Part 1 of 2 · Your brainQuestion 1 of 20

Hi, I'm Ada. Tap the answer that feels most true. No wrong answers.

A dull task needs doing, like a form or a spreadsheet. How often does your attention slide off it before it's done?

Think about the last six months. Go with your gut. There are no wrong answers.

Not a diagnosis. Your answers stay in this browser.

How this test works

Two short parts, about three minutes in all. Everything runs in your browser.

  • Part 1: your brain

    Twelve questions about attention, organization, restlessness and impulsivity, plus two about when these started and how much they get in the way. They cover most of the trait areas in the official criteria, in our own words.

  • Part 2: your inbox

    Six questions about your unread count, what floods your inbox, when your brain is freshest, your colors, a quick-fire round and how you handle an “action needed” email. These build your Ada setup and your organizer archetype.

  • How we score it

    Each answer is worth 0 (Never) to 4 (Very often). A trait shows up when you pick Often or Very often, because the official criteria use the word “often.” In scenario questions, the last two choices count. Each group of six gets a band: 0 to 1 is a little, 2 to 3 some, 4 to 6 a lot.

  • How we pick the lean

    Four or more of the six attention traits leans inattentive. Four or more of the six hyperactive and impulsive traits leans hyperactive-impulsive. Both is combined. Clinicians use five of nine for adults, so ours is a rough echo, not the real criteria.

  • Your privacy

    Your answers never leave your browser. They're saved on this device so you can pick up where you left off, and “Clear my answers” wipes them. We only count that someone started, finished, saved or shared their card, copied their setup, or clicked through to sign up. If you click through to sign up, the link tells us your organizer type. Never your answers or trait results.

  • Your archetype

    Eight organizer archetypes, picked mostly from your inbox answers with a nudge from a few Part 1 patterns. It's for fun, it's the only thing you can share, and it never includes your trait snapshot.

What it covers: six of the nine attention areas and seven of the nine hyperactivity and impulsivity areas in the official criteria (one question covers both blurting out and interrupting). It skips careless mistakes, seeming not to listen, losing things, leaving your seat and running or climbing.

ADHD presentations, explained

Clinicians describe three presentations of ADHD, based on which traits show up most. The mix can change over time.

  • Predominantly inattentive

    Mostly attention and organization traits. Easy to miss, because it's quiet.

    It can look like

    • Drifting off in dull tasks or long conversations
    • Losing track of details, steps and deadlines
    • Putting off tasks that need sustained thinking
    • Forgetting appointments, bills and replies
  • Predominantly hyperactive-impulsive

    Mostly restless and impulsive traits. In adults, often more restless mind than restless legs.

    It can look like

    • Fidgeting or feeling restless when you have to sit still
    • Feeling driven, always on the go
    • Talking a lot, or finishing other people's sentences
    • Finding it hard to wait your turn
  • Combined

    Traits from both lists show up often. CDC describes both sets as equally present.

    It can look like

    • Attention and organization traits show up often
    • Restless and impulsive traits do too
    • The mix can shift as life changes

The eight organizer archetypes

Your archetype comes mostly from how you handle your inbox. It's just for fun, and it's the only part of your results you can share.

  • The Tab Collector

    Forty tabs open. All of them important.

    You save things for later, and later is a very big place. Your inbox is part library, part museum, and somewhere in there is a coupon from 2019 that's doing just fine. You're curious and you hate losing things. Fair.

    Superpower: You never lose an idea for good. Watch out for: The important email hides among the interesting ones.

  • The Deadline Surfer

    Pressure is your favorite coffee.

    You can do a week of work in one glorious night, as long as the deadline is breathing down your neck. It works, mostly. The tricky part is seeing the wave before it's right on top of you.

    Superpower: Clutch focus when it counts. Watch out for: Due dates that sneak up quietly.

  • The Idea Firehose

    Ten ideas before breakfast.

    Your brain is a party and everyone's invited. New plans, new projects, new group chats. You bring the energy to every room. The trick is catching the emails that need a reply while you're mid-brainstorm.

    Superpower: Energy and ideas on tap. Watch out for: Replies that get lost in the rush.

  • The Quiet Drifter

    Your mind takes the scenic route.

    You're thoughtful, kind and somewhere else for just a sec. Your attention drifts like a cloud, and some emails feel so heavy you'd rather not open them at all. That's not laziness. It's a brain that gets overwhelmed, and it deserves a gentler inbox.

    Superpower: Deep thinking and a big imagination. Watch out for: Heavy emails that sit unopened.

  • The Hyperfocus Diver

    Gone for six hours. Came back with a masterpiece.

    When something grabs you, the world disappears. You look up and it's dark outside, you've built something brilliant, and 47 messages are waiting. Diving is your gift. You just need someone watching the surface.

    Superpower: Laser focus on what you love. Watch out for: Everything that happens while you're under.

  • The System Hopper

    New planner, new me. Again.

    You've tried every app, notebook and color-coding system, some of them twice. Setting up a system is the fun part. Keeping it going after week three is the boring part, and boring is your kryptonite.

    Superpower: You design great systems. Watch out for: Systems that need you to keep them running.

  • The Plate Spinner

    Work, home, school, the group chat. All spinning.

    You keep a lot of plates in the air, and most days they stay up. Your inbox is where every part of life piles together: a school form next to a work thread next to a bill. You need it sorted by area, not by chaos.

    Superpower: Juggling more than most people would dare. Watch out for: One plate wobbling while you watch the others.

  • The Steady Sorter

    You've got a system, and it mostly works.

    Your inbox is under control most days, and you'd like to keep it that way without thinking about it. You don't need a rescue. You need a helper that does the boring sorting, so busy weeks don't knock you over.

    Superpower: Calm, steady habits. Watch out for: Busy weeks that knock the system over.

Questions people ask

Is this a diagnosis?

No. It's a self-check written by MailSynth. It shows which traits show up for you and which presentation your answers lean toward, but only a qualified clinician can diagnose ADHD. They look at your childhood, your health and your whole life, which no quiz can do.

Is it free?

Yes. No email and no sign-up. If you'd like Ada to run your inbox setup, MailSynth is free for 14 days with no card, then $9 a month.

Do you keep my answers?

No. The test runs in your browser and your answers never leave it. They're saved on this device so you can pick up where you left off, and “Clear my answers” wipes them. We only count that someone started, finished, saved or shared their card, copied their setup, or clicked through to sign up. If you click through to sign up, the link tells us your organizer type. Never your answers or trait results.

How accurate is it?

It's a rough guide, not a validated screener. The questions cover most of the trait areas clinicians ask about, but they're in our own words and haven't been tested in a study. CHADD warns that most online questionnaires aren't validated and shouldn't be used to self-diagnose. For a screener with research behind it, try the WHO's Adult ADHD Self-Report Scale and bring your answers to a clinician.

WHO Adult ADHD Self-Report Scale (ASRS)

What should I do next?

If the traits in your snapshot get in the way, talk to a doctor or a mental health professional. Our resource pages show how to get assessed in the US, UK, Canada and Australia, and each one lists free crisis lines if you're struggling right now.
