We read every Udio prompt guide so you don't have to.

What Udio actually rewards

We pulled this from Udio's official guidance and what works in production. The short version:

• →Use detailed but layered prompts.
• →Restate genre/mood multiple ways (50% rule).
• →Use quality tags ('clean production, balanced mix, tight low-end').
• →Crop+extend with DIFFERENT prompts per section.
• →Use 'Music to Prompt' tools to reverse-engineer reference tracks.

Common mistakes we fix automatically

• Avoid
  Don't expect long single prompts to control entire song structure — use crop-and-extend.
• Avoid
  Don't combine conflicting genre tags.

Frequently asked questions

Which versions of Udio does this support?

We support v1.0, v1.5. We apply the prompt patterns Udio recommends for each, so the rewrite is tuned to the version you're using.

Is my prompt stored or used for training?

No. Prompts are sent to the rewriter, scored, returned, and discarded. We don't train on them and we don't keep them around.

Do I need to know prompt engineering to use this?

Nope. That's the point. Paste what you have, click Rewrite, get back a version that follows Udio's official guidance.

What makes this different from Udio's own "improve prompt" feature?

Built-in optimizers use the model's own preferences. Ours is built on Udio's official documentation and patterns that consistently produce better results in production. We keep rewrites inside the length window Udio responds best to.
