Extraction, typed.
Nine entity types — person, organisation, project, concept, technology, location, event, document, preference — plus the relationships between them. Not a flat embedding soup.
Your second brain, as a graph.
Drop in your notes, PDFs, meeting transcripts or note-app folders. Nexus figures out who is in them, what projects are underway, what ideas have been discussed, and how everything is connected. Ask it anything — "what has Priya been working on?" — and get a grounded answer with links to the exact notes it came from.
Already running across 600+ teams on the Mariete platform.

What it does
Built around one idea: finish the work.
Configure once, run continuously. Every capability below is a production-grade surface, not a demo.
01
Extraction, typed.
Nine entity types — person, organisation, project, concept, technology, location, event, document, preference — plus the relationships between them. Not a flat embedding soup.
02
Bi-temporal by default.
Facts carry both valid time (when they were true in the world) and system time (when Nexus learned them). The graph shows how your understanding evolved.
03
Grounded answers.
Queries return answers that cite specific entities and source documents — not generic chunks. If Nexus can't support a claim with evidence, it says so.
04
Entity pages.
Click a person, see every meeting, project and preference. Click a concept, see how it evolved. Click a document, see every entity it mentions.
In the wild
Five ways teams actually ship with Nexus.
Scenario · 01
Pull 18 months of reading into one view.
A researcher drops in 18 months of papers, notes and highlights. Nexus surfaces the handful of ideas that quietly connect lines of work the researcher had thought were separate.

Intelligence suite
Four surfaces. One runtime. Zero duct tape.
Every Nexus module shares the same orchestration layer, the same audit trail, and the same integration fabric — so a win in one surface lands everywhere.

Under the hood
The surfaces the product is made of.
The canvas
Typed entities, typed edges.
A React Flow canvas with colour-coded entity nodes: person, organisation, concept, project, document. Cluster by project, by team, by theme.
- Typed nodes with per-type colour
- Cluster by project / team / theme
- Open any node as its own page

Timeline
See how the graph changed.
Scrub the timeline: watch entities appear, relationships strengthen, preferences shift. Bi-temporal storage means history is a first-class citizen.
- Valid-time scrubber
- System-time diffing
- Entity history pages
