Just drill any units, repeat freely, and use Anki or RemNote for spaced repetition.

Pacing & personal analytics
Includes raw answers, response timing, typing edits, hints and audio replays. Turning this off keeps learning progress and grades, but omits optional answer and timing details. No IP address, browser fingerprint, screen size or precise location is stored in learning events. Essential service infrastructure may maintain separate security logs.
Manage known & pinned words
Known is your preference, not a mastery score. All mode includes every word. Pinned words stay eligible in Focused and My troublemakers.
New words keep flowing. Difficult words can wait. BrainForge schedules long-term review for account holders.
See what sticks.
Your practice record and optional follow-up checks live here.
Your vocabulary runway
MNN Units 1–50 in BrainForge · a study catalog, not an official JLPT word list.
Every audit gives you a clearer map.
A rapid audit records one no-hint attempt per word. Repair the ones you miss, then check them cold again later.
Unit map
Each tile shows cold checked words out of its BrainForge vocabulary total. Select a unit to prepare an audit.
This graphic combines your saved account audits with newer attempts on this device. Other-device work appears after sync. Anki history is not imported automatically. A cold pass is evidence from the attempted direction, not proof of permanent recall or full exam readiness.
Cloud progress appears after account sync.
Session history & delayed recall
Small, no-hint samples at 15 minutes, 2 hours, next day and 3 days. Comparisons use the actual elapsed delay and matching directions. These checkpoints are optional, not an SRS queue.
Make a plan.
Set a target date and choose a daily review when you are ready.
Vocabulary runway · two deadlines
Core = Focused vocabulary in Units 1–50. After the memorization date, repair core words and optionally add the remaining All-mode vocabulary. This is separate from saved exam coverage; changing runway settings does not change saved exam coverage.
Capacity limits additional introductions, checks and repairs beyond up to 24 due reviews. Estimated minutes now use your completed sessions when there is enough evidence; otherwise they show a wider provisional range. Allow seven days between first introductions and the memorization date for later checks.
Exam goal & daily plan
A saved exam goal raises study priority as the date approaches. It does not change what your memory state says.
Study selections only affect exam coverage when you choose them above.
Make it yours.
Adjust sound, manage account sync, and keep a backup of your work.
Pronunciation audio
Recordings play during eligible prompts. Listening checks play the audio without showing the answer.
Account & data
Checking account availability…
BrainForge stores your answers, timing, errors and review history to personalize study and sync devices. No online service can guarantee zero risk. You may export and delete your account data.
Password
Set your own unique password after signing in. Do not send it in chat or reuse another account’s password.
Backups & how it works
Progress stays in this browser. Export a backup to move between devices or protect it before clearing browser data. Account sync is available only when the site’s secure backend is configured.
Space continues introductions and feedback. Enter submits typed answers. In text fields, spaces and editing keys stay native. Outside text fields: C correct, H hard, D wrong / don’t know, S override, P park, X skip, U previous, K already known, I hint, R replay pronunciation, Esc pause. Tab moves from typing to the controls.
Mnemonics are memory aids. If the checker misses a valid synonym, use “Self-correct” after comparing with the answer. That correction is recorded, without teaching the checker a potentially wrong synonym.
“Passed this session” means successful recall in both directions and a later check. It is not permanent mastery. Keep using Anki for long-term review.
Learning design & research notesThis word needs a new approach. Say it aloud, picture its meaning, or park it for another session.
