The best offline dictation apps in 2026

Offline dictation means your voice is transcribed on your own machine, so nothing is uploaded to a server. It is the private, works-on-a-plane way to turn speech into text. Most popular dictation tools are cloud-based; only a handful actually run on-device.

We ranked the real offline options for macOS and Windows on privacy, accuracy, price, and how much they do beyond plain transcription. Dimmy is our own tool and we put it first, but the notes on each alternative are factual so you can judge for yourself.

Ranked on: genuinely on-device processing, price, platforms, and features beyond transcription. Competitor details checked on vendor sites in June 2026 and may change.

frequently asked

Dictate privately, on your own machine.

For most people on Mac or Windows, Dimmy is the best all-round choice: it can run Whisper fully on-device, is free and open-source, and adds AI cleanup, a voice command mode and meeting recaps. superwhisper is a strong Mac-first option, and Dragon is the legacy Windows pick if you already own it.
Yes, when the transcription runs on your own device the audio never has to reach a server. With local models Dimmy transcribes on your machine, and dictation audio is not kept unless you turn on audio in history. Be careful with "enhanced" built-in OS dictation, which can send audio to the cloud.
Modern local models like Whisper are very accurate. Dimmy lets you pick the model size to trade speed for accuracy, up to large-v3-turbo, so on-device accuracy is competitive with cloud tools for everyday use.
Yes. Dimmy is free if you build it from source and runs offline with local Whisper. Built-in OS dictation is also free but more limited and not always private.
