questions

What counts toward the daily limits, and when do they reset?

Each different word you look up counts once a day toward definitions, so looking it up again the same day is free. Each message you send counts toward 선생님. Both start over at midnight UTC. Video imports count per calendar month, and importing the same video again that month is free.

Is my payment safe?

Yes. Checkout is run by our payment provider. Your card details go straight to it and never reach our servers; we only learn which plan you have.

How do I cancel?

In the billing portal. Every billing email links to it, and so does your profile page.

What happens when a subscription ends?

Premium stays until the end of the period you paid for. After that your account goes back to the free plan, and your texts, vocab lists, stats and streaks stay as they are.

Import a YouTube video

Any Korean YouTube video with captions can become typing practice. A bookmark grabs the captions right from YouTube in your browser, and korean-assist plays the video along as you type.

  1. 1Add the bookmark (once)

    Drag this button to your bookmarks bar: → korean-assist

    • No bookmarks bar? Press ⌘+shift+b (Chrome, Edge, Safari), or in Firefox right-click the toolbar → “Bookmarks Toolbar”.
    • Firefox and Safari: you can also right-click the button → “Bookmark Link…” / “Add Link to Bookmarks”.
    • Any browser: then add a new bookmark named “→ korean-assist” and paste the code as its address.
  2. 2Open a Korean video on YouTube

    Any video with Korean captions works: human-made subtitles or YouTube’s auto-generated ones. Look for the CC button on the player.

  3. 3Click the bookmark

    A small note appears on YouTube while it grabs the captions, then “sent to korean-assist ✓”. Your video keeps playing (or stays paused) just as it was.

  4. korean-assist with the imported transcript in the editor and the linked video shown above it

    4The transcript lands in korean-assist

    A new tab opens with the captions in the editor and the video linked. Trim or edit the text if you like, then save it to your library or start right away.

  5. Typing along with the video playing above the words

    5Type along with the video

    As you finish each word (or sentence, see settings), the video plays that part so you hear the real speaker. ctrl+s replays what you just typed, ctrl+p plays what’s next, and ctrl+m switches to the synthetic voice.

Works in desktop Chrome, Edge, Firefox and Safari. If you ever get a message that your bookmark is out of date, drag the new one from step 1 to replace it.
