How they differ, in plain terms
All three turn a text prompt into music, but they read prompts differently — so the same idea should be written differently for each. Suno and Udio want a short, comma-separated style string; Lyria wants a single descriptive sentence you type into a chat box.
Prompt format
Suno rewards terse tags (“k-pop, female vocals, 120 BPM”). Udio is similar but leans more descriptive and lets you exclude elements. Lyria folds everything into one prose sentence and even accepts a musical key.
Where you actually use them
Suno and Udio are dedicated web apps. Lyria lives inside the Gemini app, Google Flow, and YouTube Dream Track — there's no separate style field, you just chat.
Which should you pick?
There's no single winner. Choose Suno for fast structured songs with your lyrics, Udio for detailed control and negatives, and Lyria for quick ideas in chat with precise tempo and key. Our free generators write the right kind of prompt for each.
