# FAQ

> Frequently asked questions about Cardboard.

## General

<AccordionGroup>
  <Accordion title="What is Cardboard?">
    Cardboard is a browser-based AI-powered video editor. You can upload video footage, edit it using plain-English AI commands or manual timeline editing, and export professional-quality videos — all from your browser.
  </Accordion>

  <Accordion title="Do I need to download anything?">
    No. Cardboard runs entirely in your browser. There is nothing to install. You just need a modern browser like Chrome, Firefox, Safari, or Edge.
  </Accordion>

  <Accordion title="Does Cardboard work on mobile?">
    Cardboard is optimized for desktop and laptop browsers. You can access it on tablets, but the full editing experience works best on a screen that is at least 13 inches wide.
  </Accordion>

  <Accordion title="Is my content secure?">
    Yes. Your media files are encrypted in transit and at rest. Cardboard does not use your content to train AI models. Only you and people you share a project with can access your files.
  </Accordion>

  <Accordion title="What browsers are supported?">
    Cardboard works best on the latest versions of Chrome and Edge. Safari and Firefox are also supported. We recommend Chrome for the best performance.
  </Accordion>

## AI editing

<AccordionGroup>
  <Accordion title="How does AI editing work?">
    You type a plain-English instruction in the **AI Chat** panel (for example, "trim to the best 30 seconds" or "add captions"). The AI analyzes your video, decides what to do, and applies the edits to your timeline. You can see exactly what changed and undo anything. Learn more in [How to Talk to Cardboard](/learn/talk).
  </Accordion>

  <Accordion title="What can the AI do?">
    The AI can trim, split, and rearrange clips. It can create montages, add transitions, generate captions, adjust pacing, add music, apply effects, find specific moments in your footage, and much more. See [How to Talk to Cardboard](/learn/talk) for examples.
  </Accordion>

  <Accordion title="Can I undo AI edits?">
    Yes. Every AI edit can be undone with **Cmd/Ctrl + Z** or by typing "Undo that" in the AI Chat. Your original media files are never modified.
  </Accordion>

  <Accordion title="Does the AI work in languages other than English?">
    The AI Chat currently accepts instructions in English. However, the AI can transcribe and caption videos in 20+ languages. See [Auto-Generated Captions](/learn/captions) for the full list.
  </Accordion>

  <Accordion title="How accurate are AI-generated captions?">
    Captions are highly accurate for clear audio in supported languages. You can always review and edit captions after they are generated. Background noise or overlapping speakers may reduce accuracy.
  </Accordion>
</AccordionGroup>

  </Accordion>

  <Accordion title="How many projects can I have?">

<AccordionGroup>

  </Accordion>

  <Accordion title="Can I export to Premiere Pro or DaVinci Resolve?">
    Yes. Cardboard can export an XML timeline that you can import into Adobe Premiere Pro or DaVinci Resolve for further editing. See [Export Your Video](/export/export-your-video) for details.
  </Accordion>

  <Accordion title="How long does exporting take?">
    Export time depends on the video length, resolution, and complexity. A typical 2-minute 1080p video takes 30 seconds to a few minutes.
  </Accordion>
