AI-native document production
You know the answer.
We help you prove it.
Turn expert knowledge into submission-ready documents with grounded citations, structured review, and a complete audit trail.
Reactor coolant pressure boundary is verified against submitted source tables.
Material properties trace to the current revision of the design basis report.
Reviewer comments resolved with retained section decisions.
Trusted use cases across high-stakes submissions
Submission teams need confidence, not more drafting tools.
NexusDoc360 is designed around the evidence trail: source material, review decisions, cited output, and final export.
"We cut our RFP response time from three weeks to four days, and for the first time we could actually show the procurement team where every claim came from. The audit trail alone justified the switch."
"The source-monitoring feature is the difference between catching an outdated citation in draft review and catching it the night before a NRC submission. It has already paid for itself twice over."
Your document risk is growing. Your workflow should not.
Regulated document production fails when evidence, review, and export are treated as separate tools.
Missing citations
Claims move faster than sources. Nexus keeps every generated statement tied to the evidence behind it.
Stale source files
Teams review against old revisions. Nexus watches source updates and keeps document sections aligned.
Review drift
Feedback gets buried in email threads. Nexus routes section-level decisions through one workspace.
Audit gaps
Auditors ask how an answer was produced. Nexus preserves the source, reviewer, and export trail.
Template chaos
Every submission has a different shape. Nexus maps your required structure before drafting begins.
Export defects
Final formatting should not break the story. Nexus locks decisions before Word or Markdown export.
A 3-phase system for evidence-backed documents
Connect source material, draft with grounding, then review and export with an audit trail.
Connect your data
Upload source documents, reports and reference files. NexusDoc360 reads and indexes everything.
Define the structure
Import a template or paste any table of contents. The structure is mapped and ready instantly.
AI generates content
Every section drafted from your data. Every claim grounded. Every source cited. Automatically.
Purpose-built layers for the Nexus document stack
Each product owns a different part of the journey, from source grounding to simulation-backed evidence.
Flagship product

Knowledge engine
Nexus Context
Nexus Context is the retrieval and grounding layer that sits between your source documents and any LLM. It indexes your enterprise knowledge base, surfaces the right passages for any query, and returns every answer with a citation back to the source. Use it to power NexusDoc360, your own internal tools, or customer-facing applications — with the same source-grounding guarantees.
- Index any mix of PDFs, Word, HTML, spreadsheets, and databases
- Hybrid keyword + semantic retrieval with reranking
- Every answer returns source citations with offsets

Nexus Atoma
Nexus Atoma is the physics layer for NexusDoc360. Where Nexus Context grounds your prose in source documents, Atoma grounds your numerical claims in real simulations. Build a digital twin of the asset under review — a reactor, a turbine, a bridge — run the regimes the regulator cares about, and drop the resulting curves, spectra, and margins straight into your submission. Every number in the document traces back to a solver run.
- Live digital twin — geometry, materials, boundary conditions
- Multi-physics solver: thermal, structural, fluid, neutronic
- Scenario library mapped to regulatory transients (DBA, SSE, OBE)
