Intelligent thyroid health tracking
Production-grade digital health application built on a Retrieval-Augmented Generation (RAG) architecture.
The system combines curated medical documentation with user-specific health data to deliver personalized, context-aware support. During onboarding, users share information about their condition, treatment status, and decide which data they want to provide, maintaining full control over their privacy from the start. This allows the assistant to focus exclusively on the user’s specific thyroid condition.
The LLM-based assistant leverages the user’s historical data to interpret patterns and changes over time. Combined with endocrinology-focused knowledge, the system can help surface early signals compatible with flare-ups, imbalances, or pre-thyroid phases that may warrant closer attention.
Vector search dynamically retrieves relevant lab values, symptoms, and historical context, ensuring responses are grounded in the user’s real data rather than generic medical information. The assistant operates within strict safety boundaries: it interprets, explains, and contextualizes information, but does not provide diagnoses or treatment recommendations.
Designed for long-term monitoring, Thyro helps users track and organize thyroid-related data over time, supporting continuity between medical visits and extended periods of self-management.

What it is
Thyro is a native mobile application designed to support people living with thyroid conditions by centralizing lab results, symptoms, and health signals into a single intelligent system. Through longitudinal analysis of this data, it can help identify early signals compatible with thyroid alterations, even in phases where no formal diagnosis has yet been made.
Who it is for
Thyro is built for individuals managing long-term thyroid conditions, as well as for digital health teams exploring patient-facing products where AI-supported data interpretation adds value without replacing clinical decision-making.
The problem it solves
Thyroid conditions often evolve gradually, while medical appointments may be spaced months apart. During these gaps, subtle symptom changes, lab variations, or lifestyle patterns can be overlooked or hard to recall. Thyro brings this information together and supports pattern interpretation over time, helping surface early signals that may indicate relevant changes and enabling more structured medical follow-ups.
Why it matters
Managing thyroid health is a long-term, data-intensive process. Thyro shows how pattern interpretation in health data, supported by artificial intelligence, can help individuals better understand their personal evolution, reduce data fragmentation, and improve continuity between daily life and clinical care.

Hello Marina, how are you feeling today?
Can you explain my latest TSH results?
Your latest TSH from January 15, 2024 is 3.1 mIU/L, which is within the normal range (0.4-4.0 mIU/L). Good news - this is actually lower than your August reading of 3.5, showing improvement. Your levels have been stable around 3.1-3.5 over the past few months, and you're doing well managing your Hashimoto's. Keep tracking and we can monitor any changes together!
Lab report analysis (PDFs & images)

AI & data architecture
Thyro uses artificial intelligence as an interpretation support layer, not as a clinical decision-maker. The assistant relies on a RAG architecture combining curated medical documentation with user-specific data.
Vector search dynamically retrieves relevant lab values, symptoms, and historical context, enabling longitudinal pattern analysis while keeping responses grounded in real user data.
The assistant does not provide diagnoses or treatment recommendations. Its role is to interpret, explain, and contextualize existing information to support medical follow-up.
Security & privacy
Thyro is designed from the ground up to handle sensitive health data. All data remains user-owned, securely stored, and accessed only with explicit consent.
The product is progressing through formal information security and quality certification processes, reinforcing a rigorous approach to data handling and system design. AI behavior is clearly constrained, and no automated health decisions are made.
