ABOUT

Built in the gap between two crafts.

CueDJ is made by Sindro LLC, a product studio built around one conviction: that mixing is an engineering problem and a musical one at the same time. It comes out of years spent on both sides of the booth (shipping software by day, playing house records by night) and the frustration of those two skills never being in the same room.

01the itch

DJ software treats the library as a list. But a library is a graph: every track connected to every other by key, energy, and phrase. CueDJ is what happens when you build for the graph.

The first version was a weekend script that answered one question: "what mixes out of this?" Then the question got greedier: show me the whole set. Then greedier still: hear what I'm playing and answer in real time. Three modes later, that script is CueDJ.

There's no growth team here, no engagement metrics, no roadmap-by-committee. Just the tool, the people using it, and an inbox that gets read.

02operating principles

Four rules this product won't break.

LOCAL-FIRST, ALWAYS

Your files stay your files

Analysis, fingerprinting, mixing: all on your machine. There is no cloud in the audio path, and there never will be. The privacy policy is short because there's little to disclose.

NO SUBSCRIPTION

Instruments aren't rentals

One payment. Nothing auto-renews, nothing to cancel, nothing turns off if you stop paying. Because you already paid.

NO FAKE PROOF

Demos over testimonials

No invented reviews, no inflated counts, no "as seen in." The simulator on the homepage is real engine output. When real users say real things, you'll see them: attributed and verifiable.

HONEST LIMITS

The roadmap is not the product

If something isn't built yet, the site says so: mic detection scope, hardware support, export formats. You should know exactly what your $79 buys today.

That's the whole story. The rest is in the build.
