Your clerk walks the property with a phone. Every photograph is sealed
where it is taken and joined to the inventory line it answers — so the report is drafted
before they are back at the desk.

How the record is made
One sheet, printed in four passes.
PASS 01
The walk lays the keyline.
A 94-item checklist in inventory order. Photographs attach to the item they answer, not
to a camera roll somebody sorts on Friday.
Room instances, so a three-bedroom flat records three bedrooms
“Could not locate” is a recorded answer, never a blank
PASS 02
Each photograph is sealed where it is taken.
A fingerprint, the time, and who held the phone. Nothing is renamed, cropped or quietly
replaced afterwards.
Capture timing is disclosed on the report, never enforced
Retakes are counted and printed, never silently replaced
PASS 03
The baseline is joined, line by line.
Joined on the checklist item, not on similarity. So “was that there when they moved in?”
is a question the sheet has already answered.
Move-in and move-out on the same row
Unpaired photographs are counted and shown, never absorbed
PASS 04
A person signs it off.
Drafts wait. Nothing issues itself, and no document leaves Walkbook until somebody at
your agency has put their name to it.
Every drafted sentence is editable before approval
Issued versions are frozen and reproducible years later

SAMPLE DATA · NOT A REAL PROPERTY OR TENANCY
Move-in vs move-out
The question a deposit turns on, answered on one row.
The same mark, two years apart. Drag the line.
Move-out · 29 Jul 2026 · claimed against the deposit
Move-in · 12 Aug 2024 · already recorded, tenant-signed
Both sides are the same drawing on purpose. The mark is identical —
what changes is who recorded it, and when. That is the whole argument.

What we actually measure
One detector is measured. We print the figure.
Anything a tool claims to see in a photograph should arrive with a number
attached. Here is ours — and what it does not cover.
Bathroom · clean / needs cleaning
AUC 0.903 95% CI [0.814, 0.969]
Measured on 26 dirty and 30 clean photographs
Shown one dirty photograph and one clean one, how
often does it rank them the right way round. One detector, one room — everything else
below is what we do not yet claim.
01Everything else is filing, pairing and queueing.
02Other checks are internal triage only — they never write a word in your report.
03Fair wear is a human judgment. Walkbook drafts language, never a verdict.
04Smells, boilers and alarms are invisible to any camera. Your clerk decides those.
05Photographs are never sent to a third-party AI service.
What comes out
Two documents. The second is why agencies stay.
Most inspection software stops at the report. The deposit is decided by
what comes after it.

Questions
The five things agencies ask first.
Do we have to stop using what we use now?
No, and we would rather you did not. The pilot runs beside your current process
for two or three checkouts, on the same properties, so you can compare the output against
work you already trust before anything changes.
Who takes the photographs — our clerk, or the tenant?
Either. Every photograph records who held the phone, and the report says so
plainly. A tenant-signed capture reaches a higher evidential tier under mydeposits Scotland
rule D9.1, by the scheme's own written rule.
What happens when the clerk cannot find something?
“Could not locate” is a recorded answer with its own line in the report, not a
gap. A missing item that reads as silence is how a coverage argument gets lost later, so
Walkbook states it instead.
What does it cost?
The walkthrough is free and carries no obligation. Subscription pricing
is being set with the first pilot agencies rather than guessed at in advance — so if
you are one of them, you help set it. We will not quote you a number we have not
decided.
Where does our data live?
On a single UK-region host we control, encrypted at rest and in transit, under
a signed provider agreement. Photographs are never sent to any third-party AI service —
that line does not move.
