Self-report & Anki import
Kumi does not make you start over. Self-report or import from Anki, and its trust-based system lets you skip what you already know instead of starting from zero.
Kumi does not make you sit a placement test. It trusts you to say what you already know, and it is completely fine if that is nothing (yet). Kumi quietly verifies and sharpens your starting point over time. There are two ways to start: tell Kumi directly, or import your history from Anki.
Most apps assume you are a blank slate and march everyone from the very first character, no matter how much Japanese you already carry with you. Kumi does not. We have enough faith in our system to sniff out what you genuinely know, so we can meet you exactly where you are. It doesn't matter if you're brand new, coming back after years, or already reading novels. Nobody has to pretend to start over.
That picture is what feeds your KMT in each domain, so getting your starting point roughly right means Kumi can put your study time where it actually helps.
The quickest path is to tell Kumi directly, right from the dictionary. Open any concept and use its menu to mark "I already know this", or select several at once and choose "Mark known". Kumi marks each one learned, seeds your mastery across every way of knowing that concept, and drops it into your reviews at a sensible starting interval.
It works concept by concept, within the domain each one belongs to, and it is fully reversible. You can reset a single concept, or reset your learning entirely.
Find the concept in the dictionary
Look up any word, kana, radical, kanji, or grammar point you already know.
Mark it known
Open the concept menu and choose "I already know this", or select several concepts and choose "Mark known".
It joins your reviews
Kumi seeds your mastery for that concept and schedules it for review, so it stays fresh from day one.
Marking known is not the same as earning it
Self-reporting does not grant XP or streak credit. It exists to set an accurate starting point, not to hand out points, so there is nothing to game by clicking it.
If you have studied in Anki, you can bring that progress with you instead of starting over. When you first set up Kumi, or later from Settings under Knowledge, upload your Anki export. Kumi reads your reviewed cards, matches each one to the matching Kumi concept, and carries over your Anki scheduling so your review timing picks up close to where you left off.
Kumi keeps your Anki stability and difficulty and next-review dates for each matched concept, rather than throwing them away. For the ways of knowing a concept your deck did not cover, it adds a modest starting point so those still get gauged as you review. Cards it cannot confidently match to a Kumi concept are skipped rather than guessed, and your deck structure is rebuilt as saved lists so nothing feels lost.
Export your deck from Anki
In Anki, export as a .apkg file, including scheduling information.
Upload it to Kumi
During onboarding, or later in Settings under Knowledge, drop the file into the import panel.
Confirm any ambiguous matches
When a word could map to more than one entry, pick the right one so your progress lands on the correct concept.
Kumi rebuilds your progress
Your matched concepts arrive with their mastery and schedule, and your decks come across as lists.
This is why trusting you is safe. When you self-report or import, Kumi treats it as a starting guess with no confidence behind it yet. Your very first real reviews carry far more weight than the initial claim, so if you marked something you did not quite know, your level settles quickly, and it corrects upward too if you sold yourself short.
Kumi is watching far more than right or wrong while you review, which is what lets a quick claim get corrected so fast. What is mastery? explains exactly how that gauging works.
Trust, then verify
Every review refines the estimate. After a week, Kumi's picture of your Japanese is sharper than your own guesses.
Mastery explained
What is Mastery?
In Kumi, mastery is a 0 to 100 score for a single concept, built from every way you can know it. It grows when you truly recall something, and it fades when you stop reviewing, the way real memory does.

KMT explained
What is KMT?
KMT (Kumi Mastery Tiers) is a 1 to 10 mastery scale Kumi tracks separately for each domain. Unlike JLPT levels, which have no official study list, it reflects what you have actually mastered and decides what to study next.
