# FAQ

> Answers to the most common questions.

<AccordionGroup>
  <Accordion title="Do I need to install anything to use xkat?">
    No. xkat is a [zero-setup](/en/learn/workspace/zero-setup) environment — open a
    lesson and the browser becomes a full dev and execution environment. A
    [desktop app](/en/platform/desktop-app) is also available.
  </Accordion>

  <Accordion title="Is xkat just videos?">
    No — lessons open a [Dynamic Workspace](/en/learn/workspace/overview) where you
    write and run real code with an editor, terminal or live preview, and an
    [AI Tutor](/en/learn/ai-tutor).
  </Accordion>

  <Accordion title="What's the difference between membership and AI Credits?">
    [Membership](/en/platform/membership-tiers) controls which courses you can
    take. [AI Credits](/en/platform/ai-credits) control AI usage like course
    creation and AI import. They're independent.
  </Accordion>

  <Accordion title="What languages is xkat available in?">
    Nine: English, Korean, Japanese, Chinese, German, Spanish, French, Hindi, and
    Indonesian. See [Supported Languages](/en/get-started/languages).
  </Accordion>

  <Accordion title="Can anyone create a course?">
    Yes — [Studio](/en/studio/overview) is free to design courses and knowledge
    graphs. AI features use [credits](/en/platform/ai-credits), and selling courses
    with revenue payouts requires the [Creator](/en/platform/membership-tiers) tier.
  </Accordion>

  <Accordion title="How much do creators earn?">
    Creator-tier creators receive **90%** of their course revenue. See
    [Monetization](/en/studio/monetization).
  </Accordion>

  <Accordion title="Can I keep the code I write?">
    Yes — connect GitHub and use [GitHub Sync](/en/learn/workspace/github-sync) to
    keep your work in a personal repository.
