About
A second pair of ears for musicians who don't have one
Most musicians learn on their own. Lessons, a producer and studio time cost money, so the honest feedback that helps people improve mostly goes to those who can already pay for it. This app gives that feedback for free, on the recordings people already make: a phone memo is enough.
Who it's for
- Self-taught musicians with no teacher to ask what's working, what's missing, and how they're progressing.
- Teachers and community programmes with more students than hours: a group sees the work members choose to share, and what's there and not there across it.
- Anyone with unreleased music who wants feedback without handing their work to a platform.
What it does
- Reads a recording back in plain words and pictures: key, chords, form, groove, who plays when, energy and mood.
- One track: ideas to try first, built on what it leaves out. Several, or next to a song you admire: what's there in all of them, and what none of them has yet.
- Follows you over time: your style across sessions, and how it changes.
- Works on a phone: record in the browser or send a Voice Memo; keep recordings, tag them, analyse when you choose.
Your music stays yours
- Audio sent for analysis is deleted as soon as it's analysed. Recordings you choose to keep are only playable by you, and deleted with one click.
- Nothing you upload trains any model. The optional AI sees numbers only - never audio, never file names.
- “Find music like this” deliberately points to artists with between 20 and 10,000 listeners, not the names everyone already hears.
How sure it is
Automatic analysis makes mistakes, and we'd rather show you how often than promise it doesn't. Every update runs a self-test on music with known answers (generated tracks, and real recordings whose tempo, key and line-up their musicians confirmed). These are this server's last results:

On real music, expect the key to be right about 70–80% of the time (the usual slip is the relative key: B minor for D major), and the tempo sometimes at half or double what you feel. Chords are simplified, and section letters are a rough map. We say so in every report, and you can correct a result: your corrections count from then on.
Who uses it
Totals only: nothing about who, or what music. Counts under 10 aren't shown, so no one can be picked out.
What it isn't
It isn't a teacher, and it doesn't replace one. It fills the gap where there is no teacher: a quick, honest first listen and a few concrete things to try. The style and instrument models are by the Music Technology Group, Universitat Pompeu Fabra (CC BY-NC-SA 4.0, non-commercial use), which suits a free, educational tool.
