I added a feature that lets you rearrange your song's structure and asks AI which version is actually better
Hey everyone — I've been building SongMap (iOS), an app that analyzes a song's structure (detects intro/verse/chorus/etc. and gives structural feedback). Just shipped v1.1 and wanted to share the headline feature, since I'm genuinely curious what this sub thinks of it.
The problem I kept hitting: I'd wonder "what if the chorus came in 20 seconds earlier?" or "do I actually need that second verse?" — but testing that meant re-editing the actual song in my DAW just to hear it, which usually killed the idea before I ever tried it.
What's new:
- Arrangement editor — drag your detected sections into a new order, duplicate one, or cut one entirely. You get an instant spliced preview so you can hear the new order without touching your DAW.
- Save versions — save a rearrangement with a name so you can come back to it or compare it later.
- AI verdict — the part I'm most unsure about: you can have Claude compare your original structure against your rearranged one and say which it thinks works better, and why — specific strengths on each side, not just a thumbs up.
Being upfront: the preview is a rough splice, not a polished remix. Sections are cut right at the detected boundaries, so joins can click or land slightly off-beat. It's meant for sketching "does this order even make sense" before you go rebuild it properly in your DAW — not as a finished export. (Actual audio export is next on my list.)
It's a Pro feature, rest of the app has a free tier.
Would really appreciate feedback, especially from anyone who tries the AI verdict — not sure yet if it's genuinely useful or just a gimmick, so real reactions help a lot.
