An Offline To-Do List for Your Browser — No Account Needed

Most to-do apps ask for an email before they let you write a single task. It feels backwards: you wanted to jot down “buy milk,” and instead you are creating an account, verifying a link, and handing your list to a server you know nothing about. If you have ever wanted a to-do list that just works — offline, in your browser, with no sign-up — this is for you.

Why “no account” matters more than it sounds

Requiring an account does two things, both bad for a quick-capture tool. It adds friction at the exact moment you want zero friction, and it means your tasks and notes leave your device before you have decided you trust the app. For anything sensitive — work notes, personal reminders, a half-formed idea — that is a real cost. A tool that works locally first flips the default: your data is yours until you choose otherwise.

How a local-first to-do list works

Slaet is local-first by design. When you install it, your tasks and notes are stored in your browser and work fully offline — on a plane, on spotty Wi-Fi, or on a machine you never sign in on. There is no account step and nothing to configure. You open a new tab and start writing.

Cloud sync is available, but it is opt-in. If you sign in with Google, Slaet keeps a synced copy so your workspace follows you across Chrome, Brave, and Edge. Until then, nothing leaves your device — and you can delete your account and all synced data at any time.

What you can do offline

Working without an account does not mean working with less. Offline, in local mode, you still get the full workspace: tasks with context, rich-text notes, reminders with browser notifications, priority flags, and your own wallpaper. It is the same tool described in the guide — just with your data staying put. If you are setting this up for the first time, start with how to add a to-do list to your Chrome new tab.

Who this is for

A local-first, no-account to-do list suits anyone on a shared or work computer, anyone who works offline often, and anyone who simply prefers that their notes stay on their own machine. It is also the fastest way to try a new tool honestly — you find out whether it fits your day before you commit anything to a server.

Frequently asked questions

Can I really use a to-do list with no account?

Yes. Slaet works immediately with no sign-up, storing everything locally in your browser. An account is only needed if you later want to sync across devices.

Does it work with no internet connection?

Yes — it is local-first and works fully offline. Your tasks and notes are available whether or not you are online.

Where is my data stored?

By default, in your browser's local storage on your device. If you choose to sign in, a synced copy is stored on Supabase tied to your account, and you can delete it whenever you like. Slaet never reads your browsing history and never sells your data.
