  </Accordion>

  <Accordion title="Can I edit captions after they're generated?">
    Yes. The [caption editor](/workflows/caption-editor) lets you edit any caption track at any time. Edits are saved as a new version without overwriting the original. You can switch between versions anytime.

  </Accordion>

  <Accordion title="Can I use Neolli without YouTube?">

  </Accordion>

  <Accordion title="Can multiple people work in the same workspace?">

  </Accordion>

  </Accordion>

  <Accordion title="Is there a cooldown for YouTube uploads?">
    Yes. YouTube API rate limits require a **15-minute cooldown** between uploads for the same video. If you see a cooldown message, wait and try again later.
  </Accordion>

    Yes. Failed jobs are **automatically refunded** — no need to contact support. See [A Job Failed](/troubleshooting/job-failed) for details on retrying.
  </Accordion>
