Why this is different

Stop searching symptoms one at a time. Understand the whole system.

Search one symptom and you get one lens: a supplement, a sleep tip, a productivity hack. But your focus, energy, sleep, stress, hormones and mood are one system, and what is driving the thing you noticed is usually not where you noticed it. Every question here is answered across the whole picture at once — and every source is named, with the strength of the evidence behind it stated plainly rather than flattened into “studies show”.

  • Peer-reviewed research
  • Sleep & light
  • Nutrition
  • Movement
  • Nervous system regulation
  • Naturopathic medicine
  • Ayurveda
  • Classical Chinese medicine

Measure your nervous
system in 60 seconds.

The optional starting point, for when you would rather have a number than a question. Five questions give you a score, the one reset that fits your lowest answer, and a baseline the coach can read from next time you ask it something. Try the practice on the right first — it is the same one the library serves, and the same one the coach hands you at 3am.

Quick answer

What is PKJ?

PKJ is a holistic AI coach for ADHD, health and performance, built by Pen King Jr., a nervous system regulation coach in New York. You ask what is really driving your focus, energy, sleep, stress, hormones or mood, and instead of reducing the answer to a single lens it answers across the whole system — research, nutrition, sleep and light, movement and nervous system regulation — from four bodies of knowledge and no others: naturopathic medicine, Ayurveda, classical Chinese medicine, and peer-reviewed research on those practices, including the Nature portfolio. Each answer names the tradition it came from, states honestly whether the evidence behind it is a meta-analysis, a randomised trial or documented traditional use, carries any herb–drug interaction warning, gives no dosages, says nothing about your prescription, and ends in one of twelve free 60-second resets. Three questions a day need no account; making one adds 25 free tokens and 10 more every month. After that you pay only for what you use — a question costs 1 token, a read written from your own scores on the free PKJ Regulation Index costs 3, a pattern insight across everything you have asked costs 4, and a seven-day practice plan built from your lowest item costs 5. Packs start at $9 for 75 tokens: one payment, no expiry, and nothing renews. Your measurement history, your daily note and a clarity call with Pen are free and never use tokens. The index is an original, non-diagnostic instrument. This is coaching, not therapy, and does not replace medical care.

What's really going on

ADHD isn't a
discipline problem.
It's a nervous system one.

The focus struggles, the emotional swings, the inconsistency — they grow from one root: a system that learned long ago to run on threat and urgency instead of safety. Every productivity system you have tried sits on top of that, which is why none of them held.

You can't build steady performance on a nervous system that never feels safe. The foundation comes first — and it can be rebuilt, in small doses, on a schedule.

"You are not broken. You are contracted. And contracted energy can expand."
Why this isn’t an app

You already have the information.
That was never the problem.

Ask any chatbot how to regulate your nervous system and you’ll get a correct answer in four seconds. You’ve probably already asked. Nothing changed, because the missing piece was never the explanation. There is AI here, doing one narrow job well: reading the scores you recorded yourself and saying what moved. It never tells you anything about your body that your own measurements didn’t.

An app hands you a library. This hands you a number.

Most tools fail for one reason: they meet the wrong state. A library of two hundred practices asks you to choose while dysregulated, which is precisely the thing a braced nervous system cannot do. Here you get measured first, and then told the one practice that fits the state you are actually in. Choosing is removed on purpose.

There is no streak to break

Habit apps run on guilt: a chain you maintain until the day you miss, after which you never open it again. Nothing here counts consecutive days. The twelve resets are free and unconditional, the measurement is weekly because that is genuinely how fast this moves, and a month you skipped costs you nothing but the month.

Led by someone who had to do it

Pen spent 17 years on prescription stimulants, tapered with his physician, and rebuilt his regulation capacity over two years. Anything can summarise polyvagal theory on request. Only a person who has had to get their own nervous system back knows which week you are about to quit in.

Usage · no subscription

Pay for what you use

The coach charges a token when it writes something for you and nothing when it does not. A question costs one. A read of your own history costs three, a pattern read across everything you have asked costs four, a seven-day plan costs five. Packs start at $9 for 75 tokens, nothing renews, and tokens do not expire. A free account starts with 25 and collects 10 more every month.

What a token buys
  • 1 token — one question to the holistic coach, answered only from naturopathic medicine, Ayurveda, classical Chinese medicine and the peer-reviewed work on them, with the tradition and the evidence strength named every time
  • 3 tokens — a read written from your own weekly numbers: what moved, what didn’t, and the one thing to do about it
  • 4 tokens — a pattern read across everything you have asked, which is the thing a coach does that no single answer can. Looking at the counts is free; you only pay if you want it written up
  • 5 tokens — a seven-day practice plan built from your own lowest item, each day a named reset with a cue and a length
  • Nothing — an answer that was already written, a question this corpus cannot cover, anything with crisis language in it, and any answer that fails to arrive. You are charged when work exists, not when you press the button
  • Nothing, ever — the measurement, your score, your whole trend, the Regulation Profile, the twelve guided resets, and every read and plan you have already been given
How it actually works
  • Three questions a day with no account at all. Make one — free, no card — and 25 tokens land on it, plus 10 more at the start of every month whether you ever pay or not
  • $9 for 75 tokens, $29 for 300, $79 for 1,000. One payment each. The bigger pack is cheaper per token and that is the only difference — nothing is unlocked by spending more
  • Tokens do not expire and nothing renews. There is no monthly reset, no clock running down, and nothing in your statement next March you meant to cancel
  • Your own data is never rationed back to you. Every score, the full trend and everything already written for you stay readable with an empty balance
  • Refundable for thirty days, no questions. The tokens come off the balance in the same event that puts the money back on the card
  • And the human is free: a clarity call with Pen costs nothing and uses no tokens. The coach will say so itself when the same thing keeps coming back

The PKJ Method

What the weekly practice
is actually doing.

01

Notice Where You're Holding

Most high-performing adults with ADHD carry a chronic tension they've stopped noticing. Together we bring it into view — in the body, the emotions, the daily patterns — before changing anything.

02

Build Safety Inside Your System

With somatic practices, breathwork, and small daily shifts, we create the conditions where your nervous system can soften. Not forced calm — a real, felt sense of safety.

03

Replace Force With Steadiness

Once your system has a steadier baseline, we rebuild focus, follow-through, and emotional balance on a foundation that no longer needs pressure to hold it up.

Honest fit

Is this actually for you?

Worth being straight about, before you spend a cent.

This is for you if
  • You perform well and it costs more than anyone can see
  • Focus only shows up when something is urgent or overdue
  • You’ve tried the apps, the systems and the accountability partners
  • You’re tired of needing pressure — or medication — to feel like yourself
This isn’t for you if
  • You want a system to install once and never think about again
  • You need medical treatment — this is coaching, not therapy or psychiatry
  • You won’t show up: the practices are simple and they only work if you do them

About Pen King Jr.

I spent 17 years on stimulants before I understood what was actually wrong.

17 Years on prescription stimulants
Burnouts before finding the root
90 Days to rebuild a new baseline

Diagnosed early, handed a prescription, told to get on with it. For years it worked — elite ski racer, companies built, performance delivered. What nobody saw was the chronic tension, the emotional crashes, the inability to rest, and the quiet dread that I couldn't function without medication.

After three burnouts I worked with my physician to taper off stimulants, and spent two years rebuilding my regulation capacity from the ground up. What I built held in a way nothing before it had. PKJ Coaching exists to give other high-performing adults with ADHD what I didn't have: a guide, and a room to do it in.

What clients say
about this work.

From 1:1 coaching and nervous system coaching clients, in their own words. Individual results vary.

I stopped white-knuckling my way through every day. This work gave me a way to actually settle down instead of just pushing harder. First time in years my evenings feel like mine again.

Willy
Nervous System Coaching Client

I came in skeptical and burnt out. Working with Pen, I finally understood why I kept crashing — and had simple things that actually helped. It was the clearest my head has felt in a long time.

Claire
Nervous System Coaching Client

Working with Pen has been such a valuable experience. He has a way of holding space that makes me feel completely comfortable being honest. This often leads me to notice things I wasn't paying attention to, and the insights that come out of those moments have helped me move closer to my goals. I always leave our sessions with a clear sense of direction, and usually a new understanding of myself that I didn't have when I walked in. I've made huge strides towards my health goals, and I know I owe a lot of that to our work together.

Common Questions

Questions people ask
before they start.

Ask the coach something. The search box at the top of this page takes whatever is actually happening — waking at 3am, wired and exhausted at once, a jaw that will not unclench — and answers from naturopathic medicine, Ayurveda, classical Chinese medicine and the peer-reviewed research on them, then names one 60-second reset to run immediately. Three questions a day need no account. Make one and you get 25 tokens free, plus 10 more every month, with no card: a question costs 1 token, a read of your own scores 3, a pattern insight 4, a seven-day plan 5. When the free ones run out, packs start at $9 for 75 — one payment, nothing renews, and they do not expire. The twelve resets, the measurement, your whole history and a free call with Pen stay free either way.
You can measure how regulated yours feels, consistently — and that turns out to be the useful part. The PKJ Regulation Index asks five questions about load, recovery, sleep, body-noticing and capacity, and scores them out of 20 with a plain-language band. It is an original instrument, not a validated clinical test and not a diagnosis. What makes it worth doing is answering the same five questions once a week: a single score is only an estimate, but the direction it moves over a month is real. Nothing about it replaces medical assessment.
There is no subscription anywhere on this site. The twelve guided resets and the measurement are free to everyone, and neither needs an account. The holistic AI coach answers three questions a day with no account at all, and an account comes with 25 free tokens plus 10 more every month. After that you pay for what you use: 1 token a question, 3 for a read of your own scores, 4 for a pattern insight, 5 for a seven-day plan. Packs are $9 for 75 tokens, $29 for 300, or $79 for 1000 — one payment each, no expiry, nothing renews. Your measurement history, your daily note and a clarity call with Pen King Jr. are free and never cost tokens.
Because a general chatbot answers your question from anything it has ever read, and it sounds equally confident about a randomised trial and a wellness blog. The coach here is given a closed corpus and nothing else: naturopathic medicine, Ayurveda, classical Chinese medicine, and peer-reviewed research on those practices. It names which of the four it is speaking from, says plainly whether the evidence is a meta-analysis or centuries of traditional use, carries the herb–drug interaction warnings, and refuses to give you a dose or an opinion on your prescription. Ask it something outside that corpus and it tells you the corpus stops there rather than improvising. It also reads the scores you recorded yourself, which no chatbot has seen. A meditation app, meanwhile, hands you a library to choose from — and choosing is the thing a braced nervous system is worst at, which is why every answer here ends in one named practice, timed and cued.
PKJ Coaching is a nervous system–centered coaching practice for high-performing adults with ADHD. We work at the level of the nervous system — not task management, not habit stacking, not surface optimization. The work is forward-focused, action-oriented, and deeply personalized. It is not therapy and does not replace medical care.
Most ADHD coaching focuses on task systems, accountability, and productivity tools — all of which sit on top of the nervous system. PKJ Coaching goes underneath them. We work on the regulation capacity that makes everything else possible. The result isn't a better system. It's a regulated person who doesn't need to rely on pressure or perfect systems to function.
It can support that process — when appropriate and in coordination with your prescribing physician. PKJ Coaching helps build the regulation capacity that stimulants have been simulating, which creates conditions where gradual, medically-supervised reduction becomes more viable. This is not anti-medication. Clients always work alongside their prescribers.
PKJ Coaching is grounded in polyvagal theory, somatic neuroscience, nutritional psychiatry, and behavioral psychology. The methodology draws from established research frameworks while being adapted for practical, real-world application in a coaching — not clinical — context.
Booking a call is the 1:1 path, linked in the footer. On the call, you and Pen map what's driving your dysregulation and you leave with a clear next step — whether or not you work together. There's no pitch and no pressure. If 1:1 coaching is a fit, Pen will walk you through next steps then.
No. PKJ Coaching is forward-focused coaching that complements existing clinical support. PKJ Coaching is not medical or psychiatric treatment and does not replace therapy, psychiatry, or medical care. Pen is not a licensed therapist or medical provider.
No. PKJ Coaching is forward-focused coaching — it is not medical or psychiatric treatment, and it does not replace therapy or medical care. Therapy often works backward through history to process what happened to you; nervous system coaching works forward from where your body is right now, building the regulation capacity that lets you function without running on pressure. Many clients do both, and the two support each other well.
If you're asking that question, you're probably closer to ready than you think. The clients who get the most from this work are people who are genuinely tired of the way things have been — not looking for another system to try, but willing to do something fundamentally different. If that’s you, take the measurement first — it costs nothing, and it will tell you whether any of this is describing you.

First step

Ask the thing you keep googling.

Type it the way you would say it out loud — the exhaustion that eight hours of sleep does not touch, the focus that falls apart after a bad night, the crash that arrives at the same time every afternoon. You get one answer that looks across the whole system, every source named with the strength of the evidence behind it, and one thing to do in the next sixty seconds.
