A builder for the “Style of Music” box you fill in when making a track in Suno or Udio — just click tags to assemble the string. Pick from curated descriptor chips across genre (pop, rock, lo-fi hip hop, synthwave, anime, city pop and more), mood (uplifting, chill, epic, melancholic…), vocals (female vocals, male vocals, duet, instrumental…), instruments (piano, electric guitar, synth, 808 bass, strings…) and production/era (lo-fi, 80s, vintage, reverb-heavy…), and you instantly get a comma-separated string like `lo-fi hip hop, chill, female vocals, piano, 90 bpm` that you copy straight into the style box. Descriptors are in English because Suno and Udio respond best to English style tags. From the toolbar you can add a BPM (tempo) and a musical key (such as C minor), and a free-text field lets you mix in your own words. The style box has an approximate character limit, so the tool always shows the descriptor count and character count and warns you when you go over the typical limit. Quick presets — Lo-fi study beats, Epic cinematic, 80s synthwave and more — drop in a proven combination in one click so you can tweak from there. Writing a style box from a blank field is where people stall: which words actually work, what order, will it fit. This tool removes that friction by letting you pick from words that land. It's pure string assembly with no external API or data, so the tags you pick and the words you type are never sent anywhere — everything is processed locally in your browser. It does not generate lyrics or audio (that's what Suno/Udio itself is for).
