Chronicler

Transcription that
never leaves your Mac

Drop a recording into the window and a minute later it is text. Not just a transcript: a summary with decisions and tasks, a readable version and a verbatim text with timecodes. Your Mac does the work on its Neural Engine — no account, no subscription, no cloud.

Three moves

Nothing to set up: the app lives in the menu bar and waits for you to hand it a recording.

01

Hand over a recording

Drag a file into the window, drop it onto the menu bar icon, or forward a voice message to your own Telegram bot. Any format: mp3, m4a, wav, mp4, mkv, webm, ogg.

02

Get on with your day

An hour of audio takes about a minute. You can close the window — the queue keeps going, and the menu bar icon shows how much is left.

03

Read the text

A recording opens on its summary: what it was about, what was decided, who does what. The verbatim text is one click away, for when you need the exact words.

Three texts per recording

All three are produced once, during processing, and all three are kept. Switching between them is instant — nothing is recomputed and nothing is sent anywhere again.

Summary

Opens first. What people almost always want is the answer to “what was this about”, not forty minutes of text.

DECIDED 04:12
Release moves from the 4th to the 18th of August, demo on the 11th.

Readable

The same speech without fillers, slips and false starts, broken into paragraphs. The version you can forward to someone.

Let’s start with the sync. The product catalogue still isn’t finished: some items arrive with no units of measure.

Verbatim

The raw model output with per-word timecodes — for quoting and for checking against the audio.

What it looks like

The window opens from the menu bar — though on an ordinary day you never need it.

Bot. Who wrote in, who is allowed, what has already arrived.

A Telegram bot on your own computer

Forward a voice message to the bot and get the text back. No static IP, no port forwarding, no domain: the bot lives inside the app and works as long as your Mac does.

Access is granted, never assumed

You can’t type in someone’s @username — until their first message the bot doesn’t know it. They write to the bot, you get a prompt with “Allow” and “Decline”.

The owner isn’t chosen silently

Whoever writes first is a candidate, not the owner: someone could have found the bot by name before you did. The app shows who it was and asks.

Nobody is left in silence

A stranger is told their request went to the owner; if declined, that access wasn’t granted. Otherwise they’d keep sending voice messages into the void.

Why this matters

Transcription services ask you to upload the recording of your meeting. This one doesn’t ask.

The audio stays here

The recording is transcribed on your Mac. It is not sent to any server — ours or anyone else’s. The app doesn’t even keep the audio: the source file stays where it was.

Works without the internet

The network is used twice: once to download the recognition model, and every few hours to ask for the latest version number. The summary is a separate, optional feature.

You can check for yourself

The source is open under the MIT licence: what the app does with your recordings is visible line by line, not taken on the developer’s word.

Installing

No account, no installer: open and drag. Two minutes, and most of that is downloading the model.

  1. 1

    Open the disk image and drag to Applications

    Double-click the downloaded file, then drag the app into the Applications folder.

  2. 2

    Launch it and wait for the model

    On first launch it downloads the recognition model — 461 MB, once. The system then spends about half a minute compiling it for your machine.

  3. 3

    Drop in your first recording

    Any file: mp3, m4a, wav, mp4, mkv, webm, ogg. Or straight onto the menu bar icon — no need to open the window at all.

macOS will warn about an unidentified developer

The app is signed but not notarised by Apple — that is a paid process and hasn’t been done yet. It takes two clicks to open, and only the first time: right-click the app → “Open”, then “Open” again in the warning dialog.

A double-click won’t do here: the system offers only “Cancel”. After that the app opens the ordinary way.
