Todo City Download

A private to-do app for Mac

Every task is a home.
Finish it, and the lights come on.

Todo City turns any text into a dated task — an email, a message, a web page — with an AI that runs entirely on your Mac. Then every task becomes a home in your own city, and every one you finish switches on a light.

The story

A to-do list you can see getting done.

Most to-do apps forget everything you finish. Todo City builds a city out of it.

Chapter 1

Welcome, Mayor.

Your city starts quiet and dark. Your job is to fill it with people — and the only way anyone moves in is when you get something done.

Chapter 2

Every project is a building.

Start a project and an apartment building goes up. Its sections are floors you name — “1st Floor: Travel”, “2nd Floor: Program” — and tasks on no floor live on the ground floor.

  • The older the project, the closer to downtown it stands.
  • A floor with more homes is wider; buildings narrow as they rise.

Chapter 3

Every task is a home.

A new task is an empty home with a dark window. Finish it, someone moves in, and the lights come on — and they stay on for good.

Chapter 4

Sub-tasks get a home ready.

Paint the walls, fix the boiler, hand over the keys. Tick sub-tasks off and the window glows behind the curtains. An amber window blinking? Something's overdue — someone's waiting at the door.

Chapter 5

Houses, plots and billboards.

Tasks that belong to no project are little houses at the edge of town, their porch lights on once they're done. Today's timed tasks go up on the rooftop “Moving in today” billboard.

Chapter 6

Your population is everything you've done.

Trucks circle buildings still going up. A rooftop light switches on when every home is lived in. Luxury cars come to your tallest tower. Look over the skyline at night: every lit window is something you finished.

Try it

Put up a building. Light it up.

This is a real city — turn it, zoom in, hover any window. Then start a project of your own and watch it rise on the edge of town.

Everything else

Quick to capture. Calm to plan.

Copy twice to capture

Copy any text and press ⌘C once more. The task, its date and time are filled in before you've looked up.

Dates, done right

“by Friday 3pm” becomes a deadline, “every Sunday” a repeat. When a phrase is vague, Todo City asks instead of guessing.

Today, with its hours

Your list beside the day's hours and a month calendar. Drag a task onto an hour to time it, or onto a date to move it.

Overdue, in one place

Anything whose day, time or deadline has passed gathers in one list — not a banner on every screen.

AI that never leaves your Mac

A small language model runs on your own computer. No account, no cloud, no tracking — and it works offline.

Make it yours

Pick an accent color, a 12- or 24-hour clock, the first day of your week, compact rows, and your city's sky.

Side panelDocks at the edge of your screen — even over full-screen apps.

Privacy

Nothing you capture ever leaves your Mac.

On-device AI

The model that reads your text runs locally. Your messages, emails and pages are never uploaded.

No account

There's nothing to sign up for. Your tasks live in one file on your Mac, with daily backups.

Source available

Every line is public on GitHub. Read it, build it yourself, or check what it does.

Questions

Good to know.

Is Todo City free?

Yes. Todo City is free for personal, non-commercial use under the PolyForm Noncommercial license, and its source code is on GitHub for anyone to read.

Does anything I capture leave my Mac?

No. The AI that reads your text is a small language model that runs on your own Mac, and your tasks are stored in a file on it. There's no account and no tracking. The internet is used only for the one-time model download, checking for updates (you can turn that off), and sync between your Macs if you turn it on.

How do I turn text into a task?

Select or copy any text — an email, a Slack message, a web page — and press ⌘C once more. Todo City fills in the task, its day and its time; phrases like “by Friday 3pm” become a deadline and “every Sunday” a repeat.

Which Macs does it run on?

Any Mac with macOS 11 Big Sur or later, Apple silicon or Intel. The first time you open it, Todo City downloads its AI model (about 2 GB) once.

Can I use Todo City on my work and personal Macs?

Yes. Pair them with a code and six matching digits, and your tasks stay the same on both — no iCloud or account needed. Changes are end-to-end encrypted on your Mac before they leave, so the relay that passes them along can't read them. You can keep any project on one Mac only.

Can I move my tasks from Things 3 or Todoist?

Yes. In Preferences → Data transfer, Todo City brings in your projects, headings or sections, tasks, checklists, dates, repeats and finished tasks. Things and Todoist aren't changed.

What does the city have to do with my to-do list?

Every project is a building, its sections are floors, and every task is a home. When you finish a task, someone moves in and the lights come on — so over time your city shows everything you've done.

Turn on the lights.

Free for Mac. Your first task is one copy away.
