Tools that do the boring part

Prompt Builder (Style field)

Most weak generations start with an overloaded Style line. The builder gives each control its own slot — genre, instruments, vocal behavior, mood/energy, production space, tempo, song arc, melody — so you can change one thing at a time and keep the wording that worked.

Lyrics text diff

Regenerating with a revised lyric sheet is only useful if you know what changed. The diff treats each line as a unit: unchanged, modified, added or removed — so you can attribute a better result to a specific edit.

Song downloader

Reads a public song page and offers the files behind it: audio in your preferred container, the video render, the cover image and the lyrics text. Filenames follow one pattern so your library stays sortable.

Song inspector

The inspector is a read-only pass over a public song: metadata, the style string broken into its parts, the lyric structure map, and a light audio analysis so you can hear why a mix feels the way it does.

Playlist downloader

Turns a public playlist into a ZIP with deterministic numbering — so a saved collection still makes sense a month later, even after edits upstream.

Profile downloader & creator insights

Looks at a public creator profile as a body of work: how many tracks, which styles recur, average duration, publishing rhythm and style diversity. Useful before a project or a collaboration.

Lyrics structure tag helper

Section tags steer arrangement. The helper inserts the standard set, checks your sheet for unknown or duplicated tags, and keeps the format consistent across versions.

Lyrics tag normalizer

Past sheets drift: [Chorus 2], [主歌], bare Verse: headers. The normalizer maps them back to the tags the model actually understands.

Lyrics duration estimator

Before you generate, estimate how long the sheet will sing at a given pace, per section — so a three-minute target doesn't turn into a six-minute song.

Style string cleaner

Deduplicates repeated tags, strips marketing filler ("amazing", "viral"), fixes separators and reports what was removed and how full your character budget is.

Exclude list builder

What you don't want needs to be as specific as what you want. Pick from common offenders or add your own, then copy one clean list.

Random style generator

A structured dice roll across the pillars. Lock the parts that worked, re-roll the rest, and collect the combinations worth keeping.

Batch link parser

Paste dozens of public links; get one table with parsed identifiers and status, exportable as CSV or JSON for a spreadsheet or a script.

Cover art downloader

Cover images at original resolution or resized to common store and social sizes, in JPEG, PNG or WebP.

Lyrics MV Studio

An in-browser studio: pair a track with timed lyrics, pick a look, preview in real time, and export a shareable lyric video.
