Listing photo
Paris loft
14 to 27 September. Checked in today.

A 60-second photo check when you walk in, time-stamped and shared with your host, so nobody argues later.

A quick prompt appears when you open your check-in instructions.
2
Check
Six taps from the listing's own amenities, and a photo per room. Sixty seconds.
3
On record
Saved, time-stamped and sent to your host. Nobody can change it later.

Checkout Coming soon: the same check at checkout, so any claim compares before and after.

The problem

A heads-up at check-in, not a refund three days later.

Most check-ins end at the lockbox. After that, it's up to the guest to notice, take photos, message the host and report within 72 hours. Many report late, or never.

Nobody records how the place looks at check-in.
Guest
Finds something dirty, broken or missing. Can't prove when.
Host
Finds damage or missing items. Can't prove when.
Platform
Decides without evidence. Every case costs support hours and money, often a refund too. Both sides leave unhappy.
Who it's for

One record. Three sides of the door.

How it works

Sixty seconds, and both sides see the same thing.

The arrival sheet: Check-in Check, is everything as listed?

The arrival checklist with a flagged dishwasher and four room photos
Six taps, a photo per room

Evidence

Guests and hosts already take photos on their own. What's missing is a shared record.

1 in 4 Reddit dispute posts mention photos, video or proof, up from 1 in 5 in 2018.

No tamper-proof record
A guest staged photos for a claim; a ten-year Superhost quit.
Host · 2026
No clear process, all ad hoc
The host had records the alarm worked; the guest still got $7,000.

Hard to share with support
Fighting a damage charge, a guest couldn't upload some photos.

Hard if you're not tech-savvy
Photograph, upload, message the host, report within 72 hours.

For platforms

The support line AI can't reach.

AI is cutting the cost of each contact: call-centre costs fell $15M in H1 2026. Refunds and credits for bad stays rose $14M. A check at the door cuts the contacts, and the refunds that follow.

$1.33B
The largest platform's operations and support bill in 2025, about $2.50 per night booked
$40–65M
a year saved at 3–5% of that line
$200M
a year in damage cover: 10% of ~100M stays buy it at $20
$240–265M
a year in total. Low case (2% saved, 3% attach): about $85M
Known: Airbnb 10-K FY2025, 10-Q Q2 2026. Assumed: 3–5% saved, 10% attach, $20 per stay. A pilot replaces the assumptions with data.
Uses the trigger you already have. The prompt hangs off the check-in event fired when a guest opens the arrival instructions.
Every check is a data point. Amenity by amenity, a photo per room, the outcome. It shows which listings match their description.
Why now
AI fixes contacts, not disputes.
Support AI deflects simple contacts but can't settle a dispute where the facts are missing.
Vision models can check each amenity.
Checking from a photo that the dishwasher is there and intact is now cheap and instant.
Damage protection needs evidence it doesn't have.
It promises protection to both sides, but every claim relies on evidence gathered after the fact.
For guests

The check is free, always. Plus a few things guests didn't have before.

Fixed, not refunded
Your host hears about it straight away, while it's easy to fix.
No awkward message
We tell your host for you.
Damage cover
Optional cover for accidental damage, backed by your check-in record. Break a glass, not your holiday.

Why I built this

An awkward message I didn't send at first. Then an early departure and an afternoon of back-and-forth with Airbnb.

In September 2026 I checked into a flat in Stockholm. It hadn't been cleaned and the dishwasher didn't work. For three nights I didn't send the message, because asking a stranger to send a cleaner and fix a dishwasher felt awkward. When I finally did, it turned into an early departure, an afternoon of back-and-forth and emails with Airbnb support, and a partial refund. I had photos, but it was my word against the host's. It was the third time this had happened to me this year.

Each one was a fix on day one that became a refund on day three. Sixty seconds at the door, with the host told automatically, would have changed all three. That is Check-in Check.

FAQ

Questions people ask first.

Is Check-in Check part of Airbnb, Booking.com or Vrbo?

No. It's an independent concept, designed as a feature any rental platform could add.

What happens if I skip the check?

The place is treated as matching the listing on arrival; you can still report through the platform within its window.

Will guests actually do it?

It's their protection: report now, or lose the refund later. It's opt-in and takes 60 seconds; skip it and there's no cover. And hosts change first, because knowing any guest may check is enough.

How is this different from photos in the chat, or the platform's damage protection?

Photos in chat are one-sided and sent after the fact. Host cleaner apps are host-only. Damage-protection claims come after the fact, and inventory reports are built for long lets. Check-in Check is the only record made at arrival and shared by both sides.

Who sees my photos?

Only you, until you send the record to your host. Everything in the demo is deleted automatically after 24 hours.

Does it cost anything?

The check is free for guests, always. Damage cover is optional.

What if the host disagrees with my record?

You both have the same time-stamped record, so the platform decides on evidence, not guesswork.

Which platforms does it work with?

Any short-term rental platform: Airbnb, Booking.com, Vrbo or direct bookings.
