About AceTagGen
AceTagGen is a free website with tools for writing prompts for SUNO, an AI music generator. It provides a structured Tag Builder that guides users through a 12-step process, a 100-point Prompt Scorer for checking a prompt before use, and a research blog with articles, guides, and tips about music tags. The homepage states that the tools need no signup.
The Tag Builder organizes a large tag library covering genre families, sub-genres, instruments, moods, vocal styles, and production tags. It includes live collision detection for conflicting tags, a character counter, and per-category limits, including the 1,000-character Style field limit. The site is focused on SUNO, so its tag system and techniques apply to that tool. The homepage's descriptions of how SUNO responds to tags come from the site's own research and are not independently verified here.
