Also, in search for SRS that works, and so I have deviated from the ways of Anki. I think it can be made to include Japanese, but it’s unlikely for me to go that far.
My old project is not online anymore. [source code]
Features and principles
- Reading only
- Multiple answer input (
;separated), with options to require multiple important readings - No real synonyms. Warning shake at best. All answers must exist in the dictionary.
- Typing and auto mark as right/wrong. No changing from wrong-to-right or vice versa.
- Undo (via keyboard shortcut) is sent to the end of review, rather than immediate retyping. Middle button “not sure” is there for half-wrong (Esc shortcut).
- Wrap up every 20 items, but can be done earlier. (F1, and I sometimes wrap-up at 10 items. No need for otherwise decision paralysis.)
- Restudy (drill) wrong items after wrap up.
- Search for inclusive vocabularies, and put studied items first. (Personal preference for hiding reading only if due in 1 hour. Tomorrow or later reviews don’t worth hiding reading.)
- Hanzi break-down and build-up. Also put studied items first.
- Vocab and Hanzi searching can include reading alongside to narrow the search
- No separating vocab and Hanzi. (Not really an issue for Chinese, but could apply to Japanese.)
- External links and Notes with rich text and images. I encourage taking notes, even if only readings are quizzed.
- Levels, of course. Sorted by language proficiency test levels (HSK), then by most common Hanzi.
- You can start from a mid level. It’s just a vocabulary list. Go down level if you feel like it.
- Counting of “known” Hanzi
- Custom vocab list, and custom skip list
- Online text parser
Currently, it’s a desktop app, and it’s kinda unlikely that I would make it into a website or include Japanese (as it doesn’t have much benefit to myself). Anyway, contributions welcome.
Also, Happy Chinese New Year
