New · Record by talking

Say it out loud. Lucka writes it down.

Tap the microphone and say what you spent. The AI turns it into records. Nothing is saved until you confirm it.

Your AI, your choice

Private on your computer or with your own key.

You set it up once, the first time you open it. You can change it later in Settings.

Your voice stays with you

Whisper turns speech into text on your computer. Always. It downloads once (about 490 MB).

AI on your computer

100% private: nothing leaves your computer. It takes disk space and a few seconds per sentence.

Or with your key

Paste your OpenAI, Claude or Gemini key. It's stored in the system keychain, never in Lucka or in backups. Only the text and your category names go to the provider.

What it does

Three answers, at a glance.

Available, for real

Income minus what you spent minus the fixed bills still to pay. From payday to payday.

Fixed bills and categories

Mark the rent as paid. See how much is left for groceries or going out.

Private by design

There's no server. Your data is a file on your computer. Export a backup whenever you want.

Your dashboard, your way

Move, resize and sort what matters to you.

Every block on the dashboard is a widget. Drag it, resize it, hide it or bring it back. To write something down: a button or your voice.

Open source

How it’s built, in 100 seconds.

A TypeScript UI in a Rust shell, a SQLite file on your disk and AI that can run offline. Every line is on GitHub.

The first time you open it

Your system will warn you. That’s normal.

Lucka is open source and doesn't pay for Apple or Microsoft certificates. So your system asks you to confirm once.

macOS

  1. Open the .dmg and drag Lucka to Applications.
  2. Open it. A warning shows up: click Done.
  3. System Settings → Privacy & Security → Open Anyway.
If you’re technical 
xattr -dr com.apple.quarantine /Applications/Lucka.app

Windows

  1. Open the installer.
  2. “Windows protected your PC” shows up: click More info.
  3. Click Run anyway.

After that it updates itself. For voice, it asks for microphone permission once.

Your money, in order and for your eyes only.
