Dictara turns speech into text entirely on your Mac. Recognition and speaker separation run on your Apple Silicon chip — audio and the transcript never leave the device. No data processor, no third-country transfer, nothing to subpoena or sell off.
How on-device transcription works
Most "private" transcription tools still send your audio to their cloud to be processed, then promise to delete it. Dictara never sends it in the first place. The entire pipeline ships inside the app and runs on your Apple Silicon chip, so there is simply no upload to leak, seize, or train on.
Speech-to-text runs on NVIDIA Parakeet, built into the app and executed on-device. Around 30× real-time, with clean punctuation and capitalization — no API call, no server round-trip.
For meetings, speaker separation runs on sherpa-onnx — also fully on-device. Who-said-what is worked out on your Mac, never in a datacentre.
Every transcript is written as Markdown to a folder you own — searchable, optionally in your own Dropbox. Your files, your format, no lock-in.
The only network contact Dictara makes is an optional, anonymous version check. Never your audio, never your text.
Why local matters
When transcription happens in the cloud, your words become someone else's data: an asset that can be breached, compelled by a court, used to train a model, or — the part nobody talks about — sold when the company behind it fails.
Cloud AI startups are VC-funded and grow on other people's money. Some get huge, some fail. And when one fails, its data store becomes part of the bankruptcy estate: an asset, sellable to a third party you never agreed to. In 2025, 23andMe's data on 15 million people went into exactly that kind of auction. Not a great feeling, knowing your dictated emails, contracts and thoughts could one day belong to someone as an asset.
Dictara has no server that could ever fall into a bankruptcy estate. Your words are your capital — and they're nobody else's business.
A cloud provider can be forced to hand over the recordings it holds. Dictara holds nothing — your transcripts sit only on your Mac, in your possession. There is no third party to serve.
Local processing means there's no provider to bind to a data-processing agreement and no third-country transfer for your dictation. The disclosure that triggers the rules never happens.
Your voice can't quietly become someone's training data when it never leaves your device. There's no corpus to opt out of, because there's no corpus.

Data handling, side by side
The one question that decides everything about privacy: does your audio leave the device? For Dictara the answer is no — and that single fact removes every downstream risk at once.
| Dictara | Wispr Flow | Otter | |
|---|---|---|---|
| Where audio is processed | On your Mac, on-device | Cloud | Cloud |
| Where transcripts live | Your drive only | Vendor cloud | Vendor cloud |
| Account / login | None | Required | Required |
| Can be subpoenaed from a vendor? | No vendor holds it | Yes — provider holds it | Yes — provider holds it |
| If the vendor goes bankrupt | Nothing sits with the vendor | Cloud store = potential estate asset | Cloud store = potential estate asset |
| Privacy is… | The architecture | Cloud service with privacy controls | Policy you have to trust |
As of June 2026. Vendor terms change — verify before deciding.
Wispr Flow offers privacy controls for a cloud workflow. Dictara takes the simpler route: core transcription is local by architecture, so there is no Dictara cloud holding your words.
More than transcription
Private transcription is the foundation. On top of it, Dictara is a full local tool: tap a key to dictate into any app, record meetings with on-device speaker separation, and keep a searchable diary you can optionally analyze with your own AI.
Tap the right ⌥, speak, tap again — clean text lands at your cursor in Slack, Mail, Word, your browser, every Mac app. Offline, in a heartbeat. Dictate into any app →
Hit record before a call; Dictara detects the conversation and splits it by speaker — locally, with no note-taker joining the call. Meeting notes with no bot →
Point Claude or Codex at your local diary for daily summaries and a private knowledge base. Dictara itself uploads nothing; the connected AI tool uses your own account and provider terms.
Questions
It's an app that turns speech into text entirely on your own machine, with no upload to a server. Dictara runs speech recognition (NVIDIA Parakeet) and speaker separation (sherpa-onnx) on your Apple Silicon chip — audio and text never leave the device, not even the transcription. There's no cloud account and nothing is stored on anyone else's server.
Use a tool that processes audio locally. With Dictara, the models are built into the app and run on-device, so the recording is transcribed on your Mac and the result is written to a Markdown file on your own drive. The only network contact is an optional, anonymous version check; never content.
Local processing means there's no data processor to contract with and no third-country transfer for the dictation itself, because the audio and transcript never leave your device. There's no server holding your content that could be breached, seized, or sold off. (This is a general overview, not legal advice.)
There's no cloud provider holding your recordings to be served with a subpoena. Your transcripts sit only on your Mac, in your possession. With cloud transcription, a provider can be compelled to hand over data it holds; with Dictara there is no such third party. (This is a general overview, not legal advice.)
Nothing, because nothing sits with the vendor. Dictara has no server that could ever fall into a bankruptcy estate. When a cloud AI company fails, its data store becomes an asset that can be sold to a third party you never agreed to — that risk simply doesn't exist when the data only ever lived on your own machine.
It's free during Early Access. After that, a one-time licence per machine — no subscription, no hour packs, no recurring cost. Everything runs locally, so there's no metered usage. Requires macOS 12 or newer on Apple Silicon.
