search first.
You ask the chess question; Ziuk figures out which tools it needs to answer it.
And if you want to analyze one of your own games, you don’t need to set anything up manually. Enter your Chess.com or Lichess username, and we’ll fetch your recent games so you can choose one and start analyzing it with Ziuk.
Start for Free
You don’t need a paid plan to try Ziuk.
Every Chessify account gets 12 free AI coins every day. A typical question uses around 5–8 coins, so that’s usually enough to ask Ziuk a question or two each day.
A full game analysis typically uses around 30–60 coins, depending on the game.
Paid plans come with larger daily AI allowances:
| Plan | Free AI coins / day |
|---|---|
| Free | 12 |
| Amateur | 50 |
| Master | 250 |
| GM | 1,000 |
If you need more, you can also add coins separately from here. 100 coins cost $1, with bonus coins on larger top-ups.
Let Ziuk Analyze One of Your Games
The easiest way to see what Ziuk can do is to give it one of your own games.
Enter your Chess.com or Lichess username, choose one of your recent games, and ask Ziuk to analyze the full game.
It will go through what happened, find the important moments, and explain where things started to go wrong — and what you could have done differently.
Then keep asking.
- Why was this move a mistake?
- What should I have noticed here?
- What was the right plan?
That’s where Ziuk becomes more useful than a one-time game review: the analysis can turn into a conversation about your game.
