FREE BROWSER WORKFLOW

Create a screenshot proof.

Capture a browser tab or choose an image. PoF / VN records the screenshot’s SHA-256 hash in a signed proof so a reviewer can check the file they receive.

Before you continue: the screenshot and proof link are publicly accessible until the 14-day Developer retention deadline. Remove passwords, API keys, personal information, and confidential content. The notary records your submission; it does not verify that the screenshot is truthful or that work was completed.
