Previa

Previa helps you get more out of every doctor's appointment. Describe how you're feeling, and Previa's AI identifies related symptoms you may have overlooked and suggests tests worth discussing with your doctor. Already have results? Import a lab or imaging report and Previa explains it in plain language. No diagnoses. No prescriptions. Just better preparation. WHY PREVIA * Most people forget symptoms under pressure, struggle to describe them clearly, or leave appointments wondering if they asked the right questions. Previa gives you a structured, AI-assisted way to organize your health picture before you walk in - so you and your doctor can make the most of your time together. * Reviewed by an experienced MD advisor to keep Previa's information clear, safe, and appropriately scoped. * Lab and imaging reports are written for clinicians, not patients. Import a photo or PDF of your report and Previa explains what it means in plain language, along with the questions worth raising at your appointment. HOW IT WORKS * AI Symptom Analysis: Step 1 - Describe your symptoms. When they started, how severe they are, what makes them better or worse. The more detail you provide, the better the analysis. Previa identifies what you reported and suggests related symptoms you may not have considered. Anything it can't interpret is shown separately. Step 2 - Review AI suggestions and select any additional symptoms that apply. Add your own if something is missing. Step 3 - Receive a prioritized list of 4 to 8 tests to discuss with your doctor, each with a plain-language explanation of why it may be relevant. * Understand your test results - in plain language, with a list of things to discuss with your doctor. KEY FEATURES * AI symptom analysis powered by Anthropic's Claude * Prioritized tests to discuss with your doctor (high, medium, low) * Plain-language explanations of your lab and imaging results, with what to ask your doctor * Full support for 8 languages: English, Spanish, French, German, Italian, Polish, Russian, and Ukrainian * One credit covers a symptom session or a test explanation - your first two credits are free * iCloud sync - your sessions, results, reports, and profile follow you across your devices * Session history to track symptoms and past analyses * Report translation into 46 languages, including Arabic, Japanese, and Georgian * Recipient tracking - record which doctors received your results and when * Profile-aware analysis - age, biological sex, known conditions, and medications PRIVACY FIRST Previa requires no account, no email, and no sign-up. Your data is stored on your devices and syncs only through your own private iCloud - we never receive a copy. Face ID or Touch ID is required on every launch. No advertising. No analytics. No tracking. You can delete all your data at any time from Settings, and deletions reach your other devices. For better symptom analysis tailored to your situation, symptom text is sent along with Profile context you've filled in - age, biological sex, known conditions, and medications - through a secure proxy server, to the AI. Your name is never sent, and any Profile field you leave blank is simply omitted. When you use Test Results, the report you import is sent to be read and explained. You can hide any sensitive information on the report before importing - the explanation doesn't depend on it. Our proxy server keeps nothing after the request is processed. Anthropic deletes requests within 30 days and never uses them to train its models. IMPORTANT Previa is a health preparation tool, not a medical diagnostic tool. It does not provide diagnoses or medical advice, and does not prescribe treatments. Always consult a licensed healthcare provider for medical decisions.
