The flat got cleaned the day your friend came over and sat on the sofa with her laptop.
She did not help. She did not say anything about the flat. She answered her email, and you did three weeks of dishes in forty minutes. If you have ADHD you have a story like this, and you may have thought it was a coincidence. It has a name, and thousands of people found it the same way you did.
What body doubling is
Body doubling is doing a task while another person is present, and the other person does nothing about your task.
They can be in the room or on a video call. They can be a friend, a stranger from a matching service, or a recorded person in a "study with me" video. The point is not help, advice or accountability in the strict sense. The point is that someone is there, and with someone there, the task starts.
What the research says, and how far it goes
Most people found body doubling before they had a word for it.
That is the main finding of the largest study so far, a 2024 survey of 220 neurodivergent people, mostly with ADHD, by Eagle, Baltaxe-Admony and Ringland (ACM Transactions on Accessible Computing). Its title is a quote from a participant: "It was something I naturally found worked and heard about later." People used it to start, to stay on a task and to finish, for work and for chores. The double could be present or remote, live or recorded, known or a stranger.
The same study maps body doubling on two lines. One runs from "same time, same place" to "different time, different place", which is how a recorded video can count. The other runs from quiet company, where the double barely notices you, to accountability, where they check on you. Both ends help different people.
Now the honest part. This is survey data, people describing what helped them. There is no large trial that measured it against nothing, and the theories about why it helps are borrowed from other fields and fit only partly. So we say body doubling makes starting easier, and we never say it works. It is easier. Ask anyone who has done the dishes with a friend on the sofa.
Why someone there might be enough
The best guess is that a person in the room gives an ADHD brain something it does not get from the task.
An ADHD brain does not start on importance. It starts when something outside the task makes now different from later. A deadline does that. A new place does that. Another person does that, in a very cheap way: their presence makes this minute a shared one, and shared minutes have a shape. You do not have to explain your task to them. You do not have to feel watched. You only have to not be alone with it.
That last line is why the mildest form works for so many people. A friend on mute, a library, a cafe. Company, not supervision.
How to do it
Pick the mildest version you can get today.
- A friend on a call. Both cameras on, both mics off, both working. Say what you are doing at the start and at the end. Nothing in between.
- A room with other people working. A library, a cafe, a co-working day. You are not there to talk. You are there to be near.
- A "study with me" video. A recorded person at a desk, often with a timer. Same time and place is not required; that is the survey's point.
- A matching service. Focusmate and similar services pair you with a stranger for a timed session. Good for people who need the accountability end of the line.
- A body double that lives on your screen. For the days none of the above is possible, which for most of us is most days.
Pick one, use it on the task that has waited longest, and stop if it makes you feel watched. Watched is the wrong end of the line for you. Move toward company.
What a body double on a Mac looks like
We built Timi to do the smallest thing a person on the sofa does: be there, and say the task's name.
Timi is a small pebble that sits at the bottom right of your screen while Kaapi runs. Every few minutes (five by default, and you can set it anywhere from five to sixty), Timi says one line about a real task from your list: "Have you done 'Send the invoice'?" or "Want to sit with 'Call the dentist'? I'm here." A task with steps is named by its first open step, because "do my taxes" is not something you can start and "find last year's return" is.
Three rules keep it company and not supervision:
- Timi is quiet while you work. During a focus session, while you are looking at the list, or when you have paused monitoring, Timi says nothing.
- Never a banner. Timi speaks in a small toast in the corner. The only system notifications Kaapi sends are for routines, at their time.
- Nothing is counted back. Timi never says how many times you did not answer. Each line stands alone.
Click the line and a card offers to start that task. Say "Not now" and Timi asks "By when?", and the task takes the time you pick. That is the whole intervention. It is not a person, and it does not pretend to be one. It is someone there, at the size a screen allows.
Frequently asked questions
What is body doubling for ADHD?
Body doubling is doing a task while another person is present, in the room or on a video call, without their help. People with ADHD use it to start tasks that will not start alone. The other person can be a friend, a stranger from a matching service, or a recorded person in a "study with me" video.
Does body doubling work for ADHD?
People with ADHD report it makes starting easier, and a 2024 survey of 220 neurodivergent people found most had used it before they knew the word. There is no large controlled trial yet, so the honest answer is "easier for many people", not "proven".
Can an app be a body double?
Partly. An app can do the smallest thing a person does: be visibly there and say the task's name at intervals. It cannot share a minute the way a person can. In Kaapi, Timi sits at the bottom right of the screen and speaks one line about a real task every few minutes, and stays quiet while you work.
How do I find a body double?
Start with the mildest option you can get today: a friend on a muted video call, a library or cafe, or a "study with me" video. If you want accountability, a matching service pairs you with a stranger for a timed session. If none of those is possible most days, a body double on your screen fills the gap.
