Frequently Asked Questions

A Decode is an explanation in intuitive language, generated by our unique artificial intelligence algorithms. With a decode you can do two things:

  1. Decode Game: Analyze an entire game and receive explanations for the recommended moves of a chess engine (Stockfish). This only takes about 60 seconds!
  2. Decode Deep: Analyze a chess position in-depth to receive a 360° analysis of threats, attacking plans, concepts, piece functionality, good moves, and more.

We usually recommend to use Decode Game and then lock in on 2-3 key positions and click on Deep Decode.

We currently support PGN and FEN formats.

Yes, we will save any game you upload, and you’ll be able to tag or delete them. Most importantly – we will save every Decode you perform, be it a single position or an entire game.

We do not have an app that you can download yet, but DecodeChess is mobile-responsive. This means that you can access it via your smartphone, simply with less analysis features due to the size of the screen.

Annual and monthly subscriptions include  a 30-day and a 7-day money back guarantee, respectively.

Pay-as-you-go plans do not include a money-back guarantee.

DecodeChess Helps Players Improve at Chess

“DecodeChess helps me go through all of my games and assess my strengths and weaknesses. With a chess coach, I might be able to analyze one or two games per week. With your product, I can analyze many times more. In that way, the technology you’ve invented is helping make me a better chess player.”

“I have been playing the DecodeChess computer and using the Decode process to work through the various main lines. The running graph that is displayed is excellent as well. Whole setup is working really well and I am learning a lot, easily the best chess education around.”

“I am really engaged, and like the way it describes everything in human language and is easy to understand. I fully studied the Danish Gambit, and use it as my main opening now.”

“I enjoy the insights Decode Chess supplies, especially on the complex mid-game positions. Although I’m not a very strong player (yet) I appreciate the depth and explanations that Decode Chess provides. I highly recommend this app.”

I love the range and depth of the analysis provided after a “decode.” This is the most helpful feedback I have ever found.

Thanks again for making DecodeChess in the first place. It’s like those wonderful books I learned so much from where the reasons behind each move were explained, getting ideas pointed out to me like a chess coach does.
