Hey everyone!
I wanted to share a tool I just finished building. It’s an OpenClaw skill that syncs your WaniKani progress data locally so you can run queries, generate stats, and get insights.
What it does:
• Syncs your assignments, review statistics, level progressions, and subjects (kanji/vocab/radicals) to a local SQLite database
• Incremental sync support (only fetches what’s changed since last sync)
• Query tools for common reports: leeches, SRS distribution, level timeline, accuracy by type
• Full SQL access for custom queries
Example queries you can run:
• Find your worst leeches (items with weak streaks that keep falling back)
• See SRS stage distribution across all your items
• Track how long you spend at each level
• Cross-reference with kanji readings to find problem areas
Multi-platform tracking:
I also built a similar skill for Bunpro (Japanese grammar), so you can track both kanji/vocab and grammar progress in one OpenClaw instance. The two databases can be cross-referenced - for example, finding which grammar points use kanji you’re weak at in WaniKani. And using this information as input for other OpenClaw actions (like generating graded readings or exercises focused on specific kanji or grammar point)

If anyone tries it or has feedback, let me know!
