Ask
Evidence, not obedience
The health questions your doctor won't answer.
Ask about vaccines, drugs, or any intervention. We search real science, show you what we found, and leave the decision to you. No gaslighting. No "trust the experts." Just sources you can check yourself.

Not medical advice. A research starting point. We show uncertainty, conflicts, and the sources behind each claim.

Why OpenNeedle
Other health AI is built for doctors. This is built for you.
Most health AI is built for the doctors and the institutions that profit from the schedule. OpenNeedle is built for the person being asked to take the needle. The burden of proof sits on the intervention, not on you.
We search the actual literature through BGPT, name who funded each study, and report what the evidence supports, not what a press release claims. Nothing here is settled like a math proof. Every claim was tested, and you can see how, and where it falls short.
How it works
From question to evidence in four steps.
Every answer is built to be inspected, not just believed.
Search
We search the scientific record through BGPT and show you the exact search terms.
Weigh
We read the evidence and write a plain-English answer with inline citations.
Inspect
Every claim links to its source. Open it, read it, decide for yourself.
Evidence over consensus
Protect the person, then follow the evidence.
Consensus is not proof, and an average is not your risk. Real answers come from studies that were actually run — and the weight of each finding depends on how well it was tested. When a system demands you comply, it should be the one that has to justify itself.
Read the method →If the claim matters to your health, it should be backed by real studies — not by consensus, not by a press release.
