# Get Started: Key Concepts
URL: /docs/get-started/key-concepts

The words we use, defined.

A few terms come up throughout Nudgly. Knowing them makes everything else clearer.

<Terms>
  <Term name="Assistant / personality">
    The character you talk to. You pick one; you can switch anytime. Same abilities, different style.
  </Term>
  <Term name="Task">
    Something to be done. You can complete it yourself or hand it to the assistant.
  </Term>
  <Term name="Nudge">
    Something the assistant noticed and is offering to handle, shown on your Overview with a one-tap action.
  </Term>
  <Term name="Workflow">
    An automation the assistant runs for you when a trigger happens — a time arrives, or an event occurs. The assistant does the steps. Example: every morning, pull your calendar and send you a brief.
  </Term>
  <Term name="Routine">
    A ready-made checklist you start from, like a morning routine of wake, news, workout, breakfast. You edit the steps and add them to your tasks for today or tomorrow. You do the steps; they do not repeat on their own.
  </Term>
  <Term name="Trigger">
    The thing that starts a workflow. Either a time (every Monday at 9am) or an event (a meeting ends, a task is completed).
  </Term>
  <Term name="Approval">
    Before the assistant sends an email, pays, books, or deletes something, it shows you an approval card and waits for your OK. This happens in every mode, even Full access.
  </Term>
  <Term name="Integration">
    An app you connect (Gmail, Outlook, Google Calendar, Slack, Notion) so the assistant can work in it.
  </Term>
  <Term name="Action">
    A single thing the assistant does, like reading your calendar or drafting an email.
  </Term>
  <Term name="Credits">
    What actions are paid with. Bigger jobs use more credits than small ones. Your plan includes credits each month, and the free trial gives you a daily amount.
  </Term>
  <Term name="The assistant’s computer">
    A browser your assistant runs for you, for websites that have no app to connect. It can fill in forms, book, and pay there, and it asks you first before it books or pays.
  </Term>
</Terms>

The difference between a workflow and a routine matters: if the assistant does the work, it is a workflow. If you do the work, it is a routine.
