Koboshi vs Anki

Anki is powerful. Koboshi is built for the words you meet.

Anki is the gold standard for spaced repetition, and we mean that. Many of us learned on it. Koboshi is built for a different moment: the word you just met, ready to review in seconds without the building.

Same word, two ways

One you build by hand. One builds itself.

Same word. Two ways to get there.

What Anki gets right

Anki set the standard

Battle-tested spaced repetition with FSRS built in, free on desktop and Android, and one of the richest deck ecosystems anywhere. If you love building and tuning your own system, nothing beats it, and the iOS app’s one-time 24.99 dollars is how a small team keeps it all free and open.

Where it asks a lot

It assumes you’ll build everything

Every card is yours to make, the setup takes patience, and several languages mean decks, tags, and workarounds. That is the price of its flexibility, not a flaw, but it is real work.

What Koboshi changes

Keep the serious review. Lose the busywork.

AI builds the card

Meaning, example, level, synonyms, audio, and the word across your other languages. Seconds, not minutes.

Multilingual from the ground up

One idea across your languages, each on its own schedule.

Capture from anywhere

Screenshots, articles, chats, and your old CSV lists, including Anki exports.

Modern review, zero setup

FSRS-based scheduling out of the box. No deck files, no tuning required to start.

The honest trade-off: Anki has the higher ceiling if you love to tinker. Koboshi asks far less of you to get going. Different tools, different moments.

Side by side

Questions

Fair questions, fair answers.

Is this an Anki replacement?

For many language learners, yes. Power users may happily run both.

Can I import my Anki deck?

Yes, by CSV, with optional AI enrichment.

Does it use FSRS like Anki?

Yes. No setup needed.

Where next

Your newest words might not be in Anki at all.

They might be sitting in ChatGPT, scrolling further out of reach every day.
