About
Hey, it's Lucas 👋
After Audiobook Converter had been out for a while, customers started reaching out expecting the M4B made from their single long MP3 file to have chapters. Fair enough, honestly. Without chapters, it's basically the same long file in slightly nicer packaging.
At first I thought about squeezing that into Audiobook Converter, but the more I looked at it, the more it felt like a different problem entirely. Converting files is one job. Figuring out where chapters belong is another.
So instead of making Audiobook Converter wear too many hats, I built Chapterize Audiobooks.
