Over the past few days, my child has been participating in several chess tournaments, which inspired me to make a major update to https://chess-notation.com. The key improvements include:

HTTPS & SSL Encryption: Now using HTTPS with SSL to ensure user data is securely protected.

Google Sign-In & Cloud Storage: Users can now sign in with Google. Uploaded notation data is securely stored on the server, and users have the option to delete their data at any time.

Side-by-Side Comparison Tool: Added a feature to compare uploaded notation images with the notation results generated by the vLLM large language model.

AI-Powered Auto-Correction:

The first correction mode uses a step-by-step validation process with a chess engine. It helps users quickly fix the first invalid move and automatically validates the rest of the game based on the fix.

The second mode is fully AI-driven. It attempts to repair the entire game in one click by minimizing the number of changes and invalid moves using a custom cost function. In our experience so far, the step-by-step interactive mode performs best, but both correction options are available on the platform.

Major UI and UX Improvements: The user interface and interaction flow have been significantly enhanced for a better experience, especially optimized for mobile devices.
