AI can fake any photo in seconds.

Captured, not generated.

Photos used to settle arguments. Now anyone can generate or edit one that looks just as convincing. Captilo proves that a photo was taken by a camera: when, where, on which device, and that nothing has changed since. Anyone can check it, without having to trust us.

A long scrape along the door sill of a white car, captured with Captilo on 4 October 2026 — Captured with Captilo. Shown as a display copy with a sign blurred; the record belongs to the original file.

A photo on its own proves nothing.

AI can generate a photo, and its date can be changed in seconds. When a claim, an inspection or a handover is disputed, what counts is whether anyone can check where a photo came from.

Privacy-first architecture

Private by design.Verifiable without us.

Your photos stay with you. The proof is public.

If our servers were breached

Your photos stay on your phone.

We never receive your photos, names or locations, so there is nothing to steal. A photo leaves your phone only when you share it.

If Captilo disappeared

Your proofs outlive us.

Every proof is recorded publicly. Anyone can check a certificate, even if Captilo no longer exists.

Where a photo has to hold up

Captilo is built for the moment someone later asks whether a photo can be relied on.

Property & rentals
“Was the damage there at move-in?”
Landlords, tenants and agents record condition at handover with photos neither side can quietly backdate.
Construction
“Was the membrane in before the slab was poured?”
Site teams document hidden work while it is still visible, with time and place signed on the spot.
Insurance claims
“Was this photographed where and when the claim says?”
Claims teams receive photos that carry their own time and place, recorded at capture.
Field monitoring
“Did the monitor actually visit the site?”
Third-party monitors and NGOs submit visit evidence with a recorded place and time.
Supply chain
“What state was the shipment in at handover?”
Every handover point adds a proof that is hard to dispute later.
