Udio is an AI music platform with its own plans, terms, and sharing features. IronSound is a private studio. One prompt becomes a file you can keep: vocals and lyrics, the mix as MP3 or studio WAV, and a per-song license, plus stems and a streaming master on full songs and studio WAVs (not 30-second clips). No public feed, credits instead of a subscription.

Both turn prompts into music. Both use AI models. If public sharing and a community are what you want, a platform built around them may suit you better.
IronSound is a private AI song studio. One prompt becomes a file you can keep: vocals and lyrics, the mix as MP3 or studio WAV, and a per-song license, plus stems and a streaming master on full songs and studio WAVs (not 30-second clips).
Signup includes 10 free credits. A full song costs 10 credits, a 30-second clip costs 1 credit, and a studio WAV master costs 20 credits. Credit packs are one-time purchases: 50 credits for $5, 200 credits for $15, and 500 credits for $30.
The mix (MP3 or studio WAV) and a license.txt, all private to your library, plus stems and a streaming master on full songs and studio WAVs (not 30-second clips). Vocals and drums are separated from the mix; bass and other are derived reference tracks, not separated stems.
You may use songs you generate, including commercially, under the per-song license. Full songs are made with YuE2-3B, self-hosted on IronSound-operated servers, when that engine is available; otherwise they fall back to Google Lyria 3.5. 30-second clips use Google Lyria 3 Clip, and studio WAV masters use Google Lyria 3.5. Lyria output carries an inaudible Google SynthID watermark; YuE2-3B output does not. Each song's license file names the engine that made it. Lyria tracks are also subject to Google Gemini paid API terms. Do not clone a specific artist's voice, submit copyrighted lyrics you do not own, or generate content that violates applicable law.
