  • 27 October 2017Soon: Update to the Spaced Repetition Scheduling

    (Update: As I wrote in this post there will be custom settings for the SRS so it's possible to keep the scheduling more or less as it is now).

    The default review intervals for kanji flashcards will be revised In the next update, which should help ease the review load for long time users.

    • There will be 10 piles instead of 7 (not counting the first box which holds restudy and new cards).
    • The multiplier used is approx 2.05, leading to : 3 7 13 26 53 109 223 457 936 1919 For the first 7 reviews the intervals are a little bit lower than the current values, but otherwise pretty close.
    • The maximum base interval increases from approx. 8 months to 5 years (~240 days to ~1900 days).
    • Keep in mind you can still use "Easy", which further multiplies the interval by 1.5x

    I was talking to someone about that. Someone else just brought it up on the forum so I thought I'd confirm this upcoming change and invite you to make suggestions if you like in this thread.

    What will happen to my SRS cards?

    After the update, answering "Yes" or "Easy" to the cards in the last box will now give them a greater interval. So over time the review load will decrease. and further separate well known cards from newer ones. Existing flashcards are otherwise unaffected. The SRS chart should in theory display just the same, the cards with 7+ reviews will all appear in the last box of the graph.

  • 13 October 2017F.A.Q.: How do I reset my flashcards?

    I added a new section to the Frequently Asked Questions : "How do I reset my flashcards?"

    This is a fairly common question for users who return to the site after taking a medium / long break. If you are going to go through the RTK book again, or some other kanji method and want to add kanji cards back in order this could make sense.

    If you just took a long break from reviewing however it's recommended to let the SRS take care of it. Decide how many cards you are going to review per day, say, 30... or how much time (say, 30 mins). Once you have reviewed that amount, end the review with the End button. Trust your memory, even if you stop all your Japanese study for half a year, you may still remember 10 to 20% of the kanji. Those kanji are better off to remain scheduled with a long interval, and you will end up with less reviews over time.

    If you prefer to start over, then I recommend to use and abuse the Easy answer. to reduce your review load over time. Keep in mind you can always answer Hard later if you were overconfident, and this will move the kanji card back one box, and to a smaller review interval, so not much harm done.

  • 10 October 2017Today's minor updates

    The following relatively minor changes went live today:

    • Increased the limit for the dictionary lookup results. In most cases it wasn't an issue for for a few of the most common kanji there can be a lot of common words and this caused some of them to simply not appear in the list
    • The documentation now includes a section about the Dictionary
    • The "Flashcards" menu in the main navigation has been reordered to "Manage Flashcards" > "Flashcard List"
    • The forms on Register, Edit Account and Change Password pages have been improved to provide better feedback for validation errors.Hopefully this makes signup a little smoother, especially for non-english users
  • 2 October 2017NEW : Highlight entries with known kanji in Dictionary

    Today's update adds an interesting feature for users of Koohii flashcards. The dictionary lookup in Study and Flashcard Review pages now highlights vocabulary entries made of known kanji.

    Currently a "known kanji" is simply a kanji for which you have added a flashcard. In the future this may be refined based on your feedback. Should a "known kanji" also be reviewed once? Should it include kanji in the failed card pile? Etc.

    In this example, a verb made of a single kanji (plus kana suffix) will be highlighted and thus brought to the user's attention. This can provide a good example word to remember the kanji.


    In this second example the user has learned the first 50 kanji with the RTK method (index #1 to #50). The second word is not highlighted yet but once the user has learned 大 (kanji #112 "large") then the second word will be highlighted too.


    Over the weeks and months as you add more flashcards and your "known kanji" expands, and you revisit the dictionary during flashcard reviews, new entries will be highlighted.

    A key point with this approach is that any vocabulary item that is highlighted is always based on previous knowledge.

    Do you find this feature useful? How does it fit into your study and how would you like to see it improved? Let me know via contact page or this forum thread.

    This feature corresponds to Github issue #125.
