How we build
Our engineers specialize in artificial intelligence, and every one of our coaches is built through the same four-stage process.
- 01
Source the expertise
HealthAI is built on the methods of world-class coaches and leading research scientists: coaching methodology, exercise physiology and applied running science. Every one of our coaches applies it to every runner, from the 800 meters to the marathon.
- 02
Filter for quality
Generic, machine-written content is excluded at the source. Only material that reflects real expertise and current evidence is admitted, so the coach reasons from what practitioners know rather than what the internet repeats.
- 03
Keep it current
The knowledge base is maintained continuously. As the evidence develops, the coach's understanding is updated and kept current.
- 04
Give it a voice
We pair that knowledge with natural voice technology and a fully realized character, with a voice, a face, and a history, so working with the coach feels like a conversation with a person who knows the field deeply.
The HealthAI running library
Expert in every part of your running.
Every part of running, and the health behind it, built from the methods of world-class coaches and the research of leading scientists. Your AI running coach applies all of it to your training.
Our products
Six expert running coaches. One of them is yours.

How your coach works
Your coach combines expert running knowledge with the training and recovery data you share. It is not a general-purpose chatbot or a templated plan. Select a tile to learn more.
Every coach is a running specialist.
Your coach draws on a deep library of expert running knowledge and combines it with your own training and recovery data. Each coach has a voice you hear on the phone, a face you see on the site, and a personal history in the sport.
Today's session
Most running apps start from a questionnaire. Your coach starts from the training you have actually done. If you miss a session, the next one is adjusted to account for it rather than doubled up.

Meet the coaches
Six coaches. Pick yours.
Every HealthAI coach is an AI running coach, not a person. They all work from the same rules, the same research and your own training file. What changes is the name, the face and the voice you hear. You pick your coach after you join.
Running coach
Catherine Flockhart
Catherine's background is running: cross country, the track, the road, the marathon and the ultra. Pacing, easy days, and reading your file before writing a word.
Marathon and road
Kibet Langat
Kibet grew up running the red-dirt roads of the Kenyan highlands. Long easy miles, patient build-ups, and a race-day plan you can trust.
Distance running
Ethan Hale
Ethan likes the quiet miles on the coast road. Easy days easy, the work days on purpose, and patience in between.
Middle distance
Sofia Marin
Sofia comes from the track: the 800 up to the 5k. Speed with good form, and the recovery that lets you do it again.
Trail and ultra
Jack Calloway
Jack runs trails and long days in the hills. Climbing, pacing for hours, and strength that holds up late in a run.
Track and first races
Jalen Brooks
Jalen is the youngest of the crew and loves a first race. Building the habit, sharpening speed, and having fun with it.
Who our coaches are for
Every coach applies the same expert data whether you are running your first steady mile or chasing a national qualifying mark. What changes is the starting point and the detail.
Building
For runners with a race on the calendar, a time to beat, or a habit to turn into fitness. A plan periodized toward one goal and rebuilt as you train.
Competing
- A high school runner chasing a state title or a national qualifying mark, who needs structure that develops speed and aerobic capacity without burning out, with a parent or guardian's consent.
- A former collegiate runner competing post-collegiately or semi-professionally, still improving but no longer surrounded by a coaching staff.
- An athlete building toward national championships, Olympic qualifying standards, or international selection, where every training decision carries weight.
- A serious age-group or sub-elite competitor who trains with purpose and wants the reasoning behind every session.
The detail
- Athlete profiling: whether you lean toward a speed or endurance profile, read from your race times across distances, and how that should shape threshold volume, interval design, and the taper.
- Event-specific periodization from 800 meters to the marathon, supporting goal pace from below with aerobic development and from above with speed, then connecting the two in the final weeks.
- Precise intensity control: threshold and sub-threshold work, aerobic intervals, combination sessions, and the rep length and recovery that determine what a workout actually trains.
- Race execution and peaking: pacing, positioning, and tactics, with a taper calibrated to your fiber profile and how you have responded to past blocks.
Your coach works from your training data and race results, not from a self-reported label, so the plan reflects your actual level of development. Your coach does not diagnose injuries. A United States phone number identifies your account. It is never used for texts unless you opt in.
AI running coaches · Two plans
Both plans come with your coach: the same training plan, the same health portal, and the same written coaching in your portal. Text adds texting with your coach. You pick your coach after you join. One sign-in, cancel at any time.

Questions
Before you start
Are the coaches real people?
No. All six HealthAI coaches, Catherine, Kibet, Ethan, Sofia, Jack and Jalen, are AI running coaches created by HealthAI. You pick one after you join, and every coach works from the same rules, research and your own file. Each coach's face, voice and history are designed by HealthAI and do not belong to a real person, and your coach will always tell you so if you ask.
Which watches and apps work with my coach?
WHOOP and Garmin connect to your health portal in the Wearables tab, and on the Text plan you can also text your coach "connect my Garmin". WHOOP sends your recovery, sleep and resting heart rate each morning, and Garmin sends your sleep, resting heart rate, heart rate variability, Body Battery and runs each time your watch syncs with the Garmin Connect app. Your coach reads that data to adjust your plan. Apple Watch, COROS, Oura, Polar and Strava are not available yet, so with those, or with no watch at all, you log each run in your portal in under a minute and your coach plans from that.
What does it cost?
Data is $30 a month and Text is $100 a month, charged when you join and on the same date each month after that. You can cancel at any time in billing, which stops the next charge.
What happens after I sign up?
You choose a plan and go straight to Stripe checkout, where you enter your email, your date of birth and your card, and pay. Right after checkout you get an email from HealthAI with your confirmation number and a link to set your password, good for seven days, and you sign in to your health portal with your phone number. Next you pick your coach and complete your runner file in the portal. Once the file is complete, your coach writes your first 14-day plan in the background and it appears in your portal within a few minutes, and from then on you log each run there.
How do I cancel?
Open Manage billing in your health portal settings, or use the Manage billing link in any billing email. It opens Stripe's billing page, where you can cancel in a click, and cancelling stops the next charge. You can also write healthai.coach/support and we will cancel for you.
I'm new to running. Is HealthAI for me?
Our coaches are built for runners who already run regularly and have a goal in mind, from a first race to a national qualifying mark. A dedicated program for brand-new runners, built on time and effort instead of pace, is not available yet. If you are newer to running, your coach still writes a conservative plan from the running you do today, and you can ask anything in your portal.
I live outside the United States. Can I join?
Yes. Members can join from any country, prices are in US dollars, your card provider handles the conversion, and your information is stored and processed in the United States. Texting is available on US numbers for now, so outside the US the Data plan is the one to choose.
Is there an age minimum?
Yes, you must be 13 or older. Runners 13 to 17 can join with a parent or guardian's consent: at signup we ask for the runner's date of birth and the parent or guardian's name and email, and we email the parent or guardian a confirmation with a link to manage or cancel. For runners under 18, your coach never discusses weight loss or restricting food, refers any pain to a parent and a doctor.
Does my coach replace a doctor or physio?
No. Your coach is a running coach, not a clinician, and does not diagnose injuries or illness. If something hurts, your coach will tell you to see a doctor or physiotherapist and keep your training conservative in the meantime. In an emergency, call your local emergency number.
What does my coach see, and who else can see it?
Your coach sees what you share: your runner file, the runs and check-ins you log, your messages in the portal, and your texts on plans that include them. HealthAI staff can see your file to support you, and service providers such as Stripe, xAI, Twilio, Sendblue and Resend handle parts of it to run the service. We do not sell your information, and you can ask to see, correct or delete your file by writing healthai.coach/support.
What's the difference between the plans?
Both plans give you the same training plan, health portal and written coaching. Data ($30 a month) is coaching in your portal with no texts. Text ($100 a month) adds texting with your coach: ask a question or report a missed run by text, and your coach answers and adjusts your plan by text.
Where does my coach's knowledge come from?
Every coach draws on HealthAI expert data: the structured methods of world-class coaches and the research of leading scientists, which HealthAI curates and keeps current. Every training decision follows that expert knowledge and is applied to your training data, so the plan reflects both what works and where you are today.
