algRTHM
A Spotify playlist automation app. You schedule little "algorithms" that keep your playlists fresh and in order, and somehow it still feels like you made them.
Overview
algRTHM is for people who take playlists a little too seriously. (Hi. That's me.) Most weeks I'd catch myself pruning tracks, reordering, second-guessing the flow, then doing it all again seven days later. So I built something to handle the boring parts.
You set up scheduled "algorithms," small rules that rotate songs, surface fresh finds, and protect the energy you worked so hard to get right. It grew straight out of something I wrote, the art of playlisting. The whole bet is simple. A playlist made by hand is worth something an algorithm can't fake, so the tool should make the curator better instead of replacing them.
Where it's at
We're in private beta, sponsored by Crate Hackers, waiting on full Spotify API approval. Still plenty left to build:
- Scheduled algorithms, with limits per tier
- Insight dashboards: growth over time, how long a track has stuck around, where listeners actually found you
- A structure analyzer that graphs a playlist's audio features from first song to last
- A proper editor, plus curation teams
Stack
Nuxt up front, the Spotify Web API underneath, scheduling that runs server-side, and a free tier that grows into pro whenever you need it to.
