If you have ADHD, or a lot of the traits, you probably know the feeling. The email that scrolls off the first screen is gone. The task in the app you didn’t open today doesn’t exist. This piece is for anyone who has laughed (or groaned) at the phrase “object permanence ADHD” because it describes them a bit too well. It’s what the phrase actually means, what it looks like in my working day, and the habits that stop things vanishing on me.
What people mean by object permanence and ADHD
Object permanence is a term from child development. It’s knowing that something still exists when you can’t see it. A toy under a blanket is still there.
The ADHD community borrowed it as shorthand for “out of sight, out of mind”. It isn’t a medical term for ADHD, and nobody is saying adults with ADHD don’t understand that their keys still exist. It’s more that, unless something is in front of us, it stops taking up any room in our heads.
The NHS doesn’t use the phrase. What its list of signs in adults does include is “being easily distracted or forgetful” and “losing things often, like your wallet, mobile or keys”. I’m not a doctor, so that’s as clinical as this piece gets.
What out of sight, out of mind looks like for me
I’m dyslexic, I show a lot of ADHD traits, and I’ve never had a formal ADHD diagnosis. I wrote about that on Wednesday.
For years my filing system was open tabs and hope. If a tab was open, the idea was alive. If I closed it, it was gone, so I didn’t close them.
My brain at 9am with 20 terminal windows open is electric. My brain at 3pm is soup. And at 3pm, anything I didn’t write down at 9am has gone.
The clearest example is recent. I run a handful of AI agents for my business, and until last week each one kept its to-do list in its own file. Long, tidy files, carefully updated. I hardly ever opened them. So the things that needed me, a decision or an approval, sat in five files I didn’t read, and as far as my brain was concerned they didn’t exist. The work was fine. I just couldn’t see it.
Why “just write it down” doesn’t work on its own
Everyone says write it down. I did, for years, in lists, reminders and notebooks.
The problem is that writing something down usually moves it somewhere else you can’t see. A note in a notebook you don’t open is out of sight too. A task in a project you didn’t click into is out of sight. Five apps means five places to forget to check.
Writing it down only helps if the thing comes back to you.
What actually helps me
None of this is clinical advice. It’s what works for me.
1. One place for everything
Every extra place is somewhere to forget. So I keep cutting them. Links, screenshots, voice notes, ideas and tasks all go in the same place now, and that one place is the only thing I have to remember to look at.
2. Make the important bits come to you
I don’t trust myself to go looking. So I set things up so they come to me. When I moved my agents’ tasks into one list, anything that needs me got one tag, and that filter is the first thing I check. I wrote about how I set that up. Anything with a date goes on a calendar I actually see.
3. Save without deciding where it goes
If saving something means choosing a folder or a project first, I don’t save it, and it’s gone. Saving has to take seconds, with the sorting done later, or by something else.
4. Find things by asking, not by remembering where
I don’t remember where I put things. I do remember roughly what they were. So I search the way I’d ask a person: “what was that pricing page I saved about note apps?” If I had to remember the folder, I’d never find it.
Where Ultrathink fits
I built Ultrathink because I wanted all of the above in one place. One click in the browser, a screenshot, a voice note or a file, saved in seconds without choosing where it goes. Then an AI pass tidies it up afterwards: it fixes my spelling, writes a short summary, adds tags and picks up dates, so “chase this Friday” ends up on the calendar. When I need something back, I ask in plain English.
It won’t stop me forgetting things, and it isn’t meant to. It just means the things I save have somewhere to live that I’ll look at again.
There’s more on choosing a note-taking app for ADHD elsewhere on this blog. Ultrathink’s free plan includes the browser extension and desktop widget, and the AI part is in Pro.
If this sounds like you
If losing track of things is getting in the way of work or life, talk to your GP. The NHS has a page on ADHD in adults.
And if you’ve got a wall of tabs open right now, you’re in good company. These days, the ones that matter are saved somewhere I’ll find them again after I close the tab.
