How it works

Three steps, then nothing.

No note-taking, no fiddling. Turn it on and focus on the conversation.

1

Turn on listening

Start with a single toggle on Today — or schedule it to listen only during the hours you choose.

2

Just talk

Meetings, calls, everyday conversations. Calex transcribes in real time, right on your device.

3

Get summaries

Minutes after a conversation ends, summaries, decisions, and to-dos appear — ready to act on.

Real screens

It blends into your day.

Captured conversations become summaries, to-dos, and decisions. These are real app screens.

Who it's for

So capture never becomes work.

Knowledge worker · PM
BeforeTidy notes by hand after every meeting → missed tasks, duplicate follow-ups.

Creator · Researcher

🔒
Private by design

Your conversations stay on your device.

By default, audio, transcripts, and summaries never leave your iPhone, iPad, or Mac. No Calex account, no server, no tracking. Optional cloud engines run only when you turn them on with your own key.

FAQ

Good questions.

Are all conversations sent to the cloud?
No. By default, transcripts, summaries, and to-dos are stored locally on your device. Cloud engines are used only when you add your own key and turn them on.
How are sensitive conversations protected?
You can pause listening any time, or use a schedule so it only listens during certain hours. Stored data is protected by your device's disk encryption.
Can the Calex team see my data?
By default no voice or text data is sent to any server, so it can't be accessed. There's no account and no analytics tracking.
Which devices does it work on?
iPhone, iPad, and Mac. It supports Korean and English, with widgets to check recording status and recent summaries quickly.
Does it work without internet?
Yes. Transcription and summarization run on-device, so core features work offline.

Leave the note-taking to the app.

Turn it on and Calex does the rest. Your conversations stay on your device.
