QuietSpeech

Hold Fn, speak, and the text appears wherever your cursor is, in any app. QuietSpeech uses Apple's speech recognizer and Apple Intelligence, so there is no API key to set up and dictation works offline. Select text and say how to change it to rewrite it, or say "generate" followed by an instruction for a first draft. A custom vocabulary keeps names and jargon spelled right.

It is a native SwiftUI menu bar app that uses under 60 MB of memory, with no account and no telemetry. The source code is published under GPLv3.

Pricing: $29 once for two Macs, no subscription, with a 14-day refund. Requires macOS 26 on Apple silicon.
