Offline vs Cloud Dictation on macOS - A Practical Guide

You speak faster than you type. The question is whether your tools can keep up.

This is a practical way to think about speed, accuracy, and privacy on macOS.

TL;DR

• Short phrases (5–15s): handshakes and round‑trips dominate cloud flows. On‑device avoids them.
• Long sessions (minutes): uploads and proxy hops add up. On‑device streams live and only finalizes the last ~30s when you stop.
• Accuracy: cleaner input beats heavy “prompt fixes.”
• Privacy: App Store sandboxed; your audio stays on your Mac.

What makes cloud feel slow (sometimes)

Cloud tools can be excellent. But for dictation, they pay a network tax: TLS/DNS handshakes, upload time (bigger if you avoid lossy compression), and often a proxy hop for a rewrite step. On hotel or café Wi‑Fi, this becomes noticeable, especially for very short or very long recordings.

Why on‑device feels steady

Voice Type streams locally and transcribes in ~30‑second windows. When you stop, we finish only the last window - typically ≈2–3 seconds on an M1 Mac. There’s no large file upload. If you enable bring‑your‑own‑key rewrites, we talk directly to your provider in a single hop.

Accuracy you can feel (without heavy prompting)

We normalize loudness, gently remove rumble, and detect speech vs background so the recognizer hears what you meant - not the room. This keeps transcripts faithful without forcing words via prompts.

Privacy and reviews you can verify

Distributed through the Mac App Store; Apple sandboxing applies. Reviews are genuine App Store reviews - critical ones included.

Where cloud still shines

Team workflows that need server‑side storage, specialized hosted models, or shared corpora can be a better fit in the cloud.
