## What is CoreTube?

You sat down to study with a video, and somehow you're watching something else. Sound familiar?

CoreTube is a video viewer built for learning. It lists public videos that match only the channels and keywords you register. There is no trending page and no recommended feed, so what you see when you open the app is what you chose to learn.

CHOOSE WHAT YOU WANT TO LEARN
- A quick first-run setup: tap a suggested keyword to register it
- Add channels by searching for a name, @handle or URL
- Register up to 10 channels and keywords in total, and drag to put them in your order

FIND IT, PICK IT, KEEP GOING
- The Channels tab shows the latest uploads from your channels; the Keywords tab shows videos matching your keywords
- Sort by newest, oldest, highest rated, most viewed and more
- Scroll down to load more, pull down to refresh
- Got a sudden question? Search from the Home screen. Searches only run when you submit them

KEEP THE GOOD ONES
- Save videos into folders under Favorites
- Sign in with Google or Apple (iPhone) and your sources and favorites sync across your devices

JAPANESE AND ENGLISH
Switch the display language any time in Settings.

GOOD TO KNOW
- Videos play in YouTube's official embedded player, unmodified. YouTube may show ads and related videos inside the player
- We can't guarantee that unrelated videos or Shorts never appear in a list
- Videos cannot be downloaded
- Not intended for children under 13
