01 / The thought

Ideas do not need to be finished to be worth keeping.

One clear loop

Sing. Shape. Keep.

Meloisa takes you from a fragile voice note to something you can hear, understand and play—without turning creation into a technical session.

01

Record

Hum, sing or play a short melody, one note at a time. No setup. No blank project.

02

Reimagine

Hear your tuned voice or a piano melody over chords. Change the scale, texture or an individual note. Your Original stays untouched.

03

Keep the spark

Save the Original and your versions in a private library. Come back, compare and export when the idea is ready.

Hear the possibilities

One melody. Make it yours.

See a guided example in the real app: listen, change the scale, switch the sound and edit a note. Start with your own voice, or use the sample when you cannot sing right now.

Sound on for the demo. The video uses Meloisa’s instrumental sample. Full access requires Premium.

Your next musical idea

From spark to something playable.

Every screen protects momentum. Capture first. Make the melody clear. Choose its colour. Then let harmony enter.

Private by design

Keep your ideas to yourself.

Unfinished music can be personal. Meloisa is designed so the creative loop happens locally. Your recordings do not need to be uploaded to become melodies, versions or arrangements.

  • On your device

    Recording, melody analysis and the core transformation loop are designed to run locally.

  • No identity required

    The first product experience is designed without an account or social profile.

  • You choose what leaves

    An idea leaves the private library only when you deliberately export or share it.

Melody first

Same thought. A different musical light.

A Lens reshapes the notes of your melody toward a musical scale before harmony is added. You hear exactly what changed—and the Original is always one tap away.

No theory required. Musical detail is there when you want it, never in the way.

A living library

Never overwrite the spark.

Your first recording becomes the Original. Every Lens and arrangement becomes a new version around it, so an idea can grow without losing where it came from.

Useful answers

Before you record.

Is Meloisa an AI music generator?
No. Meloisa begins with your musical thought. Its engine analyses and reshapes your melody, then creates playable harmonic possibilities around it. The idea remains yours; the product helps you hear it more clearly.
Does my recording get uploaded?
The core musical loop is designed to work on your device, without uploading your recording. If a future optional service changes that, it will be clearly explained and require an intentional choice.
What can I record?
For the first version, Meloisa works best with a short, monophonic idea—roughly 2 to 30 seconds—sung, hummed or played one note at a time.
Do I need to understand scales or chords?
No. Lenses are described by feeling as well as musical name. Notes and chords are there to help you follow and play, not to test your theory.
Can I return to the first recording?
Always. The Original is immutable. New melodies and arrangements become versions rather than replacing the source.
Where can I get Meloisa?
Meloisa is available on the App Store for iPhone. The app works in English and Spanish. Download it to try the guided experience; Premium is required to continue into the full app.
