What NexDoc is
One question box. Three depths of answer.
Every answer is built from cited literature and graded A to D — so you know exactly how much weight it can carry at the bedside.
Deep Research
Minutes-long MeSH literature review
A full literature sweep over PubMed with verified MeSH terms, screened papers, and a printable evidence review. It keeps running on the server if you leave.
Discussion
Work a case through, turn by turn
Present a case and work it through with a running case memory. Fold in care models and evidence apps mid-discussion, then publish the case to your circle or export it as a PDF.
The answer stream
Answers you can defend, not just read.
This is the anatomy of a NexDoc answer: streamed text, structured clinical cards, an evidence grade with its source count, and PubMed references — in one column.
Structured clinical cards
Differential diagnosis, drug dosage, protocols, next best actions and lab interpretation — ranked, badged by urgency, exportable as images.
“Checked before answering”
Every answer shows the sources it consulted before it said a word — expandable, linked, with PMIDs.
Graded A–D
A single canonical evidence scale follows every source everywhere it is cited.

3 weeks of low back pain radiating below the knee, no red flags — image now or wait?
Weighing differentials and guidelines…
Without red flags, guidelines consistently recommend against routine imaging in the first 4–6 weeks — it does not change management and often surfaces incidental findings. Begin conservative management and reassess; image early only if progressive neurological deficit or red flags emerge.

Beyond search
Three instruments, one evidence base.
Deep Research writes the review. Care Models run the reasoning. Evidence Apps do the arithmetic. All of it graded, all of it cited.
Deep Research
A literature review that survives you closing the tab.
Deep Research clarifies your question, plans lines of enquiry, verifies MeSH terms against the thesaurus, and screens PubMed — then writes a printable evidence review with numbered sections and a full audit trail.
- Country-aware evidence
- Choose whose evidence to prioritise — searched first for local studies and practice, then widened globally.
- Every search shown
- “Show how this was searched” reveals the MeSH terms, queries run and hit counts behind every section.
- Runs on the server
- Interrupted reviews resume from their last checkpoint — nothing already searched is repeated.

Care Models
Clinical reasoning as a runnable pathway.
From a presentation: triage acuity, then rank the differential. From a condition: phenotype, ranked interventions, expected outcomes. Each model is versioned, evidence-graded and owned by a Clinical Circle.
- Adjust for my practice
- Fork any model privately — add inputs, prefer results, add outputs. The shared catalog stays untouched until the community agrees.
- Community-weighted ranking
- Results reason over the Evidence Graph, weighted by nodes the community has promoted.
- Save, export, share
- Keep a run history, export to PDF, or share a result image — each stamped with its evidence grade.

Evidence Apps
An App Store where every tool cites its sources.
Install evidence bundles — scores, criteria lookups, checklists, monographs — from a store organised by specialty. Logic apps compute; knowledge apps answer instantly.
- Chained workups
- Tools hand values to each other — PHQ-9 hands its suicide-risk item straight to the risk model, not the raw total.
- Graded bands
- Every score lands in a band with its own evidence badge, so the cutoff itself shows its provenance.
- Your feedback recalibrates them
- “This band felt wrong” — when enough doctors flag the same band, it opens for recalibration.

How it works
Find the evidence. Close the gap. Literally.
The tagline is the workflow. Answers flow out of the evidence base — and the questions it can’t answer yet flow back in as work for the community.
- 01
Ask, out loud or in writing
Type a clinical question, describe a case, attach a lab report or scan — or just talk it through with Live voice and turn it into a full evidence search when you are ready.
Quick · Deep Research · Discussion - 02
NexDoc finds and grades the evidence
It searches the literature, verifies MeSH terms, reasons over the Evidence Graph, and streams back an answer with structured cards — every source graded A to D and shown before it answers.
Checked before answering - 03
What can’t be answered becomes a gap
Searches nobody could answer, bands doctors keep overriding, practice diverging from the guideline — gaps register themselves on a public list of what medicine doesn’t know yet.
What we don’t know yet - 04
Circles close the gap
A Clinical Circle takes the question through a PICO thread. Every source is graded by 2+ reviewers, a panel records its verdict and dissent — and the shared care model changes version.
Panel verdict → model change
Clinical Circles
A circle forms around a condition.
It owns Care Models, hosts PICO threads, seats review panels, and merges graded evidence into model changes. This is where the answers come from — try the pieces below.
Panel answered
Concluded by a review panel of 3 · Grade A
Every source graded by 2+ reviewers; grades follow the source everywhere it’s cited. Verdicts record their dissent — and when they reopen.
Care model changed
v3 → v4 · merged into practice
The shared care model now says something different.
Evidence poll
At what PHQ-9 score do you escalate?
Answer to see what everyone else does — results stay hidden until you do.
Follow-up
What happened with the patient you assessed last week?
PHQ-9 Severity · the tool said “Moderate” · 9 days ago
One tap · your answer is what validates these tools.
What we don’t know yet
A public register of gaps in the evidence — most of them noticed automatically. Claim one and the community will know you’re on it.
- Nobody could answer this search
- Practice diverges from the guideline
- The panel could only grade this C or D
- Asked repeatedly, never answered
