A meal. A bad night. A stressful week. A change of routine. A pain that comes back three days later. 42.2% of adults meet the criteria for at least one disorder of gut–brain interaction according to Rome V. The problem is not a lack of data. It’s that they don’t talk to each other. JOJO was born to connect these fragments. 1. You tell it about your day. “Not really in pain today, but very bloated since lunch. I’ve been stressed since the start of the week, big stakes at work. No time for exercise. Not much sleep. I tend to eat ready meals.” 2. JOJO understands and structures the information. 3. The information joins your history. 14 DAYS · ILLUSTRATION, FICTITIOUS DATA. 4. JOJO can then put this data into perspective with the previous days. Weak signals. At-risk period. Act day to day. JOJO gives you personalised recommendations. Do your ready meals often contain legumes, cabbage or onions? These foods ferment easily and can make bloating worse. Challenge: 3 breaths a day. Take 1 minute, 3 times a day, to breathe slowly. Feel better before things go wrong. Try JOJO. Available in beta.
Talking to JOJO should be as simple as talking to someone who knows you.

Discover JOJOYour AI copilot for the gut–brain axis.
JOJO is an app designed to turn everyday information into a personal memory of your digestive health.
Collect without turning your life into a questionnaire.
Natural language lets you record what is happening simply, throughout the day.
Structure.
JOJO gradually converts this information into usable data: symptoms, intensity when it is specified, diet, emotions and various everyday factors.
Connect.
The algorithm looks for temporal relationships between these data.
Personalise.
Every history is different. JOJO’s analyses therefore evolve with the user.
Anticipate.
Our R&D work aims to identify the weak signals that precede certain symptomatic periods, in order to gradually move from a reactive approach to a preventive one.
What sets us apart
A longitudinal memory
JOJO does not only answer the question of the day. It learns from the history.
A specialised AI
JOJO is developed specifically around digestive health and the gut–brain axis.
Structured data from real language
Because patients say “my stomach’s been bloated since lunchtime”, not necessarily “postprandial abdominal distension”.
An explainable approach
The aim is not to produce a black box that makes assertions. It is to be able to understand which data lead to an observation.
A prevention-centred vision
Gradually moving from “why did I have a flare-up?” to “which signals seem to herald an at-risk period?”
A bridge to the care pathway
Creating continuity between what happens day to day and what may be useful during a consultation.
Because no two guts are identical, and no two brains are alike.
JOJO is not a generic advice engine.
The more you use it, the more it builds a longitudinal picture of your daily life and your reactions: little by little, a personal memory takes shape.
Food. Mood. Body. One single story.
Our vision: to make this memory the foundation of a true digital digestive twin, able to represent each person’s uniqueness over time.

Visualise how they evolve and move beyond a simple “today I’m fine / today I’m not”.
Identify your patterns
Link diet, stress, sleep, mood, activity and symptoms.
Spot the signals that precede your difficult periods
Bring out what several weeks of data can reveal.
Act day to day
Receive information and recommendations suited to your context.
Prepare for your consultations
Get a concise overview of your history instead of trying to remember three months of symptoms.
JOJO was born from a story lived from the inside.
My name is Solenn.
In 2021, a tumour in my intestine and major surgery profoundly changed my daily life.
After the operation came chronic digestive disorders, the questions, the trials, the symptoms that change, the days when everything is fine and the ones when you no longer understand your own body.
I discovered a paradox: my body was producing an enormous amount of information, but I had no tool capable of connecting it over time.
JOJO was born from this experience.
Not to replace doctors.
Not to promise a miracle solution.
But to create what I was missing: a companion capable of building my body’s memory, helping me understand it better and turning my daily life into useful information.
