Systems

A System is Nomain's model of one of your software systems, built from its code, jobs, copybooks and documents. It is the thing you explore and chat with.

Learn about Systems

Repositories and sources

Build a System from one or several source repositories, with per-repository rules for what to include. Programs and data link up across them.

Connect your sources

Domains and business processes

See which part of the business each System covers, and read end-to-end business processes as clean, navigable diagrams.

Explore processes

Chat with your system

Ask questions in plain language. The agent searches your code and documents, cites its evidence, and remembers what matters to you.

Start a conversation
