Question 1

Is Wanilog free?

Accepted Answer

Yes. Wanilog is free, has no account or signup, and is supported as a personal side project. You only need a WaniKani API key, which you keep in your browser.

Question 2

Does Wanilog need my WaniKani password?

Accepted Answer

No. Wanilog uses a personal access token generated from WaniKani's API v2 settings page. Your WaniKani password never leaves wanikani.com, and the token is kept in your browser's localStorage.

Question 3

Does my WaniKani API key ever leave my browser?

Accepted Answer

Almost never. Your API key normally stays in your browser and talks directly to api.wanikani.com. One exception is when you tap "Create shareable link" on the /share page: your browser hands the key off to Wanilog for that one click so a short-lived function can confirm you actually own the WaniKani username you're publishing under. Verification sends the key to wanilog.com, where it is stored to help troubleshoot account issues and deleted when you unpublish, though other key-verifying features (like achievement sync) store it again unless turned off. The disclosure is signposted next to the button, and the request only happens after you click it.

Question 4

How does Wanilog predict my WaniKani finish date?

Accepted Answer

Wanilog measures the duration of each level you have already completed, takes the median (which resists outlier weeks), and projects that pace across your remaining levels up to your goal. Recent levels weigh more heavily, so a change in pace is reflected quickly. You can also drag a what-if slider to see how a faster or slower pace shifts the finish date.

Question 5

Is Wanilog a replacement for wkstats?

Accepted Answer

Yes. Wanilog covers the same ground as wkstats.com, rebuilt phone-first, and adds a statistical finish-date projection, JLPT and Joyo coverage, and a leech trainer. It runs in your browser.

Question 6

How does Wanilog compare to WaniTrack?

Accepted Answer

Wanilog covers the same workload-forecast and leech-tracker ground as WaniTrack, and adds a statistical finish-date projection and JLPT / Joyo coverage. WaniTrack is self-hostable and MIT-licensed; Wanilog is hosted-only.

Question 7

Does Wanilog work offline?

Accepted Answer

Yes. After your first sync, Wanilog caches your WaniKani data locally and works without an internet connection. Install it to your home screen or dock as a Progressive Web App and it launches instantly, even on planes or the subway.

Question 8

What counts as a "learned" kanji on Wanilog?

Accepted Answer

Anything at Guru I (SRS stage 5) or higher. That matches WaniKani's own "passing" threshold - the cutoff WaniKani uses to count kanji toward the 90% rule for levelling up. Apprentice items (stages 1 through 4) are in-progress, not learned, and don't count yet.

Question 9

Why does my next WaniKani level take so long?

Accepted Answer

WaniKani requires 90% of the current level's kanji to reach Guru I before you can advance. The minimum path from a fresh lesson to Guru I takes around 3 days and 10 hours on the default SRS (around 1 day and 13 hours on the accelerated SRS used in levels 1 and 2). Kanji that depend on unfinished radicals or earlier kanji can stack additional days on top.

Question 10

What are the WaniKani SRS intervals?

Accepted Answer

Apprentice I = 4h. Apprentice II = 8h. Apprentice III = 23h (around 1 day). Apprentice IV = 47h (around 2 days). Guru I = 7 days. Guru II = 14 days. Master = 30 days. Enlightened = 120 days. Burned items leave the review queue. The wait shown is the time you spend at that stage before the next review. Levels 1 and 2 use an accelerated schedule that halves the Apprentice waits.

Question 11

What is a "leech" in WaniKani?

Accepted Answer

A leech is an item you keep getting wrong despite repeated reviews - it eats your time without making real progress. Wanilog's Accuracy page surfaces leeches, ranks them by how recently you slipped, and offers a flashcard trainer mode so you can drill the worst offenders in one focused session.

Question 12

Does WaniKani cover the JLPT?

Accepted Answer

It covers N5, N4, N3 and N2 completely, and 79% of N1 (971 of 1,232 characters). The four covered tiers finish at different points: N5 by WaniKani level 16, N4 by 27, and N3 and N2 both at 51. What N1 leaves out is mostly jinmeiyo name kanji. Wanilog's JLPT coverage page breaks all of this down against your own progress so you can see how much of each tier you have taken to Guru.
