A Real-Time Shared To-Do List, Right in Your New Tab

Shared to-do lists usually break in the same place: someone edits their copy, someone else edits theirs, and by the afternoon nobody knows which version is right. What you actually want is one list that everyone sees at once, updating the instant anyone changes it — no refreshing, no “which file is latest,” no pasting screenshots into chat. And you want it somewhere you already look, not buried in yet another app.

Here is how to run a real-time shared to-do list right on your Chrome new tab, so your team stays on the same page without adding a tool anyone has to remember to open.

Why a real-time list beats a static one

A static shared list — a doc, a spreadsheet, a screenshot — is a snapshot that starts going stale the moment you send it. Live collaboration fixes that: when a teammate ticks off a task or adds a new one, you see the change as it happens. There is no merge step and no version confusion, because there is only ever one list. That is the difference between a list people trust and a list people quietly stop checking. If you are new to keeping tasks on the new tab at all, start with adding a to-do list to your Chrome new tab and then bring in the people you work with.

How to set up a shared list your team can edit live

1. Install Slaet from the Chrome Web Store — it is free, and you can also open it as a web app at app.slaet.space.
2. Sign in with Google. An account is what lets a list live across people and devices, so this step is required for collaboration.
3. Create a list, add your tasks, and share it with your teammates. Once they open it, everyone edits the same list and every change shows up live.

From then on the list sits on each person's new tab. When one person checks something off, it is checked off for everyone — no message needed to say it is done.

Share a single task without giving away the whole list

Sometimes you do not need a collaborator, you just need one person to see one thing. For that, Slaet lets you share a single task as a read-only link. Whoever opens it can view the task and its details but cannot edit it — and, importantly, they do not need an account or a sign-in to view it. It is the quick way to hand off a spec, a request, or a status to a client or a colleague outside your team, without pulling them into the full list.

Give each task the context it needs

A shared list is more useful when tasks carry their own detail, so people are not asking “what did you mean by this?” in a separate thread. In Slaet every task has room underneath for rich-text notes — the brief, a link, the acceptance criteria. You can set reminders in plain language like “follow up Thursday at 10am” and get a notification, and flag the few items that are genuinely high priority so they stand out to everyone on the list.

Shared lists beyond work: groceries, trips, projects

Some lists are only useful when someone else can see them too: the grocery list your partner adds to on the way home, the packing list for a trip you are planning together, a small project that needs two people pulling the same way. A group chat is a running log, not a list. Items scroll away, get repeated, and nobody knows what is still outstanding — which is how someone ends up buying the milk twice. A shared list is a single source of truth: check something off and everyone sees it gone. The gain is biggest on the boring, recurring stuff — groceries, chores, packing — where the cost of a duplicated or forgotten item is small but constant.

Keep one list per part of life — Groceries, Japan trip, House, work — and share each with only the people who need it. Lists hold notes as well as tasks, so the packing list can carry a note about what still needs buying. Reminders written in plain language bring time-sensitive items back up.

Use the same list across Chrome, Brave, and Edge

Most of us use more than one browser: Chrome on the work laptop, Edge on the office desktop, Brave at home. A list written in one browser is invisible in the others, so the task you jotted down this morning is missing when you sit at a different screen this afternoon. All three run Chrome extensions, so the same install works in each. Open a new tab, sign in with Google, and repeat the sign-in on your other browsers and devices with the same account — each one now shows the same tasks and notes. You can also reach everything from the web app at app.slaet.space in any browser.

Solo use stays private and offline

Collaboration is opt-in. If you are just managing your own work, Slaet is local-first: your tasks live in your browser, work fully offline, and need no account at all. Signing in unlocks sync across Chrome, Brave, and Edge and the ability to share and collaborate — but until you choose to share something, your lists stay yours. Because local data lives in one browser, a different browser starts with a clean slate until you sign in — so on a shared or work computer where you would rather leave nothing behind, simply stay signed out. Once sync is on, the shared copy is stored on Supabase, tied to your account. Slaet never reads your browsing history and never sells your data, and you can delete anything you have shared, or your whole account and its synced data, at any time and go back to local-only use.

Frequently asked questions

Is the shared to-do list really free?

Yes. Slaet is completely free — unlimited lists, tasks, notes, reminders, sharing, and live collaboration, with no paid tier and no credit card.

Do my teammates need to sign in to edit the list?

To edit a shared list live, yes — sharing across people and devices runs on an account, so each collaborator signs in. Viewing a single task you've shared as a read-only link needs no account at all.

Do I need an account just to use it myself?

No. Solo use is fully offline and local to your browser with no account. You only sign in when you want to sync across devices or collaborate with other people.

How fast do changes show up for everyone?

Changes are live — as a teammate adds, edits, or completes a task, you see it happen. There is nothing to refresh and only ever one version of the list.

Can I share a list without the other person installing anything?

For a full live list, both people use it. For a one-off, share a single task as a read-only link that anyone can open with no account or install.

Which browsers can I sync between?

Chrome, Brave, and Edge. Sign in with the same Google account in each and your tasks and notes follow you.
