On your device or in the cloud: two ways to transcribe a conversation

When you set your phone on the table in a board meeting, a client negotiation or a doctor's appointment, the most sensitive thing in the room is not the summary. It is the raw audio.

Most note takers give you one answer to where that audio goes: their servers, every time. A few privacy-minded tools give the opposite answer and treat the cloud as something to apologise for. We think both miss the point. A flight to Lisbon and a ninety-minute workshop at your desk are different situations, and they deserve different tools.

So Parley Notes transcribes in two ways, and you choose with one switch.

On your device: the audio stays with you

Download the transcription model once, on your phone or in the Windows or Mac app, and your own device turns speech into text. The audio does not reach our servers. Only the text travels, over an encrypted connection, to be written up as your note.

This is the path for a plane, a basement plant room or a depot with no signal. The transcript is made on the spot and the note follows once you are back online. It is also the path for a room where the rule is simple: no audio leaves the building.

It has a cost, and we would rather say so. Speech recognition is heavy work for a phone. On a long day of site visits you will see it in the battery, and the first download takes space.

In the cloud there is nothing to set up and nothing is kept

The web app and the browser extensions work without installing a model, and the phone and desktop apps can do the same. The audio travels over an encrypted connection, our AI provider in the EU turns it into text, and we delete the audio as soon as the text is ready. If that ever fails, it is deleted automatically after one day.

It is also the more accurate path. In our own tests on real calls, the cloud made fewer than half the word errors of the model that runs on a phone. And your phone does none of the heavy work, even across back-to-back calls.

The cloud path is a conduit, not an archive. We do not keep your audio on our servers, and neither we nor our AI provider use your audio, your transcripts or your notes to train AI.

The same promise on both paths

Whichever way the words become text, the rest is the same. Your notes are stored in the EU. You can delete one note or everything, yourself, at any time. And if you turn on Private transcripts, your transcripts are locked with a key that stays on your devices. We store them, but we cannot open them.

You should not have to choose between a tool that is easy at your desk and one you can trust in the field. Use the switch, and pick the path that fits the room you are in.

Try it on your next meeting.
