§ STT engines
STT engines
Dictation and meetings can pick different STT engines. Bundled WhisperKit tiers and a Parakeet-class local engine ship by default. Cloud STT is opt-in, BYOK, and currently used for dictation paths only.
Who this is for
Users picking the right speed/accuracy tradeoff for their Mac, and anyone who wants to run hosted STT for specific recordings.
Choosing a tier
Smaller WhisperKit tiers run faster with lower accuracy on long-form audio. Larger tiers are slower but cleaner. On an M1 Max or better, the larger tiers are usually fast enough for live transcription. On an M1 Air, the smaller tiers are the better default.
