Works with your rekordbox library
Cuetto helps you listen, tag and clean up your library one swipe at a time. At the gig, the right track is three taps away. You stay the selector.
Nothing changes until you hit Apply. Automatic backup before every change.
I'm Nick. I play afro and melodic house.
Every week I buy more music than I can really listen to.
Saturday, 1:40 am. The room is ready for something special.
I know the perfect track is in my library. I just can't find it in time.
So I play the safe one. Again.
So I built something that picked tracks for me.
It matched BPM and key. It couldn't hear the marimba, the vocal that cracks, the feeling in the room.
My sets stopped feeling like mine.
So I built the opposite.
Cuetto suggests. You decide.
Same club. Same moment.
Free to start. Pro from €3.25/month, billed yearly.
A note from Nick
Anyone can mix now. Sync, key detection and auto cues made the technical part easy. What still makes a DJ is what you play next, and why.
One of the biggest names in house music calls his own library a maze. Another says DJing has gotten far too easy. I know both feelings.
Crowds want this week's remix and move on fast. Every week my library grew faster than I could listen to it. So I spent months building an algorithm that picked tracks for me. It worked, technically. And my sets stopped feeling like mine.
So I built Cuetto the other way round. It takes the chores. Every musical decision stays with you.

What gets in the way
Three things kept getting in my way. Maybe you know them too.
You know the track is in there. You scroll, the moment passes, you play the safe one.
With Cuetto
Tag tracks in your own words. At the gig, filter by those tags right on the player, and thousands of tracks become a short list.
Over 100,000 new tracks reach streaming services every day.
Luminate, 2025
New music lands every week. Listening to all of it properly takes longer than you have.
With Cuetto
One track at a time: listen, swipe, tag. On the Mac, or on your iPhone and iPad on the couch or the train.
Up to 100 tracks an hour.
Real tagging: listening through each track, 4 tag categories, rating and colour. Not just swiping.
Duplicates, missing artwork, genres that mean nothing. And you don't dare touch it, because your cues and playlists took years.
With Cuetto
Library Health shows what's missing and helps you fix it. Every change waits in a list until you hit Apply.
Backup before every change, one click to undo.
On every plan.
Keep your workflow
Cuetto writes to the library you already use, only when you hit Apply. Then export or sync your USB sticks the way you always do.
Your playlists, cues, folders and settings stay untouched.
Safe by design
Your edits wait in a list you can review. Your DJ software must be closed, so only one app writes at a time.
Cuetto saves a copy of your library right before every change.
Changed your mind? Roll back a whole apply in one step.
No uploads of your audio or your library. Tag suggestions are learned on your Mac.
Honest about AI
Suggested tags
Learned on your Mac from your own tagging. Each suggestion waits for your yes.
Duplicates
Found for you, so you can clean them up in one go.
Metadata and artwork
Artwork, label and year looked up online. Written only when you hit Apply.
In the lab
Track suggestions from your own library while you plan a set. No release date yet.
What you play next.
Not the order, not the moment, not the track that makes the room go up. That part is you. It’s why people come to hear you play.
Cuetto suggests. You decide.
Your week
New music won't slow down. So don't face a mountain once a year. Make it a habit: a little listening every week, and your library keeps up with the flood.
Based on my own pace: up to 100 tracks an hour in focused stretches. Real tagging: listening through each track, 4 tag categories, rating and colour. Not just swiping. Your pace will be different.

I’m looking for DJs who want to try Cuetto on their own library and tell me honestly what they think. Leave your email, confirm it, and I’ll send you an invite.

Cuetto is a Mac app for tagging your DJ library one track at a time. You swipe through your tracks, listen, and add your own tags, rating, color, genre and playlists on a single card.
Everything you change is collected first. When you are ready, Cuetto writes it to your library in one step, with a backup made just before.
Cuetto works with rekordbox 6 and rekordbox 7 libraries on macOS. Older libraries from rekordbox 5 and earlier are not supported.
If an update of your DJ software changes the library format, Cuetto tells you right away. You can keep tagging, and applying works again once you update Cuetto.
rekordbox is a trademark of AlphaTheta Corporation. Cuetto is not affiliated with AlphaTheta.
Cuetto is built to make that very unlikely. Nothing changes in your library while you tag. Your changes wait in a list you can review, and they are only written when you click Apply.
Before every apply, Cuetto makes an automatic backup of your library. Cuetto also checks for conflicts, so it never overwrites something that changed in the meantime. If you don't like the result, undo the whole apply with one click.
Yes. The free companion app for iPhone and iPad connects to Cuetto on your Mac. At home on the same Wi-Fi this works on every plan. From anywhere else, you need Remote Access, which is part of Pro.
The companion is not a standalone app. Your Mac needs to be on with Cuetto running.
Cuetto takes the chores. Every musical decision stays with you.
