Suno v6 prompt upgrader

Paste a prompt from v4.5 or v5.5. See every habit v6 trips on and what to do instead, and get your Styles and lyrics cleaned up, before you spend a credit.

Suno's field names (Style of Music, Lyrics, Exclude, Title) are read if you kept them. Otherwise everything above the first [Section] tag counts as Styles.

Paste yours on the left, or load the example. Everything runs in your browser: nothing is sent anywhere.

What it checks

The rules, and why each one matters.

Tag lists and weights

Twenty comma tags and (piano:1.3) weights were how older prompts worked. v6 follows sentences that direct each part; weights get read as words.

Negatives and quality words

"No drums" adds drums, and "radio-ready" grades the record instead of directing it. Negatives move to Exclude; grading words go.

Artist names and model tags

Suno blocks artist names and can flag them as copyright. "v4.5" in Styles does nothing. Both are removed; the sound words around them stay.

Styles hidden in the lyrics

[Genre: house] and [BPM: 124] lines were a v3.5 / v4 trick. They move into Styles, where v6 reads them.

Bare tags, repeats and directions

[Verse] with no cue, (x2) shorthand and (whispered) directions that Suno sings as a second voice. Repeats are written out; directions move into the header.

The ending

Old sheets rarely say how the song stops, so v6 fades, loops or cuts off. The full package always ends on an [End | …] cue.

FAQ

Questions people ask.

Why did my old Suno prompt stop working in v6?
v6 retired the older models and reads prompts differently: it follows directed sentences more than tag lists, sings what's in parentheses, and pulls genres toward pop without a clear lead tag. Habits that were harmless in v4.5 now change the song.
Does it keep my own wording?
Yes. The upgrader only removes what v6 misreads. In the full package your cleaned Styles opens the new prompt word for word, with the rest written around it.
Are my prompts sent anywhere?
Not here. The upgrader runs in your browser with code, no AI model. The full package is built only when you ask for it in the studio.
What about the Exclude field?
Older prompts often had no Exclude at all, or put negatives in Styles. Negatives move into Exclude as short category words, kept under ten terms.
Will the converted song sound the same?
No promise: v6 is a different model. Keeping your own words and tempo gets you the closest start, and the package's settings card says which sliders hold it there.
