JustScribe is a local-first live transcription app for macOS that converts speech into text in real time, entirely on your Mac. It runs on-device AI models, so your audio never leaves the machine and it keeps working without an internet connection. It suits anyone who types a lot and would rather talk, from writers drafting articles to teams taking meeting notes.
About JustScribe
What Is JustScribe
JustScribe is a Mac app that turns your voice into text as you speak. You pick an audio source, hit record, and watch words appear within a second or less. There's no cloud round trip, no account, and no telemetry, because all the speech recognition happens locally on your hardware. Think of it as private transcription that never asks for your login.
The pitch is simple: typing is slow, and most cloud transcription tools send your audio somewhere you don't control. JustScribe closes that gap by running on Apple Silicon and using two AI models under the hood. It's built for people who care about both speed and keeping conversations private. It's also on-device dictation that works the moment you open it.
The trade-off is scope. This is a Mac-only tool, and it works best on Apple Silicon machines. If you're on Windows, Android, or an older Intel Mac, it isn't for you. The app also leans on its on-device models rather than a cloud engine, which can matter more for some accents and noisy rooms than it does for clean close-mic speech.
Getting Started
- Download JustScribe from the Mac App Store and open it. No sign-up or account is required.
- Grant microphone and accessibility permissions when macOS asks, so the app can capture audio and paste text into other apps.
- Choose your audio source: your microphone, system audio, or a specific app.
- Hit record and start talking. Your words appear live on screen with low latency.
- Copy the transcript or export it to text, then drop it into your notes, editor, or chat app.
The whole setup takes a couple of minutes, and the only real friction is the permission prompts, which macOS shows for any app that wants to listen and type on your behalf.

Key features
Real-Time On-Device Transcription
Words show up as you speak, with latency under a second according to the developer. The recognition runs on your Mac's own hardware, so there's no upload delay and no server queue. For anyone used to waiting on cloud transcription, the difference is noticeable. It feels instant. That speed comes from keeping everything local. No file gets uploaded, so nothing waits in a line behind other people's audio. You talk, and the text is just there.
Two AI Models Under the Hood
JustScribe ships with Parakeet for fast English transcription and Whisper for 50+ languages. You pick the model that fits the job. Parakeet is the quicker option for English; Whisper widens coverage when you're working in another language, at the cost of a bit more processing on the same machine.
Voice Typing That Beats the Keyboard
The developer claims you can speak roughly four times faster than you type. In practice that means drafting an email or a document by talking through it, then cleaning up the text. It's the core reason to keep the app running in the background.
Privacy by Default
Audio stays on your Mac. There's no cloud processing, no account, and no data collection, according to the developer. That's the whole point of a local-first tool, and it's the feature that separates JustScribe from most transcription services, which route every recording through servers you'll never see and can't audit, storing the audio for as long as their policies allow. Not much to argue with there.
Any Audio Source
You can transcribe your microphone, your system audio, or a specific app. That covers live meetings, podcasts, videos, and anything else playing on your machine. Capturing system audio means you don't have to hold a mic to a speaker. That's a small thing that turns out to matter a lot on long calls. Recording a two-hour meeting? You can. Just point it at the app window and let it run.
Built for Apple Silicon
The app is written for Apple Silicon from the ground up, which is why it can run modern speech models without hammering your battery. On older Intel Macs, expect it to miss the performance the developer designed around. So what does that mean if you own a five-year-old MacBook? Honestly, it might not be worth it. The models need the speed.
Pros and cons
Pros
- Audio never leaves your device, which matters for confidential meetings and interviews.
- Works with no internet connection, so it's usable offline and in air-gapped environments.
- No account and no sign-up, so there's nothing to register or leak.
- Two model choices let you trade speed for language coverage.
- Can capture system audio, so it works on calls and videos, not just your own voice.
Cons
- macOS only, and optimized for Apple Silicon, so Windows and older Intel Mac users are left out.
- The on-device models can struggle more than cloud engines with heavy accents or very noisy rooms.
- There's no cloud sync or team sharing, so transcripts stay on the one Mac where you recorded them.
