Frequently Asked Questions
What is a credit?
A credit refers to the ability to click on any of the Decode buttons. 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.

- It takes only 15-25 seconds to complete the process
