One library for the books you read and the books you listen to: Chaptarr manages audiobooks and eBooks side by side, so the same title can live on your server as a chaptered M4B and an EPUB without two separate apps fighting over it. It knows the difference between editions and narrators, which means a dramatized production, an unabridged reading, and the print text can coexist as first-class versions of one work. Multi-part releases and multi-file recordings are handled as single books, and MP3 audiobooks can be converted into one chaptered M4B with chapters preserved or inserted where they are missing. Separate root folders keep audiobooks and eBooks apart, or place eBooks alongside their audio twins; either way, matching uses file tags, folder names, and release metadata to attach files to the right book automatically. Series are organized for you, metadata profiles control which languages belong in your library, and flexible renaming tokens produce filenames that read the same way a human would shelve them. Custom quality profiles per library drive automatic upgrades when a better release appears, and the standard download clients and indexer integrations from the *arr family plug straight in.
