# Concepts

Everything in Trevize is built from a small set of concepts. Understanding how
they relate makes the rest of the product predictable.

- [**Workspaces & projects**](/concepts/workspaces) — the team boundary that owns
  your connected repositories, members, and billing.
- [**Sessions**](/concepts/sessions) — live, collaborative working sessions where
  you and an agent build together in real time.
- [**Automations**](/concepts/automations) — autonomous loops that keep working on
  a goal between sessions and open pull requests as they make progress.
- [**Tasks & implementations**](/concepts/tasks) — the unit of work: a brief
  becomes an implementation, which becomes a pull request.
- [**Briefs**](/concepts/briefs) — the specification that tells an agent what to
  build.
- [**Knowledge & memory**](/concepts/knowledge) — the durable context agents carry
  across sessions so they don't relearn your codebase every time.
- [**Insights**](/concepts/insights) — the signals Trevize surfaces about what's
  happening across your work.

If you're just getting oriented, start with [Get started](/get-started) for the
big picture before diving into individual concepts.
