Transcription for Mac · on-device
The recording never leaves your Mac.
VibeVerter transcribes audio and video on your own Mac — it labels each speaker, links every line to the second it was spoken, and saves the result as Word, PDF or plain text. No account. No upload. No monthly bill.
Apple silicon · macOS 26.2+ · free to try
That part already works. Every line links back to the audio — open the HTML copy next to the PDF and clicking a timestamp jumps the player straight to that moment.
Good. Then we ship it that way.
One window. Three jobs it does properly.
VibeVerter grew out of one person needing accurate transcripts of long calls without handing the audio to a website. Every part of it is built around that.
- Speakers
- Speaker detection separates the voices and labels them Speaker 1, Speaker 2, and so on. When the run finishes it plays you a few seconds of each and asks for real names; every line in the document updates at once. pyannote · community-1 model, bundled — no sign-up
- Timestamps
- Every paragraph is stamped with the time it was said. In the HTML copy the stamp is a link: click it and the built-in player jumps to that second. Word and PDF carry the same links back to the audio.
- Documents
- Export to Word (.docx), PDF or plain text — laid out as real speaker turns with punctuation and paragraphs, not one unbroken block. Hesitations and repeated false starts are tidied out; nothing is ever added.
- Convert
- Turn any audio file into MP3 at the bitrate you choose. Drag a whole folder in and it works through the queue, skipping anything that isn’t audio or video.
- Video
- Pull a clean audio track out of a video file — MP3, M4A, WAV, FLAC or OGG — without re‑encoding the picture or needing a separate tool.
- Record
- Record your voice, whatever is playing on your Mac, or both, mixed into one file that drops straight into the queue. What is playing is recorded by the app itself — nothing to install, through any speakers or headphones, Bluetooth included. A live level meter shows it is hearing you before you start, Pause and Resume hold a recording without ending it, a recording that comes in quietly is made louder for you, and you can play it back before you transcribe or convert it. Mute my voice stops your side being recorded while a call carries on, a small bar keeps the controls reachable over Zoom or a video, and a keyboard shortcut mutes from any app. Name a recording as you save it. Forget to stop, and VibeVerter asks whether you are still recording, then pauses by itself if no one answers. Like everything else here, it stays on your Mac. macOS asks for permission once for the microphone and once for computer audio · only record people who know about it and have agreed
- Engine
- Transcription runs on Whisper large-v3-turbo through Apple’s MLX framework, using the GPU in your M‑series chip. A one‑hour recording is done in a few minutes. first run downloads the model once (~1.5 GB); after that it is fully offline
A web transcription service keeps a copy of your recording on its servers. For a privileged call, a patient session, an unpublished source or anything under an NDA, that copy is the problem.
VibeVerter has no servers. The audio, the transcript and the model all stay on your Mac. Download the speech model once, then turn off Wi-Fi if you like — it still works.
That also means there is no per-minute meter and no seat licence. You are running a program on your own computer, the way software used to work.
Add, choose, start.

Drag audio or video onto the window, use Add Files / Add Folders, or press Record to make a new one. One file or a hundred.

Built on open work
Speaker detection uses the pyannote speaker-diarization-community-1 model by Hervé Bredin and the pyannote team, released under CC BY 4.0 and redistributed inside VibeVerter under those terms. Transcription uses OpenAI’s Whisper model (MIT) in the MLX-community conversion, run through Apple’s MLX (MIT).
Media handling uses FFmpeg, LAME and the Xiph codecs, built and included under the LGPL 2.1. You may obtain the corresponding source for those components — including any changes — from code@vibeverter.app, for no more than the cost of distribution. This offer is valid for three years from the date you received your copy.
