Frequently asked questions

Juno is a 24/7 AI health assistant built for people living with chronic illness. Chat by text or voice any time — get emotional support, feel heard, and log symptoms as they happen. Juno spots patterns over time and turns messy day-to-day data into clean summaries you can take to your doctor.

Juno is built for life with chronic illness. Insights from thousands of patients and input from hundreds of doctors shape how she asks questions and responds. She keeps your symptoms, treatments and day-to-day context together, helping you find relevant patterns and prepare for appointments.

Juno uses a curated knowledge base of medical journals and trusted sources such as Mayo Clinic and Mount Sinai, with doctors helping shape the information and responses. Patient experiences, including what people share online, can suggest practical questions to explore; they are not treated as medical evidence. Juno brings this information together with your own context. She supports your care and does not replace your clinician.

By voice or text, whichever feels easier.

Daily check-ins give the best results, especially if you're using symptom tracking or medication tracking — those work best with a steady rhythm. That said, it's entirely up to you. Juno is there whenever you need her.

Juno can support the full range of long-term conditions — from autoimmune conditions like lupus, rheumatoid arthritis and IBD, to chronic pain conditions like fibromyalgia and endometriosis, to complex and rare conditions like ME/CFS, POTS, Ehlers-Danlos and mast cell activation syndrome. If you're living with it day-to-day, Juno can help.

You can keep a symptom history when you have more than one diagnosis. Record what happened, when it happened and how it affected your day, including uncertainty about the cause. A symptom record does not establish which condition caused it; discuss that with your clinician.

No. Many people use Juno while they work with their clinicians toward answers — Juno turns scattered notes into structured records and summaries you can bring to appointments, and gives you the language to advocate for the care you need. Juno itself doesn't diagnose conditions or tell you what your symptoms mean — only a qualified clinician can diagnose you.

You can log symptoms manually or describe how you feel to Juno by voice or text. Review the saved symptom, date and severity so your history reflects what you meant. Symptom tracking is available without a paid membership; free AI conversations are limited.

Juno looks at what you share in chat alongside sleep, activity and wearable data, plus environmental factors such as weather, temperature and pollen. She helps you notice what changes together, from a flare after a short night to less obvious patterns over time. These are clues to explore with your care team, rather than proof of a cause.

You can review your recorded symptom history in the app. For appointment preparation, check the report feature in your app for availability and any requirements, then review the report before sharing a PDF with your clinician.

Yes — Juno integrates with 20+ wearables and health platforms, including Apple Health, Fitbit, Oura, Garmin, Whoop and more. Sleep, heart-rate, activity and recovery data flow into your timeline automatically.

Yes. We never sell your health data. It is encrypted in transit and at rest, stored on secured servers in the United States, and protected by strict access controls. We use HIPAA security protocols as a benchmark. Our AI agreements prohibit using your health data to train models. Eligible AI requests use zero data retention (ZDR); coverage depends on the provider, feature and endpoint, and legal or safety exceptions can apply. ZDR does not cover every Juno service. Saved history, files, memory, backups and technical diagnostics have separate retention rules. See our Privacy Policy for details.

On encrypted servers in the United States. We honor GDPR and UK GDPR standards for our EU and UK users, along with applicable US privacy laws. Whether HIPAA applies depends on the service and healthcare relationship. We protect your data with encryption, strict access controls, and contracts that prohibit our AI providers from training on your health data. See our Privacy Policy for the security safeguards and retention rules.

Our AI providers do not use your conversations to train their models.

No — Juno can't replace your doctor. She's a tool that works alongside them, in parallel: making your doctor's life easier and your life easier at the same time.

You choose what to share. You can email your Juno summary or doctor letter, or print a PDF to bring to an appointment. Direct access through a doctor portal is not available yet; we are working on it.

Juno has completed an initial internal medical evaluation involving 36 doctors and plans further studies. This initial evaluation does not make Juno a replacement for your clinician.

Juno combines medical research with our founders' work at the University of Oxford and UCL, lived experience of chronic illness, and our own internal studies. We use this work to test and refine how Juno interprets health information and generates responses, with the aim of improving medical accuracy.
