Questions
How does it work?
Three models run on your device. One splits the song into its instruments, one finds the beat, and Fretformer, Autochart's own model, writes the notes.
How good is it?
Expert is the strongest. Lower difficulties are rougher for now. Every take comes out different, so try a few.
What can it chart?
Five-fret lead guitar. No bass, drums or vocals yet.
Can I share my charts?
Play them, stream them, send them to friends. Please keep them off community chart sites.
What do I need?
Any recent computer works. 16 GB of memory is best; with 8 GB, close other apps and tabs first. A GPU makes it a lot faster. The model download is about 950 MB (500 MB in the browser).
Does it upload my music?
No. Everything runs on your device, in the app and in the browser. Privacy
