Tools

All tools are read-only.

• build_song_prompt: Turns a song idea into ready-to-paste style prompts for AI music models (genre, mood, instruments, vocals, tempo), title ideas and a section-by-section lyrics template with line and syllable targets.
• check_lyrics: Checks lyrics before you generate: syllables per line, lines that won't fit the melody, rhyme scheme per section, chorus length, missing section tags, overused words and the sung length.
• get_song_structure: Song structure for a genre and length (intro, verses, pre-chorus, chorus, bridge, drop, outro) with what each section should say.
• suggest_song_ideas: Song ideas for an occasion or topic: birthdays, weddings, anniversaries, pets, jingles, workouts, tributes and more.
• get_genre_guide: How a genre sounds and how to write for it: tempo, instruments, vocals, structure and lyric tips.
• get_music_model_guide: How to prompt one music model (Suno, Udio, MiniMax, Mureka, Lyria or OnMusic): its fields, section tags and tips.
• plan_singable_translation: Syllable targets for every line, so a translation can be sung to the same melody.
• list_song_options: The genres, moods, vocal types, lengths, occasions and models the tools understand.
