Small utilities, all of them local to your browser — nothing here uploads anything anywhere.
More band and jam tools are planned for after launch — a call-sheet builder is first in line, for the moment in a jam when somebody asks what we haven't played yet and nobody can remember.
Anything that turns up here will follow the same rule as the rest of the site: it has to be about the band rather than about an instrument. Tuners, fretboard charts and capo calculators already exist, properly, on the sister sites, and a worse copy of one is not a tool — it is a detour.
