Tag, check and repair your music library.
TagRitual makes one pass over your tracks and answers five things: what genre they are, which files have audio problems, what metadata is missing, which rekordbox grids are wrong, and what in your collection is worth playing again. Everything runs on your Mac, and nothing changes until you approve it.

What it does
Genre and vibe tags
Ranked tags per track, drawn from a fixed vocabulary of a few hundred rather than invented per file. Both the audio and the metadata are weighed, several tags can apply at once, and incompatible combinations are ruled out. Approved tags are written to the Grouping field — the one Rekordbox, Serato and Apple Music all read.
Audio problems
Every track is measured for level, and the ones that are too quiet, too hot or genuinely clipped become a filterable work queue rather than a surprise mid-set. Each carries a concrete action — cut 2.4 dB, needs limiting, or re-master — and a lone peak touching full scale is not mistaken for clipping. TagRitual diagnoses without ever modifying your audio.
Missing metadata and artwork
Finds tracks with no embedded cover art and restores it, preferring a backup you already have before looking anything up. BPM, key, label and year are detected or filled in from Discogs, MusicBrainz and iTunes — each one optional, and each one leaving existing values alone unless you say otherwise.
rekordbox grids
Reads your collection or a USB export and measures every cue against the grid it was set on, so the tracks whose beatgrid drifted are listed rather than discovered mid-set. An audio cross-check confirms whether the grid matches the music itself. Fixes go through the XML, so a Sync Manager rebuild doesn't undo them.
Music worth playing
Reranks your own library against what you're into now — the tracks you own and forgot — and suggests artists you don't own yet. For anything you have a poor copy of, it looks for a better one: on this Mac, in a collection you already bought, or in a store. Each candidate shows its codec and bitrate, so you can see whether it's actually an upgrade.
How it works
Point it at your music
A folder, an Apple Music playlist, an XML playlist, or a drag and drop. TagRitual reads the metadata already in each file and analyses the audio itself.
One pass, five answers
A track is decoded once. Out of that come its tags, its tempo and key, its level measurement and its format facts — so the second thing you ask for costs almost nothing. Results are cached per file and reused until the file changes.
You decide what changes
Nothing is written until you approve it. Tags go into the Grouping field in place, with a backup taken first. Grid fixes are recorded so they can be re-applied or undone. Audio is never modified.

Also
Formats
MP3, M4A/ALAC, FLAC, AIFF and WAV. Tags are written to the native field for each format, with ExifTool as a fallback.
Bulk runs
The same app runs headless from the command line for a whole library overnight, at the level of approval you choose.
Audio player
Playback and a waveform in the review window, drawn from the same level measurement — a clipped section is visible before you play it.
It learns
Tags you keep and tags you remove feed back into later scans, and you can write your own artist, label and tempo rules.
CSV export
Every scored track with its tags, scores and reasoning, for reviewing a large batch outside the app.
Reversible writes
A backup before each file is touched, atomic replacement, and original dates preserved. Only the fields you asked for are changed.
Questions
Does my music leave my computer?
No. Analysis and scoring run on your Mac using models built into macOS. The only network traffic is license activation, once, plus the optional metadata and Discover lookups — which can each be switched off and send nothing but artist and title text.
Will it change my audio files?
It never modifies audio. Loudness and clipping are reported with a recommended action; making that change is a job for an audio editor, or for finding a better copy. Metadata writes touch only the fields you enabled, after taking a backup.
Will it overwrite tags I've already set?
Only where you tell it to. TagRitual writes the Grouping field and leaves every other field alone unless you enable it, and it can skip anything that already has a Grouping value.
How accurate are the tags?
It is a suggestion tool, and it is wrong sometimes — which is why nothing is written without approval and every suggestion shows its reasoning. On familiar material most tracks need no correction; unusual or sparsely-tagged ones need more.
Do I need to be online?
Once, to activate. After that TagRitual holds a signed token valid for 90 days that renews itself when you happen to be online. It's used on laptops at gigs with no signal, so nothing in the licensing interrupts a set.
Is it a subscription?
No. One purchase. A license can be moved between Macs by deactivating one and activating the other.
Pricing
One purchase, not a subscription. The first 100 tracks you write tags to are free and need no account. After that, scanning, scoring, review, the grid check, playback and CSV export continue to work; writing to files needs a license.
