Why it matters

Deposit disputes are won with evidence, not memory

Months after move-in, nobody remembers whether that scratch was already there. A few blurry photos and a handwritten checklist rarely settle it.

01

Unclear starting point

Without a dated record of the condition at move-in, every mark at move-out becomes an argument.

02

One-sided paperwork

A report only one side has seen is easy to dispute. A report both sides signed off is not.

03

Evidence that can be doubted

Photos can be swapped and PDFs edited. Proof is stronger when anyone can check it hasn't been.

How it works

From keys in hand to a signed-off report

A typical apartment takes about twenty minutes with a phone.

  1. 1

    Add the property

    Type, address, rooms and the other party's contact. About a minute.

  2. 2

    Photograph each room

    Follow a checklist written for your rooms, or snap everything and let AI sort the photos.

  3. 3

    Review what AI found

    Every finding is marked on the photo. Confirm, edit or dismiss it; add what it missed.

  4. 4

    Share and sign off

    Download the PDF and send a private link. The other side agrees or comments online.

AI damage detection

Damage marked right on the photo

Scratches, stains, cracks, chips and moisture are boxed and numbered on the photo itself, with location and severity. Everything outside the boxes is dimmed; inside, the original pixels are untouched.

  • Numbered markers match the findings list
  • You confirm, edit or dismiss every finding
  • Draw your own boxes for anything the AI missed

Original pixels inside every box

Only the surroundings are dimmed

Move-in vs move-out

What's new, what was already there

Compare any two inspections of the same property. Each current finding is checked against the earlier photos and classified, with the before and after evidence side by side.

  • New, worsened, pre-existing or uncertain
  • Earlier damage marked repaired or still present
  • A comparison PDF with paired photos

Online sign-off

Agreement on record, without the back-and-forth

Send a private, expiring link. The other side sees the report with every photo, no account needed, and agrees, agrees with comments, or disagrees, finding by finding.

  • Sign-off included in the next PDF

FAQ

Questions, answered

Does Bausian replace a handover protocol or professional inventory?+

It gives both sides a detailed, dated photo record with findings you've reviewed yourself, and a way to sign it off. It records visible condition only; it isn't a structural survey or legal advice.

Does the other side need an account?+

No. They open a private link, see the full report with photos, download the PDF and record their response. Links expire and you can revoke them at any time.

What if the AI gets something wrong?+

Every finding starts as a suggestion. You confirm, edit or dismiss each one, and add anything it missed, before a report is created. If photos are too dark or don't show a room well, it says so rather than guessing.

How does verification work?+

Each report has a verification code and QR code. On the verification page, anyone can drop in their copy of the PDF and see whether it's identical to the one Bausian generated. Original photos can be checked the same way.

Where is my data, and who can see it?+

Your account, photos and reports are stored in Frankfurt, Germany. For AI analysis, the relevant photos and room details (not your name or email) are processed by our AI provider, Anthropic, under EU data protection terms. Nobody else sees your reports unless you share them.

Do I need to install an app?+

No. Bausian runs in your phone's browser. You can add it to your home screen for full-screen use, and capture keeps working without signal.

How much does it cost?+

Bausian is free while in beta, with fair-use daily limits on AI analysis and reports.
