Private voice for iPhone, iPad & Mac

Your voice becomes clean text, and never leaves your device.

Dictation, transcription and meeting notes that tell the speakers apart, all written up by on-device AI. No cloud, no account, nothing uploaded.

The idea

Your words are yours. They should not go to someone else’s cloud.

Most voice apps ship your audio to a server to turn it into text. Dictum does the whole job on your own device: the transcription, the clean-up, the speaker separation, the sensitivity check and the export. The audio and the words never leave your iPhone, iPad or Mac, so there is nothing to leak, subpoena or sell.

How it works

Spoken to sent, in three steps.

01 · CAPTURE

Speak, drop or record

Dictate a thought, import an audio file, or record a whole meeting. Dictum takes it from there.

02 · UNDERSTAND

Transcribed on-device

On-device AI writes it up with timestamps, tells the speakers apart, and labels anything sensitive, privately.

03 · EXPORT

Ready to send

One tap turns a meeting into a polished PDF or Word document, or saves the audio as an mp3.

Know who said what. Automatically.

Record a meeting and Dictum separates each voice on your device, labels every line by speaker, and shows a talk-time breakdown. It works out how many people spoke on its own, with no voice enrolment and no cloud. Tap any speaker to give them a real name and the whole transcript updates.

Everything on your device

One private place for every word.

Dictate

Speak and Dictum turns it into clean text, stripping filler and fixing punctuation, in your own dialect.

Transcribe

Import any recording, m4a, mp3, wav and more, and read it back as a timestamped, searchable transcript.

Who said what

Meetings are split by speaker on-device, with a talk-time breakdown and one-tap naming.

Sensitivity check

Every transcript is scanned privately and labelled, so nothing confidential slips out by accident.

PDF & Word export

Turn a meeting into a presentation-ready document with summary, decisions and an action-items table.

Private by design

No cloud, no account, no tracking. Dictum can run in airplane mode because it never needs a network.

Questions

Good to know.

Is my audio uploaded anywhere?

No. Every step, the transcription, the clean-up, the speaker separation, the sensitivity check and the export, runs on your own device. There is no account and no cloud, so the audio and the words stay with you.

How does it tell the speakers apart?

Dictum listens for when the voice changes and groups the segments that sound like the same person, entirely on-device. It works out how many people spoke on its own, with no voice enrolment. You tap a speaker once to give them a real name.

Which audio files can I bring in?

Common recordings including m4a, mp3, wav, flac and more. Dictum reads them back as a timestamped, searchable transcript and can re-encode the audio to mp3 for you.

Does it work offline?

Yes. Dictum never needs a network, so it works anywhere, in airplane mode included.

Which devices does it run on?

iPhone, iPad and Mac. One Universal Purchase covers all three, and your sessions stay on whichever device holds them.
