VoiceInk

VoiceInk is a dictation tool for macOS and iOS built around local models: transcription happens on the device, which is what lets it claim both speed and privacy at once rather than trading one for the other. It is open source, and works across every application rather than inside a single editor.

The features that matter are the ones addressing why dictation usually fails on real work. A custom dictionary teaches it names, product names and unusual spellings so they come out written correctly; smart replacements expand a short spoken phrase into exact text, which is how boilerplate like a scheduling link gets dictated without spelling it out.

The stated use cases are email, chat and prompting an AI assistant, and the company reports over 13,000 users.
