What You Actually Do With It
Three things, over and over, until the song is in your hands.
Learn it from the record,
not a stranger's tab
A tab is somebody's best guess, and half of them are wrong. StemScribe pulls the
song into its parts so you can solo the guitar and hear exactly what's played —
every voicing, every hammer-on.
The chord chart is read off that isolated guitar, so it names what the guitarist
fingered — not the C/G a walking bassline renamed underneath an open C. And
every chord is one click from playing on its own, so you check it against your ear
before you ever trust it. Want the whole harmony — keys, extensions, the lot?
Full Harmony view is one click away.
▸ Under the hood: six-stem separation + guitar-first chord detection.
FIG_01 // SOLO THE GUITAR · READ ITS CHART · CHECK BY EAR
Practice like you're in the band
Mute the guitar and the rest of the band keeps playing — real drums, real bass, real keys — while you take the part live. Loop the four bars that keep tripping you (snapped to the beat, not to four random seconds) and drop them to half speed without the key going chipmunk. It's the garage, with the actual record as your band.
Loop
Bar-snapped, not seconds. Hold ALT to place freely.
Slow Down
0.5× to 1.5×, key stays put.
Transpose
±12 semitones. E / E♭ / D presets.
Capo
Names the fret that opens up the most shapes.
Click + Count-In
Locked to the detected beat.
Never run out of
things to play over
Out of songs to work on? Describe a backing track — blues shuffle in A, 90 bpm
— and get one. Or import a riff of your own into it and StemScribe builds a full
band around your idea: bass, drums, keys, locked to your feel.
Then mute your part and jam over the band you just made. It's generated on your
machine, then separated and charted like any other song — so it drops straight
into the same practice loop.
▸ Generation powered by Stability AI. Optional 3.49 GB component, downloaded on first use. Generated audio is subject to the Stability AI Community License and the Gemma Terms of Use.

Not sure? Pick "Everything else" — it works on any PC. Both builds do exactly the same thing and produce identical output; the only difference is which maths library is bundled.

Straight Talk
- ▸ Windows will warn on the installer. It is unsigned. Click More info → Run anyway. A SHA-256 checksum is published next to each download so you can verify what you got.
- ▸ It's a big install. 258 MB installs to about 1 GB; the NVIDIA build is 1.7 GB installing to about 4.5 GB. The separation and chord models download on first use. The optional generation component is a further 3.49 GB — the installer asks, it doesn't assume.
- ▸ The chart can be wrong. Separation and chord recognition are statistical. That's why every chord is auditable — solo the stem, click the chord, trust your ear over the chart.
