Chariot - AI Chess Analysis

What it does

A common practice in chess is to analyze your games. This helps you learn from your mistakes, but also understand the logic behind strong moves. The app takes a standard chess game format, called a PGN, which records every move of a player's game. It then analyzes every move of the game using a computer chess engine, and assigns a rating to each move (good, bad, etc.).

This is a very standard approach to learning from your games, but it can be difficult, especially for beginner/intermediate players, to interpret an engine score and translate it into an actionable lesson. Gemini is used to help explain moves like a coach would for their students. This is done by supplying Gemini with a prompt of an image of the position, the moves that lead to this position, the engine analysis, and other contextual information.

In addition, there is a feature that allows you to play against Gemini. Because Gemini tends to hallucinate illegal moves, Gemini does not freely pick the moves with no context. It is fed the moves that have been played up to this point, and then is given a list of moves to select from an engine designed to play like a human player. As it plays moves it also engages in playful banter.
