# Platform overview

> How Campus fits together — learners, trainers, Henrik, and the AI layer.

Campus brings four things into one Next.js application:

<CardGroup cols={2}>
  <Card title="Courses & cohorts" icon="book-open">
    Structured, phase-gated course material plus cohort-based live training.
  </Card>

  <Card title="Henrik" icon="robot">
    An AI coach embedded throughout the platform.
  </Card>

  <Card title="Assessments & credentials" icon="graduation-cap">
    Automatically scored exams that issue certificates and awards.
  </Card>

  <Card title="Lifecycle emails" icon="envelope">
    Timed nudges that keep learners moving between live sessions.
  </Card>
</CardGroup>

## Two audiences

* **Learners** take courses, talk to Henrik, and earn credentials.
* **Trainers & superadmins** run cohorts, schedule live sessions, and review progress.

The same person can be a learner in one cohort and a trainer in another — see [Permissions & roles](/docs/en/security/permissions).

## Two layers of AI

1. **Henrik** — the conversational coach you chat with.
2. **The AI layer** — invisible intelligence: personalization, email generation, recaps, and assessment scoring.

Both share one context assembly and both respect **phase gating as a hard security boundary** — locked content never reaches the AI. See [Security overview](/docs/en/security/overview).

There is also an invite-only beta: [Agents](/docs/en/features/agents), where users build personal AI agents with their own routines and tools.

## Languages

Campus ships in **English** and **German** throughout. German uses the informal **du**. Learners can also choose a language [per course](/docs/en/learners/courses).
