Asha vs ChatGPT: which medical AI is right for you?
ChatGPT is a brilliant general-purpose assistant. Asha is a medical-specific AI with peer-reviewed citations on every answer, architectural refusals on prescription requests, and a physician-founder team. For health questions, Asha is the tool built for the job.
TL;DR
ChatGPT (GPT-5.5) is the most versatile consumer AI on the market. It writes code, summarizes documents, drafts essays, and answers casual questions across nearly every domain. For medical questions specifically, it has known limitations: no architectural guarantee of evidence grounding, no enforced refusals on prescription requests, no curated medical corpus, and reported hallucination rates that climb when the web search tool is not invoked. Asha addresses each of those points directly. Asha is built by two board-certified physicians, grounds every answer in a curated medical corpus (PubMed, OpenAlex, PMC, StatPearls, DailyMed, FDA, clinical guidelines), and refuses prescription, dosing, and diagnostic requests by design. Both tools have a place; Asha is the right tool when accuracy of medical information is the priority.
Side-by-side comparison
| Feature | Asha|AI | ChatGPT (GPT-5.5) |
|---|---|---|
| Built for | Medical questions | General purpose (code, writing, search, images, video) |
| Evidence citations on every answer | Yes, citation-grounded by architecture | Optional via SearchGPT; off by default in casual chat |
| Medical corpus | PubMed, OpenAlex, PMC, StatPearls, DailyMed, FDA, clinical guidelines (126M+ knowledge vectors) | General web training data; web access via SearchGPT |
| Sacred medical refusals (prescriptions, dosing, diagnosis) | Architecturally enforced | Soft-guarded; can be elicited by phrasing |
| Built by | Two board-certified physicians (DNAi Systems) | OpenAI engineering teams |
| HIPAA posture | PHI anonymization, zero retention from AI provider, BAA-covered Vertex AI Gemini backbone | Not a HIPAA-covered entity; Business/Enterprise tiers offer data privacy |
| Hallucination rate on medical queries | Bounded by retrieval-augmented architecture and refusals | 9.6% with web access, 47% without (per GPT-5 PMC analysis) |
| Multilingual medical context | Multilingual via Gemini 3 with medical context | Multiple languages (general) |
| Voice mode | Voice input and output | Advanced Voice Mode included |
| Document analysis | Upload labs, imaging reports, clinic notes | Unlimited file uploads (Plus tier) |
| Audit trail per answer | Every citation is verifiable and clickable | Conversation history only; sources may be summarized |
| Code generation | Not the focus | Best-in-class (Codex, Agent Mode) |
| Free tier | 100 queries/month free | Free with usage caps |
| Paid tier | Asha Pro: $14.99/mo or $9.99/mo (billed annually); 30-day free trial | Plus $20/month, Pro $100-$200/month |
When to choose ChatGPT
ChatGPT remains the broadest, most capable consumer AI assistant in 2026. Choose ChatGPT when:
- You need help writing code, drafting documents, brainstorming, or solving general knowledge problems.
- You want a single tool that handles dozens of unrelated tasks per week.
- You are using Deep Research, Codex, Sora video, or Advanced Voice on non-medical topics.
- Your medical question is casual (general curiosity) and you plan to verify with a clinician anyway.
- You already pay for Plus or Pro and want to centralize tool use.
When to choose Asha
Asha was built for the moments when the answer to a medical question actually matters. Choose Asha when:
- You want citations to real, peer-reviewed studies on every answer.
- You are checking drug interactions, reading lab results, or researching a new diagnosis.
- You expect the assistant to refuse prescription, dosing, and diagnostic requests (which is the safe default).
- You want the conversation grounded in clinical guidelines, FDA labels, and primary medical sources rather than web summaries.
- Privacy of your health information matters and you want a tool designed for that posture.
- You need medical context in a language other than English.
Specific use cases
Drug interaction check
Asha: Pulls from DailyMed and FDA label data, returns interactions with severity, citation, and clinician follow-up guidance.
ChatGPT: May summarize from training data without verifying against current labels. Pharmacology is a known weak spot for general LLMs.
Understanding a new diagnosis
Asha: Pulls from StatPearls and PubMed, returns evidence-graded explanation with patient-education-level language and clickable citations.
ChatGPT: Returns a fluent overview, often without primary-source citations unless SearchGPT is explicitly invoked.
Reading a lab report
Asha: Upload a PDF; Asha cites the relevant clinical reference ranges, explains the result in plain language, and flags values worth discussing with your clinician.
ChatGPT: Upload supported; the explanation is fluent but the reference ranges are not pinned to a verified clinical source.
Asking about a prescription dose
Asha: Refuses by design and points you to your prescribing clinician. This is the safety feature, not a limitation.
ChatGPT: Often answers with a generic-textbook dose plus a disclaimer. The disclaimer is not the same as a refusal.
Pricing breakdown
ChatGPT Plus has been $20/month since February 2023. ChatGPT Pro is $100 or $200/month depending on tier (per OpenAI's current pricing page). Asha Free covers 100 queries/month at no cost, and Asha Pro is $14.99/month, or $9.99/month billed annually ($119.88/year), for unlimited queries with a 30-day free trial (no card required to start). The pricing is intentional: medical guidance should not be a luxury good, and the medical-specific corpus does most of the heavy lifting on quality without burning compute on Sora video and Codex.
Frequently asked questions
Can I use ChatGPT for medical questions safely?
Yes for casual, low-stakes curiosity, as long as you verify with a clinician before acting. For anything where accuracy matters (medication, symptoms, diagnosis), a citation-grounded tool like Asha reduces the verification burden because the citations are already there.
Does ChatGPT cite sources for medical answers?
Sometimes. When SearchGPT is invoked, ChatGPT returns inline citations. In regular chat without web search, citations are often absent or summarized. Asha cites by architecture, every answer, every time.
How accurate is ChatGPT on medical questions?
Per a 2025 PMC analysis of GPT-5, the hallucination rate drops to 9.6% with web access and rises to 47% on fact-seeking tasks without internet. Asha sidesteps this volatility by retrieving from a curated medical corpus on every query.
Is Asha free?
Yes. The free tier includes 100 queries per month. Pro is $14.99/month, or $9.99/month billed annually ($119.88/year), with a 30-day free trial (no card required to start).
Can ChatGPT prescribe medications?
No AI is licensed to prescribe. ChatGPT will often discuss specific dosages with a disclaimer; Asha refuses prescription and dosing questions architecturally and points you to your prescriber. That refusal is the fiduciary design.
