What is Nex

Nex is a context layer for AI agents. It unifies customer-facing signal from the tools where work actually happens — WhatsApp, email, Slack, meeting transcripts, support tickets, product events — into a single knowledge graph per workspace. AI agents use that graph as ground truth to answer natural-language queries, follow playbooks, and automate workflows. The REST API lets you ingest context, query it, and wire your own agents into the same substrate Nex itself runs on.

Ask your context anything

Natural-language queries across every connected source

Turn workflows into playbooks

Guided agent workflows with context-driven decisions

One context across all

A unified integration layer for every tool in your stack

Building blocks

The API exposes the primitives that make up the context graph: the schema of your entities, the records that populate it, the relationships between them, the context you ingest, and the intelligence layer that compounds it over time.

Schema

Define object types and attributes for your knowledge graph

Records

Create, read, update, and delete entities in the graph

Relationships

Model how entities in the graph connect to each other

Context

Ingest unstructured context and query it in natural language

Insights

Stream AI-derived insights back into your own systems

Graph

Traverse the full knowledge graph for an entity

Lists

Group records into working sets for agents and workflows

Tasks & notes

Attach actions and free-form context to any record

Timeline & search

Audit history and full-text search across the graph
