Chordz is a simple tool designed for practicing songs with chord guidance. It provides clean, beginner-friendly chord sheets that help musicians play songs confidently by eliminating the guesswork from chord transitions.

The tool analyzes uploaded audio files to instantly detect the key of the track. It features a smart ring timer that shows exactly how long to hold the current chord, with visual cues indicating when to prepare and when to 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 having users upload their audio files, after which it automatically analyzes the track to detect the key. The circular timer fills up visually to indicate timing, with an empty ring meaning prepare and a full ring meaning play. This visual approach helps musicians anticipate chord changes accurately.

The main benefit is that users can play any song with confidence, knowing exactly when chord changes are coming. The tool eliminates guessing and provides clear timing cues that help musicians stay in rhythm and play accurately.

Chordz appears to be targeted at musicians, particularly beginners who need guidance with chord transitions and timing when learning new songs.
