After the trial expires, you must register the software to continue using it. You can purchase an official license directly from the Chord Pickout website System Requirements:

Drag and drop music files to start the process.
If you need the full version, I recommend purchasing a legitimate license from the official website or an authorized reseller. For a free or low-cost alternative, you might explore open-source audio-to-MIDI or chord detection tools (e.g., Sonic Visualiser with plugins, or tools like Chordify’s free tier).
