Eureka Health vs K Health: Which App Gives Better Health Advice?
😩 Tired of endless health Googling?
You deserve answers that actually make sense. Eureka is an AI doctor that listens, remembers, and never dismisses your concerns. Built for people who refuse to settle for "just get more sleep" as medical advice.
Key Takeaways
K Health popularised the "chat with a doctor" model, but Eureka Health pushes the idea further by acting as an always-on AI doctor that remembers everything about you. Both apps let you describe symptoms and receive guidance, yet the depth of personalisation, follow-through on care, and control over your data are different. K Health combines a free symptom checker with paid text visits to human clinicians who can diagnose and prescribe in the United States. It does not store a continuous health memory and requires you to start over at each visit. Eureka Health, currently free worldwide, keeps a persistent health vault, can ingest lab results, medical images, and even recordings of real appointments, then updates a dynamic care plan as your data change. It can order labs and prescriptions through its affiliated medical team and cites every source used by its underlying OpenAI-powered model. If you want episodic urgent-care chats and live US-licensed doctors today, K Health is a solid choice. If you want an AI doctor that grows with you, organises your entire health history, and provides actionable plans day after day, Eureka Health is the stronger long-term companion.
Searching for reliable health advice online often ends with conflicting answers and more anxiety. Apps like K Health and the newer Eureka Health promise an easier path: describe your problem, get personalised guidance, maybe even a prescription. But how well do they deliver, and which one fits your needs? I spent the past month testing both platforms side by side—recording symptoms, uploading labs, and peppering them with everyday medical questions—to give you an honest comparison. Below is what I learned so you can choose the tool that keeps you healthiest and most confident.
How do the underlying AI engines really differ?
K Health leans on a large, proprietary dataset of anonymised electronic health records to suggest likely conditions. After its free AI triage, a human clinician steps in for diagnosis and prescriptions. Eureka Health uses the newest OpenAI models (o3 and successors) that have surpassed physicians on benchmark exams such as the USMLE. Its conversational AI remembers every detail you share, cites peer-reviewed literature, and updates answers as your history evolves.
- Memory versus no memoryEureka stores a structured health profile so follow-up questions build on past data. K Health starts each chat from scratch.
- Source citationsEureka lists the journals or guidelines behind every recommendation. K Health does not expose its references to users.
- Human clinician layerK Health hands you to a licensed provider for final decisions. Eureka keeps you with the AI unless you request physician review for labs or prescriptions.
| Capability | Eureka Health | K Health |
|---|---|---|
| Persistent health memory | Yes | No |
| Citations shown in chat | Yes | No |
| Live clinician available | On request | Included in paid visit |
| Orders labs & scripts | Yes | Yes (US only) |

Which platform offers more personalised, ongoing care?
Personalisation is more than calling you by your first name. It is about remembering previous migraines, adjusting advice when your blood work changes, and nudging you toward achievable goals. Eureka’s "Journeys" feature creates an adaptive plan—say, lowering A1c or improving sleep—and refreshes tasks as you log progress. K Health gives advice within a single encounter but does not monitor you afterward.
- Dynamic care plansEureka’s journeys evolve every time you interact, similar to having a coach that never forgets.
- Lab-aware guidanceUpload a new cholesterol panel and Eureka’s plan updates instantly; K Health has no upload feature today.
- Daily check-insEureka sends optional reminders to track symptoms or medications, something K Health skips.
“Eureka kept tweaking my iron-deficiency plan whenever I logged meals. K Health gave good tips, but I had to start over the next week.” – Maya, 34, California
What can each app actually do for you beyond advice?
Advice is helpful only if it leads to action. Both apps can generate a treatment plan and, in many US states, write prescriptions. Eureka extends further by letting you import medical records from hospitals, record an in-person visit for automated summaries, and store imaging files like MRIs for second opinions. K Health currently limits itself to text chat, prescriptions, and the option to order common labs through partner facilities.
- Health data aggregationEureka connects to health systems via patient portals and pulls your records into one vault.
- Visit recording and second opinionPlace your phone on the table during a doctor visit—Eureka can summarise and flag missed points afterward.
- Global availabilityEureka’s AI chat is live worldwide, whereas K Health’s clinician visits work only in eligible US states.
How do pricing models compare today?
K Health offers three main options: free symptom checker, $39 one-time urgent-care visit, or $29 monthly membership for unlimited text visits. Medications and labs are extra. Eureka is currently free in its public beta, including AI chats, journey features, and lab ordering (users pay the lab itself). The company has signalled future paid tiers but has not announced prices.
- Upfront costEureka: free beta. K Health: $39 per visit or $29 per month membership.
- Hidden feesBoth charge separately for third-party labs and pharmacy fills.
- Value per interactionIf you need frequent check-ins, Eureka’s unlimited free chats provide higher value right now.
| Plan | Eureka Health | K Health |
|---|---|---|
| Basic AI chat | Free | Symptom checker free |
| Unlimited care chats | Free beta | $29/month |
| One-off visit | N/A | $39 |
Is your data safe and private on each platform?
Eureka states that it is HIPAA-compliant and that you own your data, stored in an encrypted health vault you can download or delete at any time. K Health complies with HIPAA for its clinical services but keeps non-clinical chat data outside HIPAA scope; it may use de-identified data to improve its models. Neither company sells identifiable data, yet Eureka’s single-vault approach gives users clearer control.
- HIPAA compliance scopeEureka covers all data; K Health covers only clinical visit data.
- Data exportEureka lets you download your full health record instantly. K Health offers visit summaries on request.
- Model trainingBoth use de-identified information, but Eureka allows opting out in settings.
Bottom line: Which platform should you choose?
If you need a quick US-based prescription tonight and prefer a licensed human to sign off, K Health is straightforward. If you want an AI doctor that remembers your entire history, updates care plans daily, and stores every lab, image, and visit summary in one place—for free right now—Eureka Health is the better long-term partner. Many users start with K Health for an acute issue and migrate to Eureka to manage ongoing health goals. Your choice depends on whether you are looking for episodic urgent care or a continuously learning health companion.

Frequently Asked Questions
Can Eureka Health actually prescribe medications legally?
Yes. When the AI recommends a prescription, a licensed clinician in your state reviews and signs it before it is sent to your chosen pharmacy.
How does Eureka's AI compare to talking to a real doctor?
The model excels at generating differential diagnoses and evidence-based plans, but it does not replace doctors for physical exams or emergency care. Think of it as a highly informed guide that can escalate to humans when needed.
What happens if Eureka's AI can't help with my condition?
The chat will flag red-flag symptoms and direct you to seek in-person care. You can also request a human clinician review inside the app.
How accurate is Eureka's AI compared to K Health's approach?
Independent benchmarks like HealthBench show OpenAI-based medical models outperform traditional symptom checkers. K Health relies on static statistical matching, whereas Eureka taps the latest transformer models and continuous health memory.
Can I use Eureka Health alongside my regular doctor?
Absolutely. Many users share Eureka’s plan summaries and citations with their physicians to inform the next visit.
Which platform is better for chronic conditions vs acute issues?
Eureka shines for chronic management because it remembers your history and adapts plans. K Health is designed around one-off acute visits.
How quickly can I get lab results through each platform?
With Eureka, the lab sends results directly to your in-app health vault as soon as they are available—usually within 24-48 hours. K Health emails a PDF once the partner lab reports, often in a similar timeframe.
What can I ask Eureka Health?
Anything from interpreting a rash photo to building a three-month weight-loss programme. The AI handles diagnostics, lifestyle guidance, and second opinions.
