AIVA

AIVA is a composition assistant rather than a prompt-to-audio toy: pick one of the more than 250 styles the site lists and you get a finished cue with a real arrangement, then open it in the editor and rewrite it note by note. Aiva Technologies SARL, the maker, puts two features up front that separate it from a plain generator — your own style model, and an audio or MIDI upload used as an influence on the result. Its strength is functional instrumental music: cinematic, orchestral and ambient cues for video, games and adverts, where the job is fixing eight bars, not regenerating the whole take.

The licensing is tiered by ownership rather than by download volume. The page states that copyright stays with AIVA on the Free and Standard plans — no monetization on Free, limited monetization on named video platforms for Standard — and assigns full copyright to you only on Pro, at €33 a month billed annually against €11 for Standard, both ex VAT. Stems are never mentioned and no training-data claim appears anywhere, so the provenance of the catalogue is unverified here and the terms deserve a read before commercial use. Where a rival wins: Soundraw documents stem export and bar-level muting up front and grants a perpetual worldwide licence with no ownership cliff.
