Task sharing
Share a single task with anyone — a colleague, a family member or a friend — so you both see the same task and know when it’s done. The person you invite sees only that one task: not your week, not your other tasks, not your other calendars.
Invite someone to a task
- Open the task, click the ⋮ menu in its card and choose Share task.
- Click Invite, enter the person’s email, choose Can edit or View only and click Send invite.

People you already share tasks with sit under the button as + Name — one click invites them.
They get an email invitation. Until they accept it, they show as Pending under People with access; once they accept, the task appears in their calendar.

Several people
Invite as many people as you need to the same task. Everyone sees the same task, its checklist and notes.
When the task is done
Anyone on the task can tick it off, the same way as their own tasks. The owner then gets a notification and an email, and the others get a notification.
Change access, leave or remove someone
As the owner, open Share task and use the ⋮ next to a person to switch them between Can edit and View only, copy a pending invite link, or Remove access.
Don’t need a task someone shared with you? Open its menu and choose Leave — it disappears from your calendar.
Where a shared task shows up
A task someone shares with you always lands in your default calendar — the one Tweek opens when you sign in. Looking at another calendar? Switch to the default one and it’s there. To change which calendar is the default, go to Settings → General → Default calendar.
A shared task carries a small two-people icon in front of its title, so you can tell it apart from your own tasks.

Share a view-only link
In Share task, turn on View-only link and click Copy link. Anyone with the link can open the task in a browser and see its title, date, checklist and notes — no Tweek account needed, and nothing else from your calendar. Switch it off and the link stops working right away.
Limits
You can share tasks from a calendar you own. Recurring tasks and tasks synced from Google Calendar or Outlook can’t be shared, and a shared task can’t be moved to a Someday list, because those lists are personal to each member.
Want to give someone a whole calendar instead? See Calendar sharing.
