Whisperkit vs Solum

Whisper turns speech into accurate text — entirely on your device. Powered by Apple's Neural Engine and an open-source multilingual speech recognition model, Whisper transcribes audio recordings, voice memos, lectures, meetings, podcasts and videos directly on your iPhone. Nothing is uploaded. Nothing is tracked. No accounts. New: make music (beta). Describe a song — style, mood, instruments, even lyrics — and Whisper composes it on your device.
