Yinso
Yinso turns a short story, a mood, or a set of lyrics into an original song you can play in the browser. You type a prompt, pick the YS, M, or T model, and optionally flip the track to instrumental. It is a song generator for people who want a finished vocal or backing track without opening a DAW first.
The generate button is not one anonymous model. YS is marked recommended and goes to 8 minutes, M tops out at 6 with cleaner mixing, and T stops at 4 but is built for continuation. Those published caps are the real product spec, not a slogan.
Songwriters get a Simple prompt box plus an Advanced workspace with a 3,000-character lyrics field, a 1,000-character style prompt, and optional reference audio. Write with AI will draft lyric suggestions, and Yinso states outright that this helper is not a chat assistant. Remixers can split an uploaded track into vocals, drums, and bass (lossless, about a minute) or reverse-prompt a file of up to 100 MB for 5 credits.
A public Discover feed lists community tracks with genre tags, including songs in Chinese, Thai, French, and English. The site UI itself is available in English, Simplified Chinese, Traditional Chinese, and Spanish.
