A secure health journal for people navigating complex and chronic conditions. This page explains what we do, what we cannot do and how your data is handled.
Every entry you log is an input. Notem reads your symptom history, detects patterns and generates a structured brief ready for your next appointment.
When you search, Notem queries five peer-reviewed databases simultaneously. Results are merged and ranked so the most relevant studies surface first.
Your health data is encrypted in transit and at rest. It is never sold to advertisers, never used to train AI models and never stored by Anthropic.
Cannot determine what condition you have
Notem does not tell you what is wrong with you. Symptom matching is for educational reference only. High match percentages do not mean you have a condition.
Cannot replace a doctor
Notem is a tool to help you organize information and communicate more effectively with healthcare providers. It is not a clinical tool and has not been reviewed by medical professionals.
Cannot prescribe treatment
Nothing on this platform is a treatment recommendation. Pattern analysis by Claude is informational only and describes what your data shows.
Cannot guarantee accuracy of AI summaries
AI-generated content including briefs, letters and research summaries should always be reviewed before use. We generate from your data but cannot guarantee every output is clinically accurate.
Security is not a marketing claim. Here is what we actually do.
All data is stored encrypted via Supabase on AWS infrastructure using AES-256 encryption at rest.
All data transferred between your browser and our servers is encrypted using TLS 1.3.
Database policies ensure no user can ever access another user's data - enforced at the database level, not just the application layer.
Your health records are never sold, shared with advertisers, insurers or any third party. Not now, not ever.
Your data is never used to train Claude or any AI model. What you log stays yours.
We follow HIPAA-conscious engineering practices in how we store, access and handle health-related data.
We do not generate research. Every result links to the original paper. Notem searches real databases using your symptom keywords - the same sources used by doctors and researchers worldwide.

5% of every Pro subscription goes directly to rare disease research. We partner with established medical research foundations that fund peer-reviewed studies into rare, complex and undiagnosed conditions.
The people using Notem are often at the end of a long road with few answers. Research funding is how that changes. We believe the business that benefits from these patients should contribute to solving their problem.
We publish charity partner details and donation amounts in our annual transparency report. We do not take credit for vague commitments. We name the foundations and report the numbers.
Free to start. No credit card required. Your first step toward getting answers.
