About this app

Is your “Watch Later” and saved posts list growing?

You save videos—but don’t watch them.
You watch them—but don’t remember.

English phrases from Shorts.
Useful tips from Reels.
Knowledge you found on YouTube.

You think, “This is good.”
A few days later, it’s gone.

Why does this keep happening?

Even when we try hard to memorize,
we forget about 46% of new information within one day,
and nearly 70% within a week.

This isn’t a guess.
It’s proven by the Ebbinghaus Forgetting Curve.

Let flashcards handle remembering for you

This app is built on scientific spaced repetition.
It reminds you to review right before you forget—
so short-term memory becomes long-term memory.

Just 3 minutes at a time is enough.

How does it work?
1. We notify you right before memory fades

“15 cards you’ll forget tomorrow if you skip today.”

The app calculates the optimal review timing.
Cards you know well appear less often.
Cards you struggle with appear more—automatically.

2. Create flashcards in 3 seconds

Watching Shorts and find a great phrase?
Save it instantly as a card.

Hint on the front.
Answer on the back.
Add notes if you want.

3. Just paste a YouTube link

Paste a YouTube link and AI analyzes the subtitles,
then automatically turns key points into flashcards.

For language videos,
expressions and example sentences are neatly organized.

4. 3 minutes on your commute is enough

Swipe once to mark “Remembered / Not Remembered.”

On the subway.
During lunch.
Before sleep.

Those small moments add up.

5. Missed cards come back again

Cards you get wrong appear again at the end of the session.
Until you get them right.

No more “kind of remembered” moments.

6. Build your own decks with tags

English words, Japanese phrases, Chinese conversation,
coding terms, hobbies—anything.

Tag them to review only what you need.
Colors and icons help you organize visually.

7. See your learning in numbers

Reviewed cards.
Accuracy rate.
Study streaks.

Clear stats keep you motivated.

8. Check instantly from your Home Screen

See pending review cards at a glance with widgets.
One tap to start reviewing.

9. Even faster with Siri (iOS)

“Hey Siri, start flashcard review.”

Long-press the app icon to add cards instantly.
