LevelUp – WaniKani-style Level System for Any Deck

Tired of Anki throwing new cards at you every day whether you're ready or not? This add-on brings a WaniKani-style level system to any deck.

How it works

Your deck is automatically split into levels of 20 cards each. Only your current level is active – everything else stays locked. Once 90% of your current level's cards reach an interval of 7+ days, you can level up and unlock the next 20 cards.

Past levels have no influence on leveling up, so a forgotten card from Level 3 won't block your progress on Level 8.

Cards that reach an interval of 120+ days (~4 months) are permanently Burned – tagged and suspended forever, just like in WaniKani. You've truly learned them.

Features

• Automatic level assignment – just point it at a deck, no manual tagging needed
• Level-up check on demand – you decide when to check, not the app
• 90% threshold – one difficult card can't block your entire progress
• Burn system – cards you've truly mastered disappear permanently after ~4 months
• Works with AnkiWeb sync – study on your phone, manage levels on desktop
• Fully configurable – cards per level, interval threshold, burn threshold and level-up percentage are all adjustable

Setup

1. Install the add-on and restart Anki
2. Go to Tools → LevelUp → Setup Deck
3. Select your deck – cards are tagged and all but Level 1 are suspended automatically
4. Study normally, then check Tools → LevelUp → Check Level Up whenever you feel ready

Configuration

Edit the CONFIG dict at the top of __init__.py:

CONFIG = {
    "level_size": 20,            # cards per level
    "min_interval": 7,           # days before a card counts as ready
    "level_up_threshold": 0.90,  # 90% of current level must be ready
    "burn_interval": 120,        # days until a card is burned (~4 months)
}

Notes

• Tags used: levelup::level1, levelup::level2, ..., levelup::burned
• State is saved locally in levelup_state.json in the add-on folder
• Running Setup Deck again on the same deck only processes new untagged cards
• Requires Anki 23.10 or newer
