Watermarks for Stimulus Media

What's new

Researchers can now add a participant watermark to any stimulus image or video. A toggle in the study setup overlays a unique identifier onto the media, tied to the specific participant viewing it.

Why it matters

If a screenshot gets shared outside the study, you can trace it back to exactly who took it. It works as a deterrent and a paper trail for research on unreleased or NDA-protected content.

Used for

Studies where participants are shown confidential stimulus — unreleased products, prototypes, game builds, early-stage concepts.

How to use it

When uploading a stimulus image or video, toggle on "Watermark with participant ID." Each participant sees the media with their unique identifier overlaid automatically.
