Koe

Just talk — your plans and notes fall into place.

  • Say "dinner tomorrow at 7" — Koe creates the schedule
  • "Share with my crew" — Koe knows your friends, groups, and the nicknames you use
  • Ask anything — Koe searches the web too

Choose who sees each plan and note

Family, friends, groups — switch the audience to match the moment.

Schedule

Choose who to share each event with. Family schedules for family, friend plans for friends.

  • Mix groups and individuals (e.g., family + one close friend)
  • Each event gets its own chat — coordinate without losing context
  • Reminders and recurring events keep nothing slipping through
Schedule

Note

Share shopping lists, trip plans, and more — with whoever you choose. Or keep it just for yourself.

  • Edit lists together in real time — no more out-of-sync grocery lists
  • Folders to keep family notes and friend notes apart
  • Lock private notes so only you can open them
Note

Chat

Chat directly on each schedule and note. Manage all your groups in one place.

  • Tap a schedule or note to open its chat — never lose the thread
  • Group with friends-of-friends without exchanging contacts
  • Reactions, pins, and unread badges for quick check-ins
