A real Siglo — point any camera at it

Scrolling, you've asked it too — is this the real person, or AI, or edited?

In the AI age, real gets called fake. A genuine photo, a real document, the actual you — waved away as "edited" or "just AI," and whoever made them loses the benefit of the doubt. Ensiglo is how you win that argument: seal it, and anyone can check it's really yours.

So seal what would hurt to be doubted — your work, your word, your proof. Not everything.

How it works

Seal it. Share it.
Anyone can check.

01 — SEAL

On your device

Tap once — a Siglo is added to your photo or document. Photos are fingerprinted right on your device — we never even receive them. Documents are processed to seal, then discarded — never stored.

02 — SHARE

Anywhere

Send it over WhatsApp, social or email. The Siglo travels with it, baked into the content wherever it goes.

03 — VERIFY

Free, no app

Anyone scans or uploads it and the content is checked against the seal. Genuine, or caught — in seconds.

One layer, three kinds of content

One Ensiglo — for everything worth proving.

The same trust layer, tuned to what you're protecting — your photos, your documents, and the things meant for one person only.

PHOTOS

Prove your work is really yours.

Seal a photo and anyone can check it's genuinely from you and unchanged. The moment someone edits it, the altered area is caught and boxed — free to verify, no app.

DOCUMENTS

Catch a single altered figure.

Verified strict and exact, line by line — so one changed amount is caught and pinpointed, even when every other detail looks identical. The edit a summary check would miss.

PRIVATE

Send something sensitive — with their name on it.

Encrypted on your device and opened only by the person you sent it to — whose identity is burned into every copy. We hold only the key-gate, never the file.

Seal strength

One Siglo, three levels of scrutiny.

Everyday sharing is forgiving; an original you'd defend in a dispute is not. You choose how strict the check behind the mark should be.

StandardFree

Share-proof. Survives WhatsApp, screenshots and resizing — the normal beating content takes online.

HighPro

Sharper. Tighter matching that flags finer edits a casual re-share wouldn't hide.

MaxPro

Pixel-exact. Proves the original file — catches even a single changed pixel. For artwork, contracts, originals.

Privacy

Your photos never leave your device.

"We delete it" is a promise. "We never have it" is a fact. Your photo is fingerprinted on your own device — only a one-way digest ever travels. Documents are processed to seal or verify, then discarded — never stored.

On-device fingerprint

The maths runs in your browser. The photo stays put.

One-way only

A digest can confirm a match — it can't be turned back into your image.

No honeypot

Nothing to leak, subpoena or sell. There's simply no file to hold.

What a seal proves — honestly.

Trust is built on being precise about the limits. We tell you exactly what a green check means — and exactly what it doesn't.

A seal proves

✓ It genuinely came from this sender

✓ It hasn't changed since it was sealed

✓ Tampering is caught — and located

A seal does not prove

✕ The truth of what it shows

✕ The sender's legal identity

✕ That unsealed content is fake
