Who makes this, and why

The problem the app is built around

A deposit is withheld for a mark on a floor. A hire company charges for a kerbed alloy two weeks after the car went back. A client says the crack in the plaster was not there before the job started. In each case both parties are describing something from memory, and the person holding the money decides.

The asymmetry is the point: whoever has a dated record wins the conversation, and almost nobody has one, because making one properly is tedious. So the app's job is not to be clever. It is to make the boring thing — a complete, dated, matched pair of recordings — take two minutes instead of twenty.

Why video rather than photographs

Photo-based condition apps came first, and a photo has an obvious weakness: it shows one angle, of one spot, chosen by the person holding the camera. The reply is always the same — what about the part you did not photograph?

A continuous walkthrough answers that. It covers the areas nobody thought to look at, it shows context around each mark, and because it is unbroken it is much harder to argue that something was left out. It is also harder to stage. That is the whole design decision, and everything else in the app follows from it: named areas so two recordings can be compared, whole-clip analysis rather than sampled frames, and reports that point back at the footage.

How the tamper-evidence works

Every recording is fingerprinted with SHA-256 when it uploads. Every exported report contains a hash covering the scans, the findings and each video's fingerprint, and that report hash is recorded on our server at the moment the report is generated. Anyone can check a fingerprint at compareai.work/verify without being shown the footage.

This is tamper-evident, not tamper-proof. Nothing stops someone editing a file; what the fingerprint does is make the edit detectable. We would rather say that plainly than let the word "tamper-proof" do work it has not earned.

What we do not claim

• The AI is an aid, not an inspector. It reads the footage and drafts the findings so you are not writing them up yourself. It is not a survey, a valuation or a professional inspection, it can miss damage, and it can describe damage that is not there. Review it before you send it to anyone.
• A report does not decide a dispute. No court, insurer, landlord or hire company is obliged to accept it. What it does is move the argument from assertion to evidence.
• The guides are not legal advice. Deposit rules, carrier liability, hire contracts and policy wording all differ by country and often by state. We write about how to make a good record, not about what your rights are.
• We do not pretend the record is neutral. You choose what to film. A walkthrough is strong evidence because it is continuous and dated, not because it is objective.

Your footage

Recordings live in a private storage bucket scoped to your account, and links the app generates to play them expire after an hour. Videos are analysed by Google's Gemini API when you ask for an analysis — recording alone does not send anything to a third party. Videos are deleted automatically once they pass your plan's retention window, 30 days on the free plan and 12 months on Pro, and you can delete your account and everything in it from inside the app.

The full detail, including who our processors are, is in the privacy policy. We do not use advertising identifiers, we run no analytics or crash-reporting services, and we do not sell data.

The company

BioAxiz Pte. Ltd. is a software company registered in Singapore. CompareAI Inspect is listed on the App Store under that name; the app is free to download, with an optional Pro subscription that raises the monthly analysis allowance and extends video retention.
