KoboshiBeside Duolingo
Keep Duolingo. Add memory.
Duolingo is a great companion for building your base. The streak keeps you showing up, and it even reviews words as you go. It just works with its own words, by design. Koboshi holds the rest: the words you meet on YouTube, in ChatGPT, in books, reviewed before you forget.
Every app remembers its own words. Koboshi remembers yours.
The moment Koboshi is built for
You hear a new word in a Duolingo story. You can't save it there, and you're good at forgetting.
Before
Screenshot it, or paste it into ChatGPT. Good explanation. The chat scrolls on. Next week the word is gone.
With Koboshi
Save it in seconds. AI explains it once, properly, with examples and the same idea in your other languages. Koboshi brings it back right before you would forget. The word stays.
The whole system, two lines
It really is this small.
Questions
The honest answers.
Should I quit Duolingo for this?
No. Different jobs. Duolingo builds the habit and the base. Koboshi keeps the words you meet, from everywhere.
Does Koboshi import from Duolingo?
There is no official Duolingo export. Saving a word as you meet it takes seconds. Words kept in ChatGPT or notes can be imported.
I finished the course. Now what?
Vocabulary becomes the main wall. See the B1–B2 vocabulary page.
Where next
Been pasting words into ChatGPT for months?
They are not lost. There is a clean way to get them all out.
