Sponge Music's pitch is simple and it delivers on it: paste a line of inspiration or a full lyric sheet, wait under a minute, get a finished pop, hip-hop or "healing" mood track with sung Mandarin vocals that sound noticeably cleaner than most AI singers manage in Chinese. Being free, tied to a phone or Douyin login, and aimed squarely at casual creators rather than professionals is the whole point - this isn't trying to be a production tool.
ByteDance has also lined up licensing deals with rights holders including Universal Music, which matters given how contested AI-music training data and output ownership are in China right now. There's no developer API, no English interface, and no paid tier for higher fidelity or longer tracks, so treat it as a hobbyist app for Chinese-language songwriting rather than anything commercial-grade.
What people say
Sponge Music launched in 2024 as ByteDance's consumer entry into AI music, sitting alongside the company's other Douyin-adjacent products, and by mid-2026 industry trackers cite monthly visits north of 60,000 to haimian.com plus the standalone app. The core flow - type an inspiration line, upload a photo, or paste original lyrics, and get a complete arranged track with vocals back in under a minute - is consistently described the same way across Chinese AI-tool directories and press coverage.
Where it gets specific praise is Mandarin vocal quality: multiple Chinese-language write-ups (aixzd.com, gongke.net) single out clearer pronunciation and more natural emotional delivery in Chinese lyrics than rival tools manage, framing it as the default pick for Chinese-language AI songwriting rather than a general-purpose Suno competitor. The app's China App Store rating runs around 4.9/5, with recurring reviewer comments calling it "genuinely free" and praising newer features like full-album creation and voice recording for custom vocal input.
Coverage from late 2025/2026 (Tencent News' AIGC-music roundups) notes ByteDance has been securing licensing arrangements with major rights holders, Universal Music among them, positioning Sponge Music as one of the more legally cautious players in a space where training-data provenance and output copyright are actively disputed in Chinese legal and policy circles - a live issue for every AI music tool operating there, not unique to Sponge.
Limitations that turn up in commentary: no advanced editing or mixing controls beyond the initial generation, reliance on phone-number or Douyin login (no email signup found), and no public API for developers - it's positioned purely as a consumer creation and discovery app, integrated with CapCut and Douyin for distribution rather than as infrastructure other products build on. Chinese tech blogs also note that Haimian's shareable song links (via z.haimian.com) drop straight into Douyin comments and chat apps, which likely explains rising traffic without any visible paid-marketing push. No pricing changes have been reported; it remains free.
