Introducing Slots

Not every day needs a timetable. A day can now hold open time slots beside your fixed commitments, so you can say “2–4pm, around Shibuya, something relaxed” without inventing a time you never meant.

09:30

Flight to Tokyo NRT · Terminal 1

Around Shibuya 2h

Dinner · Ichiran Booked · #4821

One day, two fixed commitments, one open slot. The dashed card is the slot: it holds an intent and a shortlist, not an appointment.

Loose, time-optional planning
Pull candidate places into a slot from your trip’s shared list, star the ones you want, and rank your top picks. Decide when you’re actually standing there.
Butter proposes and fills
Ask Butter to shape a blank trip into slots you edit before anything is filled, or fill a single slot on demand with ranked suggestions. It never invents a time and never commits you to a place. You accept the ones you like, one by one.
Reminders that stay honest
Because a slot isn’t an appointment, reminders and the Today card stop treating placeholder times as real. No more 9:00 AM you never meant.
Invite a client
A client sees the trip overview and the full itinerary, and never sees expenses, settle-up or trip settings. Ideal when you’re planning a trip for someone else. Under Members & sharing.
Sharper AI planning
Suggested activities land on the right real-world place far more often, and a plan that hits a snag now retries itself instead of giving up.

Share the trip, not the spreadsheet

Butter Agent grew up: a built-in idea generator, a real map, a shared checklist, and trip cards worth posting.

Butter Planner
A built-in AI trip-idea generator that drafts a first itinerary for your destination and dates, which you then edit.
Interactive trip map
Explore the whole itinerary geographically instead of reading it as a list.
Social Studio
Turn a trip into a shareable card in three designs: countdown, live, or recap. Post it to your story, send it in chat, or save it to Photos.
A new Wallet
A fresh Wallet tab with the expense list grouped by day, so a week of spending reads at a glance.
Shared to-do list
One checklist for bookings and packing that the whole group can see and tick off.
Faster, everywhere
Screens load instantly from cache, and pull-to-refresh always brings in the latest.

1.0.0 Apr 2026

Hello, Butter Agent

The first public release. The trip planner that replaced our own group’s shared spreadsheet.

Trip wizard and day-by-day itinerary
Set destination, travel dates and currency in minutes, then read the whole plan as a clean, scrollable day view.
Group expenses in any currency
Log spending as it happens, with automatic exchange-rate conversion.
Fair split and settle up
Split equally or by custom amounts, then settle the whole trip at the end.
Flights and accommodation
Bookings tracked in one place, alongside the plan rather than buried in email.
Guest mode
Try the whole app without signing up, and upgrade to an account any time.
English and Thai
Full bilingual support throughout the app, not just the marketing.
