For everybody going on the trip
Right up until it's spread across a group chat, four tabs and somebody's notes app, and nobody's sure which hotel got booked. Renku keeps one plan that everyone on the trip can edit. Your own AI agent can edit it too, and you'll always see which of you moved the museum.
01 / As worked out as it is
Nothing makes you fake certainty about the part of the trip nobody has got to yet. A city with nothing under it looks like a city with nothing under it.
02 / Days you can look at
Every day is drawn to scale, so a 90-minute train takes up 90 minutes. Two bookings that overlap show up in red before anyone reads the times.
03 / Changes, before you make them
Move three nights from Lyon to Nice and the damage is counted first: which days move, and what's already booked that you don't get back. Make it anyway and History puts it back.
04 / Bring your own agent
Hand it a key and it edits the real thing, under your name with an agent tag beside it. Every version is kept, so if it moves the wrong day you put it back exactly. That's what makes it safe to let everybody edit.
It doesn't find you hotels and it doesn't book anything. It's the plan itself — the part everybody has an opinion about.
