With a few simple clicks, you set it up on your Mac or Linux machine, and everything installs automatically without any hassle.

3
🎵 Paste a song link

You pick your favorite YouTube video, optionally choose which instrument tracks to focus on, and hit process to start the magic.

You see a fun progress bar as it downloads the song, analyzes the beat and key, and splits it into clean individual stems right before your eyes.

5
🎛️ Mix like in a studio

A cool mixer appears with volume sliders, mute buttons, solo tracks, zooming waveforms, looping sections, and live meters that dance to the beat.

6
🔄 Play, tweak, and loop

You play the full song or isolated parts, adjust levels, zoom in on waveforms, set loops for practice, and compare stems to the original.

AI-Generated Review

What is stemdeck?

Stemdeck lets you paste a YouTube URL and extracts AI-powered audio stems—vocals, drums, bass, guitar, piano, other—using Demucs for local processing on your machine. It delivers a DAW-style interactive interface with multitrack waveforms, volume faders, mute/solo, looping, VU meters, and downloads for custom mixes or individual tracks, plus song analysis like BPM, key, and LUFS. Built in Python with FastAPI backend and vanilla JS frontend, it's a single process serving API and static files, running locally with no accounts or uploads.

Why is it gaining traction?

It stands out as a free, private steam deck alternative to cloud tools like Moises or LALAL.AI—no subscriptions, quotas, or data leaks, with GPU acceleration on CUDA/MPS for 3-5x faster stems than CPU. The hook is the polished DAW interface: zoomable aligned waveforms, live mixing, "original" complement track for A/B, and cancellable jobs, all in a responsive web app that feels like a lightweight creative audio workstation. Setup is dead simple via `./run.sh start` after one-shot deps install.

Who should use this?

Musicians practicing transcription, producers remixing tracks, or hobbyists isolating bass/guitar/drums for creative workflows. Guitarists tweaking riffs, drummers studying grooves, or anyone needing quick stems without cloud dependency—runs fine on a steam deck oled or refurbished setup as a portable extraction station.

Verdict

Grab it for personal audio stem extraction; 262 stars and solid README make it approachable, though 1.0% credibility signals hobby maturity with no tests in CI. Self-host via Docker or native for offline practice—beats paid apps if you skip extras like pitch shift.
