Song Cage: Capture Song Ideas

Every songwriter knows the feeling. A melody shows up in the car, a line lands in the shower, a chord change clicks at 2am. Then it's gone.

Song Cage is a songwriting notebook built to catch those ideas the second they hit, so you never lose another one.

CAPTURE ANYTHING, FAST
• Voice memos: sing or hum a melody and save it instantly, with a live waveform.
• Lyrics: a focused lyric pad with a rhyme finder, slant rhymes, and synonyms for when a line won't come.
• Chords: add chords right above your words. Song Cage suggests ones that fit, sorted into in-key, borrowed, and secondary-dominant, then explains each pick: its role in the key, how it voice-leads to the chords around it, and the notes they share.
• Idea inbox: every fragment lands in one place, so nothing slips through the cracks.

NO AI. JUST YOUR IDEAS.
Song Cage will never write your lyrics or melodies for you. There is no AI here, only fast tools that stay out of the way and keep what you made yours.

FINISH ON THE BIG SCREEN
What you capture on your phone syncs to app.songcage.com. Open it on a computer and turn a rough sketch into a finished song, with a full timeline, melody detection from your voice memos, chord suggestions, and PDF and MIDI export.
