Building a solid opening repertoire is the first step to chess mastery. Instead of memorizing moves blindly, create your own database of favorite lines.

The ChessFlow Repertoire Builder allows you to play out moves on the board, save them with custom names, and recall them instantly. Your openings are stored locally in your browser, so they are safe even if you close the tab.

Features:

• Interactive Board: Play moves naturally to build your line.
• Save & Load: Store your favorite openings and load them with one click.
• PGN Export: Automatically generates the PGN string for your moves.

How to Use

1. Move: Play out your opening moves on the board.
2. Name: Enter a name for your variation (e.g., "Sicilian Dragon").
3. Save: Click "Save Line" to store it in your browser.

Your repertoire is saved locally, so you can come back anytime to review your lines.
