A Wispr Flow alternative that keeps your voice on your Mac.

Both turn speech into text in whatever app you are already in. The difference is where your voice goes to become text — and on that, the two products are built on opposite decisions.

The short answer

Choose Uttrflow if the recording never leaving your machine matters to you, and you are on an Apple-silicon Mac. Speech becomes text on the Mac in front of you. No recording is uploaded, and the audio is deleted from your Mac the moment it becomes text, so there is no copy on a server to set a retention policy for or ask anyone to delete.

Choose Wispr Flow if you need more than a Mac. It runs on Mac, Windows, iPhone and Android, supports 100+ languages, and includes a meeting notetaker — none of which Uttrflow does. If you dictate across devices, that is not a close call.

Where your voice goes

This is the real difference, and it is worth being precise rather than dramatic about it.

Wispr Flow’s own privacy page says “we never sell your data”, that you decide “whether data can be used to train or improve our models”, and that you can “choose what’s stored and delete it any time”. It lists SOC 2 Type II and ISO 27001 for Enterprise plans, and HIPAA with a signed BAA. Those are real, and they are more compliance paperwork than we have.

They are also controls over data that has been sent somewhere. Uttrflow does not have those controls, because there is no recording on a server to opt out of, train on, or delete. That is the trade in one sentence: they give you good controls over your data; we do not take the audio in the first place. Which you prefer is a real choice, not a trick question.

How the two compare

• Where speech becomes text. Uttrflow: on your Mac. Wispr Flow: on their service, with the retention and training controls described above.
• Working offline. Uttrflow needs the network exactly once, to sign in on first run. After that it dictates with the Wi-Fi off — which is the only test of an on-device claim that means anything.
• Platforms. Wispr Flow: Mac, Windows, iPhone, Android. Uttrflow: Apple-silicon Macs on macOS 26 or later, and nothing else.
• Languages. Wispr Flow publishes 100+. Uttrflow does not make a comparable claim.
• Meetings. Wispr Flow has a notetaker that records and summarises meetings. Uttrflow has nothing equivalent.
• Clipboard history. Uttrflow keeps what you copy, searchable, on that Mac, behind the same kind of shortcut. It is a second tool in the same app.
• Your vocabulary. Both learn the names and jargon you use. In Uttrflow the dictionary is what your account carries between Macs — your recordings never are.

Is Uttrflow free?

It is free to download and there is a paid tier. Wispr Flow also has a free tier and paid plans; their current numbers are on their pricing page rather than repeated here, because a price copied onto somebody else’s comparison page goes stale and then misleads.

Do I need an account?

Yes — Uttrflow asks you to sign in once, on first run. The account exists so your dictionary and your subscription follow you to your next Mac. It is not what makes dictation work: after that first sign-in the app never needs the network again, because the transcription was never happening anywhere else.

Switching

There is nothing to migrate. Both work by holding a key in whatever app you are already in, so the muscle memory transfers; the words you have taught one will need teaching to the other. Download Uttrflow for macOS and try it with the network off — that is the test that tells you whether the difference above is real.
