HealthAI · Catherine Flockhart, AI running coach
Frequently asked questions
Straight answers about how Catherine coaches, what it costs, and what happens to your training data.
Is Catherine a real person?
No. Catherine Flockhart is an AI running coach created by HealthAI. Catherine's face, voice and history are designed by HealthAI and do not belong to a real person, and Catherine will always tell you so if you ask.
Which watches and apps work with Catherine?
Today Catherine works from the runs you log in your health portal, which takes under a minute per run. Automatic sync from watches and apps such as Garmin, Apple Watch, Coros or Strava is not available yet. If you wear a watch, read the distance, time and effort from it and log the run, and Catherine plans from those.
How does the free trial work?
Every live plan starts with 2 days free. Your card is saved at checkout and the first monthly charge happens when the trial ends, unless you cancel in billing before day 3. We email you about a day before the first charge. Each person gets one free trial, so a repeat signup starts at the full monthly price.
What happens after I sign up?
You enter your email and date of birth, then pay or start your trial in Stripe checkout. 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 complete your runner file, either in the portal or on an onboarding call with Catherine on Accountability. Once the file is complete, Catherine 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 caroline@henry.biz and we will cancel for you.
I'm new to running. Is Catherine for me?
Catherine is 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, Catherine 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. Coaching calls are 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, Catherine never discusses weight loss or restricting food, refers any pain to a parent and a doctor, and calls only between 7am and 9pm local time.
Does Catherine replace a doctor or physio?
No. Catherine is a running coach, not a clinician, and does not diagnose injuries or illness. If something hurts, Catherine 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 Catherine see, and who else can see it?
Catherine sees what you share: your runner file, the runs and check-ins you log, your messages in the portal, and your calls or 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 caroline@henry.biz.
What's the difference between the plans?
Every plan gives you the same training plan, health portal and written coaching. Data ($30 a month) is coaching in your portal, Text ($100 a month) adds texting with Catherine, and Accountability ($200 a month) adds two coaching calls a day at times you choose, plus calls whenever you need them.
Where does Catherine's knowledge come from?
Catherine 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.
