# FAQ & troubleshooting

> Quick answers to the most common issues

<AccordionGroup>
  <Accordion title="The bot isn't answering — what do I check?">
    In order of likelihood:

    1. **Is the bot enabled?** Check the master switch in [Bot settings](/bot/settings).
    2. **Is the channel selected?** The bot only answers in channels you've picked in Bot settings.
    3. **Do you have credits?** At zero balance the bot pauses — see the [Billing](/billing/credits) page.
    4. **Is your knowledge Ready?** Sources still in Pending/Processing/Error aren't used in answers.
    5. **Does your knowledge actually cover the question?** If not, the bot deliberately stays silent instead of guessing — see [How the bot answers](/bot/how-answers-work).
  </Accordion>

  <Accordion title="A knowledge source is stuck in Error. What now?">
    Open the source — the error message says what went wrong. Common causes: an unreachable or login-protected URL, or an unsupported file format. Fix the cause and re-add or reindex the source. Failed ingestion doesn't leave broken knowledge behind.
  </Accordion>

  <Accordion title="What file types can I upload?">
    Only `.md` (Markdown) and `.txt`. Export other formats to plain text first. See [Uploading files](/knowledge/files).
  </Accordion>

  <Accordion title="Can the bot make things up?">
    No. It answers strictly from your knowledge base and links its sources in every reply. If it has nothing relevant, it stays silent and routes the question to your trusted members via [auto-learning](/knowledge/auto-learning).
  </Accordion>

  <Accordion title="Do members need to mention the bot to get an answer?">
    No — the bot detects questions in monitored channels automatically. Members just ask naturally.
  </Accordion>

  <Accordion title="How do I get more credits?">
    Credits refill each billing cycle from your plan's allowance. To get more: claim the one-time [Pro trial](/billing/promo-codes), redeem a promo code, or move to a higher plan.
  </Accordion>

  <Accordion title="Can I connect several Discord servers?">
    Yes. Each server becomes its own workspace with an isolated knowledge base, team, plan, and credit balance. Switch between them in the dashboard sidebar.
  </Accordion>

  <Accordion title="Who can teach the bot new answers?">
    Only members you've marked as trusted (by role or individually) in [Bot settings](/bot/settings). Answers from anyone else are never learned.
  </Accordion>

  <Accordion title="I removed a knowledge source — will the bot still use it?">
    No. Deleted sources drop out of answers immediately.
