For ADHD minds · The research
Ten tabs open
is a real thing.
Tell is built around how ADHD thoughts actually arrive: many at once, fast, and loud with feeling. Here’s what the research says about that, how Tell is shaped by it, and what nobody has proven yet.
1 · Racing thoughts
Crowded,
not just dark.
“Overthinking” with ADHD is often a different thing from classic rumination. It’s less one heavy thought on repeat, more ten thoughts arriving at once. In a study of adults with ADHD, racing, crowded thoughts were their own problem, separate from mind-wandering, and they were the ones that got in the way of daily life.
What drove them most was emotion. Big feelings that swing fast are one of the most consistent findings in adult ADHD.
84 adults
Racing thoughts, not mind-wandering, predicted day-to-day problems. Emotional swings were the only significant driver.
So Telldoesn’t ask you to pick one thing to write about. You say all of it, and Tell finds the separate things inside.
2 · Getting it out
Out of your
head helps.
Moving information out of your head and somewhere else frees up room for whatever you’re doing, especially when your mind is already full. People do more of it when they’re simply told to.
Putting a feeling into words matters too: naming it calms the brain’s alarm response.
And talking skips the two things people with ADHD say make them quit journaling: the blank page, and having to organise your thoughts before you start.
Offload
Storing things outside your head improves performance under load, and being told to offload raises how much people do it.
So Tellsays it plainly: talk, don’t type. Say everything, in any order. We’ll sort it.
3 · Then sort it
A dump that goes
nowhere goes dead.
Brain dumps are popular with ADHD minds for good reason. But people who use them describe the same trap: a pile of notes that never gets reopened, or one extra step between recording and reading that quietly kills the habit.

0 extra steps
The thing that ends a dump habit is friction between saying it and getting something back.
So Tellgives something back straight away: what you said, split into tabs, so you can go through them one at a time. The loudest tab comes first.
4 · Small and practical
One question,
not a worksheet.
The best-tested talking therapy for adults with ADHD is mostly practical: planning, organising, handling distraction. Challenging thoughts is one small part of it. And the people who practised more, between sessions, did better.
Tell isn’t therapy. But it borrows the shape: short, concrete, often.
53% vs 28%
Responded to a skills-based programme for adult ADHD, compared with a support group. More homework went with more improvement.
So Tellends every reflection with one concrete question you can answer out loud or later, and parks to-dos in their own tab instead of turning them into homework.
5 · Honest AI
Not a
yes-machine.
Lots of neurodivergent people already vent to AI chatbots. When researchers read what they said about it, the top complaints weren’t about the venting. They were about the AI: it agrees with everything, it sounds generic, and it rewrites people’s words until they don’t sound like themselves any more.
55,114 posts
Across 27 neurodivergent communities. Wrong information and “very neurotypical” answers were the main complaints about AI.
So Tellkeeps your words. It highlights what actually happened, marks what’s a guess, and says so plainly instead of just agreeing.
6 · No scoreboard
A mirror,
not a streak.
Seeing your patterns over time can help, especially if you’re looking back after a late diagnosis. But tracking can also turn into pressure. In one trial of a self-tracking app with autistic adults, people got small gains, and many said the app stressed them out.
Streaks are the sharpest version of that: miss a day and the app tells you that you failed.
So Tellhas no streaks and no scores. Skip a week and nothing breaks. Patterns show the tabs that keep reopening, never “worse than last month”.
What we don’t claim
Honest about
the gaps.
Everything above is about how ADHD minds work and what helps nearby. It isn’t proof that Tell helps you, and we won’t pretend it is.
No trial has tested journaling in ADHD adults.
Not written, not spoken. Across 146 trials in the general population, expressive writing has a small average effect. Tell’s fit rests on how these minds work, not on a study of Tell.
Tell doesn’t diagnose or treat anything.
No quiz, no labels, no “manage your ADHD”. You don’t need a diagnosis to use it, which matters when so many adults are still waiting for an assessment.
It’s a journal, not clinical care.
If things feel heavy, talk to someone who can help. If you need urgent help, find a crisis line near you.
