Those four chords are the key’s three main chords (I, IV, V) plus its relative minor (vi), and they share so many notes that almost any order flows. That’s why thousands of different melodies fit over them. What changes the feel is the chord you start on and the rhythm.

What it does not do
It does not use AI or write the song: it suggests chords from harmony rules, and the melody and lyrics are yours.
It does not make audio to release: the sound is a simple guide for trying ideas.
It does not analyse existing songs or tell you which hit uses a progression: chords have no owner and repeat across thousands of songs.
It saves nothing and sends your choices to no server: everything happens in your browser.
