- Prioritized Test Recommendations — Receive 4 to 8 test recommendations ranked by priority (high, medium, low), each with a plain-language explanation of why it matters.

- Recipient Tracking — Record who received your results and when, so you always know which doctors have seen your analysis.
- Report Translation — Translate your session report into any of 46 languages — including non-Latin scripts like Georgian, Arabic, and Japanese — so you can share it with doctors who speak a different language.
- Easy Sharing — Share results as text via Messages, Mail, or any app on your device — in the original language or any saved translation.

Technology
Previa uses advanced AI technology from Anthropic’s Claude to analyze symptoms and generate test recommendations. Your symptom descriptions are sent through a secure proxy server — the AI processes the request and returns structured results. No personal information beyond your symptoms is ever transmitted. All session data is encrypted and stored locally on your device using Apple’s latest data frameworks.
Perfect For
- Patients preparing for a doctor’s appointment — Arrive informed, not overwhelmed. Know which tests to ask about before you walk in.
- People who forget symptoms under pressure — The AI catches related symptoms you might overlook when sitting in the exam room.
- Caregivers managing health for family members — Run sessions for elderly parents or other family members and share results with their doctors.
- Anyone who wants to make the most of limited consultation time — A prepared patient leads to a more productive visit.
How It Works
Step 1 — Describe Your Symptoms
Open Previa and type how you have been feeling. Be as detailed as you like — when symptoms started, their severity, what makes them better or worse. The AI works best with specifics.
Step 2 — Review and Refine
Previa shows symptoms it extracted from your description, plus related symptoms you may have missed. Tap any that apply. Add your own if something is missing. The more complete the picture, the better the recommendations.
Step 3 — Get Recommendations
Receive a prioritized list of tests to discuss with your doctor. Each test includes a priority level and a plain-language reason. Save the session, translate into your doctor’s language, or share directly with your healthcare provider.
