Living with Hashimoto's often feels like a guessing game. Flare-ups happen without warning. Diet, stress, sleep, and lab results all matter - but tracking them across endocrinologist visits, supplement bottles, and meal photos on your phone is exhausting. Hazel is built for the work between appointments.
WHAT HAZEL DOES
- Ask Hazel anything, by chat or voice. Your AI companion knows everything you've logged: meals, supplements, labs, symptoms. It surfaces patterns you'd miss, like "your last three brain fog spikes came after low-sleep nights".
- Track symptoms and supplements in seconds. Log fatigue, brain fog, mood, body pain, and the supplements you take, with reminders that fit your routine.
- Snap your meals. Hazel identifies what's on your plate and learns which foods correlate with how you feel over time. Built for AIP, anti-inflammatory, and gluten-free patterns.
- Log your labs. TSH, T3, T4, anti-TPO, free T4, and antibodies - visualized over time so you can see whether your treatment plan is actually working.
- Doctor-ready reports. Export a clean PDF summary of your last 90 days - labs, symptom trends, interventions tried - to share with your endocrinologist or functional medicine doctor.
- Tools for the journey. Guided meditation, NSDR (Non-Sleep Deep Rest), and educational content rooted in published research.
HOW IT WORKS
1. Log daily - symptoms, meals (photo or manual), supplements, sleep. Takes under a minute.
2. After a week, Hazel surfaces what's trending better and what needs attention.
3. After three months, your labs and lifestyle tell one story - and you can share it with your doctor.
WHO HAZEL IS FOR
Hazel is for the person who has been diagnosed with Hashimoto's thyroiditis or sub-clinical hypothyroidism and wants to do the lifestyle work alongside their medication - the AIP diet experiments, the supplement protocols, the stress management, the patient self-advocacy. If you've ever sat in a doctor's office trying to remember what changed since your last lab draw, Hazel is for you.
