Riffusion is a fun toy. AISongGen is a production tool.Long-form, vocal-driven, license-clean
Updated April 2026
Riffusion is great for short experimental clips. AISongGen is built for finished songs you can publish — full vocal-driven tracks up to eight minutes, with stems and MIDI export in the library and a commercial license on the paid plans.
Songs, not sketches
Riffusion clips top out short and arrangement is whatever the diffusion produces. AISongGen renders verse-chorus-bridge structure on demand, with section locks so you can rebuild parts without losing the bits you love.
- Up to 8 minutes on Pro
- Verse, chorus, bridge, and outro markers
- Section locks prevent regeneration drift
Real lyrics, real vocal performances
Riffusion focuses on instrumental textures. AISongGen ships a reasoning-first lyric model and a vocal generator that performs the lyric with verse / chorus phrasing, breath, and consonant attack in the right places.
- AI-drafted lyric pass before audio generation
- Choose male, female, or instrumental voicing
- Section-aware vocal phrasing and breath placement
Every track ready for distribution
AISongGen exports MP3, WAV, FLAC, stems, and MIDI — Riffusion exports clip audio. Every AISongGen export ships with a downloadable license document tied to your account.
- MP3, WAV, FLAC and stems on Standard and above
- MIDI for melody and harmony on Pro

Frequently asked questions
The questions creators most often ask before switching from Riffusion.
Riffusion looks free — why pay for AISongGen?
Riffusion's web app is free for short experimental clips and that is great for sketching ideas. Once you want a finished song with vocals, verse-chorus structure, stems, and a license you can publish under, the gap to a production-grade tool gets large. AISongGen gives 25 welcome credits at sign-up — enough to ship a couple of full songs and decide for yourself.
Can Riffusion generate vocals like AISongGen?
Riffusion is fundamentally instrumental — it diffuses on spectrograms and was not designed around vocal phrasing. AISongGen drafts the lyric first, then performs it with section-aware breath placement and consonant attack. If your project needs sung vocals, this is the practical difference.
How long can my songs be on AISongGen vs Riffusion?
AISongGen renders up to 4 minutes on Standard and 8 minutes on Pro with verse / chorus / bridge structure markers. Riffusion clips are short by design — useful for loops and sketches, not for finished tracks.
Does Riffusion offer stems?
No — Riffusion exports the master only. AISongGen ships 6-stem separation (vocals / drums / bass / guitar / piano / other) on every paid plan, ready to drop into Ableton or Logic.
Is the audio quality really that different?
Yes — and you can tell on a single playthrough. Riffusion's diffusion-on-spectrogram approach produces the lo-fi watery artefacts the technique is known for. AISongGen runs a final mastering pass at -14 LUFS with phase-coherent low end, so tracks survive Bluetooth and earbud playback.
Can I use AISongGen songs commercially?
Commercial use comes with the paid plans; each export carries a downloadable license document keyed to your account, suitable for monetised video, podcasts, ads, and streaming. Riffusion's commercial licensing is less explicit.
