Study Guardian

Body doubling, without the double

Body doubling — working while another person is present — is one of the most reliably reported focus strategies in the ADHD community. It isn't about supervision; it's that being seen quiets the part of your brain that wanders off. The catch: it needs a person. A friend with matching free hours, a stranger on a video call, a busy café.

Study Guardian is an experiment in keeping the "being seen" without the "someone seeing": your own webcam senses whether you're at the desk, your PC notices which app is actually in front, and at the end of a study block you see how it really went. No partner to schedule, no camera feed leaving your machine, no one to perform for on a rough day.

Why the mechanism can survive without a person

What many people describe in body doubling isn't the double's opinion — it's the ambient awareness of being observable. In one 2024 study of 220 neurodivergent adults, a large majority reported meaningful task-completion improvements from body doubling; practitioners describe the effect as externalizing accountability. A camera that notices you left, and a session score you'll see afterward, externalizes the same thing — with the difference that the "observer" here is a process on your own computer with no memory of your face.

Built for the rough days, not just the good ones

It's not a replacement for people

If human body doubling works for you — a friend, a Discord study room, Focusmate — keep it. Many people run both: a person when they can get one, the private version at 1am when they can't. (We wrote an honest comparison with the human option: Focusmate vs. the private version.)

Study Guardian is a focus tool, not a medical product, and nothing here is clinical advice. It ships presence-only webcam sensing in the current beta and says so in the app.
