luach
לוח · “board”, like the one on the kitchen wall

A family calendar you can talk to.

Say “dentist next Tuesday at three” and it’s on everyone’s calendar. Ask “is Saturday free?” and it answers. luach keeps your family’s days in one place, and asks before it changes anything.

  • Talk, type, or forward an email. Plain words in, the calendar updated.
  • Nothing changes without a yes. A guessed time or someone else’s plans wait for a tap.
  • Yours, at home. It runs on your family’s own server, with the AI model you choose.

How it works

The way families already talk about their week, without opening a calendar app.

1

Say it

“Swimming for Lily every Thursday at 5:30.” Type it, hold the mic, or forward the school’s email.

2

luach does the work

It works out the day, the person and the time, checks for clashes, and shows you the steps it took.

3

Sure? It’s done. Unsure? It asks.

Clear requests go straight on the calendar. A guessed time, a likely duplicate or a change to someone else’s plans waits for a yes.

What it does

One calendar for the whole household, on every screen you have.

🗣️

Talk to it

Type or speak in English, Spanish or Hebrew. Follow-ups work: “no, Thursday”, “move it to five”.

✅

Approvals

Anything unsure waits as a card with Approve and Deny, for whoever should decide.

📧

Email in, events out

Forward an invitation or a booking, or connect your Gmail, and luach proposes what belongs on the calendar.

🖼️

The kitchen board

A touch screen on the wall with everyone’s day, chores to tick, and tomorrow at a glance.

🧹

Tasks and chores

To-dos and daily chores for each person, ticked off on the board or the phone.

🔔

Reminders

A nudge before each event, tomorrow’s list in the evening, and the week ahead.

🔁

Repeating plans

School, practice, lessons: change one occurrence or all of them.

📅

Booking links

Share a page where others pick a time when the family is free.

Careful by design

A calendar is a family’s shared memory. luach treats it that way.

Run your own luach

luach isn’t a service you sign up for. Each family runs its own, on a computer it controls. If you can follow a recipe, you can do this in an afternoon.

What you need

The steps

  1. Install Docker on that computer.
  2. Get luach and copy its settings file:
    git clone https://github.com/luach-app/luach.git
    cd luach && cp .env.example .env
  3. Choose a model. Put its address, key and name in .env: a cloud provider such as OpenRouter, or Ollama on your own machine.
  4. Start it and read the one-time setup code from its log:
    docker compose up -d
    docker compose logs luach | grep -A3 "setup code"
  5. Give it a web address with https. The guide includes a ready-made setup with Caddy, which gets the certificate for you.
  6. Create the household. Open your address, enter the setup code, then invite the family by email. Install the iPhone app and type your address.

The full guide walks through every step and every optional extra, with the exact settings, backups, upgrades and troubleshooting. The source is on GitHub.

The iPhone app

The whole household in your pocket: Agenda, Board, Approvals and Ask, in English, Spanish and Hebrew.

It works with any family’s luach: enter your luach’s address when you sign in. Reminders arrive as notifications, and you can approve what’s waiting with a tap.

On the App Store soon.

Questions

Is there a version I can just sign up for?

No, on purpose. luach holds a family’s plans, conversations and, if you connect it, email. It belongs on a computer the family controls. Nobody, including us, runs one for you.

Does my family’s data go anywhere?

Your calendar, conversations and memory stay on your server. What you ask goes to the AI model you configured: if it runs at home, nothing leaves the house; if it’s a cloud model, that provider sees the request. The app shows which, and asks first.

Do I need Google?

No. luach keeps its own calendar. If your family already lives in Google Calendar, it can use that instead, and Gmail import is optional.

What does it cost?

luach is free. You pay for your own computer or cloud server, a domain, and, if you use one, a cloud AI model, typically a few dollars a month for a family.

Android?

The web app works on any phone and can be added to the home screen. A native Android app isn’t planned yet.
