Early access Opening to our first travelers soon

The trip planner that stays on the trip.

Forward your bookings, drop in the screenshots and links you've saved. rbyn turns them into a day-by-day plan — and quietly re-plans it when the train runs late, it rains, or the museum is closed.

Nothing gets booked or paid without your tap.

The problem

A trip lives in fourteen tabs and one tired person's head.

Planning tools stop being useful the moment you leave home. Everything that actually goes wrong happens on the road — and that's exactly when nobody is helping.

INBOXFlight, hotel and train confirmations, each in a different format and time zone.
CAMERA ROLLScreenshots of cafés, maps and a menu you can't read.
SAVEDReels, blog posts and a friend's list of “must-dos” with no addresses.
ON THE ROADA delay, a downpour, a Monday closure — and a plan that no longer works.
How it works

Bring the mess. Leave with a plan that adapts.

Drop in everything

Forward confirmation emails to your trip address, share screenshots and links, or just describe what you want in your own words.

rbyn builds the days

It reads every booking, checks opening hours and travel times, respects your pace and budget, and lays out a realistic plan — with the reasoning visible.

It travels with you

When something changes, rbyn notices first, proposes a fix, and drafts the messages. You approve with one tap — or ignore it.

Features

Small things, handled.

Inbox to itinerary

Confirmation emails become timed, located entries — with check-in windows and cancellation deadlines pulled out for you.

Live re-planning

Delays, weather and closures trigger a revised day, not a red alert. You see what changed and why.

Group trips without the group chat

Everyone adds their must-dos; rbyn finds the plan that fits the most people and flags the trade-offs.

Point, and understand

Photograph a menu, a sign or a ticket machine. Get a plain-language answer, plus the phrase to say back.

Budget that keeps score

Bookings and receipts roll into one running total, in your currency, split however your group likes.

Offline day packs

Each morning, the day's plan, maps, addresses and tickets are saved for when the signal isn't there.

Built on Claude

An agent that reads, reasons, and asks before it acts.

rbyn is built on Anthropic's Claude models. We chose Claude for careful long-document reading, reliable tool use, and the judgment to say “I'm not sure — here are two options” instead of guessing.

long context

Reads every confirmation, policy and fare rule for the whole trip at once, so nothing contradicts anything else.

vision

Understands screenshots, maps, menus and handwritten notes.

tool use

Calls transit, maps, weather and venue-hours services to check that a plan is actually possible.

agent loop

Watches the trip, decides when something matters, and proposes a revised day for you to approve.

How we build it

Helpful, not pushy.

You stay in charge

rbyn proposes; you decide. It never books, pays or sends a message on your behalf without an explicit tap.

Shows its work

Every change comes with the reason behind it and the source it checked, so you can trust it — or overrule it.

Your trip is yours

Booking emails and photos are used to plan your trip, not to sell you things. Delete a trip and its data goes with it.

Your next trip, with a co-pilot.

We're building rbyn now and will open it to a small group of travelers first. Tell us where you're headed and we'll be in touch.
