Unlock with ProThe problem, in the searcher’s words
I don't want to post on Reddit or TikTok about my symptoms, but I also don't want to call my doctor or ask a friend right away. I just want to talk something through first, maybe with a 'persona' that feels like a doctor, a mom, or a caretaker, before I decide what to actually do.
There's a gap between 'silently worrying' and 'posting it publicly for strangers to see.' People already use ChatGPT for this kind of thing, but it's generic — there's no sense of a tailored persona or grounding in what real people with the same issue have actually said.
The idea here is a private space to vent/ask about physical health, mental health, or insurance confusion, matched with real social data, without exposing yourself online or to someone you know.
What the thread shows
Only the OP argues for the idea; the three commenters either question its differentiation from existing AI chat, raise a medical-liability concern, or dismiss it outright, with no one expressing willingness to pay.
“a patient could describe a persona of a person they want to have a conversation with (doctor, friend, caretaker) and real time social data (API integration) matches the patient with the advice they need to seek personalized care WITHOUT posting online or asking someone in real life first.”
“How would this be different than asking ChatGPT ?”
“This would essentially be baking in several system prompts into an existing AI system. It should be relatively easy to implement. Go ahead and try it — see how it feels.”
“Sounds like a waste of time to me. But having this lead up to an actual doctor chat may be interesting.”
Target customer
Who
People with health anxiety or embarrassment who want to discuss physical/mental health symptoms or insurance confusion privately
Context
They're stressed about a symptom or insurance issue but don't want to post publicly on Reddit/TikTok, call their doctor immediately, or ask a friend or family member first
What to build
- Custom persona creation (relationship type, tone, characteristics)
- Private, non-shared chat interface with an LLM
- Basic symptom/insurance-question intake flow
- Disclaimer and escalation prompts pointing to real medical/insurance resources
- Conversation history saved locally/privately
Build note — Would require HIPAA-aware data handling given health content, an LLM backend (e.g., OpenAI API) for persona-based dialogue, and social listening APIs (Reddit/TikTok) for the 'real posts from real people' matching described in the post. A commenter flagged unlicensed-medical-advice liability risk (e.g., reassuring someone who actually has a serious condition) as a core legal/product risk to design around.
Later, if it lands
Who’s already out there
General-purpose AI chat that can be prompted to role-play as a doctor, friend, or other persona and answer health or insurance questions privately.
Gap: No built-in persona presets tailored to health contexts, no integration of real social-listening data from health forums, and no structured escalation path to real care.
AI-driven symptom checker app that asks users questions and suggests possible conditions or care pathways.
Gap: Focused on symptom triage, not on persona-based conversational support or insurance questions, and not mentioned in this thread so its fit is unverified.
Demand read
No commenter expressed willingness to pay, and the thread shows more skepticism ('waste of time,' 'how is this different than ChatGPT') than validated demand, so any market signal here is weak and unconfirmed.
Worth digging into before you build
6 to considerNo idea is a sure thing at this stage — these are open questions worth checking yourself, not a verdict against building it.
Single Voice
Only the OP (who is also pitching the idea) argues for its value; all three commenters are neutral-to-skeptical.
Weak Demand
No willingness-to-pay signals; commenter Creepiepie explicitly calls it 'a waste of time.'
Already Solved
cowtamer1 argues the core feature is just system prompts on an existing AI system like ChatGPT, i.e., largely achievable today without a new app.
Sensitive Domain
Health/mental health/insurance advice domain; darthwalsh raises a real practicing-medicine-without-a-license/liability concern that needs editorial and legal review before publishing.
Thin Source
