What is ACE-Step 1.5?
ACE-Step 1.5 is a music creator tool. AI music generator that composes full songs (verses, choruses, bridges) from a text prompt in under ten seconds, with vocals in 50+ languages, section-level Repaint editing, and MP3, WAV, or stem export. Free credits to start, paid tiers for commercial licensing.
ACE-Step 1.5 is a browser-based AI music generator that turns a written prompt into a complete song with lyrics, melody, and vocals. The site positions it around three claims: generation of a full four minute track in under ten seconds, vocal synthesis across more than 50 languages, and a training set limited to licensed and public domain material so output can be used commercially on paid plans. It is aimed at YouTubers, marketers, indie game developers, podcasters, and producers who need original audio without licensing stock libraries or hiring a composer. In practice the workflow is prompt-first. You describe the track you want (genre, mood, tempo, vocal type), set duration and style, and optionally paste your own lyrics for the engine to set to a melody. The output includes verse, chorus, and bridge structure rather than short loops. From there the Repaint editor lets you highlight a section and regenerate only that part, which is useful when a single verse or line of lyrics misses. Finished tracks export as MP3 or lossless WAV, and stem export separates vocals from instrumentals for mixing in a DAW. Where it fits: the homepage pitches ACE-Step 1.5 against Suno and Udio by emphasizing controllability and copyright safety over raw novelty, and against generic loop libraries by producing structured songs. The published examples span synth-R&B, Afrobeat, dream pop, hardstyle, glitch rock, and chiptune-adjacent styles, so the range is broad, though the site does not document per-genre accuracy. Accounts are credit-based. The free tier grants 9 credits on signup and a stated daily allowance of 50 credits (roughly 10 songs), while paid tiers bundle 99 to 700 credits with commercial licensing, stem and unlimited downloads, and concurrent task limits. Credits are described as non-expiring, and one-time purchases are offered alongside subscriptions.
How do you use ACE-Step 1.5?
1Open the generator and describe your track
Go to the generator and type a prompt covering genre, mood, tempo, and vocal type. Example given on the site: a high-energy EDM track for a fitness video, female vocals, 128 BPM.
2Set duration, style, and lyrics
Choose song length, mood, and style, and paste your own lyrics if you have them so the engine writes a melody around your words. Adjust vocal style and instrumentation at the same step.3Generate and preview
Run the generation and the track arrives in seconds. Listen through to check structure and vocal delivery before deciding what to keep.4Refine sections with Repaint
Highlight the part of the song that needs work, such as a single verse or a lyric line, and regenerate only that region while the rest stays intact.5Export and manage your tracks
Download as MP3 for sharing or WAV for editing, or pull stems for vocal and instrumental separation. Past generations are listed under My Creations.
6Pick a plan for commercial use
If the track is going into monetized content, compare credit bundles and confirm which tier includes the commercial license before publishing.
Pros and cons
Pros
- Full song generation in under ten seconds, which makes rapid iteration through dozens of prompt variations practicalAI

Cons
