ShelfKept started because someone needed it. After years of trying to keep a serious audiobook and music collection organized with tools built for something else — generic taggers built for pop singles, media managers that didn't understand series, scripts that broke on the first multi-disc edition — the answer kept being the same: there isn't a tool for this. Build one.
The tool you'd want for a library like that doesn't care about being clever. It cares about being correct. It understands that The Dark Tower is a series with seven entries plus a prequel, that The Gunslinger has been published in two editions, and that the track numbers on disc two should run 8 through 14 rather than restart at 1. It knows what an audiobook is. It knows what classical music is. It treats your files with the care you'd treat them yourself.
That's all ShelfKept is. A tool that treats your library the way you do.
“The best tool is the one that does exactly what you would have done, only faster.”
