Sift

  • iOS app
  • Awaiting App Store launch
  • 2026

A paid iOS app for finding music. An AI curator sifts about 500 candidates down to six tracks for you.

Notes

An AI-driven curator goes through roughly 500 candidate names and sifts them down to six tracks for you.

Each pick is plotted on two independent axes, how well it matches your taste and how obscure it is, and an LLM re-ranker explains every one of them.

There are three parts: a Python backend, the iOS app in SwiftUI, and the site at listensift.com, built with Astro and a Three.js liquid-flow home page. The site has been live since 2 October 2026. The app is waiting on its App Store launch.
