Udio is an AI music generator built by Uncharted Labs that produces high-fidelity songs with vocals and instrumentation from text prompts. Launched in April 2024 to immediate acclaim for audio quality, Udio distinguishes itself from Suno with inpainting (the ability to edit specific sections of a generated clip) and one of the largest free tiers in the space at 1,200 credits per month. It carries a complicated legal history — the RIAA filed suit against Udio in June 2024 over alleged training on copyrighted recordings; the case settled in early 2025 under undisclosed terms.
What It Does
Udio generates 32-second music clips from text prompts with custom tags for genre, mood, tempo, and instrumentation. Clips can be extended to full-length songs by generating additional 32-second continuations. The inpainting feature allows users to select a specific time range within a generated clip and regenerate just that section, enabling targeted editing without restarting from scratch (Udio).
Who It’s For
- Audio quality seekers: users who find Suno’s output too polished/generic and want more raw sonic texture
- Music producers: inpainting and granular generation controls appeal to producers using AI as a creative tool
- Budget-conscious creators: the free tier (1,200 credits/month) is larger than most competitors
- Experimental musicians: Udio handles niche and unusual genre combinations better than Suno in many cases
- Developers: API access on paid plans for integrating AI music into apps
Pricing
Udio costs $0-$30/month across three tiers. All tiers include commercial use rights. The free tier’s 1,200 monthly credits is one of the most generous in AI music as of April 2026 (Udio Pricing).

Key Features
- High audio fidelity: Udio’s output is widely regarded as having more sonic texture and realism than Suno, particularly for genres like jazz, classical, and metal where instrumental detail matters (Udio).
- Inpainting: select any time range in a generated clip and regenerate only that section. This is unique among consumer AI music tools and dramatically improves editing control.
- Custom tags system: beyond text prompts, Udio supports granular tags for genre, sub-genre, mood, instruments, era, and BPM — more specific control than Suno’s prompt-only approach.
- 32-second clip extension: generate a seed clip, then extend it forward or backward in 32-second increments to build full-length tracks with coherent structure.
- Generous free tier: 1,200 credits per month on the free plan. At roughly one credit per second of audio, this is approximately 20 minutes of generated music monthly at no cost.
- Commercial license on all tiers: unlike Suno, Udio includes commercial use rights even on the free tier (with attribution requirement removed on paid plans).
Limitations
- RIAA lawsuit history (settled 2025): the Recording Industry Association of America sued Udio and Suno in June 2024 for training on copyrighted recordings. Udio settled in early 2025 on undisclosed terms. This introduces residual legal uncertainty around the provenance of Udio’s training data, which matters for commercial deployments in risk-averse contexts.
- Smaller feature set than Suno: Udio lacks cover art generation, has a less polished extend workflow, and the overall product surface is narrower. Suno has had longer to iterate on UX.
- Company viability questions: Uncharted Labs is a smaller, less-funded company than Suno AI. Post-lawsuit settlement, long-term platform viability is less certain — a real risk for users building workflows around the tool.
- Less vocal generation polish: Udio’s vocals can sound less natural than Suno’s, particularly for pop and mainstream genres where Suno has clearly optimized.
- No affiliate program: no referral commissions available, limiting the tool’s presence in affiliate-driven review content.
Bottom Line
Udio is the better choice for users who prioritize audio fidelity, inpainting control, and a large free tier over Suno’s more polished and commercially established platform. The 1,200 free credits per month make it easy to evaluate without spending anything. The RIAA settlement and smaller company footprint introduce longevity risk — factor that in for any long-term workflow dependency. If you want the easier, better-supported option, Suno is safer. If you want the highest-quality output for experimental or niche genres, try Udio.
Best Alternatives
- Suno: more polished UX, stronger vocal generation for pop/mainstream genres, better commercial track record, affiliate program. The safer long-term bet.
- Mubert: royalty-free background music for content creators. No vocals, no RIAA lawsuit risk, different use case entirely.
- Soundraw: subscription-based background music AI. Less creative flexibility than Udio but safer for content monetization.
FAQ
Is Udio free? Yes. Udio’s free plan provides 1,200 credits per month — one of the largest free tiers in AI music generation. At approximately one credit per second of audio, this equates to roughly 20 minutes of generated music per month at no cost. Free-tier output includes commercial use rights with attribution. No credit card is required to start.
What happened with Udio’s RIAA lawsuit? In June 2024, the Recording Industry Association of America filed suit against Udio (and separately against Suno) alleging that both companies trained their AI models on copyrighted music recordings without permission. Udio settled the lawsuit in early 2025; the specific terms — including any licensing payments or behavioral changes — were not made fully public. The settlement is widely interpreted as resolving direct liability for Udio as a company, but some legal ambiguity around training data provenance remains in the broader AI music space.
Is Udio better than Suno? It depends on the use case. Udio generally produces higher raw audio fidelity, especially for genres with complex instrumentation (jazz, metal, classical). Its inpainting feature is unique and powerful for iterative editing. Suno leads on vocal generation polish, ease of use, product maturity, and overall brand recognition. The Suno Pro plan ($8/mo) is also cheaper than Udio Standard ($10/mo) for similar output volume. Most casual users prefer Suno; audiophiles and producers often prefer Udio’s output quality.
