Q — Can I take ibuprofen with my blood-pressure medication (lisinopril)?
Worth being careful with. NSAIDs like ibuprofen can blunt the blood-pressure-lowering effect of ACE inhibitors1, and taken regularly, the combination is associated with reduced kidney function2 — especially when a diuretic is also in the mix. Occasional use appears lower-risk in the published evidence3, but it's a question worth raising with your prescriber.

You already fact-check your chatbot.
People paste AI health answers back into a search box to see if they hold. ModernDoc does that work before the answer reaches you — sources attached, graded, and ready to open.
Keep the habit. It's one tap now.
Anatomy of a checked answer.
ModernDoc searches an indexed medical research corpus, screens every source against a retraction index, orders what survives by evidence hierarchy, and grades each source against 29 quality markers — then shows you all of it.
Intake
Your question, in plain language. When it needs more, ModernDoc asks a clarifying question before it answers.
Retrieval
The indexed medical research corpus is searched from multiple angles and the results are fused.
Screen
Every source is checked against a retraction index before it can appear in an answer.
Ground
The answer is checked against the evidence it retrieved — claims trace to sources.
Output
Sources arrive ordered strongest-first and graded — shown on the answer, not implied.
Systematic Review
A comprehensive review of the available research — it has already weighed the single studies.
systematic_reviewClinical Guideline
Official clinical practice recommendations — not one paper's opinion.
clinical_guidelineTop Journal
Published in a top-tier scientific journal — the venue itself is screened.
top_journalPeer Reviewed
Reviewed by medical experts before it was published.

Cited by hundreds of later papers — the field keeps building on it.

Counted, not claimed.
2,846,761 indexed research passages. 29 source-quality markers. 3 depths of research. Every number on this page is exact and verified — anything we can't verify isn't here.
Every number verified or absent — the ledger is the policy
Three depths. One standard of evidence.
A direct answer in seconds. A researched answer in about a minute. Deep research in a few minutes. Every depth cites graded sources you can open.
Direct
A plain-language answer to a straightforward question — cited, graded, ready to open.
Web-researched
Current, quality-screened sources brought into the answer when the question needs what's new.
Deep research
A full multi-source evidence review for the question you've been carrying around.
Strongest evidence first.
Proportion instead of panic: what the published research actually shows, ordered by evidence strength — and a plain line about when it's time to see someone.
And when the evidence says a clinician should take over, the answer says that plainly too.
Ordered by evidence hierarchy — each tier labeled on the answer
Weak evidence gets called weak.
Mixed findings are reported as mixed; thin literature is called thin. ModernDoc answers from the published research — not from what you want to hear.
Q — Does magnesium actually help with sleep?
The honest read: mixed. Some small trials report modest improvements in how quickly people fall asleep; reviews of that literature call it thin, short-term, and inconsistent. If you see it sold as settled science, that's ahead of the evidence — and your answer will say so.
Not a typical AI chatbot.
A typical AI chatbot is confident, agreeable, and uncited. ModernDoc is built to be checked: sources shown, quality graded, uncertainty stated.
AI can make mistakes. That is exactly why every ModernDoc answer shows its sources — so you can check.
Comparison reflects ModernDoc's shipped retrieval system.
Evidence-based information. Not a diagnosis.
Your questions are yours, and ModernDoc stays within its limits: cited context that prepares you for the visit — never a replacement for the clinician across from you.
If this is an emergency, call 911.

Questions, answered
Isn't this just another AI chatbot?
No — ModernDoc retrieves from indexed medical literature and current quality-screened sources, grades every citation, screens out retracted studies, and checks each answer against its own evidence. It asks clarifying questions before answering, and it says so when the evidence is thin.
Is this medical advice?
No. ModernDoc provides evidence-based health information with cited sources. It doesn't diagnose or treat, and it isn't a substitute for a clinician. If you may be experiencing an emergency, call 911.
What sources does ModernDoc use?
Peer-reviewed medical journals, systematic-review libraries, and public health authorities — each answer shows its exact sources, graded by evidence quality. Read how answers are made on our sources page.
