Sign-up gives you 25 welcome credits — enough for two full songs to try the engine — and no credit card required. Paid plans kick in when you want to keep generating beyond the welcome batch.

Commercial use comes with the paid plans, where each export carries a downloadable license document keyed to your account — publish to streaming, monetised video, podcasts, and ads without case-by-case approval. The free tier is for personal use.

Both ride strong text-to-music backbones. The audible gap most people notice is in lyric craft and section structure, not raw timbre — AISongGen ships rhyme + meter analysis built into the lyric editor, while Suno gives you a plain textarea. For genres where Suno is dominant (English pop), expect rough parity on the masters; for non-English vocals or lyrically dense genres, AISongGen tends to write better verses.

Yes — every paid plan includes 6-stem separation (vocals, drums, bass, guitar, piano, other). Suno Pro ships 12 stems and a full Studio DAW, so if you need every micro-element split out for a stadium-grade mix Suno still wins on track count. For most workflows — replacing vocals, isolating bass for a remix, dropping drums into a beat — 6 stems are plenty.

AISongGen does not import Suno generations directly, but you can use our Cover tool to feed a Suno-generated mp3 in as a style reference and produce a new track in the same vibe. The new track lives in your AISongGen library with a clean license you fully own.

Standard $9.99/month gives 500 credits (around 50 songs); Pro $23.99/month gives 2000 credits (around 200 songs). Suno's Pro is also $10/month but credits convert to roughly 500 songs because they bill 5 credits per song instead of 10. We keep prices aligned with tad.ai's public tiers; the differentiation is what you get per credit, not the headline number.
