Show HN: MedAsk – Healthcare companion for symptom guidance and doc visit prep

You wake up with a weird headache. You feel unusually tired. You notice a strange rash in a private area... Relatable? In that moment, you just want reliable answers. If you're lucky, you have a doctor in the family or live somewhere with a functioning healthcare system, but most likely you're just googling your symptoms (and getting terrified you have cancer).

We're a team of four with medical and engineering backgrounds, and we built MedAsk to help in that moment of uncertainty. Here's what it does:

- Symptom Guidance: Different from general LLMs, which overconfidently give you diagnoses with minimal information, it guides you through your symptoms using a structured approach.

- Intelligent Triage: Based on the conversation, it suggests potential next steps, from self-care to seeing a GP or seeking urgent care. Its triage accuracy is 12% better than o3*.

- Appointment Prep: MedAsk generates a clear, structured summary of your symptoms, timeline, and concerns. You can bring this to your appointment for a more focused, productive conversation. In a small pilot, 80% of users reported it improved the quality of their visit.

We're using a combination of LLMs fine-tuned on synthetic medical data plus RAG for clinical grounding. The goal is to make high-quality healthcare guidance accessible and help both patients and doctors get more out of their time together.

The assessment takes ~3 minutes. No login or personal info required. Would be grateful for the HN community's feedback. Try it here: https://app.medask.tech/
