Your own work, with the date inside it

The first capture of something you made: the finished piece, the details and the stages in between. Every photo carries Content Credentials, and an independent service timestamps the file, so the date does not rest on your word.

Where it goes wrong

Who had it first?

A copy turns up

Someone posts your design as theirs. The question becomes who had it first, and when.

Dates are easy to change

The date in an ordinary photo file can be edited in seconds.

The stages disappear

Sketches and in-between versions show your hand, and they are rarely kept together.

What to capture

The piece, the details, the stages

The Progress template in the app has an overview and details. Make a file at each stage, and the timestamps show the order.

Content Credentials (C2PA) travel inside each photo and record which app and which device made it.

How it goes

Shoot, close, send it on

01

Capture as you make

The first sketch, the stages and the finished piece, each in a file of its own or together.

02

Close the file

An independent service timestamps the series. The date these captures existed is then fixed.

03

Keep it, or send it when asked

The file stays on your phone until you share it as a report, an archive or a link.

At the other end

What anyone who asks sees

They open the file in the browser, with no account and nothing to install: the photos, which app and device made them, and the time from an independent service.

The file establishes
  • That these captures already existed in this form at the time of the timestamp
  • That they were signed with a key that Apple or Google attests was made in the secure hardware of this phone, for our app
  • That an image added, removed or changed since then, or a change in the order, shows up
It leaves to someone else
  • That you designed it: the file only shows that it was captured with this device
  • Who owns the rights
  • That nobody made something similar earlier
The verification page in the browser: this file checks out
Questions

What people ask

Does this give me copyright?

No. The file does not grant or register any right. It records when these photos existed and which app and device made them.

What are Content Credentials?

An open standard (C2PA) that stores provenance data inside the file: which app, which device, and the time according to the device.

Can I show one photo without sharing the rest?

A single photo from the archive names its place in the series and the photo before it in its manifest, but not whether the series is complete: the verification page verifies only its own Content Credentials, and only the whole file shows that it was in the sealed series, under its timestamp. So share the report, the archive or a share link.

Does it work for digital work?

It records what the camera sees. For a design on a screen the photo shows the screen, and a photo of a screen is still a photo.

Record it the day you finish

Basic has no subscription, and your first file is free, with the same seal as Plus.
