OpenAI Whisper
Whisper is OpenAI's open-source, MIT-licensed speech-to-text model trained on 680,000 hours of audio -- you can download it and run transcription fully offline and free on your own hardware. It supports ~99 languages plus translation to English and is remarkably robust to accents and noise. If you don't want to run GPUs, OpenAI's hosted transcription API runs Whisper (and newer gpt-4o-transcribe models) at roughly $0.006/min. It has no built-in speaker diarization and the core repo updates infrequently, but the surrounding ecosystem (whisper.cpp, faster-whisper, WhisperX) is enormous.
AIVA
AIVA is one of the original AI music composers, focused on editable, multi-track compositions across 250+ styles, with custom style-model training. Its standout feature is ownership: the Pro tier (EUR 49/mo, or EUR 33 billed yearly) hands you full, permanent copyright of your compositions -- something most generators don't offer. Free and Standard tiers keep copyright with AIVA and require credit, and there's no public self-serve API. Pricing is in EUR plus VAT, which makes it pricier for US buyers. It's the best pick when you need to truly own and edit what you generate.
OpenAI Whisper edges AIVA on aggregate — 88 vs 73.
The default open-source speech-to-text -- free and offline if you self-host, or ~$0.006/min via OpenAI's API when you don't want to run GPUs. AIVA still wins for buyers who prioritise pro tier grants full copyright ownership. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
