Frequently Asked Questions
What is a decode?
A Decode is an explanation in intuitive language, generated by our unique artificial intelligence algorithms. With a decode you can do two things:
- Decode Game: Analyze an entire game and receive explanations for the recommended moves of a chess engine (Stockfish). This only takes about 60 seconds!
- 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.
What file formats do you support for uploading my own games?
We currently support PGN and FEN formats.
Are my games saved?
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.
Can I use DecodeChess on a mobile phone?
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.
Is there a money-back guarantee?
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.
