You hit “record” or drag in an audio file. You grab a coffee, scroll Twitter, check your notes—and wonder: “Wait… is this transcribing yet?”
Vocal Prism ends the guessing. Your audio turns into text in real time, fully locally on your Mac. Drag, drop, watch the waveform, read the transcription. Done.
Works with audio you already have:
MP3, WAV, FLAC, M4A
Podcasts, lectures, interviews
Quick personal memos
Each transcription happens instantly, with a live waveform so you see progress at a glance. Done? Copy, export, or keep going.
Why?
Other transcription tools send your audio to the cloud, charge per minute, or hide results behind clunky interfaces. You just want fast, accurate text without giving up privacy.
