Chordz is a simple tool designed for practicing songs with chord guidance. It provides musicians with clean, beginner-friendly chord sheets that include pre-timing cues to help users play along with confidence.

The tool features audio file upload capability with automatic key detection that analyzes tracks instantly. It includes a smart ring timer that shows exactly how long to hold the current chord, with visual indicators showing when the ring is empty (prepare) and when it's full (play). The system uses prepare-to-play logic that displays 'PREPARE' ahead of time and flashes 'PLAY NOW' exactly when you need to strike the chord.

Chordz works by allowing users to upload their audio files, after which it automatically detects the key of the track. The interface then displays chord sheets with a circular timer that fills up to indicate timing, helping users transition between chords smoothly.

The main benefit is that it eliminates guessing about chord changes and timing, making it easier for musicians to practice songs confidently. It provides clear visual cues that help users know exactly when to prepare for the next chord and when to play it.

This tool appears to be targeted at musicians, particularly beginners who need assistance with chord transitions and timing while practicing songs.
