1 TB free audio storage

See the verse, chorus, and drop mapped on a timeline.

Upload a track and ask where the sections are. Scarleta maps the song into its segments and lays them out on a timeline, with the beat and downbeat grid, right in the chat.

How it works

No setup, no plugins. Just ask, and get the file back.

Step 1

Upload your song

Drop an audio file into the Scarleta chat: a full track, a mix, or a rough bounce of your session. Nothing to install.

Step 2

Ask to map the structure

Type it in plain words: "where is the chorus and the drop?" The AI figures out which analysis to run. No settings, no code.

Step 3

See the song's map

Get the song broken into segments: intro, verse, chorus, drop, on a timeline you can actually read, with the beat and downbeat grid, right in the conversation.

Built-in storage

Every result is saved to your library, 1 TB free.

The files you bring and the structure and rhythm map results you get are kept in one place, so you can come back, compare earlier versions, share a link, or ask across everything you’ve stored, whenever you want.

For developers

Map a whole catalog with the API

Building it into an app or running a whole library? Send a batch of files to a structure recipe and let a webhook call you back when each one is done.

  -H "Authorization: Bearer $SCARLETA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "recipe_id": "rec_0001_song_structure",

Frequently asked questions

What do I get back?

The song split into sections: intro, verse, chorus, drop and so on, along with the beat and downbeat grid and the meter. You can see it on a timeline right in the chat, and export the analysis as CSV or JSON to use in your own tools.

How much does it cost?

You pay per second of audio: $0.10 per minute, from prepaid tokens (1 token = 1 second). New accounts start with 300 free tokens, and top-ups begin at $10. No subscription.

Do I need to install anything?

No. Upload a track in the Scarleta chat and ask. It runs right in your browser with nothing to download.

Can I map a lot of songs from my own app?

Yes. Developers can send many files at once through our API and get called back by webhook when every one is done. See the docs to get started.
