Good questions

Everything you might ask.

The honest rundown: what it is, how you start, what it costs, what happens to your data, and where it stops and your doctor begins.

The basics

What Joize actually is.

What is Joize?
A nutrition and longevity coach that lives in your texts. Snap a photo of your plate, ask anything, set a real goal, and get coached by something that remembers you between conversations. No dashboards to maintain, no logging chores. You text the way you would text a friend who happens to know a lot about food and your body.
Is this a real coach, or AI?
It is AI, and we would rather say that plainly than dress it up. It has serious nutrition and longevity knowledge, it remembers your goals and patterns and what you ate on Tuesday, and it answers the second you text, every day. Credentialed human nutritionists are on the roadmap for when you want to go deeper on something specific.
Do I need to download an app?
No. Coaching happens entirely in iMessage. There is a companion app for people who like seeing the day laid out, and it is what connects Apple Health, but the coaching never requires you to open it.
Does it work on Android or WhatsApp?
SMS works anywhere, so Android is covered for coaching. WhatsApp is built and waiting on approval from Meta rather than on us, so it is not live yet. When it is, you will be able to move the thread over without losing your history.
What can it actually do?
Read a meal from a photo and give you calories, protein and the one change worth making. Find a restaurant near you and tell you what to order. Read a blood panel and explain it in plain language. Remind you about supplements at an hour that suits you. Remember your history so the coaching compounds instead of resetting. And check in on you, without being asked.
Can I pick its personality?
Yes. The default is warm, steady and encouraging. You can ask for blunter, drier or louder if that is what actually gets you moving. Every voice drops the act the moment something real comes up: a worrying lab, a hard day, a question that needs care rather than banter.
Getting started

Starting, paying, leaving.

How do I start?
Text the coach. That is the whole signup flow. If you would rather start on the web, sign up here and it texts you first.
Is it free?
Coaching starts free in chat. You can talk to the real coach, photograph a meal and ask questions before money comes up at all. If it is not for you, you walk away having paid nothing.
What does it cost?
Coaching starts free. Coach is €19.99 a month (or €159 a year) and Performance is €49. Every plan starts with a 7-day free trial, and founding member prices are lower and stay locked for as long as you keep the subscription. See the plans.
Is there a free trial?
There is no time-limited trial to forget to cancel. Instead the coach is genuinely free to use until you decide to subscribe. You are charged when you pick a plan, and it renews at that price each period until you cancel.
Can I pause instead of cancelling?
Yes. Travel, a busy stretch, a break you need. Say so in the chat and we will sort it out. We would rather you come back than churn.
What about refunds?
Handled through Stripe and in line with your consumer-protection rights, including the EU right of withdrawal. If something went wrong, text us and we will make it right.
Your data

Handled like it matters.

Is my health data safe?
We treat it as sensitive because it is. Joize is operated by Joize FlexCo in Austria and runs under the GDPR, which means enforceable obligations about how your data is stored, used and protected rather than a promise on a landing page. Read the health data notice.
What do you do with it?
We use it to coach you. That is the entire list. It is not sold, and it is not used to train anyone else’s model. The details are in the privacy notice.
Do I have to consent?
Yes, and we ask plainly. Explicit consent for health data comes before any coaching starts. No buried checkbox, no coaching that quietly begins before you agreed. If you do not consent, we do not coach.
Can I export or delete everything?
Anytime, and quickly. Ask the coach for an export and you get your data. Ask it to delete you and it deletes you. Leaving should be as easy as joining.
Will it message me when I have not asked?
Only with your consent, and only at a cadence you control. Proactive check-ins are a real part of why it works, but one message turns them down or off, and there are no streaks or guilt mechanics anywhere in the product.
The medical line

Where coaching ends.

Is this medical advice?
No. Joize gives general nutrition and wellness guidance. It is not medical advice, diagnosis or treatment, and it is not a substitute for your doctor. When something looks clinical, whether a worrying lab, a symptom or a medication question, it drops the act, gets careful, and tells you to run it past a qualified professional.
What if something feels urgent?
Contact a doctor or your local emergency number, not a text thread. The coach will say the same thing, immediately, rather than trying to handle it.
Can it work alongside my doctor or dietitian?
That is the best version of it. Bring what they told you into the thread and the coach will work inside those constraints, including medication interactions and conditions it should not be improvising around.

Still curious? Ask it directly.

The coach will answer questions about itself as happily as questions about dinner.
