Free AI music prompt tool
Fix the prompt before you waste more credits.
If your AI song came back generic, messy, too vocal-heavy, or nothing like the idea in your head, the problem might not be the model. It might be the prompt.
Prompt Doctor helps you diagnose what went wrong, then rewrites your prompt with clearer structure, vocal control, texture, use case, and avoid rules.
Live assisted tool
Diagnose and rewrite a weak prompt
Paste your prompt, choose the main issue, and get a tighter next-generation version. This creates prompt rewrites, not audio files.
Diagnosis
• Add use case, structure, specific instruments, production texture, and avoid rules. • The prompt is short, so the model has too much room to guess. • Add avoid rules so the generator knows what not to do.
Rule-Based Rewrite
cinematic future bass, emotional, guitar, airy vocals, big drop, good for YouTube, clear use case, textured instrumentation, memorable motif, production texture, avoid generic stock music, polished creator-ready output, clear arrangement goal, strong edit points. Avoid: muddy mix, sudden key changes, random style switches.

Why AI music prompts fail
A lot of prompts fail because they ask for a vibe instead of giving direction.
“Cinematic future bass, emotional, big drop” might sound specific, but the model still has to guess the use case, vocal style, structure, mix density, drop shape, intro length, and what to avoid.
A stronger prompt tells the model what job the track needs to do.
Weak prompt
cinematic future bass, emotional, guitar, airy vocals, big drop
Stronger prompt
cinematic emotional future bass for a 45-second YouTube intro, 82 BPM, soft guitar motif, warm sidechained sub, glassy plucks, airy pads, short atmospheric intro, clean build, emotional instrumental drop, no full lead vocal, only soft chopped breath textures, clear edit points, clean ending. Avoid harsh festival EDM, muddy low end, random rap verses, long intro, sudden style switches, and busy vocals under voiceover.
Best workflow
Generate a prompt with the Suno Prompt Generator, paste it here, choose what went wrong, and copy the rewritten version for your next generation.
Next step
After generating with the rewritten prompt, use Keeper Score to decide if the output is worth saving, editing, covering, or regenerating.
Prompt Doctor FAQ
Can Prompt Doctor fix a bad Suno song?
It can help you fix the next prompt. It does not edit the audio file. If the song already exists, use the diagnosis to decide whether to cover it, regenerate it, or move on.
Why does Suno sing my prompt?
Sometimes the lyric box or prompt wording gives the model too much text that looks singable. Use short lyric-box directions, section tags, and clear instrumental-only rules.
Should I just regenerate instead?
Not always. If the prompt is vague, regeneration usually gives you a different version of the same problem. Fix the prompt first.
What should I do after rewriting the prompt?
Generate two to four versions, judge the first ten seconds, then run the best version through Keeper Score or Release Lab if you are preparing it for release.
